LITHIUM ion battery anode MATERIAL technology field, artificial graphite anode material PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal technology, lithium ion battery. The formulation technology of the artificial graphite anode material includes: the needle coke after sintering and grinding is mixed with the coating agent and then granulated to obtain the granulated material;
After the pelletizing MATERIAL is treated by graphite PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC magnetic removal technology, it is mixed with the surface modified material, and then carbonized to obtain the artificial graphite anode material. The surface modification material includes lithium titanate and coating agent. The capacity and cycle performance of lithium-ion batteries can be improved by adding surface modified materials during the second mixing and coating the materials after graphitization.
By sintering the needle coke, the vibration density of the MATERIAL after grinding can be increased, so as to increase the filling density of graphite furnace in the process of graphite PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC removal technology, reduce the number of graphitization furnaces, reduce power consumption, and reduce production costs.
