21700 Li-ion Battery 3.6V 5000mAh

The positioning of Sunpower New Energy is to align with the standard of Japan and South Korea’s world-class brands and export our products all over the world!

The Sunpower New Energy 21700 li-ion battery has good storage and cycle life performance under high-temperature conditions. The charging temperature is higher than 45℃ while the discharge temperature is higher than 60℃.

5000mAh 3.6V 6C high rate lithium-ion Battery 50SE is stable, safe, and reliable, can withstand all kinds of harsh environments, and can be specially developed for most users with particular specifications, special requirements of high-performance lithium battery and lithium battery pack.

1. The 21700 li-ion batterycan be stored in a high-temperature environment. The maximum operating temperature of the battery can be 85℃
2. The 21700 lithium ion cellshavesuperior performance, and the cell swelling rate is less than 2%, with no fire and no explosion at a high temperature of 120℃
3. Long endurance: 120℃ high temperature > 70 cycles, discharge efficiency is over 90%
4. Long battery cycle life: ≥600 cycle life
5. Discharge cut-off voltage is 2.5V and charging cut-off voltage is 4.2V
6. Maximum charge current is 10A (almost all other similar cells in Chinese market are only 5A) and continuous discharge current is 30A (almost all other similar cells in Chinese market are only 15A)
7. The 21700 li-ion batterymeets UL/CB/SGS/BIS/PSE/KC/MSDS/UN38.3 certification requirements and uses environmental protection material with high energy density

High-temperature battery technology:

The anode material is doped with metal elements by the calcination process, which improves the crystal structure stability of lithium cobalt oxide at high temperatures, reduces the oxidation capacity of the material, and inhibits the reaction between the electrode material and the electrolyte.

The 21700 lithium ion cells have superior anti-swelling and high safety performance, especially suitable for high temperature environments.
