NOVELTY - Preparing metal lithium complex metal lithium cathode comprises (i) preparing graphene oxide film by processing a graphene oxide dispersion, where the thickness of which is 1-200 mu m, (ii) drying graphene oxide film at 30-300 degrees C for 1-72 hours, (iii) patterning the dried graphene oxide film using a high power light source to cover the appropriate mask the graphene oxide film is photoetched to remove the exposed portion of the graphene oxide film, (iv) carrying out the metal lithium is heat treatment in an inert atmosphere by a heating device at 1-50 degrees C/minutes, and the final temperature is 200-500 degrees C, and (v) contacting graphitized graphene oxide is brought into contact with the molten metal lithium for period of 1-120 seconds. USE - The metal lithium complex metal lithium cathode is useful for controlling the lateral growth of dendrites and improving the capacity and cycle stability of the battery.
