Effect of TiO2 nanofiller on structural properties of PVP-CH3COOK based solid polymer electrolytes

Abstract

Nanocomposite solid polymer electrolytes have been prepared by doping TiO2 nanofiller with different wt% compositions of PVP-CH3COOK by solution cast technique. Chemical complex nature of the dopant ions was confirmed by Raman studies. DC ionic conductivity measurements of the prepared nanocomposite films were performed by lab made conductivity four probe method. From the measurement, the maximum ionic conductivity was found to be 2.01×10−3 S/cm at 373 K for the composition 60PVP:40 CH3COOK: TiO2 (1 wt %). Using the prepared nanocomposite polymer electrolytes, a solid state battery was fabricated and the discharge characteristics were studied.The original version of this article supplied to AIP Publishing contained typographical errors in the abstract paragraph. The following statement is incorrect, “the maximum ionic conductivity was found to be 2.01x10-3 S/cm at 373 K for the composition 60PVP:40 CH3COOK: TiO2 (1 wt%).” These errors are addressed and corrected below:"The maximum ionic conductivity was found to be 1.32x10-4 S/cm at 373 K for the composition 60PVP:40 CH3COOK: TiO2 (0.5 wt%)." This correction is applicable to all parts of the article.
