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

Abstract

A flexible Ni₃P/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.
