Physical Properties of Cassava (Manihot Esculenta) based on Gel Polymer Electrolyte for Zinc-Air Battery

Abstract

This is the continuous work for the characterization of cassava (Manihot Esculenta) based on gel polymer electrolyte for zinc-air battery. In this study, the aimed is to discover the physical properties based on the viscoelastic properties. The preparation of cassava gel electrolyte was by mixing and heated the cassava powder with deionized water. The cassava gel electrolyte continues by mixed with different concentration of potassium hydroxide (KOH). The viscoelastic of cassava gel electrolyte were valued in range of cassava and KOH concentration. From the observation found out the viscosity of cassava gel polymer electrolyte was remaining constant and not signification change in value as the concentration KOH was increased from 2 to 8 M.
