Commercial design of electrode materials: low cost raw material niobium carbide as versatile precursor for advanced supercapacitors

Reviews of current supercapacitor characteristics, synthesis methods of electrode materials, and NbC electrode materials are presented. And a new solution is proposed for how to solve the method of obtaining Nb in electrode materials. A new material to extract niobium resources with coke as a matrix, through the in situ synthesis of polyaniline in the pores of coke prepared polyaniline/coke composite materials, which will be used for the extraction of niobium resources from the leach solution of Bayan Obo tailings, not only efficiently extracted niobium resources but also solved the problem of environmental protection.
