Abstract

---

Recently transition metal chalcogenides have attracted much attention as electrode/electrocatalyst material for different energy storage and conversion applications. In the present study hierarchical interconnected manganese cobaltsulfide (MnCo2S4) nanoflakes were effectively deposited on conducting substrate by electrodeposition method followed by ion-exchange. The 3D-nature of conducting substrate facilitates the directional growth, exposing more active sites of the active material for electrochemical reactions at the electrode-electrolyte interface. The binder free electrode used as electrode/electrocatalyst for different applications such as Li-ion battery, supercapacitor, water splitting and methanol oxidation application. The MnCo2S4 electrode/electrocatalyst exhibits superior electrochemical performance with better stability, mainly attributed to the higher electrochemical surface area, superior electrode/ electrolyte contact offers fast ion diffusion and low electron transfer resistance. The present synthesis approach can open new era for large-scale applications of the novel materials for different electrochemical applications.
