The application demand for lithium nickel manganese oxide cathode material (LNMO) is growing, and high quality is the main direction of industry development.

Lithium nickel manganese oxide (LNMO) refers to an inorganic metal composite oxide with a spinel structure and a binary layered structure compound. Among them, spinel type lithium nickel manganese oxide is widely used, and its chemical formula is LiNi0.5Mn1.5O4. Lithium nickel manganese oxide has the advantages of good conductivity, high energy density, good rate performance, low production cost, good safety, and long service life. It is often used as anode material for lithium-ion batteries and is widely used in consumer electronics, automobile manufacturing and other fields.

There are five methods for preparing lithium nickel manganate cathode materials, including sol-gel method, high-temperature solid phase method, coprecipitation method, hydrothermal method, and solvothermal method. The high-temperature solid-phase method is a traditional preparation method for lithium nickel manganate cathode materials. It has the advantages of high technological maturity and controllable crystal structure type, but the electrochemical performance of the finished product is poor; the solvothermal method is a method derived from the hydrothermal method. , which uses a metal salt solution as the raw material, adds a precipitant, and then undergoes a high-temperature reaction to obtain the product. This method has the advantages of good finished product quality and simple preparation process, and is the mainstream preparation method for lithium nickel manganese oxide cathode materials.

According to the “2023-2028 China Lithium Nickel Manganese Oxide Cathode Material (LNMO) Industry Market In-depth Research and Development Prospects Forecast Report》 shows that lithium nickel manganese oxide cathode material is mainly used in the production of lithium-ion batteries, with consumer electronics, automobile manufacturing, etc. as its end markets. Benefiting from national policy support and accelerated economic development, the prosperity of my country’s new energy vehicle industry has improved, driving further growth in lithium-ion battery production. According to statistics from the Ministry of Industry and Information Technology, my country’s lithium-ion battery production exceeded 400GWh in the first half of 2023, a year-on-year increase of more than 43%. Benefiting from the rapid development of downstream industries, my country’s demand for lithium nickel manganese oxide cathode material applications is increasingly strong.

Although the development prospects of the lithium nickel manganese oxide cathode material industry continue to improve, it still faces many problems that need to be solved. On the one hand, when the material voltage platform is too high, lithium nickel manganese oxide is prone to decomposition of the electrolyte system and weakened corrosion resistance; on the other hand, in high temperature environments, lithium nickel manganate is prone to oxygen deficiency problems, and its cycle The life span and discharge specific capacity will be reduced. At present, Chinese companies have begun to use surface coating, ion doping and other modification methods to solve the performance problems of lithium nickel manganese oxide cathode materials. In the future, the industry will gradually develop in the direction of high quality.

my country’s lithium nickel manganese oxide cathode material industry has a high degree of concentration. The main production companies include Kashgar Ande, Dangsheng Technology, Rongbai Technology, Qingtao Energy, etc. Rongbai Technology has independent research and development capabilities for spinel-type lithium nickel manganese oxide, lithium-rich manganese-based and other battery materials, and is a representative enterprise of lithium nickel manganese oxide cathode materials in my country.

Industry analysts said that lithium nickel manganese oxide cathode material has excellent comprehensive properties and is expected to become a mainstream battery material in the future. However, at present, my country’s industry Development still faces many problems that need to be solved urgently. It is expected that in the future, as local companies continue to exert their efforts, the technical level of my country’s lithium nickel manganese oxide cathode materials will be further improved.
