Method of coating graphite on hard carbon and hard carbon coated graphite

摘要

The present invention relates to a method for coating graphite on the surface of the hard carbon and to a hard carbon coated with the graphite in order to improve the initial charge and discharge efficiency of the hard carbon used as a negative electrode material of the secondary battery. According to the present invention, it is possible to efficiently coat hard carbon, which is not easy to coat conventionally.;Graphite, Hard Carbon, Coating, Agglomeration, Secondary Battery
