摘要: Abstract Electrochemical hydrogen-storage is one of the prominent energy storage systems. In this work, hydrothermally synthesized copper sulfide (Cu2S) revealed a unique morphology micro-hexagons as envisioned through scanning electron microscopy measurements. hydrogen (EHS) performance was evaluated using various electrochemical techniques, such cyclic voltammetry, galvanostatic charge-discharge, and impedance spectroscopy The discharge capacity ~59.32 mAh g−1 obtained at an applied current density 1 A g−1. Further, analysis charge-storage mechanism indicates foremost contributions from redox processes. complimented with reasonable retention for 2500 cycles.
