Sowing the seeds of electrolyte “missile”

According to the United States well known writer of science Marchell Blain series of articles in the lithium batteries in the introduction, the vast majority of the explosion of lithium caused a short circuit, and the specific reasons including the load voltage / over-current use of aging.

The lithium battery manufacturing process, because the manufacturing process itself imperfect, it is easy to be isolated between the two poles, leaving a metal powder, copper foil, pieces of foil. The angle is provided in the battery as fever (more common in long-term use or load), like water boiling in a grain of rice, as in the electrolyte to make the random thermal motion. If you happen to have the battery positive and negative particles or debris near the middle of the diaphragm, it could create a perforating fracture triggering micro-short circuits. As electrolyte batteries are flammable organic micro-short circuit cause an explosion in May, burns and other accidents, generally the following three cases:

1. Sparks ignited the electrolyte, and thus lead to a catastrophe to come into contact with the body in plastic and flammable, causing a fire;

2. Experiencing an increase in temperature caused by the battery, the battery inside the space is small, perhaps due to increased pressure to explode;

3. Low temperature rise inside the battery, the battery case to melt gradually, so that the leakage of corrosive electrolyte.

Security Issues lithium batteries can not stop now, because then the manufacturing technology advanced, will inevitably lead to planting seeds in the electrolyte “missile”. Note that the formal production of lithium batteries and sales of high standards of lithium batteries of acceptable quality, the number and size of debris have been controlled within a small, very low risk of perforation of the diaphragm cell outside the Shell also used flame retardant material, are not prone to fires.

The explosion proof lithium battery of measures

Security Issues lithium batteries, the battery manufacturer, well aware, then what they used explosion proof action? Li-ion batteries for laptops, for example, its operating principle is as follows: lithium batteries near full charge and discharge almost empty when the voltage drop, the control circuit detects this situation, notify the protection circuit cut power to avoid overcharging or excessive discharge, so as not to shorten battery life.

The lithium batteries have a current portable multi more comprehensive mechanism level protection, even in the charger, laptops unusual circumstances, the laptop battery can also be converted to the status of automatic protection is generally not explosion. But once the control circuit protection circuit and the ability to work reduced hours, the battery on the point of “dangerous” file. Mobile phones and other electronic products, battery lithium and mechanisms of protection against discharge, similar to that.

Do not need “at arm’s length”

In recent years, lithium-ion electronics explosions often newspapers, has caused much panic among consumers, some people for their own cell phone, MP3 pricing often “at arm’s length”, also because of fear, while just a long term will be set aside laptop battery, lead scrap. However, the results of the survey, the majority of outbreaks of lithium batteries are the result of the attention of the user pays for safety tips such as unauthorized modification, use of non-correspondence charger, battery placed in extreme environments such as decisions.

Should be stressed that the technology of lithium batteries as a sort of after 30 years of study, has successfully commercialized the technology mature, its security is guaranteed. The regular brands of lithium batteries at the factory have been numerous procedural road test after being sold and the mechanism of feedback to recall the product over time.

United States Transportation Security Administration (TSA) has implemented the recommendations of the safe use of lithium batteries:

1. Use the original charger: Li-ion battery charging time is the period of heavy bombardment. That charger original battery is compatible with the battery charger to ensure better security.

2. The use of reliable battery, try to buy original batteries, not to save money to buy “second hand goods”, these batteries may be to maintain and more reliable than original batteries.

3. Do not place the battery in the extreme environments: high temperatures, collisions, etc. are all important causes of battery explosion, as far as possible, so that the battery is in a stable environment, away from areas at high temperatures.

4. Do not change: Many young people like their phones to “cosmetic”, but it was “bold but prudent” in order to transform mobile phones into themselves. However, it can easily lead to accidents inappropriate alteration. The phone is a sophisticated communications equipment in the design, manufacturers will have on its security, strictly textual research. After modification, the battery may be not to consider the environment before or increased security risks.

Employment in this industry for 10 years, the company has a camera around 10 sets of different brands of batteries per batch, equipment acquisition and maintenance has always hands are here today to talk battery.

