| COMPARISON DATA AMONG VARIOUS LITHIUM base BATTERIES | |||||
| Cells | Safety | CYCLE LIFE | POWER WEIGHT DENSITY | LONG TERM COST | Temperature Range |
| 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 Most economic | Excellent (can be discharged at 70~ -45 Centigrade) |
| 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 | Perfect | High Cost | 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 | Decayed extremely fast over 55~ -20 Centigrade |
| 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 | Perfect | High Cost | Decayed extremely fast over 55~ -20 Centigrade |
 | LiFePO4 material is by far the safest, most long cycle life, no pollution to the environment of new energy materials ! LiFePO4 will become the preferred battery technology for traction purposes and other situations in which high discharge characteristics and cycle life are important. (LiFePO4) batteries are based on the original lithium-ion chemistry, but LiFePO4 is used as the cathode material instead of lithium cobalt dioxide (LiCoO2). The latter is found in the most commonly used batteries in laptops, cell phones, MP3 players, etc. |
