N2 - Solid polymer blend electrolyte films composed of 70 wt.% of chitosan (CS) and 30 wt.% of methylcellulose (MC) were prepared with different weight percentages of MgCl2 by solution casting method. FTIR analysis demonstrated the interactions between blend and MgCl2, XRD study revealed the amorphous nature of the films. Thermogravimetric analysis (TGA) was carried out to study the thermal stability. Electrical impedance spectroscopy (EIS) study showed that the bulk resistance decreased with increasing salt concentration and is due to the influence of carrier concentration. From EIS measurement, the highest value of DC conductivity at ambient temperature (30 °C) was found to be 2.75 × 10−3 Scm−1 for the sample containing 30 wt.% of MgCl2. The voltage stability window of the highest conducting film was found to be 3.86 V. The total ionic transference number was found to be 0.98. Finally, the highest conducting polymer electrolyte was employed to construct a primary magnesium ion battery.
