Developments in the production technology of cathode materials for lithium-ion batteries
2022/12/01
At the end of the last century, from the perspective of processing performance and battery performance of lithium-ion battery cathode materials, a research team from Tsinghua University proposed the technique of controlled crystallization to prepare high-density spherical precursors, combined with the subsequent solid-phase sintering process, to propose an industrial technology for the preparation of lithium-containing electrode materials. In particular, the controlled crystallisation method for the preparation of precursors allows for the regulation and optimisation of the material properties at four levels: cell structure, primary particle composition and morphology, secondary particle size and morphology, and particle surface chemistry. The materials produced using this technology are characterised by easy control of particle size and morphology, good homogeneity, batch consistency and stability, and can meet both the electrochemical and processing performance requirements of the battery. The material is particularly suitable for high specific energy batteries due to its high bulk density. The technology process is applicable to a wide range of cathode materials and is suitable for mass production. Over time, it has gradually proven to be a technical process for the production of cathode materials for lithium-ion batteries and has been generally accepted and recognised by the industry today. It is also one of the important contributions made by our scientists to the international lithium-ion battery industry.
