Ternary materials according to the different content of nickel, cobalt and manganese, there can be many kinds, such as the common ncm333, ncm523, ncm622, ncm811, etc., which is characterized by the increase of nickel content, the gram capacity of the material will increase. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC treatment of high-nickel ternary cathode material has the characteristics of high capacity, high cycle, cost-effective, can fully meet the new energy vehicle subsidies, and in the end market can make the series of energy vehicles competitive.
However, due to the low sintering temperature and high residual alkali of high-nickel terpolymer anode materials, the common preparation process is: precursor mixed with LITHIUM hydroxide, primary sintering, crushing, washing, press filtration, drying, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, coating, secondary firing. Due to the low melting point of high nickel precursors, lithium hydroxide with low decomposition temperature is generally selected as a lithium source due to process cost considerations, and lithium hydroxide as a lithium source will have alkali or other impurities in the prepared ternary cathode material, causing problems such as battery gas production.
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC is an effective method to remove impurities on the surface of high-nickel ternary materials. Through deionized water washing, the release of o2 and co2 of materials under high voltage can be effectively reduced. However, the high drying temperature after washing will cause the impedance of the battery to increase significantly, and affect the cycle life of the battery.
