Through pulping washing, secondary sintering, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC, it can increase the primary single crystal particle size of the ternary positive material, remove impurities and residual lithium in the ternary positive material, reduce the ph value of the ternary positive material, and remove fine particles in the ternary positive material. Reduce the specific surface area of the ternary cathode material; The ternary cathode material after slurry washing and secondary sintering reduces the contact area with the electrolyte and the probability of side reaction, and improves the chemical compatibility;
The ternary anode material has good electrochemical stability during the whole charge and discharge process, and maintains good thermal stability with the electrolyte to ensure the safety of the lithium battery. The ternary cathode material was tested by scanning electron microscope before washing and after washing and secondary sintering. Scanning electron microscopy showed that the primary single crystal size of the ternary anode MATERIAL increased significantly to 2 ~ 3µm after washing, secondary sintering, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal of iron, the fine particles decreased significantly, and the surface became smoother.
PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC effectively improves the compacting density of ternary cathode material and reduces the ph value. The ternary cathode material produced by the above process is made of lithium battery. The obtained lithium battery has many advantages such as high energy density and good cycle performance. It can greatly reduce the production cost of power battery.