         I was sony390P Sony original battery, original hand-held rechargeable camera battery purchased in 2002, the battery has been significantly decreased, the use of the public sector can not 1 hours old stuff no one to talk .

          My Sony 300P is the battery depending on Viagra in 2003, bought five years, using a 4 very good hours of my battery DeLay dvc200 yes 10000, travel charger, bought in 2003, first two days of use, about 2 have broken - the story here on the capacity of the back slowly.

          My other is dvc200 Yasuharu batteries, laptop desk stand, 03 bar of my 250 batteries Sony Tianxu East Anton mouth, but in 2003

         My Sony 190p is the stack 970, there is original, there are victories goods, but also have the Sony battery-electric plate and other changes, many, more than 10 pieces.

      Some of these machines are used machines, buy or ask the owner, or search for materials, some large machines with battery in the purchase of camera used.

        190p with original batteries with Sony about 1000 yuan, the use of very good course, purchased in 2002 and today still use the battery is not enough, e-scrap market - Zhejiang Road Bridge equipment market, there are places selling the waste abroad, come in a lot of Sony original battery, it will be forced to battery panels use laptops Sony batteries replaced electromagnetic very cheap 100-150 1, 2003, I took a little good, even now, most of the use of the property only to the recession individual emotion, the quality of the original panels from Sony.

        Later, over 190 cameras and others, and I feel that home is too expensive, can not find the type of modified cells, and purchase a product wins 970F battery charger plug Sony Dual, full incentive to 800 minutes ecstasy Who knows time is false, but a few months is also available with good, time is very long, more than shooting a wedding there is no problem, you can win goods seem not sustainable for 45 days five months are spent three bad, are also some more in 2012, but the products have a good victory, a one-year replacement, a replacement is said not now, but I spent many years as both a product wins Taobao Mall, or purchase, bad Naqu change, therefore, the use of both a new battery, and once for a friend (Shaoxing Shanshan digital) look for the three batteries, or ensure there is too much for my friends to get the dealer may be something wrong with the product management victories - they also had to change, but the issue of vulnerability, it reflects the product wins first-class after-sales service, product quality and not much - poor battery was able to pass a new battery. This product wins said is absolutely a good choice, can change a
         However, many users may want to call me, because the success we are too many in the supply of batteries, online seems to have been translated into good enough, cheap and easy to use, the original report by Sony 970 media a lot, but we Jing are most frequently the use of batteries. This is a good product that wins the battery that is not good, I Yiwuyishi to say.

         Bought a new field of Scud and some other brand name, using the two months that does not work, will not change. Forget, do not buy it, and that these semi-professional batteries so much, really feel and quality of life and imports there are gaps, they said original batteries in the foundry house, you learn Japanese in May these plants down, the best people in Japan, bad for the country, but he added the leadership of other major battery manufacturers Sony F970 battery after a 500, I think the quality will be good to see the show before, asked not to sell the house, pity.

           While talking about the quasi-professional battery big machine, these cells fired fewer contacts with their counterparts in marriage - we have a better understanding, but also to use broadcast quality equipment to their counterparts of Reference. Original Sony batteries do not seem how to 390p in 2003 to purchase the original units are used, plug the drive felt the burden, but also, his life has dramatically decreased, which can use a half-hour, there is a 1 Less than an hour, barely can use the bar! Get new no problem with making a difficult marriage, but also to maintain power at the ceremony, the use of multi-bit machine during the day is responsible for the apprehension of some scenes sequences 10.

        Sony 300p visual Viagra battery 2 is not bad, using five or six years, the situation is good, four hours without a problem, special attention at a time in the exhibition and sale is also responsible for a small van 15951807968 exceptionally warm exposure and returning to Xianju and we tried to call for the promotion of its batteries. I believe that as the Viagra of the battery well. Because it seems that all may serve television stations Viagra Xianju, and have the opportunity to buy too.

