What are the characteristics of low-temperature lithium batteries?
Low temperature lithium batteries are lithium polymer lithium batteries and lithium iron phosphate batteries. What are the characteristics of ultra-low temperature lithium polymer lithium batteries and ultra-low temperature lithium iron phosphate batteries?
The ultra-low temperature lithium polymer lithium battery uses specialized rechargeable battery raw materials and independently innovates production and processing technology, which can effectively improve the charging characteristics of ultra-low temperature geographic environment rechargeable lithium batteries, reduce charging battery resistors, and achieve high-speed battery charging practical effects. Therefore, low-temperature lithium batteries have a long service life and extremely strong driving force- Charging the battery at ultra-low temperature of 30c, the charging capacity of the ultra-low temperature battery still exceeds 80%, which is one of the core technologies. Ultra low temperature lithium polymer lithium batteries have the following advantages.
1. Low temperature battery charging has high characteristics, with a minimum charging temperature of -50 ℃ and an efficiency of over 60%; In a geographical environment of -40 ℃, the charging capacity of the battery reaches 80%;
2. Wide coverage of working temperature- 50～50℃;
3. High quality ultra-low temperature respiratory system, rechargeable battery in -30c geographical environment, with a capacity maintained above 85% after 300 cycles of the system;
4. The security performance is higher than ul/ce/un;
5. The specifications and models are flexible and can be formulated based on customer satisfaction, specifications, models, and styling design;
Compared with traditional lithium polymer lithium batteries, the charging limit of the battery has been increased by -20c60c;
7. It has a large-scale production capacity and good consistency with rechargeable batteries;
At -50c, it will result in a large current flow and maintain a high capacity;
9. Maintain its high quality in a natural environment of -50c;
10. Commonly used in extremely cold temperatures and for defense machinery and equipment.
The ultra-low temperature lithium iron phosphate battery has the following characteristics:
1. Choose cumulative technology with low internal resistance;
2. Characteristics of high-quality ultra-low temperature work: the filling and discharging volume exceeds 60% of the original volume; The filling and discharging volume exceeds 70% of the original volume;
3. Wide coverage of working temperature- 40～55℃;
4. Rechargeable batteries can be charged on -20c batteries;
5. Select organic chemicals for phosphate iron lithium batteries with high safety performance and long cycle life.
