Maintenance free storage battery has great difference from water batteryMaintenance-free better.

When it comes to mobile phone sealed battery, a lot of people think of the Apple iPhone Since Apple iPhone series mobile phone is carried out, more and more android handset makers tend to support no memory card and make no battery exchange design.

1 Activate with high voltage: use a 12V power supply connect a resistance in series with dozens Ohm The anode of resistance connects the battery anode, and cathode of the resistance connects battery cathode.

China Energy Storage News: Lithium ion batteries is a kind of secondary battery(rechargeable batteries) It mainly relies on Li + embedded back and forth between the two electrodes and embedded off to work.

My friends often ask me, nickel metal hydride batteries and the lithium battery, which one is better In fact, it is really difficult to answer this question.

The storage battery100 ah / 12V: it means that the battery capacity is 100 ah, the discharge voltage of the battery is 12VBattery parameters: the definition of A small electric storage battery in mAh nominal capacity (mA h.

Avoid charging at high temperatures if the above specified operating temperature, namely above 35 ° C environment lithium electricity，The battery power will continue to reduce, the battery power supply time won't be long as usual If at that temperature, but also for charging equipment, that will be more damage in the battery.

Series connection needs high power portable devices, which usually made by two or more sections in series for power supply If use high voltage battery, conductor and the switch can be made in small size.

The battery does not need to "activate"The lithium battery doesn't need the first three time charge more than 12 hours Lithium battery has no memory effect.

The electrode reaction of lithium ion batteries dischargeNegative reaction: C6Li - xe - = = C6Li1 - x + xLi + (C6Li lithium atoms embedded graphite to form composite materials)The positive reaction: Li (1 -) x MO2 + xLi++ xe - = = LiMO2 (LiMO2 lithium transition metal oxides)It is ok to change LiMO2 LiFePO4Lithium ion battery anode is lithium metal compounds, usually for lithium iron phosphate (LiFePO4 lithium iron phosphate, phosphoric acid lithium cobalt LiCoO2, etc), the cathode is graphite or carbon (general use graphite), is to use organic solvent as the electrolyte between the cathode.
