Abstract

Well‐organized mesoporous carbon impregnated with In2O3 nanoparticles can be used as supercapacitor electrodes. The uniformly distributed In2O3 nanoparticles in the mesoporous carbon matrix are effectively utilized for the enhancement of capacitive performance.

Scalable self-growth of Ni@NiO core-shell electrode with ultrahigh capacitance and super-long cyclic stability for supercapacitors

“…One promising strategy to improve the energy density is to design nanostructured electrode materials with large surface areas and good structural stability. Various nanostructures including nanoparticles, 8 nanowires, 9,10 nanotubes 11 and nanosheets 12,13 have been explored as SC electrodes and have exhibited improved electrochemical performance. Among these nanostructures, three-dimensional (3D) porous nanoarchitectures have been demonstrated to be a promising candidate for SCs as these nanoarchitectures can offer large interfacial areas, reduced ionic diffusion distances and facilitate charge separation and transport.…”
