Abstract
The solid biopolymer electrolyte (SBE) system has been formed by introducing various compositions of oleic acid as ionic dopant into carboxymethyl cellulose via solution casting techniques. The highest conductivity achieved at room temperature is 2.11 x 10-5 S cm-1. The coin cell proton battery were fabricated with the configuration of Zn + ZnSO4.7H2O | SBEs | MnO2 for the highest conductivity SBEs. The open circuit voltage (OCV) of the fabricated proton battery with the best performance is 0.87 V at ambient temperature. The discharge characteristics of the cell have been studied at different currents, and the cell remained stable for more than 15 h for low current (~0.03mA), thus making it suitable for low current density applications.
