Is the development of lithium iron phosphate batteries related to the future of electric vehicles?

In recent years, the rapid development of electric vehicles has driven the development of power lithium iron phosphate batteries. As the power source of electric vehicles, the performance of the battery is not only related to the length of the vehicle's driving range, but also related to the safety and reliability of the product. It can be said that the development of power lithium batteries determines the future of pure electric vehicles. In the author's view, in order to promote the development of the new energy vehicle industry, standardizing the use of power lithium-ion batteries is the key. Regarding whether it is a fuel vehicle or a new energy vehicle, safety has always been the vital door for the development of the automobile industry, and is the critical foundation and guarantee for the development of the entire automobile industry. The sales of new energy vehicles have continued to rise for many years, and safety issues seem to be particularly important. The safety of electric vehicles depends critically on the safety of power lithium iron phosphate batteries. Like a gasoline tank, the lithium iron phosphate battery pack is a component containing high-energy substances. The electrolyte in lithium batteries is formulated with organic solvents, and its flammability is no less than gasoline. The oxidizer of the positive electrode and the reducing agent of the negative electrode are separated by a micron-thick separator, and internal short circuit generates heat; during charging and discharging, the internal resistance of the battery also generates heat. When a certain temperature is reached, the oxidant on the positive electrode can chemically react with the electrolyte. A large amount of chemical reaction heat will cause thermal runaway, and a large amount of gas will appear, which will cause the air pressure to rise, the battery to break, and then the vehicle will burn and explode. If the high-safety lithium iron phosphate battery is used in the extended-range electric vehicle, not only the safety of the vehicle can be improved, but the specific energy and specific power are fully sufficient, and the service life is long. In addition, my country is rich in lithium resources, and there is no problem of restricted cobalt and nickel resources. my country’s policy on the energy density improvement of the lithium battery industry has been clear. The 'Made in my country 2025' promulgated by the Ministry of Industry and Information Technology states that by 2025 and 2030, the energy density of my country’s power lithium iron phosphate batteries must reach 400Wh/kg and 500Wh/kg, respectively. , The subsidy is directly linked to energy density and the threshold is continuously raised. It is expected that the market growth rate will reach about 50% in the next three years, and the market share will continue to gather in advantageous companies. Therefore, my country should focus on lithium iron phosphate batteries to support the marketization of extended-range electric vehicles. It can effectively eliminate the five major concerns of pure electric vehicles such as mileage, safety, price, charging, and follow-up batteries.
