01 Different properties, lithium iron phosphate battery: a lithium ion battery using lithium iron phosphate as the positive electrode material; Ternary lithium battery: The positive electrode material of lithium battery is lithium nickel cobalt manganate or nickel. Cobalt-aluminum acid lithium ternary cathode material.
With the dvigorous development of new energy vehicle industry, domestic battery industry is developing rapidly. As a core element of electric vehicles, the configuration of power batteries plays a vital role. Currently, the battery types selected by various automobile manufacturers on the market are roughly divided into two types, one is ternary lithium battery and the other is lithium iron phosphate battery. The differences between the two are as follows.
1. Different properties:
1. Lithium iron phosphate battery: A lithium-ion battery using lithium iron phosphate as the positive electrode material.
2. Ternary lithium battery: The cathode material of lithium battery is lithium-nickel-cobalt or lithium-nickel-cobalt-aluminate ternary cathode material.
2. The main materials are different:
1. Lithium batteryer phosphate: The cathode materials of lithium ion battery mainly include lithium cobalt acid, lithium manganese acid and lithium nickel acid. , ternary materials, Lithium iron phosphate, etc. Lithium-cobalt oxide is the cathode material of most lithium-ion batteries.
2. Ternary lithium battery: The ternary composite cathode material is composed of nickel salt, cobalt salt and manganese salt as raw materials. The proportion of nickel, cobalt and manganese can be adjusted according to actual needs. .
3. Different applications:
1. Lithium iron phosphate battery: large electric vehicles: buses, electric cars, tourist buses and light electric vehicles: electric bicycles; , golf carts, small flat battery carts, forklifts, cleaning vehicles, electric wheelchairs, etc. power tools: electric drills, trochainsaws, lawn mowers, etc.
2. Ternary lithium battery: widely used in mobile and wireless electronic equipment, power tools, hybrid and electric vehicles and other fields.

100~120Wh/kg. Energy density is the ratio of battery energy to mass, which is slightly lower than other lithium-ion batteries. The specific energy of lithium iron phosphate battery is about 120 ~ 140 wh/kg, and the spatial density is about 200 ~ 250 wh/l.
1. Lithium iron phosphate is a lithium-ion battery electrode material with the chemical formula LiFePO4 (LFP for short). It is mainly used in various lithium-ion batteries. Since the Japanese NTT first revealed the olivine structure lithium battery cathode material of AyMPO4 (A is an alkali metal,M is CoFe: LiFeCoPO4) in 1996, Texas in the United States in 1997The research group of John.B.Goodenough and other researchers at the University of Austin also subsequently reported the reversible transfer of lithium to and out of LiFePO4.
2. Compared with traditional lithium-ion secondary battery cathode materials, LiMn2O4 spinel structure and LiCoO2 layered structure, LiMPO4 has wider raw material sources, is cheaper and has no environmental pollution.
