The safety problem of lithium-ion battery is the internal heat of the battery. If the heat generated by the failure cannot be released quickly, the battery temperature will continue to rise, and the rising temperature will intensify the chemical and electrochemical reactions between active substances, electrolyte and other components in the battery, resulting in a large amount of heat and gas, which will eventually lead to the thermal runaway of the battery, until smoke, fire, explosion and othe

Lithium battery products for communication energy storage have technical advantages. With the construction of 5G infrastructure, the demand for lithium batteries for communications continues to rise. The 48V lithium iron phosphate battery backup power supply for communication is one of the mainstream development directions of the communication base station energy storage battery. The battery has the characteristics of high energy density, long life, wide operating temperature range, safety and r
