Patent ID: 10141123

Abstract:
According to the present disclosure, a method for synthesizing a free-standing flexible electrode is provided. The method includes the steps of mixing a solution comprising vanadium powder, molybdenum powder and hydrogen peroxide to form a mixture comprising nanofibers represented by the formula of V0.07Mo0.93O3nH2O, filtering the mixture to form an electrode comprising the nanofibers, treating the electrode with an acidic solution, contacting the acid-treated electrode with a solution comprising monomers of a conductive polymer, and polymerizing the monomers in a medium comprising an oxidizing agent to form the conductive polymer. According to the present disclosure, there is also a free-standing flexible electrode comprising nanofibers comprised of molybdenum, vanadium and a conductive polymer, wherein the electrode is represented by a formula of X—V0.07Mo0.93O3n-H2O. In this formula, X is the conductive polymer and n is independently 1 or 2. According to the present disclosure, storage devices comprising the electrode as defined above, are also provided.
