PROBLEM TO BE SOLVED: To mass-produce highly-pure graphite oxide (or graphene oxide).SOLUTION: Graphite is oxidized by an oxidizer, so that a graphite oxide solution is obtained, and electrodialysis is performed on the graphite oxide solution to remove aqueous ions in the solution, whereby the purity of graphite oxide is increased. Graphene oxide obtained from the graphite oxide thus obtained as materials is mixed with powder, and the mixture is reduced, whereby graphene exhibiting conductive properties is yielded and the powder can be bonded. Such graphene can be used, for example, instead of a conduction auxiliary agent or a binder of a variety of batteries.SELECTED DRAWING: Figure 1 |
