Abstract

A three-dimensional network of carbon nanotubes (3DNC) coaxially coated with manganese oxides (MnOx) is used as an electrode for supercapacitors. 3DNC serves as a stable and conductive framework for controlled electrochemical deposition (ECD), and provides sufficient voids for fast ionic transport and diffusion. The coated thin layer MnOx reduces ion diffusion and electron transport distance, enabling fast reversible faradic reactions.
