Abstract
A method for fabricating an electrode for a rechargeable lithium battery which includes depositing a thin film composed of active material capable of alloy formation with lithium on a current collector made of a metal incapable of alloy formation with lithium, by using a process for depositing a thin film by supplying a material from a gas phase, characterized in that the thin film of active material is deposited at such a temperature that enables formation of a mixed layer via diffusion of a constituent of the current collector into the thin film in the vicinity of an interface therebetween.
