Chemical batteries, is across the electrochemical reaction, the positive, the negative electrode material of the active chemical energy into electrical energy a device class. After long-term research, development, ushered in a wide variety of chemical batteries, widely used in the situation. Great as a building can accommodate a lot of great invention, small enough to count the species in millimeters. All the time is not a better life for our service. The development of modern electronic technology, chemical batteries made very high demands. Each chemical battery technology breakthroughs have enabled a revolutionary electronic device. Modern society, people, daily life, more and more inseparable from the chemistry of the battery. Today, scientists are focusing their electrochemical interest as a chemical battery powered electric car niche.

Dry and liquid battery

The distinction between liquid and dry cells is limited to the period of early cell development. The first battery of glass container filled with electrolyte and two electrodes. Has been launched to paste electrolytes based batteries, also known as dry cells.

There are still “liquid” batteries. The size is usually a very large variety. Such as those used as a source of uninterruptible power supply in large stationary lead-acid batteries or solar cells in supporting the use of lead acid batteries. For mobile devices, some using a full-sealed, maintenance-free lead-acid batteries, these batteries have been used successfully for many years in which the sulfuric acid electrolyte is determined by the silica gel or fiber glass suction separator pay.

Disposable batteries and rechargeable batteries

Disposable batteries commonly called “disposable” batteries, because their power runs out, you can not recharge using only discarded. Common disposable batteries, including alkaline manganese batteries, zinc-manganese batteries, lithium batteries, zinc, zinc-air, zinc-mercury batteries, mercury batteries, battery, and hydroxide magnesium, manganese batteries.

Rechargeable battery according to materials and production processes on the different currents are lead-acid batteries, nickel-cadmium batteries, nickel-iron batteries, nickel-hydride batteries, metal, lithium-ion battery. The advantage is a long life cycle, which may be more than 200 full charge and discharge, and some rechargeable batteries power the load higher than most disposable batteries. Ordinary Ni-Cd, Ni-MH battery, the memory effect only, causing inconvenience to use, often cause early failure.

Theory of battery time

The theory of the charging time of battery: battery charger power divided by the output current.

For example, a 800mAh battery, for example, the charger output current 500MA load when the time is equivalent to 800MAH/500MA = 1.6 hours, while the charger shows charging is completed, preferably about half an hour or and should be given to supplement the battery power up time.

Fuel Cell

Fuel cells is the chemical energy of fuel through an electrochemical reaction into electrical energy directly to the camera is using batteries to hydrogen fuel at the anode is produced by oxidation of hydrogen oxidation hydrogen ions, whereas the reduction reaction of oxygen carried to the cathode, and Coming of the anode generates hydrogen ions with water. Oxidation process-reduction reaction can generate electricity. Fuel cell technology, including the existence, in the alkaline fuel cell (AFC), the fuel cell Phosphoric Acid (PAFC) cell proton exchange membrane fuel (PEMFC) fuel cell molten carbonate (MCFC), solid oxide fuel cell (SOFC) and Fuel Cell Direct Methanol (DMFC), etc., whose use of the oxidation of methanol as a positive response to the cell technology fuel, but he is optimistic about the industry and positive developments.

In lady security company advertising these days use mobile battery is very concerned about fat. She told reporters that his company advertising and telephone number of every day, but she bought a cell phone before the battery is not sustainable to use for a year, and now the battery can be used that ‘one day. Reporters ask how to use the battery of Samsung Service Center Miss Zhao, Ms. Zhao said the use of mobile phones should pay attention to:

      Zhao, new phone purchased, the first mobile phone charging time should be longer. Phone purchased on the market in general on the battery is full power (currently the majority of mobile phone battery was activated before use), so customers after the purchase and then charge the battery is first usually the first charge time should be longer, but different brand of mobile phone battery charging time to first use the length and frequency are not the same, the customer must conform strictly the instructions. Such as Samsung, the battery runs for the first time, the price of only 4 to 6 hours, then perhaps, but some brands for the first time required to charge 6 to 8 hours, or even three times in front of a certain time must be sufficiently specific circumstances and needs vary airport in. Currently, the market capacity of mobile phone batteries, 600 mA, 800 mA, 1200 milliamps, etc. In short, the higher the number, the more Long battery mode, but the relatively long duration of load will be more.

      Secondly, the mobile phone battery is preferable to use the full power of not being able after reloading, so as to extend mobile phone battery life. On Miss due to busy every day with two of the battery is fully charged, and sometimes there are one or two batteries of cell phones do not work out, she went to charge. Samsung customer service for Ms. Zhao said, time is not desirable. The lifetime of the mobile phone battery and battery charger has a significant relationship between the number of times, pricing and the higher the number the higher the amount of wear on the battery. On Miss if the battery runs out after charging the battery of his mobile phone a lot of positive and sustainable results.

      Never interrupt the loading process. We used some bad habits: for example, the process of charging the unplug the charger to see what temperature the battery, then reconnect the charger or a temporary emergency, unplug the phone to talk about phone. This will normally lead to instability in the charge cycle, the battery to restart a charge cycle is complete, but before the charging cycle is complete and this charge will reduce the life cycle of the battery of instability.

Lithium-life laptop battery ion is limited, typically 300 to 500 times after repeated loading, they can not be reloaded into the file. Therefore, according to information we are currently in the hands can be seen, to keep the battery “life to the fullest,” or try to run out of power again.
Use an external power supply, do not disconnect the battery. From the perspective of lithium batteries, as rechargeable lithium batteries have a number of limitations, so he got out of the laptop, or can be worn over battery life. But this approach to the laptop itself is very dangerous if a sudden power outage, due to currents and other factors have an impact on the notebook itself. As some of the big names in this field was very good considering, as the ThinkPad is a special built-in technology to protect the battery, only less than 95% of the battery to recharge when it is ibm thinkpad r50 battery