            Oriental Sovy250p Asahi battery two days, from Nanjing, a film company bought the camera together two to four hours, no problems have purchased less than two months, and once employees to unplug the charger burned, immediately with manufacturers, the eastern Tian-Xu Beijing, Mao Yi 15,011,200,030.13370188367, very hot, let me send more, so I Shunfeng mail the next day went, and Mao Yi called me and said models charger more, it found pipe fittings, repair of an immediate response to me, and I think it started in do not know how much money, but also a feminist! Can not ah! Who would have thought that a few days Maoyi contact me: Just 120 of money, but also added a line source over the adapter directly to me. I am happy evil is not to be happy to fill it!

          DV200 battery Yasuharu is produced in Zhengzhou, 2, Tangshan, in collaboration with the video camera to buy. To purchase power switch does not work, and Xianju search appliance repair Do not put directly to the Department. Just start is also very good, three or four hours, once again, during the shooting, the battery indicator blinks crazy. He recorded again, as they will be returned along with batteries and chargers, Zhengzhou Jia Ding Liu .0371 to 63,316,142, and soon returned to me repaired, or 240 yuan of money, delivery of 70 yuan on the ruthless. Yasuharu service is good, keeping the old factory in the same way, and I said, this old type, take time.

        Another Vandy dvc200 cell, and the camera and in Sichuan has bought time is also expected in 2003, has acquired a very good use for more than four hours, spent several years sees no recession, but A few days ago, they mad one days flash can also be recorded. The staff knows not loaded incorrectly, 10000 DeLay plug the battery into Yasuharu from, or how the two can not be used simultaneously, and can not be filled, 10000 DeLay on the battery charger can plug into Yasuharu load , as I put the battery charger is plugged Tianxu up on the Viagra, you can, I think, and charger are a few changes to V, the reason must be able to practice, but different cells and charger is better not Hunchong psychologically safe.

       10,000 DeLay contacted Li Shu-chun, phone asked me for years and I have said in 2003. She said you would use to end the life … … Gordon, I opened the door to come a time,,,, I said it was two bad fast at the same time, I think we can repair. She said that you send. So I Shun Feng Express, I thought taking the eastern Tian-Xu, Yasuharu no Yam, 10000 DeLay did not see the life that I will not let me buy a new battery put in it! After a few days and nobody answered the phone 0371-67896576 13939036337, received today in Shanghai Company 10,000 Tel 021-54168031 delay a little young, first of all say that you better buy a charger repair bad but I do think not: the charger before sending me to plug to charge the battery too Yasuharu A! how to say I have a bad charger, and just understanding, and told me to sell the battery? I said I have almost all the major manufacturers of household batteries are in the same year purchased, they are not bad, 10000 DeLay is bad, and the charger is bad, I would not buy one million purchase DeLay A. I can buy Yasuharu, and can save me a charger Ah! I said, how you get to be so high, 600, days before the eastern continuation of the Asahi and Yasuharu or two hundred, I tell you refer to the bar … …. this young and I’m always just then the old models, and research parts, a number of how much power is needed to talk to him … … fast speed, making service, so how can you get? ? ? Then I type faster than him, I said I was a year to attend the show, I think your very good brand 10,000 late, but the service seems less than other manufacturers’ Ah! 10,000 DeLay to allow me to buy a new battery to save costs and maintenance cost, simply said that I could not repair necrotic, and I said I would not buy 10,000 Di on drums, not for reasons today, but my hands have other chargers, I have a fit of anger, said: You sent back, I can guarantee a solution, but the low price, say so, my mind thought: I’ll let the foreign waste machine repair roads and bridges. Replace the lithium battery laptop, the estimates are good electrical panel, or simply send Yasuharu Tianxu repair and east, are the manufacturers of batteries, I think that once to know the enemy, how can not repair the file. I think that is something, but manufacturers have already promised to fix a million, I took a ,,,,, DeLay is not absurd to manufacturers this year is busy waiting for 10000 DeLay Reply Pakistan repair problem is bad, there Yasuharu Both are separate batteries. Is also possible that these 2 million batteries are really bad late I did, life has expired.

