▎ 摘　　要

NOVELTY - Processing graphene comprises: combining few-layer graphene with a poly(alkylene oxide); drying to form a graphene/poly(alkylene oxide) composite; and calcining the graphene/poly(alkylene oxide) composite thus formed in an inert atmosphere. USE - The method is useful: for processing graphene which is used in a capacitive deionization application or in a rechargeable battery application, in a cathode, and a rechargeable battery e.g. an aluminum-ion battery (all claimed). ADVANTAGE - The method: provides an attractive new-emerging battery technology; is low cost and safety; and has high gravimetric capacity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) processed graphene, preferably surface-perforated graphene, produced by, obtained by or obtainable by the process; (2) processed graphene having the X-ray diffraction (XRD) profile demonstrates at least one shoulder peak, preferably two shoulder peaks, at less than 26 degrees 2 theta ; (3) processed graphene comprising a few-layer feature, preferably a three-layer feature, where the graphene further comprises at least one features comprising in-plane nanopores with dimensions of 1.5-3.5 nm, a greater than 50% expanded interlayer lattice, an expansion interlayer distance of greater than 3.4 Angstrom , and less than 4% atomic oxygen/carbon; (4) a cathode comprising the graphene; (5) preparing the cathode comprising mixing the including the graphene with a binder, a solvent and optionally a surfactant, emulsifier or dispersant, applying the mixture to a cathode substrate, and drying the mixture to remove the solvent; (6) a cathode obtained by the process; (7) a rechargeable battery comprising the graphene or the cathode; and (8) an aluminum-ion battery comprising the graphene or the cathode.
