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 -45~ 70 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. 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.

A New hope,Change in the future ! As more and more pollution,Warming seriously,Earth Close to Unfit for human Living. Now, we must begin to use high-tech The energy to change the day of the disaster. LiFePO4 Battery Is a new energy,It will not cause pollution,It does not produce an explosion,Long life,Structural stability,Cheaper! 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. LiFePO4 is an intrinsically safer cathode material than LiCoO2 since exothermic reactions cannot occur in batteries based on this material: LiFePO4 cells do not incinerate or explode under extreme conditions. In addition, LiFePO4 cells have a higher discharge current, are not toxic and have a much higher cycle life than LiCoO2 cells.
