This paper investigates the Nano Composite Gel Polymer Electrolyte (NCGPEs) based on nanofillers Zirconium dioxide (ZrO₂), Polyacrylonitrile (PAN), and Ammonium triflate or Ammonium trifluoro methane sulfonate (NH₄CF₃SO₄) doped at various wt% ratios prepared with the help of the solution casting technique. The better amorphous nature observed for the 70 PAN:30 NH₄CF₃SO₄ composition with the addition of 1-4 wt% of ZrO₂ nanofillers and structural complexation studies of NCGPEs were confirmed by the X-ray Diffraction (XRD) technique. The microstructural studies and particle size can be revealed by the Scanning Electron Microscopy (SEM) technique. DC conductivity studies reveal the ionic conductivity performance on the effect of temperature and composition wt% of nanopowder. The ionic conductivity studies were observed for 70PAN:30NH₄CF₃SO₄ with nanopowder ZrO₂ concentrations ranging from 1-4 wt%. The sample containing 3% ZrO₂ exhibits the highest conductivity order of 4.20 x 10^-4 S cm^-1 at room temperature (303K) and 4.65 x 10^-3 S cm^-1 at 373 K. The cell parameters like open-circuit voltage, short-circuit current, energy density, and power density were perfectly determined, which were useful to explain electrochemical cell behavior.
