Introduction to low temperature battery

　　1. Low temperature lithium polymer battery

　　The low temperature discharge performance is high, the minimum is at -50 ° C discharge at 0.2C, with an efficiency of more than 60%; in the -40 ° C environment, the discharge capacity is 80%; the discharge capacity is 80%;

　　The working temperature range is wide, -50 ° C to 50 ° C;

　　Excellent low-temperature cycle performance, charged at 0.5C at a -30 ℃ environment, and the capacity remains above 85%after 300 cycles;

　　High security performance, passed UL/CE/Un certification;

　　Flexible size, design customization in size and shape according to customer needs;

　　Compared with the traditional lithium polymer battery, the discharge temperature limit of -20 ° C ~ 60 ° C is broken.

　　With the ability of mass production, the consistency of the battery is good;

　　A large current can be generated at -50 ° C to maintain a large capacity;

　　In the working environment of -50 ° C, it can still maintain its excellent performance;

　　Can be widely used in cold climate and military equipment.

　　2. Low temperature 18650 lithium battery

　　At present, the temperature of several stages of low temperature 18650 lithium batteries can be achieved as follows:

　　Within the temperature range between -40 ° C and 60 ° C, the 0.2C multiplier discharge, the effective discharge capacity is 40%to 55%, and the effective cycle of the service life is more than 180 times;

　　Within -30 ° C to 65 ° C, within the temperature range of 0.2C, the effective discharge capacity is more than 65%. It can achieve a 1C multiplier discharge and the discharge capacity of more than 60%; the effective cycle of the service life of more than 200 times.

　　In the temperature range between -20 ° C and 75 ° C, the 0.2C multiplier discharge, the effective discharge capacity is more than 80%, and the effective cycle service life is more than 300 times.

　　The above basic data will be deviated because of the specific usage, because the environmental conditions are complicated and cannot be unified. In terms of application, due to the fixing of battery performance and size, the range of use is relatively small, but its manufacturing cost is relatively low, which is lower than the low -temperature polymer lithium battery and low -temperature iron phosphate battery.
