High and low temperature lithium battery is a serial of special battery aim to improve the  temperature defects inherent in the performance of chemical power by innovative design concept, using advanced formula system and materials, strict manufacturing processes and methods. 

Performance characteristics
1, High temperature performance
shelve the battery at 70 °C  with 24h and volume change rate is less than 0.5%
shelve the battery at 85 °C 48 hours with full power, the battery has no tympanities, no fire, no explosion.

2, Low temperature battery performance is excellent
Discharging on Low temperature -20°C with 0.2C, the battery capacity is more than98% initial capacity
Discharging on Low temperature -40°C battery capacity is more than 90% rated capacity.
the high rate battery with Special technology can increase the discharging current for 0.2C up to 1.0C on low temperature -40 degree
When at -50 degrees, the full discharged capacity can be more than 50% of the rated capacity
3, the battery cycle life is long, low power consumption, high safety performance
Battery cycle life more than 400 times, generally up to 1200 times.
