Title:
二次電池
Document Type and Number:
Japanese Patent JP5894313
Kind Code:
B2
Abstract:
To provide graphene through which ions can transfer in the direction perpendicular to a plane of the graphene. Multilayer graphene includes a plurality of graphenes stacked in a layered manner. The plurality of graphenes contain a six-membered ring composed of carbon atoms, a poly-membered ring which is a seven or more-membered ring composed of carbon atoms or carbon atoms and one or more oxygen atoms, and an oxygen atom bonded to one of the carbon atoms in the six-membered ring and the poly-membered ring, which is a seven or more-membered ring. The interlayer distance between adjacent graphenes of the plurality of graphenes is greater than 0.34 nm and less than or equal to 0.5 nm, preferably greater than or equal to 0.38 nm and less than or equal to 0.42 nm.
