The ternary lithium-ion battery refers to the lithium-ion battery using the nickel cobalt manganate lithium potassium ternary cathode material. Compared with the iron phosphate lithium-ion battery introduced earlier, it has high energy density, appropriate price, and more excellent comprehensive performance, becoming the battery type used by most new energy vehicles at present.

The shortcomings of the seemingly perfect ternary lithium-ion battery have also been questioned. The biggest disadvantage of ternary lithium-ion battery is that it will decompose at about 200 ℃. Under the use of high temperature, the electrolyte will burn rapidly, and the new battery will have the risk of spontaneous combustion or explosion. With the development of technology, many manufacturers have developed excellent battery management systems. The safety problems have been improved, and the outstanding performance has won the recognition of major automobile manufacturers. The ternary lithium ion battery will become the mainstream battery of new energy vehicles in the future.

Lithium iron phosphate electrode material is the safest cathode material for lithium-ion batteries at present. In addition, its cycle life has reached more than 2000 times, and the standard charging (5-hour rate) can reach 2000 cycles. In addition, due to the mature industry, the price and technology threshold have decreased, which makes many manufacturers use lithium iron phosphate batteries for various reasons. It can be said that the rise of new energy vehicles has an inseparable relationship with the lithium iron phosphate battery pack.

Lithium ion batteries are made of lithium iron phosphate battery packs, which have the advantages of high energy density, small size, light weight, safety, environmental protection, long service life, high temperature performance, etc., and are widely used in new energy vehicles.
