Three-dimensional "skin-framework" hybrid network as electroactive material platform for high-performance solid-state asymmetric supercapacitor.

ABSTRACT: Three-dimensional (3D) electrode materials are ideal candidates for use in fabricating high-performance supercapacitors (SCs), owing to their unique network structure and excellent electrochemical properties. In this study, an aerogel film produced by the freeze-drying self-aggregation of multiwall carbon nanotubes (MWCNTs) and cellulose nanofibers (CNFs) served as the "skin", and an inter-connected 3D network of nickel foam (NF) as the "framework", for the fabrication of an MWCNT/CNF-NF (called MCN) hybrid material with a distinct "skin-framework" architecture. Considering the metrics of excellent conductivity, high wettability, binder-free and unique 3D "skin-framework" structure, the MCN hybrid material has great potential as an electroactive material platform in constructing state-of-t
