ELECTRODE FOR LITHIUM SECONDARY BATTERY, METHOD FOR MANUFACTURING SAME, AND LITHIUM SECONDARY BATTERY

摘要

An electrode for a lithium secondary battery comprises an active material body and a diamond-like carbon (DLC) layer covering the active material body, wherein the active material body includes silicon nanopowders, a carbon-based conductive material, and a binder. The DLC layer can suppress the volumetric expansion of the active material body. The DLC layer can suppress a reaction between the active material body and an electrolyte. Therefore, when the electrode including the DLC layer is applied to the lithium secondary battery, the lithium secondary battery can have stable cycle properties.
