Development direction of 1.5v Alkaline battery cathode material technology

　　Development direction of 1.5v Alkaline battery cathode material technology. As lithium battery technology improves and the lithium battery market matures, the application fields of different cathode materials are gradually divided, that is, lithium-ion batteries have different performance requirements for various cathode materials. Therefore, the mainstream synthesis technologies and processes of cathode materials have also experienced different development paths.

　　Development direction of 1.5v Alkaline battery cathode material technology

　　In order for 1.5v Alkaline battery cathode materials to exert the best performance in the full battery, it is necessary to further optimize the crystal structure, particle structure and morphology, particle surface chemistry, material packing density and compaction density of the material on the premise of optimizing the material composition. physical and chemical properties, and it is also necessary to strictly prevent the introduction of trace metal impurities during the process.

　　The focus of research and development of cathode materials for lithium-ion batteries: high safety, low cost and high performance cathode materials.

　　1) Progress in research and development of high-nickel cathode (NCM or NCA) materials that balance high energy density and safety: high-nickel and low-cobalt are the development trend. The current cobalt usage in Tesla power batteries is less than 3% and will drop to 0% in the future. In early June 2018, Panasonic announced that it was developing cobalt-free electric vehicle batteries;

　　2) Research and application research on olivine structure LMnPO4, LMFP or hybrid materials;

　　3) Study on the long-term stability of lithium-rich lithium-rich manganese-based materials;

　　4) Research on the safety performance evaluation of existing cathode materials after recycling - the inner revelation of spontaneous combustion phenomenon;

　　5) Research on composite or hybrid cathode materials that improve safety, reduce costs and maintain high overall performance.

　　Development Trend of 1.5v Alkaline battery Cathode Materials

　　The development trend of high energy density 1.5v Alkaline battery cathode materials. From the perspective of product application, lithium-ion batteries have covered mobile communications, portable computers, digital equipment, power tools, electric bicycles, electric vehicles, energy storage base stations, and special equipment. and many other application fields. Around different usage characteristics, corresponding cathode material systems have basically been formed in various application fields to match them.

　　High voltage and high capacity are the eternal pursuit of lithium batteries. At present, ternary materials are not mature enough, and have formed a transitional situation. Many passenger cars have already used ternary materials. The first one to try it is Tesla, which has led to the market's pursuit of ternary materials, while commercial vehicles and Due to safety considerations, construction vehicles currently do not use ternary vehicles, but current logistics vehicles are also trying to use ternary vehicles.

　　Lithium battery cathode materials will tend to be stable in the future, but with the rapid development of power energy, the main market growth depends on the growth rate of electric vehicles in the next five years.
