▎ 摘  要

NOVELTY - The system is made of graphene oxide, ion liquid and polymer base material, where weight ratio of the ion liquid to graphene oxide is about 1: 1-10, 000 and weight ratio of ion liquid to polymer matrix is about 1: 0.5-100. Positive ion and negative ion are dipped in the ion liquid. USE - Ion liquid gel electrolyte system for a super capacitor (claimed). ADVANTAGE - The system improves energy density of the super capacitor, utilization rate property and circulation property. DETAILED DESCRIPTION - The positive ion is selected from a group consisting of dialkyl substituted imidazole ion, trialkyl-substituted imidazole ion and N-alkyl substituted pyridine iron. The negative ion is selected from a group consisting of tetra-fluoroborate, hexafluorophosphate, tri-fluoromethane sulfonic acid, tetra-alkyl phosphonium and perfluoroalkylsulfonyl. The polymer base material is selected from a group consisting of polyoxyethylene (PEO), polymethyl methacrylate vinegar (PMMA), polypropylene nitrile (PAN), polyvinylidene fluoride (PVDF), copolymer of vinylidene fluoride (VDF) and hexafluoropropylene (HFP). INDEPENDENT CLAIMS are also included for the following: (1) a super capacitor (2) a super capacitor preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a photograph of an ion liquid gel electrolyte system.
