Cellulose nanofiber–graphene all solid-state flexible supercapacitors

Abstract

Cellulose nanofibers are selected as nano-spacers, electrolyte nano-reservoirs and hierarchical nanostructure makers of CNF–RGO hybrid aerogel. The CNF–RGO hybrid aerogel based flexible supercapacitor exhibits high capacitance (207 F g−1). Taking its higher capacitance, low cost and environmentally friendly nature, they have great potential for use in flexible supercapacitors.
