Description
Summary:The development of a sustainable ion-conducting solid electrolyte is an intense area of research because of its potential application in all-solid-state batteries. In the present work, ion-conducting electrolyte membranes based on water-soluble biopolymer sodium alginate and sodium perchlorate (NaClO 4 ) are prepared and analyzed. The complexation between NaClO 4 and the sodium alginate biopolymer is well established by Fourier transform infrared spectroscopy (FTIR) analysis. The inclusion and the impact of NaClO 4 concentration producing changes in the crystalline/amorphous nature of the membrane is recognized by the X-ray diffraction (XRD) technique. The thermal analysis by differential scanning calorimetry (DSC) reveals the changes in glass transition temperature ( T g ) for various sodium alginate/NaClO 4 compositions. The membrane with 60 wt% NaClO 4 :40 wt% sodium alginate exhibits maximum ion conductivity of 2.291 × 10 –3 S cm −1 at room temperature possessing a transference number of 0.96 and a potential window of 3.4 V. An all-solid-state primary battery has been constructed which is found to manifest an open-circuit potential of 3.14 V. The present investigation is very appropriate and promising for utilizing the prepared biopolymer membranes for the application of the sodium-ion battery.
