Title:
SURFACE-TREATED GRAPHENE, SURFACE-TREATED GRAPHENE/ORGANIC SOLVENT DISPERSION LIQUID, SURFACE-TREATED GRAPHENE/ELECTRODE ACTIVE MATERIAL COMPOSITE PARTICLES AND ELECTRODE PASTE
Document Type and Number:
WIPO Patent Application WO/2017/154533
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a graphene which has high dispersibility, high electrical conductivity and oxidation resistance, namely a graphene which has high electrochemical stability. In order to achieve the above-described purpose, a surface-treated graphene according to the present invention is obtained by having a compound represented by general formula (1) or a neutralized salt thereof adhere to a graphene. (In general formula (1), A represents a benzene-based aromatic group with a condensation number of 1-4, which has no phenolic hydroxy group; R1 represents a direct bond, a divalent hydrocarbon group having 1-12 carbon atoms, or a divalent organic group having 1-12 carbon atoms, which has a structure selected from the group consisting of an ether bond, an ester bond, an alcohol structure and a carbonyl structure; each of R2 and R3 independently represents a hydrogen atom, a hydrocarbon group having 1-12 carbon atoms, or an organic group having 1-12 carbon atoms, which has a structure selected from the group consisting of an ether bond, an ester bond, an alcohol structure and a carbonyl structure; and n represents an integer of 1-6.)
