Abstract:
Sodium-carboxymethylcellulose (NaCMC) based solid polymer electrolytes (SPEs) have been prepared using solution casting and followed by soaking the film into the optimized polysulfide solution for 68 seconds. Impedance studies of the polymer electrolytes have been done using electrochemical impedance spectroscopy (EIS). The NaCMC/polysulfide electrolyte exhibited a room temperature (RT) ionic conductivity of 2.79×10−5 S·cm−1. The conductivity increased to 1.11×10−4 S cm−1 when the NaCMC/polysulfide electrolyte was plasticized with 40 wt.% of ethylene carbonate (EC). The conductivity-temperature relationship of the plasticized electrolyte obeys the Arrhenius rule with activation energy for plasticized film at 40 wt.% EC is as low as 0.25 eV. The transport properties, Diffusion coefficient (D), number density of mobile ions (n), and its mobility (µ) were also calculated.
