There are two classification of the performance, one is storage low temperature li-ion battery, another is discharge rate low temperature li-ion battery.
Low temperature energy storage lithium battery is widely used in military PC, paratrooper device, military navigation instrument, UAV backup start-up power supply, special AGV instrument , satellite signal receiving device, marine data monitoring equipment, atmospheric data monitoring equipment, outdoor video recognition equipment, oil exploration and testing equipment, railway along the monitoring equipment, Power grid outdoor monitoring equipment, military heating shoes, car backup power supply.
Low temperature discharge rate lithium battery is used in infrared laser equipment, strong light armed police equipment, acoustic armed police equipment.
Low temperature lithium battery is divided into military low-temperature lithium battery and industrial low-temperature lithium battery from the application.
