Year-on-year growth of more than 28 times! The loading of lithium iron phosphate batteries may become a major trend in February.

The China Automobile Association disclosed monthly information on power batteries. China's lithium iron phosphate batteries loaded a total of 2.2 GWH in February, up 2826.0% from a year earlier. Industry experts pointed out that lithium iron phosphate counterattack ternary battery may become a trend.

According to the automobile industry information conference held by the China Association of Automobile Manufacturers on the afternoon of March 11, sales of new energy vehicles in China increased by 584.7% in February compared with the same period last year. At the same time, the China Electric vehicle Company, which replaced the lithium iron phosphate battery, began to show the obvious effect of cost reduction and profit improvement.

At present, the mainstream models with large sales and lithium iron phosphate batteries are Tesla Model 3 and BYD Han EV. Nearly 20,000 of the two models were sold throughout February, a sizeable figure.

Although both lithium iron phosphate battery and ternary lithium battery are lithium batteries, they have their own advantages and disadvantages. Since lithium iron phosphate batteries do not contain precious metal materials, the cost of raw materials can be compressed very cheaply. The ternary lithium battery is a lithium battery with lithium nickel cobalt manganate as cathode material and graphite as anode material, so the cost is much higher than that of lithium iron phosphate battery.

The liquid electrolyte of ternary lithium battery is flammable and explosive, which is easy to get out of control in the process of long-term use, and the growth of lithium dendrite is easy to pierce the diaphragm in the process of charge and discharge, causing the battery short circuit and causing safety risks. The lithium iron phosphate battery pack has the advantages of high temperature resistance, strong safety and stability and better cycle performance in practical use.

It is believed that the market will slowly give the answer to who is the real future battery trend between lithium iron phosphate and ternary lithium batteries.
