Performance characteristics of lithium polymer battery：
At present, the working performance index of polymer lithium ion monomer battery is working voltage is 3.8V, mass specific energy address is 50W·h/kg, volume specific energy is 246W·h/1., specific power is 315W/kg, cycle life is more than 300 times, self-discharge is less than 0.1%/ month, Working temperature -25 ~60℃, charging speed LH up to 80% capacity, 3h up to 100% capacity. Compared with liquid lithium ion battery, it has many obvious advantages such as good safety performance, higher miniaturization, ultra-thin, lightest, wider applicable temperature range, small self-discharge, high energy density and low cost, which makes it an ideal power battery. Especially good safety performance, polymer lithium battery because there is no u liquid problem, in the structure of the aluminum flexible packaging. Liquid lithium-ion batteries, on the other hand, require a metal casing and are prone to explosion. Lithium polymer batteries will inflate at best. And the design of its protection line can be simplified accordingly, so as to save its cost. Its shape can be customized according to need, the thickness can be made very thin, so that the application field is quite wide. Because polymer lithium ion batteries are flexible solid polymers, the metal lithium tip is sealed in the battery, so that it can still work normally at higher emperatures. The safety of the battery has also been proven in crash tests.
