3.7 volt 18650 lithium battery.Current situation of low-temperature battery industry

　　The types of low-temperature batteries that can be promoted to the market mainly include low-temperature lithium iron phosphate batteries and polymer low-temperature lithium batteries, and these two types of low-temperature battery technologies are relatively mature. The current commercial low-temperature lithium battery with better performance is the lithium cobalt oxide formula lithium battery in low-temperature polymer lithium batteries. Many lithium battery manufacturers, such as Tianneng, Greep Battery, Samsung, and Lishen, have developed their own proprietary battery formulas for low-temperature lithium battery products after years of research and development. They have the following advantages in terms of low-temperature lithium battery performance:

　　(1) High low-temperature discharge performance, -50 ° C to 60 ° C, 0.2C discharge capacity ≥ 65%- 40 ° C to 65 ° C, 02. C discharge capacity ≥ 75%- 20 ° C to 75 ° C, 02. C discharge capacity ≥ 90%; And the growth point technology company has achieved a discharge capacity of -50 ° C to 60 ° C, with a discharge capacity of ≥ 80% at 0.2C- 40 ° C to 65 ° C, 02. C discharge capacity ≥ 92%- Ultra high performance low-temperature batteries with a discharge capacity of ≥ 95% at 02 ° C to 75 ° C;

　　(2) Low temperature lithium batteries have a wide operating temperature range, from -50 ° C to 60 ° C;

　　(3) Excellent low-temperature cycling performance, charged and discharged at 0.5C in an environment of -30 ℃, and maintained a capacity of over 85% after 300 cycles;

　　(4) High safety performance, certified by UL/CE/UN;

　　(5) Flexible in size, customizable in size and shape according to customer needs;

　　(6) Compared with traditional lithium polymer batteries, it has broken through the discharge temperature limit of -20 ℃ to 60 ℃.

　　(7) Capable of mass production and good consistency of batteries;

　　(8) Low temperature lithium batteries can generate large currents and maintain high capacity at -50 ℃;

　　(9) Low temperature lithium batteries can still maintain their excellent performance in a working environment of -50 ℃;

　　(10) Low temperature lithium batteries can be widely used in cold climates and military equipment.