        Jing media have so many brands of batteries, so we are all new, these chargers and batteries must be of Erwan Yi. Television equipment maintenance is really terrible. Therefore, the shooting does not mean that low price. What have been repaired so many batteries and chargers, two hundred dollars in repairs and can not repair the difference between the sale to buy batteries also reflects the attitude of various battery manufacturers. Here, or against a particular manufacturer, but different manufacturers will be showing the real attitude of service for user information.

Battery Tips (I think we all know)
1. End of battery power and then load the newly purchased application for more than 10 hours, repeated three times
2. Do not use half the battery charge, the number of charging too much loss of life would
3. Do not depleted battery charging, this would reduce the activity of the battery
4. The battery will not charge a long time,,,, Sony’s original theory, a sufficient time to protect others
5. The battery is fully charged will not long keep the charger to discharge the East Rising Sun can charge the battery with the brand. (Yasuharu too) I think that other brands can also be Hunchong ,,,,。

           Video equipment maintenance needs of mind, more equipment, we get a person to maintain, but as far as possible so that all employees are familiar with the equipment in question, rely on each side to understand the maintenance is the correct path: the battery to see is a small device, very important.

The chairman of Lenovo, the world’s number four PC maker, shared Chinese revolution-spirited slogans and the unlikely story of his company’s growth out of a government-managed economy in a motivational speech to Chinese small business owners on Friday.

Liu Chuanzhi, one of 11 former government researchers who founded the predecessor to Lenovo in 1984, recalled how the company fought through trade barriers, high component prices and domination by foreign brands in a talk that highlighted how fast China’s economy has grown in the last three decades.

“In 1993 almost the whole market was foreign-branded computers,” Liu said at the forum for small and medium businesses in Hangzhou, a scenic city in eastern China.

Lenovo faced tough odds even though its founders were from the Chinese Academy of Sciences, a Chinese state-controlled institute for national research projects. The academy gave the company founding capital of 200,000 yuan, or about US$30,000 today. That sum, far from enough, would not have been enough to buy three computers in China in the 1980s, Liu said. Things only grew worse when the company was scammed out of two-thirds of the money, he said.

“When we came out, we not only lacked funds but also had no idea what to do,” Liu said.

Lenovo, formerly called Legend Group, was founded early in China’s process of market economic reforms and had to work in a tightly regulated environment. China tried to protect domestic PC makers in the 1980s by charging a massive 200 percent tariff on foreign computers, said Liu.

“The result of this protection was that foreign computers were very difficult to get into China and could only be smuggled, but China also could not make its own computers very well,” he said. The low quality of components such as hard drives in China also hindered the company, he said. Lenovo’s first PC did not reach the market until 1990.

Lenovo struggled with low margins even as it built market share against foreign brands like IBM and Compaq in the 1990s. Government regulation also continued to slow the industry’s growth. Chinese residents had to register with the government to become Internet users even late in the decade, said Liu.

Lenovo’s global presence gained a huge boost when it bought IBM’s PC unit in 2005. The company’s sales in developed markets have since slumped in the global economic recession and it has restructured to bring its focus back to China and other emerging markets. Lenovo today is the top PC vendor in China.

To succeed like Lenovo, companies must “love to battle, know how to battle, and conduct campaigns with order,” Liu said, using language reminiscent of “The Art of War,” an ancient Chinese book on military strategy by Sun Tzu.

Liu also emphasized the importance of company culture, describing Lenovo’s as an example. “Make the company’s interests the top priority, seek truth in forging ahead, take the people as the base,” Liu said.

Chinese president Hu Jintao has promoted the slogan “take the people as the base” as a part of socialist theory. Liu attended a Chinese military college in the 1960s and worked on a Chinese farm during the Cultural Revolution, a chaotic period when many graduates were sent to the countryside for re-education

Despite the tightening of belts all across the globe, computer manufacturers are obsessed with the concept of style, building ultra-thin, expensive machines fat with flair and aimed toward the budgets of the elite. The tease of Dell’s latest iteration of its Adamo laptop — which purports to be even thinner than Apple’s MacBook Air — is another pistol shot in an increasingly competitive race to build the sexiest, thinnest, heroin chic laptop out there. But the race feels hollow and nearly pointless.

