dc.description.abstractElectrochemical hydrogen-storage is one of the prominent energy storage systems. In this work, the hydrothermally synthesized copper sulfide (Cu<inf>2</inf>S) revealed a unique morphology of micro-hexagons as envisioned through scanning electron microscopy measurements. Electrochemical hydrogen storage (EHS) performance was evaluated using various electrochemical techniques, such as cyclic voltammetry, galvanostatic charge-discharge, and impedance spectroscopy measurements. The hydrogen discharge capacity of ~59.32 mAh g?1 was obtained at an applied current density of 1 A g?1. Further, the analysis of the charge-storage mechanism indicates foremost contributions from the redox processes. The prominent hydrogen storage performance is complimented with reasonable cyclic retention for 2500 cycles. © 2020 Hydrogen Energy Publications LLC
