Features:
Feature of Lithium battery -safe
Øthe chemical structure of lifepo4 is very stable
Feature of Lithium battery –long lifespan
ØOver 2000cycles with capacity staying at 80%
Feature of Lithium battery –High energy density
ØEnergy density: 130 Wh/kg
ØWeight:1/3 of lead acid,2/3 of Ni-MH
ØVolume:2/3 of lead acid
Feature of Lithium battery –Wide Temp range
Ø Working Temp range:-20°C-+70°C
Ø Perform good in high Temp:reach 350°C-500°C in peak, about 200°C for LiCoO2 and LiMn2O4
Feature of Lithium battery –Fast charge
Ø 1C standard charge and discharge,above 93% of the capacity during 3.3~3.0V platform
Ø Steady charge and discharge platform,can reach high current power charge and discharge
Ø Good at high discharge rate, above 96% charge and discharge efficiency by 10C
Feature of Lithium battery –less self-discharge
self-discharge<5%(month), while the monthly self discharge of sealed lead acid battery is 10%.
Feature of Lithium battery –environment friendly
No heavy metal, no pollution, green and environment friendly, while Lead-acid Battery is with heavy metals such as Lead, Antimony, causing serious pollution of environment. It is easy to leak when using and maintenance and will lead to corrosion of equipment and accident when the internal Sulfuric Acid leaks.
