The high alkali MATERIAL is washed for alkali reduction, while the low alkali material is not washed, and the washing part of the final PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC product is reduced, which reduces the influence of the washing process and the drying process after washing on the ternary anode material product. The low alkali material is not washed so that the discharge specific capacity of the final ternary cathode material is slightly worse than that of the ternary cathode material after complete washing under the premise of meeting the use requirements.
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic significantly improves the discharge efficiency cycle retention rate, especially this method provided by the technology, due to the reduction of water washing amount, can shorten the manufacturing cycle of materials, reduce production costs, This can bring more significant economic benefits for the preparation process of lithium battery materials, which has been developed more mature.
A high nickel ternary cathode MATERIAL and a preparation method for PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic and a lithium battery are provided to ameliorate at least one of the problems mentioned in the background technology. The removal of water involves pressing the washed product and then drying it. In the process of sintering the precursor and lithium hydroxide to obtain high alkali material, the sintering temperature is 700~830℃. In the process of mixed sintering of precursor and lithium hydroxide to obtain low alkali material, the sintering temperature is 730~850℃. When the coating material is sintered, the sintering temperature is 200~600℃.
