Custom Lithium ion Battery Pack
20 Years Focus On Lithium Ion Battery Pack Customization
High temperature lithium ion battery refers to the battery that has good storage performance and cycle life performance under high temperature conditions. The charging temperature is higher than 45℃, while discharge temperature is higher than 60℃.
The high temperature lithium battery produced by LARGE is stable, safe and reliable, can withstand all kinds of harsh environment, and can be specially developed for the majority of users with special specifications, special requirements of high performance lithium battery and lithium battery pack.
1.It can be stored in high temperature environment. The maximum operating temperature of the battery can be 90℃.
2.The cell has superior anti-swelling performance, and the cell swelling rate is less than 3%.
3.Long battery cycle life: ≥500 cycle life
4.The products meet CE/ROHS/REACH/UL certification requirements.
Vehicle equipment (TPMS/ tire pressure, GPS, automobile data recorder), fire fighting equipment, oil and gas, monitoring equipment, open air lamps (road lights, emergency lights), solar charger, etc.
Battery Cell Selection + PCM & BMS + Structure Design + Chargers
Cell Selection and Cell Quality Detection
Design of shape and internal structure
Electrical performance design：protection function, accurate power display, host communication, certification, battery set-making, charging
Charger design：External or built-in charger
Mid-term overall re-evaluation
First sample
Basic electrical performance test, and test under different environmental conditions
High temperature performance is good. No swelling, no fire, no explosion at high temperature 125℃ ;
Long endurance: 125℃ high temperature > 70 cycles, discharge efficiency is over 90%;
High safety: in line with GB31241, UL1642, IEC62133 and other safety requirements;
The application conforms to RoSH, REACH environmental protection material with high energy density.
High Temperature Battery Technology
The anode material is doped with metal elements by calcination process, which improves the crystal structure stability of lithium cobalt oxide at high temperature, reduces the oxidation capacity of the material, and inhibits the reaction between the electrode material and the electrolyte.
The cell has superior anti-swelling performance and high safety performance, and is especially suitable for high temperature environment.
