Fabrication and characterization of a solid polymeric electrolyte of PAN-TiO2-LiClO4
The ionic conductivity of PAN-TiO2-LiClO4 as a function of TiO2 concentration and temperature has been reported. The electrolyte samples were prepared by solution casting technique. Their conductivity was measured using the impedance spectroscopy technique. The highest room temperature conductivity...
