Title: COMPOSITE MATERIAL FOR PAPER ELECTRODE, PAPER ELECTRODE, CONDUCTIVE GRAPHENE SHEET, PAPER BATTERY, AND APPLICATION THEREOF
Abstract:
The present invention provides a paper electrode composite material, and a paper electrode, conductive graphene sheet, and paper battery, and an application thereof. The paper electrode composite material mainly comprises 5-10% by weight of a carbon material, 34-57% by weight of a paper pulp, and 6-9% by weight of an auxiliary agent. The paper electrode mainly comprises 30-50% by weight of a positive electrode active material and 50-70% by weight of the composite material. The conductive graphene paper mainly comprises 10-50% by weight of a nanocarbon material, 40-75% by weight of the paper pulp, and 8-18% of the auxiliary agent. The nanocarbon material comprises at least a graphene. The auxiliary agent is a composition comprising at least one or more of the following: a modified starch, anionic polyacrylamide, poly(vinyl alcohol), and carboxymethyl cellulose. The invention can be applied to the technical field of paper batteries and provides advantages such as improved specific capacity, stable battery performance, longer battery life, and the like.
