Electrochemical performance of transition metal sulfide by employing different synthesis techniques for hybrid batteries

Hybrid batteries a well‐known electrochemical energy storage technology that comprises of both supercapacitor and battery characteristics at the same time. The hybrid batteries can fulfill the current global energy quest as they have obtained high energy density (battery) and high‐power characteristics (supercapacitor). Here, we have demonstrated the effect of synthesis technique on the electrochemical performance of manganese sulfide (MnS) by mainly opting sonochemical and hydrothermal approach. Initially, the electrochemical characterizations of MnS were analyzed in three electrode setup. Electrochemical measurements in particular cyclic voltammetry, galvanostatic charge discharge, and impedance spectroscopy were studied to scrutinize the nature of the electrodes. The hydrothermally synthesized MnS shows battery grade nature with superior specific capacity of 608.08 C/g at 2.2 A/g. On account of …
