Abstract

Energy security is becoming a major concern across the globe which has boosted development of battery technology. Electrolytes play a major part in any battery systems where they are usually in the form of liquid. Electrolytes are usually produced by dissolving ionic dopants in organic solvents. This paper reports the electrical behavior of a plasticized biopolymer film system. The biopolymer film showed good ionic conductivity enhancement when plasticized with ethylene carbonate where optimum value of 7.41 × 10^-4 S/cm was obtained. The ionic conductivity improvement was aided by lower activation energy, E_a and the biopolymer film followed the Arrhenius behavior. Dielectric analysis was done to further analyze electrical properties of the biopolymer film.
