摘要：NOVELTY - A cobalt tetraoxide/carbon composite electrode material preparing method involves coating zeolitic imidazolate framework-67 nano-particles with a uniform phenolic resin in situ on the outside of nanoparticle to form a zeolitic imidazolate framework-67-PR composite, after treatment to obtain cobalt tetraoxide/carbon composite electrode, where zeolitic imidazolate framework-67 nanoparticles have a uniform size distribution, and the particle diameter is 250-300 nm, the phenolic resin is uniformly wrapped on the zeolitic imidazolate framework-67, and the composite particle size is close to zeolitic imidazolate framework-67. USE - Method for preparing cobalt tetraoxide/carbon composite electrode material for use as an electrode material of supercapacitor (claimed). ADVANTAGE - The electrode material has improves specific capacity, energy density and cycle stability and better application prospect in the field of supercapacitor materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a cobalt tetraoxide/carbon composite electrode material obtained by the method.
