Catalytic graphite material, preparation method, and use thereof

Abstract

Provided in the present application are a catalytic graphite material, a preparation method and a use thereof. The catalytic graphite material comprises flake-shaped graphite and hollow spherical graphite particles. The catalytic graphite material has a 3R phase. The catalytic graphite material has a high purity, a high degree of graphitization, and has a 3R phase. The presence of the 3R phase provides more embedding sites for lithium ions. When the catalytic graphite material is used for a negative electrode material of a lithium-ion battery, the catalytic graphite material exhibits the characteristics of high capacity, high first efficiency, and low expansion, thereby significantly increasing the electrochemical properties of the lithium-ion battery such as the capacity, the initial efficiency, etc.
