Safety performance of lithium phosphate battery
First of all, reduce the cost. During the production of vehicles, the cost of batteries is high, accounting for about 50% of the cost of vehicles. In addition, subsidies and other things are on the decline. From the price advantage, the price of vehicles has little advantage over fuel vehicles. However, the cost of lithium phosphate battery is far lower than that of ternary lithium battery. For the production of vehicles, the use of lithium phosphate battery can save the production cost of vehicles.
Then, in the second aspect, improve the stability of the battery and increase the safety performance of the battery. For the lithium iron phosphate battery, the performance is more stable than the ternary lithium battery, and the advantage is more obvious than the ternary lithium battery. The spontaneous combustion temperature of the lithium iron phosphate battery is 800 ℃ and that of the ternary lithium battery is 200 ℃. Obviously, it is difficult for vehicles equipped with LiFePO4 batteries to spontaneously ignite. From this point of view, the safety performance of vehicles is greatly improved.
In the third aspect, replacing the lithium phosphate battery can also prepare for the production capacity of the vehicle. In the production of the above lithium iron phosphate battery, the material of the internal motor is easier to produce than that of the ternary lithium battery. In addition, with the improvement of the industrial chain of lithium phosphate battery, there is no need to worry about the problem of energy production. Generally speaking, the main purpose of replacing lithium phosphate battery is to reduce the cost of vehicles and improve the safety performance of vehicle batteries. In the fierce competition of electric vehicle market, who can first reduce the cost of power battery, and then meet people's demands for long driving range, high safety and long service life. It is bound to get a bigger share of the market.
