ION-CONDUCTING GEL POLYMER ELECTROLYTE BASED ON POLY (ACRYLONITRILE) COMPLEXED WITH (NaF + ZrO2): APPLICATION AS AN ELECTROCHEMICAL CELL

Abstract

Gel polymer electrolyte films of high conductivity were prepared using Poly acrylonitrile (PAN) complexed with Sodium Fluoride Salt (NaF) and ZrO2 nano fillers. These films were characterized like EDS Spectroscopy, UV-Vis Spectroscopy, DSC, Tensile test, and Discharge Studies measurements have been performed to characterize the polymer electrolytes. The DSC result shows that varying of melting point with increase in salt concentration. The effects of ceramic filler (ZrO2) on the conductivity of the Gel polymer electrolytes were studied. The high conductivity has been observed for 4 wt% of ZrO2 at room temperature (303 K) is about 3.69 x 10 -4 S/cm and 4.96 x 10 -3 S/cm at 373K. The prepared thick films and found to be freestanding, translucent and stretchy with good mechanical strength. The electrochemical cell has been fabricated with the configuration of Na/PAN: NaF(70:30)/Cathode(I2+C+Electrolyte+ ZrO2)and discharge characteristics were studied under the constant load of 100kΩ various cell parameters such as open-circuit voltage (OCV),short circuit current (SCC),energy density, and power density has been calculated.
