In recent years, China's new energy vehicles have developed rapidly, driving the strong demand for power lithium batteries. The positive electrode material is the most important raw material in the lithium battery. In the current market, the positive electrode material of the power battery has three characteristics: system diversification, individual demand, and market change.
The first feature is the diversification of the system. At present, the positive electrode materials for power batteries on the market mainly include lithium manganate, lithium iron phosphate, lithium nickel cobalt manganese oxide and nickel-cobalt binary materials. Different material systems have their own characteristics, and they have their own application fields and market demands.
Lithium manganate system has the characteristics of low cost, high platform and excellent safety performance, and it has a large share in the fields of replacing lead-acid batteries and low-speed logistics vehicles. However, this material has a low volumetric specific capacity and a high temperature cycle, which makes it limited in applications such as commercial vehicles and logistics vehicles.
Lithium iron phosphate battery is currently used in the Chinese market. The high safety and cycle stability of this material make it a position in commercial vehicles, special vehicles and other applications.
Lithium nickel cobalt manganese oxide and nickel-cobalt binary materials have increased in the power market in recent years. The global Tesla electric car has opened a new era of ternary electric vehicles. Based on the constant pursuit of volumetric energy, more and more electric logistics vehicles and passenger cars choose to use such materials.
