With the progress of material modification technology, the industrialization process of manganese based cathode materials is accelerated. As one of the most important improvement directions of lithium iron phosphate, lithium manganese iron phosphate is expected to take the lead in industrial application. Recently, at the commencement ceremony of Tesla‘s Berlin super factory, musk said that Tesla is currently developing more materials to make batteries, and now sees the chemical potential of manganese based cathode batteries.
Compared with lithium iron phosphate, the biggest advantage of lithium manganese iron phosphate is to increase the voltage platform from 3.4V to 4.1V, which can increase the energy density of the battery by about 15%; Second, it can be mixed with ternary materials to reduce the cost. Third, there is no need to make major changes to the production line, which is conducive to mass production and cost reduction. Analysts pointed out that benefiting from the rapid growth of shipments of ternary cathode materials and lithium manganate materials, it is expected that the manganese consumption of lithium battery cathode materials will exceed 300000 tons in 2025, and the CAGR will be 32% from 2021 to 2025. With the increase of the permeability of new manganese based cathode materials, it is expected that the amount of manganese used for lithium batteries will surge, which is expected to increase to more than 1.3 million tons by 2035, more than 10 times that of 2021. However, the dominant position of manganese used for steel is difficult to change, and the “dual pattern” of manganese industry makes it easy to have a structural shortage of manganese raw materials for batteries.
According to the theme database of financial Associated Press, among the relevant listed companies:
Yibin Tianyuan Group Co.Ltd(002386) lithium iron manganese phosphate cathode material is in the pilot stage. The company’s new lithium iron manganese phosphate cathode material production line is fully compatible with the lithium iron manganese phosphate cathode material production line. Therefore, the company can produce lithium iron manganese phosphate cathode material through simple adjustment of formula and technology.
Sinosteel New Materials Co.Ltd(002057) battery grade manganese trioxide has a capacity of 5000 tons / year.
