Low temperature lithium batteries are widely used in military plates, paratroopers, military navigation equipment, unmanned aerial vehicles energy storage power supply, special navigation equipment switching power supply, satellite signal receiving equipment, deep sea data monitoring equipment, air data monitoring equipment, outdoor video identification equipment, oil exploration and detection equipment, road monitoring equipment, power grid outdoor monitoring equipment, military heating shoes, vehicle switching power supply. High power low temperature lithium batteries can also be used for infrared induction laser weapon equipment, strong light weapon police equipment, acoustic material weapon police equipment.
What is the classification of low-temperature lithium batteries?
1, low-temperature lithium batteries are divided into: storage type low-temperature lithium batteries, multiplier type low-temperature lithium batteries according to the discharge performance.
2, low-temperature lithium batteries are mainly divided into military lithium cryogenic batteries, industrial lithium cryogenic batteries according to application areas.
3, low-temperature lithium batteries are divided according to the use of the environment as follows.
-20c civilian low-temperature lithium battery: -20c battery discharge accounted for 90% of the rated capacity; -30c battery discharge accounted for 85% of the rated capacity.
-40c special low-temperature lithium battery: -40c battery discharge accounted for 80% of the rated capacity
-50c extreme environment low temperature lithium battery -50c battery discharge accounted for more than 50% of the rated capacity.
4, according to the natural environment of its application, is divided into three series of civilian low-temperature lithium batteries, special low-temperature lithium batteries and extreme environment low-temperature batteries.
Civilian low-temperature lithium battery: -20c battery charge and discharge accounted for 80% of the short-circuit capacity; -30c battery charge and discharge accounted for 50% of the short-circuit capacity
Special low-temperature lithium battery: -40c battery charge and discharge accounts for 80% of the short-circuit capacity; -50c battery charge and discharge accounts for 30% of the short-circuit capacity
Extreme environment low temperature lithium battery: more than 50% of the rated capacity of battery discharge at -50c
Advantages and effects of low-temperature lithium batteries
With the advantages of light weight, high energy density and long service life, low-temperature lithium batteries are widely used in various electronic products. Among them, low-temperature rechargeable lithium batteries have the advantages of simple packaging, rechargeable battery geometry design, ultra-light fiber thin, and high safety factor.
General civilian rechargeable batteries -20c can not be used, low-temperature lithium-ion -50c can still be used in general. Currently, low-temperature rechargeable batteries are generally applicable to natural environments below the temperature. In addition to power systems, mobile chargers, data signal switching power supply and its small and medium-sized electromechanical equipment drive power, but also need to use low-temperature rechargeable batteries and other on-site switching power requirements for low-temperature characteristics.
China has carried out space exploration projects such as BeiDou navigation and moon landing. With the increasing requirements of military communication products on the characteristics of rechargeable batteries, the safety of low-temperature communication is also very important. Therefore, the development and design of low-temperature lithium batteries is of great importance to the development of national defense and space engineering. And also in the continuous exploration of the unknown fields of science and technology, the special properties of low-temperature lithium batteries will play an important role in providing stable power energy for the development of science and technology in China
