Large scalable nickel phosphide/nickel@carbon cloth-based flexible composite electrodes for symmetric supercapacitors

A flexible Ni 3 P/Ni@CC composite electrode with remarkable mechanical robustness is developed by a scalable and facile synthetic approach. The as-constructed symmetric supercapacitor demonstrates impressive energy density (51.1 W h kg −1 ) at a high power density (3500 W kg −1 ) along with excellent cycling stability. Electroless deposition of low-cost and large scalable Ni 3 P/Ni hybrid film on carbon cloth as a flexible composite electrode with remarkable mechanical robustness for high performance supercapacitors.
