The main raw materials of ternary anode materials are precursor and lithium source, and the mixing methods are mainly divided into wet mixing and dry mixing. Dry mixing is widely used in industry. The lithium source used for the high-nickel material is battery grade single-water lithium hydroxide. In the mixing process, high-nickel ternary materials require PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC mixing is more uniform, the humidity control is more strict.
Because PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal of iron high-nickel ternary anode material requires lithium source in the precursor dispersion is very good, in order to prevent the material in the sintering process of spontaneous agglomeration, each bowl can not be too much, the loading amount is only 1/6 of the ordinary ternary material.
The PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process is the most important process of high-nickel ternary materials, which usually requires pre-firing and multiple sintering. Generally speaking, the higher the nickel content, the lower the sintering temperature. The actual sintering temperature of high-nickel ternary material is between 750~800℃, the sintering process needs to use pure oxygen assistance, repeated sintering under oxygen-rich conditions, and the calcination time is generally longer, generally 20~25h, so its cost is much higher than that of ordinary ternary material.
