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!1, Light electric vehicles such as electric motorcycle, e-bike, e-scooter, golf car, folk lifter, floor cleaner 2, Power tool, electric garden tool, agricultural tool, special application tool ,Remote control plane, car, boat 3, Remote control plane, car, boat ,Solar energy, wind energy storage systems COMPARISON DATA AMONG VARIOUS LITHIUM BASE BATTERIESSafety CYCLE LIFEPOWER WEIGHT DENSITY LONG TERM COST Temperature RangeLiFePO4Excellent 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.
