Abstract
A composite electrode and a lithium-based battery are disclosed, wherein the composite electrode comprises: a substrate and a conductive layer formed on the substrate, wherein the conductive layer comprises graphite powders, Si-based powders, Ti-based powders, or a combination thereof embedded in a conductive matrix and coated with diamond films, and the diamond films are formed of diamond grains. The novel electrodes of the present invention when used in the Li-based battery can provide superior performance including excellent chemical inertness, physical integrity, and charge-discharge cycling life-time, and exhibit high electric conductivity and excellent lithium ion permeability.
