my country's "Energy-saving and New Energy Automobile Industry Development Plan" puts forward "The overall goal of my country's new energy vehicle development is: by 2020, the cumulative production and sales of new energy vehicles will reach 5 million, and the scale of my country's energy-saving and new energy automobile industry ranks among the world. Forefront". Lithium iron phosphate batteries are widely used in passenger cars, buses, logistics vehicles, low-speed electric vehicles, etc. due to their safety and low cost advantages. Although, in the current new energy passenger vehicle field, it is subject to the state's subsidy policy for new energy vehicles. Influence, relying on the advantages of energy density, ternary batteries occupy a dominant position, but lithium iron phosphate batteries still occupy an irreplaceable advantage in fields such as passenger cars and logistics vehicles. In the field of passenger cars, lithium iron phosphate batteries accounted for approximately 76%, 81%, 78% in the 5th, 6th, and 7th batches of the "Catalogue of Recommended Models for the Promotion and Application of New Energy Vehicles" (hereinafter referred to as the "Catalog") in 2018. %, still maintain the mainstream. In the field of special vehicles, lithium iron phosphate batteries accounted for approximately 30%, 32%, and 40% of the 5th, 6th, and 7th batches of the Catalog in 2018, and the application proportion is gradually increasing.
Yang Yusheng, academician of the Chinese Academy of Engineering, believes that the use of lithium iron phosphate batteries in the extended-range electric vehicle market can not only improve the safety of vehicles, but also support the marketization of extended-range electric vehicles, eliminating the mileage, safety, price, and cost of pure electric vehicles. Anxiety about charging, follow-up battery problems, etc. During the period from 2007 to 2013, many car companies launched projects for extended-range pure electric vehicles.