Image copyright Dell
Details on Dell’s anorexic Adamo are scant. The Web site says only that it is 0.4 inches thick, compared to the Air’s relatively bloated 0.75 inches. The Adamo’s screen measures 13 inches diagonally, and the laptop weighs 3 to 4 pounds, just like the Air.
Keep in mind that Dell insisted on calling the product a “design concept” and wasn’t clear if it actually plans on producing a laptop that thin. Still, what’s important is that the idea is there. Dell believes there is still a market for high-priced luxury laptops, and competitors will very likely trace Dell’s footsteps and build gaunt machines of their own.
Already Intel is introducing low-power processors designed for ultra-thin laptops. The Intel Pentium SU2700 is bred for use in sleek laptops that are as light as netbooks but have larger screens and greater functionality. Samsung released the $2300 X360-34P (catchy name, no?) that weighs only 2.8 pounds. MSI has its X-Slim 340, clocking in at 20mm at its thickest point, slightly bigger than the Air’s 19mm thickness.
So is there actually a market for these devices? Before the MacBook Air price drop, many considered its $2000+ price tag and its lack of features constituting a failure. Dell’s Adamo feels like a stunt, an attempt at winning the Guinness Book of World Records award for thinnest possible laptop. In this economy, it almost seems destined to fail outside of small, elite groups of consumers who are less interested in pinching pennies than they are flaunting sexy tech. Stay tuned for more details on the upcoming Adamo makeover, and keep an eye on how long it actually stays on the market.

Hoping to generate some buzz around its Adamo laptops, Dell showed off an ultra-thin design on Wednesday that could heat up the race between PC makers trying to build the world’s thinnest laptop.

Dell put up a Web page Wednesday showing an Adamo that measures just 9.9 mm (0.4 inches) at its thinnest point. That’s almost half as thick as the current Adamo 13, which measured 16.39 mm (0.65 inches) at its thinnest point.

Dell insisted on calling the product a “design concept,” however, and it wasn’t immediately clear if Dell will actually release a laptop that thin. It said specifications and further details would come at a later date.

The XPS brand is used by Dell for its mid-range consumer laptops and desktops. Dell intends to push the Adamo brand across a range of luxury products, the company has said.

If the device is released it could give Dell a leg up on Apple, whose MacBook Air measures 0.76 inches at its thinnest point. Apple first showed the MacBook Air in 2008, calling it “the world’s thinnest laptop.” Dell launched Adamo in March this year, drawing comparisons with the Air on size and features. Both laptops come with screens around 13 inches and weigh 3 to 4 pounds.

Dell used a similar teasing tactic earlier this year when it put up a Web site to drum up interest in the Adamo 13. Prior to that it had trouble keeping development of the product under wraps. Rumors circulated late last year that Dell was building a laptop to rival the MacBook Air.

The rumor was confirmed when the laptop was shown at the Consumer Electronics Show in January. However, Dell did not reveal product specifications at the time, saying it was showing Adamo to end the speculation about whether it existed.

Sharp Electronics this week introduced a netbook-like mobile device with a 5-inch touch screen that is designed to run Internet-based applications.

The PC-Z1 device is as easy to handle as a mobile phone and provides performance similar to PCs, the company said in a statement. It is designed for an audience that relies mostly on the Web for computing.

Sharp is positioning the PC-Z1 as a “third mobile tool following in the footsteps of notebook PCs and mobile phones to create a new market,” the company said.

The PC-Z1 runs the Ubuntu flavor of the Linux OS, which can start up in as little as three seconds, the company said. Its software includes the Firefox browser to access online applications and Adobe Flash to play YouTube videos. The device also includes applications for users to create documents and spreadsheets, the company said.

The device has a 68-key keyboard for data input. It weighs about 409 grams (0.9 pounds) and offers a 10-hour battery life.

