Abstract

In this study, polymer electrolytes consist of methyl cellulose (MC) and different wt% of potassium hydroxide (KOH) salt were prepared using a solution cast technique. The optimum percentage of salt and plasticizer that gave the highest value of electrical conductivity of the sample was determined. Impedance spectroscopy technique was carried out in order to determine the electrical conductivity value. The highest conductivity of unplasticized sample was 5.64* 10"6 S/cm for MC-KOH (70:30). Meanwhile, the highest conductivity for plasticized sample was 3.58* 10"3 S/cm for MC-KOH-EC (46.67:20:33.33). These conductivities were calculated using the bulk resistance value obtained from the impedance plot in frequency range between 100 Hz and 1 MHz. For application in the battery system, the highest conducting of plasticized sample was used as the electrolyte. The battery was evaluated using the open-circuit voltage (OCV) and charge-discharge characteristics.
