Conducting Carbon Black Nano‐Filler Doped Polymer Electrolyte for Electrochemical Application

Abstract

AbstractThis study provides a development of polymer electrolytes with an emphasis on their use in electrochemical devices. In present study we develop a new conducting carbon black (CB) powder dispersed into polyethylene oxide (PEO) polymer electrolyte using solution cast method. Various characterization techniques such as Impedance spectroscopy technique (EIS), Fourier transform infrared spectroscopy (FTIR), and Window stability (LSV) Linear sweep voltammetry has been studied in detail. The maximum ionic conductivity polymer electrolyte was at 0.05 wt%. of CB with σ value 1.20×10−5 S/cm. Finally the prepared CB dispersed polymer electrolyte using maximum conductivity sample is sandwiched between electrodes to fabricate an Electric double layer capacitor and Dye‐sensitized solar cell which show highest electrical capacity value of 68.5 F/gm at 5 mV/s respectively and 2.97 % efficiency shown by solar cell at 1 sun condition.
