Title:
Apparatus for electrodialysis
Document Type and Number:
Japanese Patent JP6063077
Kind Code:
B2
Abstract:
Highly-pure graphite oxide, graphene oxide, or graphene is mass-produced. 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, whereby the purity of graphite oxide is increased. Graphene oxide manufactured using the graphite oxide 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 instead of a conduction auxiliary agent or a binder of a variety of batteries.