For Internet access, the device includes built-in IEEE 802.11 b/g wireless networking. It has 512MB of RAM and 4GB of flash storage. An additional 16GB of storage can be added through a Secure Digital memory card slot. The device can be used as an e-book reader, for which Sharp will provide content like novels and comics.

The PC-Z1 will go on sale in Japan on Sept. 25, but no price was immediately available. Sharp couldn’t immediately be reached for comment on worldwide availability.

The device has similar attributes to netbooks, which are low-cost laptops characterized by small keyboards and screens between 7 and 12 inches. Most netbooks come with Intel-based Atom processors, but Sharp’s device comes with Freescale’s iMX515 processor, which is based on a reference architecture from chip design company Arm Holdings. The processor is based on Arm’s Cortex-A8 core, which can scale in performance up to 1GHz. The chip supports 3D graphics and can play back high-definition video.

Freescale is shipping its chips for devices it calls “smartbooks,” which it defines as low-cost laptops designed to do netbook-specific jobs such as accessing social networks and running productivity applications. This is the first device to hit the market with Freescale’s chip, a company spokesman said on Friday.

At least one major PC maker has questioned the viability of smartbooks in the consumer space. Asustek Computer CEO Jerry Shen earlier this week said he saw no “clear market” for the Arm-based smartbooks and that his company had no plans to move forward in the segment. The company in June demonstrated a smartbook with Google’s Android flavor of Linux at the Computex trade show. Asus was a netbook pioneer when it started selling Eee PCs in 2007. That line has sold millions of units since then.

The U.S. Department of Homeland Security has released new rules for border agents searching travelers’ laptops and other electronic devices, but the revised guidelines won’t quiet complaints from the American Civil Liberties Union.

The new guidelines, unveiled Thursday, continue to allow U.S. Customs and Border Protection (CBP) and U.S. Immigration and Customs Enforcement (ICE) to search electronic devices during border crossings without suspicion of wrongdoing. Both CBP and ICE are part of DHS.

The new rules were announced by DHS a day after the ACLU filed a lawsuit in an effort to get more information about border laptop searches. The ACLU and other groups have complained that the laptop search policy violates the U.S. Constitution’s Fourth Amendment against unreasonable search and seizure.

The new guidelines are intended to provide more “transparency and accountability” for the laptop searches, said Matt Chandler, DHS spokesman.

The guidelines require CBP to complete a search of an electronic device within five days and ICE to complete a search within 30 days. In addition, agents must take additional steps to inform and educate travelers about the searches, and the DHS Office for Civil Rights and Civil Liberties will conduct an assessment of the policy’s impact on civil rights within 120 days, Chandler said.

The new rules provide a good balance between U.S. security and civil liberties and privacy, Chandler said.

“Keeping Americans safe in an increasingly digital world depends on our ability to lawfully screen materials entering the United States,” DHS Secretary Janet Napolitano said in a statement. “The new directives announced today strike the balance between respecting the civil liberties and privacy of all travelers while ensuring DHS can take the lawful actions necessary to secure our borders.”

But the new rules don’t go far enough, said Catherine Crump, staff attorney with the ACLU First Amendment Working Group.

“DHS’ latest policy announcement on border searches is a disappointment and should not be mistaken for one that restores the constitutional rights of travelers at the border,” she said. “Members of the public deserve fundamental privacy rights when traveling and the safety of knowing that federal agents cannot rifle through their laptops without some reasonable suspicion of wrongdoing.”

The ACLU does not oppose border searches, she added. “But it does oppose a policy that leaves government officials free to exercise their power arbitrarily,” Crump said. “Such a policy not only invades our privacy but can lead to racial and religious profiling.”

CBP has asserted that it can search all files, including financial documents and Web browsing history, on travelers’ laptops and electronic devices “absent individualized suspicion.” The agency does need probable cause that a crime has been committed to seize a device.

In the past 10 months, CBP has dealt with more than 221 million travelers at U.S. ports of entry, according to DHS. CBP did about 1,000 laptop searches during that time, and only 46 were in-depth searches, the agency said.
