A hybrid aerogel of Co–Al layered double hydroxide/graphene with three-dimensional porous structure as a novel electrode material for supercapacitors

Abstract

3D porous Co–Al layered double hydroxide/graphene hybrid aerogel was prepared by a facile <italic>in situ</italic> hydrothermal method and showed high electrical conductivity, mechanical flexibility, and good electrochemical performance for supercapacitors.
