LiFePO4 battery has hybrid characters: as safe as lead-acid battery and as powerful as lithium ion cells. The advantages of large format Li-ion (polymer) batteries containing lithium iron phosphate (LiFePO4) are listed as below: 1. fast charging: 2. Large overcharge tolerance and safer performance 3. Self balance 4. Simplifying battery management system (BMS) and battery charger 5. Longer cycle life In comparison with LiCoO2 battery which has a cycle life of 400 cycles, LiFePO4 battery extends its cycle life up to 2000 cycles. 6. High temperature performance It is detrimental to have a LiCoO2 battery working at elevated temperature, such as 60C. However, a LiFePO4 battery runs better at elevated temperature, offering 10% more capacity, due to higher lithium ionic conductivity.
