Supercapacitors (SCs) are highly promising electrochemical energy conversion and storage devices. SCs display an outstanding power performance, excellent reversibility, long-term stability, simple operation, high feasibility for integration into electronic devices, including consumer electronics, memory backup systems, industrial management systems. The electrode materials determine the cell capacitance, operating voltage, density, time constant of SCs. Transition metal-based (TMEMs) among most electrodes SCs, due to their specific quick charging/discharging rates, in addition ease preparation a yield from low-cost earth-abundant resources. Binary transition metal sulfides (BTMSs) possess various advantages relative other TMEMs, higher capacity, electrical conductivity, redox properties, better quicker electron/ion diffusion, superior reversibility with long cycle life. Herein, inventory recent progress rational design BTMS deliberated, spaning methods operative conditions, mechanism. To help assist further development efficient durable current underlying challenges possible solutions identified addressed, emphasis on device performance vs type merits.
