Binder-Free Manganese Oxide/Carbon Nanomaterials Thin Film Electrode for Supercapacitors

Abstract

A ternary thin film electrode was created by coating manganese oxide onto a network composed of single-walled carbon nanotubes and single-walled carbon nanohorns. The electrode exhibited a porous structure, which is a promising architecture for supercapacitors applications. The maximum specific capacitances of 357 F/g for total electrode at 1 A/g were achieved in 0.1 M Na₂SO₄ aqueous solution.
