Effect of ethylene glycol on deep eutectic solvent properties: dual functionality of zinc chloride as hydrogen bond acceptor and salt

Year: 2025

Type: article

Abstract: This study presents the development and analysis of novel deep eutectic solvents (DESs) composed of glycerol, zinc chloride, and ethylene glycol for application in supercapacitors. Various molar ratios were explored to optimize the physical and electrochemical properties of the DESs. The formulation with moderate ethylene glycol content demonstrated improved viscosity and ionic conductivity, which facilitated enhanced ionic mobility. Electrochemical characterisation confirmed superior specific capacitance and ionic conductivity for the optimized sample. This work underscores the critical role of composition tuning in DES systems to achieve an optimal balance between viscosity and conductivity, ultimately advancing the performance of supercapacitor devices.
