Negative active material for lithium rechargeable batteries and method of fabricating same |
摘要 |
Disclosed is a negative active material for a lithium rechargeable battery comprising a core having a carbon source with a surface-treatment layer formed on the surface of the core. The surface-treatment layer has at least one amorphous, semi crystalline, or crystalline coating element compound selected from the group consisting of coating-element-included hydroxides, coating-element-included oxyhydroxides, coating-element-included-oxycarbonates, and coating-element-included hydroxidecarbonates. Also disclosed is a method of preparing a negative active material for a lithium rechargeable battery comprising coating a carbon source with a coating liquid, and drying the carbon source. The coating liquid comprises a solute of a coating element source and a solvent of a mixture of an organic solvent and water.
