Ionic Transport and Electrochemical Properties of PMMA-Based Gel Polymer Electrolytes for Magnesium Batteries

Article Preview

Abstract:

Poly (methyl) methacrylate (PMMA)-based gel polymer electrolytes (GPEs) containing magnesium triflate, Mg (CF3SO3)2 salt were prepared using solution casting technique. Different concentrations of Mg (CF3SO3)2 ranging from 5 wt.% to 30 wt.% have been added into a mixture of ethylene carbonate (EC) and propylene carbonate (PC) with a fixed mass ratio of 2:1. These free-standing GPE films were characterized using electrochemical impedance spectroscopy (EIS), linear sweep voltammetry (LSV) and cyclic voltammetry (CV). The highest ionic conductivity of 1.27 x 10-3 S cm-1 is obtained from the GPE film containing 20 wt.% of Mg (CF3SO3)2 salt. The electrochemical window stability has been found in the range of-2.5 V to 2.5 V for the highest conducting GPE film. This value is considerably high enough for the GPE film to be used as electrolyte in magnesium rechargeable batteries.
