As a cathode material for lithium-ion batteries, lithium manganate industry has great potential for development

Lithium manganate mainly includes spinel-type lithium manganate and layered structure lithium manganate. Its chemical formula is LiMn2O4 and its appearance is black-gray powder. Lithium manganate is made from manganese dioxide and lithium carbonate as raw materials, with corresponding additives, and through steps such as mixing, sintering, and post-processing. Compared with lithium cobalt oxide, lithium manganate has the advantages of low energy consumption, sufficient output, low production cost, and good safety. It is one of the more promising lithium ion cathode materials.

Lithium manganate production methods include high-temperature solid-phase reaction method, Pechini method, sol-gel method, co-precipitation method, and silica gel template method. At present, the high-temperature solid-state reaction method is a commonly used method in the lithium manganate industry. It selects solid compounds such as lithium, manganese oxide or carbonate, and reacts them to generate lithium manganate materials through high-temperature burning. This method has a simple and easy process. operation, but the production cycle is long and the mixing uniformity of the reactants is poor. The silica gel template method uses commercial silica gel as a hard template to synthesize nanoscale lithium manganate powder. The powder particle size distribution is uniform, which improves the electrochemical performance of lithium manganate. This method has good application prospects.

According to the “2022-2027 China Lithium Manganese Oxide Product Market Analysis Feasibility Research Report released by the Industrial Research Center, manganic acid Lithium is mainly used as cathode material in the manufacture of lithium-ion batteries for mobile phones, laptops and other portable electronic devices, and can also be blended into ternary materials. Compared with traditional battery technology, lithium-ion batteries are small, charge quickly, and can be used for a long time. According to statistics from the Ministry of Industry and Information Technology, national lithium-ion battery production reached 324.0GWh in 2021, a year-on-year increase of 106.0%. As one of the cathode materials for lithium-ion batteries, the output of lithium manganate continues to increase. According to statistics from the China Nonferrous Metals Industry Association, my country’s lithium manganate output will reach 111,000 tons in 2021, a year-on-year increase of 19.6%.

In terms of market competition, Anhui Boshi Hi-Tech, Xinxiang Hongli, Southern Manganese, Jiaozuo Partner Nano and Guizhou Best are the leading companies in lithium manganate shipments in my country. Anhui Boshi Hi-Tech’s main products are power and capacity lithium manganate and other new cathode materials. In 2022, the company plans to use lithium manganate on a large scale in low-end energy storage and light vehicles, which will further expand the scope of lithium manganate. Application areas. In the first quarter of 2022, Anhui Boshi Hi-Tech occupied nearly 30.0% of my country’s lithium manganate market.

Industry analysts said that lithium manganate batteries, as the main product of lithium manganate, are widely used due to their low cost and good safety. However, compared with ternary batteries and lithium iron phosphate batteries, lithium manganate batteries have poor high-temperature performance and cycle performance and need to be used with other materials. As improved technology continues to improve, the market size of lithium manganate batteries is expected to further expand. In the context of the rapid development of the new energy industry, the increasingly strong demand for power batteries will bring broad market prospects for lithium manganate.
