Structure of an asymmetric supercapacitor and method of preparation thereof

Abstract

A structure of an asymmetric supercapacitor and a preparation method thereof is disclosed. In some implementations, the preparation comprises the steps of forming a polyaniline (PANI) nanowire on carbon cloth (CC) substrate (PANI/CC) by polymerization of an aniline, depositing a cobalt-nickel layer double hydroxides (CoNi-LDHs) on the PANI/CC by a hydrothermal process, and calcining of the cobalt-nickel layer double hydroxides (CoNi-LDHs) in the PANI/CC at a high temperature to form a metal carbide (CoC@NiC) on the carbon cloth. The structure of the asymmetric supercapacitor includes a metal carbide (CoC@NiC) as a positive electrode, a tungsten trioxide (WO3@C) as a negative electrode, and a poly (vinyl alcohol)/Potassium hydroxide (PVA/KOH) as an electrolyte gel.
