Potential study of biopolymer-based carboxymethylcellulose electrolytes system for solid-state battery application

This paper focused on study of potential biopolymer carboxymethylcellulose (CMC) as electrolyte system for application in solid-state battery, which was prepared via solution casting technique. The highest conducting CMC biopolymer electrolytes (BE) was achieved at 1.12x10(-4) Scm(-1) with addition of 25wt% NH4Br and was improved to 3.31x10(-3) Scm(-1) when plasticized with 8wt% EC. The solid-state battery was assembled using both systems with the configuration Zn +ZnSO4.7H(2)O // highest conducting BE // MnO2 and showed promising performance at room temperature. This work implies that the possible practical application of the present biopolymer CMC as a new invention of electrolytes system in the fabrication of electrochemical devices.
