Incorporation of homogeneous Co₃O₄ into a nitrogen-doped carbon aerogel via a facile in situ synthesis method: implications for high performance asymmetric supercapacitors

Abstract

A novel high-performance electrode material, nitrogen-doped carbon aerogel/cobalt oxide (NCA/Co₃O₄) material, was prepared by a facile, one step and <italic>in situ</italic> coating method, followed by a freeze-drying process.
