Spray processing of TiO2 nanoparticle/ionomer coatings on carbon nanotube scaffolds for solid-state supercapacitors

Author affiliations

Abstract

A one-step scalable spray technique was used to fabricate solid-state supercapacitors with multi-wall carbon nanotube/TiO2-nanoparticle/ionomer hybrid electrodes. The 3D electrode nanostructure was designed for mobile H+ ion generation and fast electron-ion dual conduction, achieving an unusual and highly attractive balance of energy (31.8 W h kg−1) and power (14.9 kW kg−1) densities at 1 A g−1 that are amongst highest reported for solid-state supercapacitors.
