摘要
Systems for the production of graphene oxide sheets are provided. The systems include electro-deposition and spray deposition techniques. The graphene oxide sheets may be used as pre-cursors for the formation of porous graphene network (PGN) anodes and lithiated porous graphene (Li-PGN) cathodes. The method of making PGN electrodes includes thermally reducing a pre-cursor sheet of graphene oxide to provide a PGN anode and exposing the sheet to lithium or a lithium-containing compound to produce a Li-PGN cathode. The Li-PGN cathode and PGN anode may be combined with an electrolyte to provide an “all-carbon” battery that is useful in various applications, such as automotive applications.
