NOVELTY - Preparation of lithium negative electrode involves processing graphene oxide dispersion to obtain graphene oxide film having a thickness of 1-200 mu m, drying at 30-300 degrees C for 1-72 hours, heating metal lithium at 200-500 degrees C at 1-50 degrees C/minute under an inert atmosphere, molding dried graphene oxide film, and reducing graphene oxide film by contacting graphene oxide with molten lithium for 1-120 seconds. USE - Preparation of lithium negative electrode for lithium battery e.g. lithium-oxygen battery and lithium-sulfur battery in the form of soft packed, wound cylinder and thin film (all claimed). ADVANTAGE - The prepared lithium negative electrode has excellent bending resistance, and provides battery having improved capacity and cyclic stability.
