Title (EN) HIGH-PERFORMANCE SOLID-STATE SUPERCAPACITORS AND MICROSUPERCAPACITORS DERIVED FROM PRINTABLE GRAPHENE INKS
(FR) SUPERCONDENSATEURS À SEMI-CONDUCTEURS HAUTE PERFORMANCE ET MICRO-SUPERCONDENSATEURS DÉRIVÉS D'ENCRES DE GRAPHÈNE IMPRIMABLES
Abstract:
(EN) Solid-state supercapacitors and microsupercapacitors comprising printed graphene electrodies and related method of fabricating a graphene capacitor, said method comprising providing a graphene ink composition comprising graphene and an ethyl cellulose, said composition not prepared from graphene oxide, depositing said graphene ink composition on a substrate, annealing said graphene ink composition to decompose said ethyl cellulose and provide an electrode component comprising graphene, and coupling electrolyte and metallic lead components to said electrode component.
(FR) L'invention concerne des supercondensateurs à semi-conducteurs et des micro-supercondensateurs comprenant des électrodes en graphène imprimé, ainsi que des procédés de préparation associés.
