Ultra low temperature battery

　　With the development of society and science and technology, the demand for low-temperature batteries is increasing, and the demand for ultra-low temperature batteries is more obvious. Low temperature batteries are generally divided into civil low-temperature batteries, special low-temperature batteries, and extreme environmental low-temperature batteries. Low temperature lithium battery for civil use is generally - 20 ℃ to 30 ℃; Special low temperature lithium battery: - 40 ℃ to - 50 ℃; Extremely low temperature batteries are generally above - 50 ℃. Generally, the temperature exceeding that of civilian batteries belongs to the category of ultra-low temperature batteries.

　　The low-temperature battery developed by Shenzhen Battery Co., Ltd. has a minimum operating temperature of - 50 ℃, which belongs to the category of ultra-low temperature batteries. The ultra-low temperature batteries of the Company include low temperature lithium polymer battery, low temperature lithium iron phosphate battery and low temperature nickel hydrogen battery. Today, we mainly introduce - 40 ℃ ultra-low temperature lithium polymer battery and - 50 ℃ ultra-low temperature lithium iron phosphate battery.

　　After long-term research, development and test, the low temperature lithium iron phosphate battery has possessed proprietary formula and innovative technology. By using proprietary electrolyte formula and other special functional raw materials, combined with leading innovative technology, the battery can still discharge efficiently at extremely low temperatures. Customized low temperature lithium iron phosphate battery can be widely used in military equipment, aerospace industry, diving equipment, polar scientific investigation, power communication, public security, medical electronics and other low temperature fields.

　　Low temperature lithium polymer battery uses proprietary battery raw material formula and innovative manufacturing technology, which can effectively improve the discharge performance of the battery in low temperature environment, reduce the internal resistance of the battery, and achieve high-speed discharge. Therefore, low-temperature batteries have longer life and stronger power. The discharge capacity of the low-temperature battery is still more than 80% when discharged at 0.2c at - 30 ° C, which is also one of the core technologies of. Low temperature lithium polymer battery has the following advantages.

　　1. High low temperature discharge performance, the minimum discharge temperature is - 50 ℃ and 0.2C, and the efficiency is more than 60%; At - 40 ℃, the discharge capacity reaches 80% at 0.2C;

　　2. Wide operating temperature range, - 50 ° C to 50 ° C;

　　3. Excellent low temperature cycling performance, charging and discharging at 0.5C at - 30 ℃, and the capacity remains above 85% after 300 cycles;

　　4. High safety performance, UL/CE/UN certification;

　　5. The size is flexible and can be customized in size and shape according to customer requirements;

　　6. Compared with the traditional lithium polymer battery, the discharge temperature limit of - 20 ℃~60 ℃ has been broken.

　　7. It has the capacity of mass production and good battery consistency;

　　8. It can generate large current at - 50 ℃ and maintain large capacity;

　　9. It can still maintain its excellent performance under - 50 ℃ working environment;

　　10. It can be widely used in cold climate and military equipment.
