Who is the future of electric vehicles? Lithium iron phosphate battery or ternary lithium battery?

　　In the early days, most electric vehicles used lithium iron phosphate batteries. However, later on, with the subsidy policy being linked to battery energy density, coupled with user requirements for pure electric driving range and the development of ternary lithium battery skills, most new energy vehicle models on the market are now equipped with ternary lithium batteries.

　　In an era where pure electric range and battery energy density have become the two core goals affecting subsidies, blindly pursuing subsidies has actually caused many products with immature skills to sacrifice safety for higher energy density. Various incidents of fires and recalls are paying for these chaos.

　　However, the development direction of electric shopping malls is ultimately good. With the decline of subsidy policies and the gradual weakening of policy dividends, the industry's pursuit of pure electric range and battery energy density is no longer as enthusiastic as before. Lithium iron phosphate is once again being chosen by more car companies for its higher safety, higher economy, and better cycle life.

　　Although subsidies have declined, for consumers, the key is still whether lithium iron phosphate batteries can receive subsidies? According to the new national subsidy policy, the vehicle's range must be at least 300km or more, and the energy density of the battery system should not be less than 125Wh/kg.

　　In recent years, with the advancement of skills, the energy density of lithium iron phosphate batteries has been improved to a certain extent. The energy density of lithium iron phosphate battery cells produced by battery manufacturers such as BYD, Lishen, and Guoxuan can all reach 190Wh/kg, and is expected to reach 220Wh/kg. BYD's blade battery has an energy density of 140Wh/kg and a range of 605km under NEDC standards.
