Low temperature lithium batteries use VGCF and activated carbon with a specific surface area of (20000 ± 500) m2/g as additives and their matching positive and negative electrode materials. Special electrolyte is injected with special additives to ensure the low-temperature discharge function of lithium batteries. At the same time, the 24-hour volume change rate is ≤ 0.5% when stored at a high temperature of 70 ℃, which has the safety and storage functions of traditional lithium batteries. Its uses include: power supply for military equipment, aerospace, deep-sea diving aerospace equipment, polar scientific research, adventure equipment power supply, cold belt rescue, disaster relief power supply, cold clothing, cold shoe power supply lights.

　　According to discharge performance, low-temperature lithium batteries are divided into energy storage low-temperature lithium batteries and multiple low-temperature lithium batteries. Low temperature energy storage lithium batteries are widely used in military tablets, paratrooper equipment, military navigators, drone reserve power supplies, special navigation instrument power supplies, satellite signal receiving devices, ocean data monitoring equipment, atmospheric data monitoring equipment, outdoor video recognition equipment, oil exploration and testing equipment, railway monitoring equipment, outdoor power grid monitoring equipment, military thermal shoes, vehicle backup power supplies, etc.

　　Low temperature multiple lithium batteries are used in infrared laser equipment, strong light armed police equipment, and acoustic armed police equipment. According to the application field, low-temperature lithium batteries are divided into military low-temperature lithium batteries and industrial low-temperature lithium batteries.
