Title:
ELECTRODE, SECONDARY BATTERY, MOVING BODY, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/009019
Kind Code:
A1
Abstract:
Provided is an electrode that exhibits excellent properties. Also provided is an active material that exhibits excellent properties. Also provided is a novel silicon material. The electrode has a plurality of particles and a graphene compound, and at least a portion of the surface of each of the plurality of particles is terminated by an oxygen-containing functional group. The graphene compound encloses the perimeter of the plurality of particles so as to envelop the same. The graphene compound is a graphene that has, in the two-dimensional structure formed by the 6-membered carbon rings, at least one of the following: carbon atoms terminated by the hydrogen atom and carbon atoms terminated by the fluorine atom.
