Low temperature battery
The low temperature lithium battery is a special battery specially developed for the low temperature defects inherent in the performance of chemical power sources. Adopting innovative design concepts, using advanced formula systems and materials, rigorous process manufacturing processes and methods, overcoming multiple technical bottlenecks, and developing low-temperature lithium battery series products. Low-temperature lithium batteries are classified into discharge energy-type low-temperature lithium batteries and rate-type low-temperature lithium batteries according to discharge performance.
Classification and application of low temperature battery
Low-temperature lithium batteries are classified according to discharge performance: energy storage type low temperature lithium battery and rate type low temperature lithium battery.
Low-temperature energy storage lithium batteries are widely used in military tablet computers, paratroopers, military navigation devices, unmanned aerial vehicles, special flight power supplies, satellite signal receiving devices, marine data monitoring devices, atmospheric data monitoring devices, outdoor video. Identification equipment, petroleum exploration, and testing equipment, railway monitoring equipment, outdoor power grid monitoring equipment, military warm shoes, vehicle backup power.
Low-temperature rate lithium batteries are used in infrared laser equipment, glare-type armed police equipment, and acoustic armed police equipment.
Low-temperature lithium batteries are divided into application areas: military low-temperature lithium batteries, industrial low-temperature lithium batteries.
Divided into three series according to their use environment: civilian low temperature battery, special low temperature battery, extreme environmental low temperature battery,
A. civilian low-temperature lithium battery: -20 °C battery 0.2C discharge accounted for more than 80% of the rated capacity; -30 °C battery 0.2C discharge accounted for more than 50% of the rated capacity;
B. Special low-temperature lithium battery: 0.2C discharge of -40°C battery accounts for more than 80% of rated capacity; at -50°C, battery 0.2C discharge accounts for more than 30% of rated capacity;
C. Extreme environment low temperature lithium battery: When the temperature is -50 °C, the battery 0.2C discharge accounts for more than 50% of the rated capacity.
