Direct Synthesis of cubic shaped Ag 2 S on Ni mesh as Binder-free Electrodes for Energy Storage Applications

A facile approach of chemical bath deposition was proposed to fabricate direct synthesis of silver sulphide (Ag 2 S) on nickel (Ni) mesh without involvement for binders for supercapacitor electrodes. The phase purity, structure, composition, morphology, microstructure of the as-fabricated Ag 2 S electrode was validated from its corresponding comprehensive characterization tools. The electrochemical characteristics of the Ag 2 S electrodes were evaluated by recording the electrochemical measurements such as cyclic voltammetry and charge/discharge profile in a three electrode configuration system. Ag 2 S employed as working electrode demonstrates notable faradaic behaviour including high reversible specific capacitance value of 179 C/g at a constant charge/discharge current density of 1 A/g with high cyclic stability which is relatively good as compared with other sulphide based materials. The experimental results ensure fabricated binder-free Ag 2 S electrodes exhibits better electrochemical performance and suitable for potential electrodes in electrochemical energy storage applications.
