▎ 摘  要

NOVELTY - High performance printing ink is composed of carbon quantum dots, graphene oxide, surfactant and solvent. USE - High performance printing ink used in flexible electrode for flexible all-solid-state supercapacitor(all claimed). ADVANTAGE - The high performance printing ink has excellent electrochemical properties and cycling stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a method for preparing printing ink, which involves adding carbon quantum dots, dispersing graphene oxide in solvent, adding surfactant, mixing and stirring by ultrasonic and centrifuging to obtain high performance printing ink; (2) a flexible electrode for flexible all-solid-state supercapacitor, which is obtained by drying inkjet printing ink on surface of flexible substrate, where ink is high-performance printable ink; and (3) a flexible full-solid-state super capacitor, which comprises electrolyte layer as center that is composed of symmetrical first metal film which is compounded with collector and first flexible electrode and second metal thin film collector and second flexible electrode.
