▎ 摘　　要

NOVELTY - Porous composite electrode comprises organic compounds having redox centers; graphene non-covalently bound to the organic compound; and cellulose fibers that disperse the organic compound and the graphene and form a porous structure. USE - The porous composite electrode is useful for secondary battery (claimed) and various organic electrode materials. ADVANTAGE - The porous composite electrode for high-performance secondary battery has stable oxidation-reduction activity, rapid charge movement, and high mechanical properties simultaneously, high energy density and excellent cycle characteristics; is environmentally friendly; has excellent mechanical properties high-performance secondary battery; and improves the lifespan characteristics. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) manufacturing porous composite electrode, comprising exfoliating graphene from an intercalation compound formed from graphite in a stripping solution containing an organic compound having a redox center to non-covalently bond the organic compound and the grapheme, freezing the active material composition comprising graphene, cellulose fibers and a solvent combined with the organic compound, and freeze-drying the frozen active material composition to remove the solvent to form a porous structure; and (2) secondary battery comprising a first electrode comprising the porous composite electrode, a second electrode spaced apart from the first electrode by a separator, and an electrolyte for transferring ions between the first electrode and the second electrode.
