Which one is more suitable for power lithium-ion battery, acid iron lithium battery or ternary lithium battery?

Is it better to choose lithium iron phosphate batteries or ternary lithium batteries for power lithium-ion batteries? At present, domestic power lithium-ion batteries are mainly divided into two factions. According to the different cathode materials, they are divided into lithium iron phosphate and ternary materials. The author thinks that in the future, more power lithium-ion batteries will still choose lithium iron phosphate batteries. ①In terms of technical routes, more and more range-extended electric vehicles are beginning to use lithium iron phosphate batteries, which can not only improve vehicle safety, but also reduce the cost of vehicle manufacturing, and help extend range-extended electric vehicles to expand in the new energy vehicle market. Share. For example, the lowest market prices for power lithium-ion batteries with a battery capacity of 25Ah and a voltage of 48V, lithium iron phosphate batteries and ternary lithium batteries are generally RMB 1,020 and RMB 1,210. ②In the energy storage market, thanks to some power lithium-ion battery companies starting to deploy energy storage business, the market demand for lithium iron phosphate began to expand. According to the energy storage report of GTMResearch, an international market research organization, the decline in lithium battery prices slowed down in 2018, but the application of grid-side energy storage projects in my country has continued to increase the amount of lithium iron phosphate batteries. ③On the other hand, with the continuous improvement of technology, the energy density of some lithium iron phosphate batteries has reached the level of ternary NCM523 (the mainstream NCM523 battery energy density is 160-200Wh/kg), which has basically reached the highest subsidy requirement. And compared to ternary lithium batteries, lithium iron phosphate batteries have more advantages in terms of stability. ④Finally, the subsidy has fallen sharply. The reason why lithium iron phosphate has low risk in the supply and price of raw materials is that no precious metals such as cobalt are used, which will help battery processing companies to reduce cost pressures to a certain extent. .
