Abstract
This study reports a process to prepare CoxNi1−xS (x = 0, 0.25, 0.5, 0.75 and 1) samples by hydrothermal process at 250 °C using stoichiometric weight ratios of raw materials. The prepared powder samples were annealed in Ar atmosphere at 450 °C for 3 h. The crystal structure of prepared annealed CoxNi1−xS samples was characterized by XRD. SEM investigations were carried out explaining the morphology of these samples. Electrochemical impedance spectra (EIS) measurements, Cyclic voltammetric (CV) and galvanostatic measurements were carried out. The life cycle performance was carried out for the cells and Li/Co0.25Ni0.75S cell gave specific discharge capacities of about 330 mA h g−1.
