Extraordinary rate capability achieved by a 3D “skeleton/skin” carbon aerogel–polyaniline hybrid with vertically aligned pores†
Abstract
A 3D “skeleton/skin” carbon aerogel–polyaniline (CA–PANI) hybrid with vertically aligned pores exhibits an extraordinary rate capability. A high capacity retention (95%) has been achieved when the current density is increased from 1 to 100 A g−1.
