NOVELTY - Supercapacitor current collector comprises aluminum and graphene with a mass ratio of (100-1000):1. USE - Used as supercapacitor current collector. ADVANTAGE - The current collector: has high tensile strength and good conductivity; provides long service life of the prepared super capacitor; and can reduce contact material of the resistor and enhance bonding property of the current collector and the electrode material. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Preparing supercapacitor current collector using liquid dispersant comprising ethanol, acetone or isoacetone and nonionic surfactant comprising at least one of polyvinyl alcohol, alkylphenol polyoxyethylene ether, and/or polyethylene glycol octylphenyl ether; and Supercapacitor.
