Reverse voltage pulse deposition of a porous polyaniline/Mn–Co sulfide composite cathode material for modified Zn-ion hybrid supercapacitors

Abstract

For expanding the working potential window and reducing the self-discharge for a Zn-ion hybrid supercapacitor, a cathode of the Mn–Co-sulfide–polyaniline (MCS–PANi) composite was prepared by the reverse voltage pulse electrodeposition method.
