Of course, the technical level of the battery manufacturer's own R&D and manufacturing engineers is also very related to the level of production and manufacturing equipment.
40 60 Special Low Temperature Lithium Battery Products".
As a professional low-temperature battery manufacturer, after years of research and development and practical testing and application with partners, Juda has a low-temperature battery system that can be charged and discharged with high performance in a low-temperature environment.
1. Charge-discharge performance of low-temperature batteries
There are two major systems: low-temperature lithium battery and low-temperature lithium iron phosphate battery, and their respective charging and discharging properties are as follows:
1) Low-temperature polymer lithium battery
Low-temperature polymer lithium battery is a low-temperature special lithium battery after years of R&D, manufacturing and practice improvement, after continuous improvement of raw materials and equipment technology, the current low-temperature battery has the following performance:
1. High low-temperature discharge performance, the lowest is -50 to 02C discharge, efficiency more than 60%;In the -40 environment, 02C discharge, discharge capacity up to 80%;
2. Wide operating temperature range: -50°C to 50°C and -40°C to 60°C
3. Excellent low-temperature cycling performance, 0 in -30 environment5C charge and discharge, the capacity is kept above 85% after 300 cycles;
4. High safety performance, UL CE UN certification;
5. The size is flexible, and it can be customized in size and shape according to customer needs
6. Compared with traditional lithium polymer batteries, it breaks through the discharge temperature limit of -20 60.
7. It has the ability of mass production and good consistency of the battery
8. It can generate large current and maintain large capacity at -50
2) Low-temperature lithium iron phosphate battery
1. Excellent charging and discharging performance of low-temperature lithium iron phosphate batteries:
Juda low temperature lithium iron phosphate batteries are stored at -50 -40 -30 -20 -10 0 for 2 hours and then 05C discharge to 15V, -50 0 Low Temperature 0The 5C discharge efficiency is %.
Discharge performance of low-temperature lithium iron phosphate cells.
It is discharged at a current of 1C magnification in different low-temperature environments. Respectively at -40 -30 -20 -10 0, we can see that the discharge efficiency is %, respectively, and the overall discharge efficiency is maintained high.
2. Adopt lamination process manufacturing technology, low internal resistance;
3. Wide operating temperature range, -40 to 50;
4. It can be charged at -20;
5. The size is flexible, and the size and shape of the battery can be designed separately according to customer needs.
6. The low-temperature lithium iron phosphate battery is 0After 300 cycles, there is still more than 90% capacity retention rate of 2C discharge.
Second, the production and manufacturing strength of low-temperature battery manufacturers
Juda lithium battery: on-demand customization of low-temperature lithium batteries, explosion-proof lithium batteries, power energy storage lithium batteries, 18650 lithium batteries and intelligent lithium batteries, providing a full set of lithium battery solutions and products such as "cell customization + BMS management + structural design + charger", batteries are widely used in national defense science and industry, medical equipment, emergency fire protection, security communications, rail transit, exploration and mapping, photovoltaic energy storage, instrumentation and other fields, is a well-known lithium battery custom manufacturer in the industry.
Juda low-temperature lithium battery uses proprietary battery raw material formula and innovative manufacturing technology, which can effectively improve the discharge performance of the battery in a low-temperature environment, reduce the internal resistance of the battery, and achieve the effect of high-speed dischargeTherefore, low-temperature lithium batteries have a longer life and stronger power. At a low temperature of -40 at a temperature of 02C discharge, the huge low-temperature battery discharge capacity is still more than 80%.
