Lithium Iron Phosphate (LiFePO4):Lithium iron phosphate (LiFePO4) is a type of lithium-ion battery, which is a rechargeable battery that uses LiCoO2 as the cathode material. The main advantages of using LiFePO4 are that it has a higher discharge voltage than LiCoO2 (3.2 V vs. 2.8 V), and it is more stable and safer to use. LiFePO4 also has a higher energy density than LiCoO2, meaning that it can store more energy per unit weight.
