What is the energy density of lithium iron phosphate batteries?

At present, my country's automotive power lithium-ion battery technology route chooses the same lithium iron phosphate route as the United States. There is no doubt that lithium iron phosphate batteries have many advantages: high stability and relatively cheap price, but its energy density (the energy density is greater, and the mileage problem can be better dealt with) is very limited. It is known that the energy density of lithium iron phosphate battery cells can reach 157Wh/kg, but the energy density of single cells is reduced to 100Wh/kg after grouping. At present, the capacity density of lithium iron phosphate batteries is generally around 150Wh/kg, even if it is done better, it is still around 160Wh/kg. Compared with the 200Wh/kg energy density of ternary batteries, there is a big gap. The 32131 high-energy-density cylindrical lithium iron phosphate battery to be processed has a single energy density of 180Wh/kg. Passenger cars using this battery can have a cruising range of more than 300km. With the development and use of a variety of new materials and new technologies, Guoxuan Hi-Tech plans to increase the lithium iron phosphate monomer cell to a maximum of 200Wh/kg in 2019. Guoxuan Hi-Tech revealed to investors on the interactive platform that BAIC New Energy’s EC180 and EC220 models will use the company’s high-energy-density lithium iron phosphate batteries this year. At present, the energy density of the company's high-energy lithium iron phosphate battery is close to the level of ternary 333. At the same time, it is clearly better than the ternary battery in terms of cycle life and cost control. Continuously improving. The battery using lithium iron phosphate batteries has reached or even exceeded the performance of the ternary battery in all aspects of the system and the vehicle, making the iron-lithium battery in the category of new energy passenger cars to achieve a situation of keeping pace with the ternary battery. In terms of other batteries, Guoxuan Hi-Tech once stated in a survey conducted by the Power Lithium-ion Battery Use Branch of the my country Chemical and Physical Power Supply Industry Association and the Battery my country Network that the company has undertaken the 300wh/kg high-energy density major technology project of the Ministry of Science and Technology. The progress is smooth, and the energy density of the soft-pack batteries independently developed by the company has reached 302Wh/kg. The company will continue to focus on this major science and technology project, and plans to promote the industrialization of related products this year.
