LiFePO4 |
The world's most secure battery, no explosion, no pollution, long life |
Excellent Cycle life can be as long as over 2,000 cycle, best among all the listed groups. |
Acceptable | Excellent |
Excellent (can be discharged at -45~ 70 Centigrade) |
Most economic | |||||
LiCoO2 |
LiCoO2 is expensive, the actual capacity than its theoretical capacity of only (274mAh g-1) about 50%, lower utilization of cobalt; LiCoO2 cycle life has reached 500 |
Acceptable Cycle life only up to 300~500 cycle. Not good for high C-rate discharge. |
Good | High |
Decayed beyond 55 ~ -20 Centigrade |
LiMn2O4 |
Have to handle with care, or it might explode or catch fire under collision or over-charged. |
Unacceptable Cycle life only up to1 500~800 cycle, depending on the discharge C-rate. |
Acceptable | Acceptable | High |
Li(NiCo)O2 |
Very unstable, must handle with extremely care, it might explode or catch fire under collision, over-charged, short circuit or when heat build-up. |
Acceptable Cycle life can be 300~500 cycle. Not good for high C-rate discharge. |
Good | High |
Decayed extremely fast over 55~ -20 Centigrade |
