Abstract

Lithium-ion batteries have high energy density, power density and long cycle life, and are widely used in the new energy vehicle industry and energy storage power stations, and their industrial development and technological progress are closely related to national policies and industry needs. To this end, this paper reviews the development status of the power battery industry, combs the policy guidance of the power battery industry at home and abroad, summarizes the current development status of the positive electrode materials, negative electrode materials, diaphragm materials and electrolyte materials for power batteries, and looks forward to the development trend of power battery raw materials.
