The materials used in two types of lithium-ion batteries are different. Ternary lithium-ion batteries refer to lithium-ion batteries with nickel cobalt manganese ternary cathode materials as the positive electrode material; The Lithium iron phosphate battery, as its name implies, uses Lithium iron phosphate as the cathode material.

　　In terms of energy density ratio, the ternary lithium iron battery has more advantages than the Lithium iron phosphate battery, which is thinner and lighter. In terms of cycle life, the Lithium iron phosphate battery will be better than the ternary lithium battery, which has a cycle life of more than 2000 times. However, the Lithium iron phosphate battery has a simple and stable battery structure and higher safety performance.

　　The Lithium iron phosphate battery can work normally at 80 ℃, and has good high-temperature performance. The use range of the ternary lithium battery is 60 ℃. At the same time, the working voltage is also the main difference between the two batteries. The working voltage of the ternary lithium battery is 3.6v, while that of the Lithium iron phosphate battery is 3.2v.
