Abstract

Binary room temperature molten electrolytes based on acetamide and zinc perchlorate have been prepared and characterized. The electrolytes are found to be highly zinc ion-conducting with very favorable physicochemical and electrochemical characteristics. Raman and infrared spectroscopic studies reveal the presence of large free-ion concentration in the molten liquid. This is corroborated by the high conductivity observed under ambient conditions. Rechargeable zinc batteries assembled using γ-MnO2 as the cathode and Zn as the anode with the molten electrolyte show high discharge capacities over several cycles, indicating excellent reversibility. This unique class of acetamide-based, room temperature molten liquids may become viable and green alternative electrolytes for rechargeable zinc-based secondary batteries.

Graphical abstractZinc ion-conducting binary room temperature molten electrolytes consisting of acetamide and zinc perchlorate show ionic conductivity of the order of as high as 6.3 mS cm−1 at 298 K and high discharge capacity in rechargeable zinc-based batteries.Figure optionsDownload full-size imageDownload as PowerPoint slide
