Low cost, good safety and low temperature performance, but its materials themselves are not very stable, and it is easy to break down to produce gas, so it is mostly used for other materialsMixed use to reduce the cost of battery cells, but its circulation life is attenuation faster, prone to swelling, poor high temperature performance, and relatively short life. It is mainly used for large and medium -sized battery cells. In terms of power batteries, its nominal voltage is 3.7V Essence
