Description

technical field [0001] The invention relates to an electrode production equipment, in particular to a graphite-coated carbonization equipment for lithium battery electrode production. Background technique [0002] Graphite materials such as graphite powder and graphite film are used more and more widely due to their unique electrical and thermal properties. Graphite used in lithium-ion batteries has the advantages of high working voltage, high specific energy, light weight, small size, long cycle life, fast charge and discharge, and no environmental pollution. However, the compatibility of graphite and electrolyte is poor, which limits Application of pure graphite in Li-ion batteries. Therefore, it is necessary to modify the graphite material, and coat a layer of amorphous carbon material on the surface of the graphite to increase the tap density and increase the charge and discharge capacity of the battery. The reaction process of coated graphite is generally to disperse ...
