The rate-type low-temperature lithium battery is used for infrared induction laser weapon equipment, strong light weapon police equipment, acoustic material weapon police equipment.
2. Low-temperature lithium batteries are mainly divided into military low-temperature lithium batteries and industrial low-temperature lithium batteries according to their application fields.
3. Low-temperature lithium batteries are classified as follows according to the usage environment:
-20c civilian low-temperature lithium battery: -20c battery discharge accounts for 90% of the rated capacity; -30c battery discharge accounts for 85% of the rated capacity;
-40c special low-temperature lithium battery: -40c battery discharge accounts for 80% of the rated capacity;
-50℃ extreme environment low temperature lithium battery -50℃ battery discharge accounts for more than 50% of the rated capacity;
4. According to the natural environment of its application, it is divided into three series: low temperature lithium battery for civilian use, special low temperature lithium battery and low temperature battery for extreme environment.
Civilian low-temperature lithium battery: -20c battery charge and discharge account for 80% of the short-circuit capacity; -30c battery charge and discharge account for 50% of the short-circuit capacity;
Special low-temperature lithium battery: -40c battery charge and discharge account for 80% of the short-circuit capacity; -50c battery charge and discharge account for 30% of the short-circuit capacity;
Extreme environment low-temperature lithium battery: The battery discharge at -50°C accounts for more than 50% of the rated capacity.
Advantages and effects of low-temperature lithium batteries
Low-temperature lithium batteries have the advantages of light weight, high energy density, and long service life, and are widely used in various electronic products. Among them, low-temperature rechargeable lithium batteries have the advantages of simple packaging, geometric design of rechargeable batteries, thin ultra-light fibers, and high safety factors.
General civilian rechargeable batteries-20c cannot be used, and low-temperature lithium ion-50c can generally be used. At present, low-temperature rechargeable batteries are generally applicable to natural environments below the temperature. In addition to power supply systems, mobile chargers, data signal switching power supplies and driving power supplies for small and medium-sized electromechanical equipment, it is also necessary to use low-temperature rechargeable batteries and other on-site switching power supplies for low-temperature characteristics.
