Li-polymer

Lithium polymer battery ( also known as polymer lithium battery ): relative to the previous cell, speaking, high energy, miniaturization, lightweight, is a chemical property of battery. In shape, lithium polymer battery has a thin features, with some products need, making into shapes and the capacity of the battery. This kind of battery, a theoretical minimum thickness of up to 0.5mm.

Characteristic

Relative to the lithium ion battery, lithium polymer battery is characterized as follows:

1 relative, improved battery leakage problems, but not completely improve.

2 can be made of thin battery: the capacity of 3.6V400mAh, its thickness can be thinned to 0.5mm.

3 battery can be designed into various shapes.

4 can be made of a single high voltage: liquid electrolyte battery can only to the number of battery series high voltage, and the high polymer battery itself because no liquid, can be made of single inner multilayer combinations to achieve high voltage.

The 5 discharge, theoretically high out of equal size, the lithium ion battery 10%.

Safety problem

All of the lithium ion battery, either before, or in recent years, including: polymer lithium ion battery, lithium iron phosphate battery and so on, are very afraid of battery internal short circuit, battery, overcharge these external short circuit.

Because, lithium is very active chemically, it is easy to burn, when the discharge of the battery, charging, the internal battery will warm up continuously, the activation process of gas generated by the expansion, the internal pressure of the battery is increased, the pressure reaches a certain degree, such as shell has the scar, which will rupture, causing leakage, fire, explosion or.

Technical personnel in order to alleviate the risk of lithium ion battery, joined is inhibited by lithium element active ingredients ( such as cobalt, manganese, iron, etc.), but these did not fundamentally change the risk of lithium ion battery.

So everyone in the use of various lithium ion battery time, must caution.
