Of the main components of lithium ion battery materials including electrolyte, isolation materials, anode materials, cathode materials occupy a large proportion, because the performance of the cathode materials directly affects the performance of the lithium ion battery, its cost also directly determine the battery cost, in the process of processing, lithium battery cathode materials contains iron chips need to remove, so you need to use to PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC screen in addition to the iron device.
NCM ternary development trend is high nickization. The ternary cathode material is mainly improved through the use of PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC to improve the nickel content, the charging voltage upper limit and the compaction density. The high nickel cathode usually refers to the material model with a relative nickel content of more than 0.6 (including). Thus, in terms of energy density, NCA> NCM811> NCM622> NCM523> NCM333.
Terternary materials produce nickel, cobalt, manganese hydroxide, lithium carbonate and other doped elements as raw materials, batching, mixing, sintering, crushing, batch, screening, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC iron removal, packaging and other processes. At present, the investment of ternary material production line equipment (excluding precursor) is roughly 20,000 yuan / ton (the high nickel ternary investment is large).
