What is the LiFePO4 Battery ?
LiFePO4 is an intrinsically safer cathode material than LiCoO2 since exothermic reactions can not 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.

 
Battery system design
LiFePO4 cells can be purchased from various suppliers with diverse characteristic and price levels. The art of engineering a full-sized EV battery system is to select the proper cells, design the battery pack and battery management system (BMS) -taking geometric, thermal and electric constraints into account- and select the appropriate charger.
The above characteristics make LiFePO4 the ideal chemistry for electric vehicle applications.
LIFEPO4 Battery Wide Application Fields!
Light electric vehicles such as electric motorcycle, e-bike, e-scooter, golf car, folk lifter, floor cleaner
Power tool, electric garden tool, agricultural tool, special application tool ,Remote control plane, car, boat
Remote control plane, car, boat ,Solar energy, wind energy storage systems
   

COMPARISON DATA AMONG VARIOUS LITHIUM BASE BATTERIES
  Safety CYCLE LIFE POWER WEIGHT DENSITY LONG TERM COST Temperature Range
LiFePO4 Excellent
Safest and most envirofriendly among all the listed groups
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 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 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 to100~800 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
