Abstract

Manganese sulfide is promising material for electrochemical applications. In this work, crystalline, porous, and nanostructured MnS₂ and MnS₂/carbon nanotube electrodes are prepared using dip dry and successive ionic layer adsorption and reaction (SILAR) methods at room temperature (300 K). Comparative charge storage of MnS₂ and MnS₂/carbon nanotube is examined in aqueous Na₂SO₄ and KOH electrolytes. The superior charge storage of MnS₂/CNT in Na₂SO₄ is observed with highest specific capacitance of 855 F g⁻¹ at 1 mA cm⁻² current density and 90.1% capacitance retention for continuous 5000 charge discharge cycles. The improvement in electrochemical charge storage of MnS₂/CNT is associated with reduced electron transfer path and low equivalent series resistance (ESR) in Na₂SO₄.
