Abstract:

With the development of the new application fields, the lithium ion battery industry has shown steady and rapid growth in recent years, and its cathode materials have ushered in unprecedented development opportunities. China has a unique advantage in the development and industrialization of positive materials for lithium-ion batteries. It has a perfect industrial chain and a good momentum for sustainable development. More and more cathode species and product types appear on the market. In this paper, the status quo of cathode material standards for lithium ion batteries in China is introduced, the requirements of key technical indicators for different kinds of cathode materials are compared and analyzed, the reasons for the differences of technical indicators are explained, and the shortcomings of individual standards are pointed out. At last, some suggestions about future standardization work for LIB cathode materials are put forward.

Key words: lithium ion battery, cathode materials, standards, technical indicators, industrialization
