Abstract
Ion conduction and solid state polymer battery studies of a new K+ ion conducting nanocomposite polymer electrolytes (NCPEs): (1 − x) [80PEO:20KI] + x TiO2 where 0 ≤ x ≤ 20 wt%, are reported. NCPEs were cast using a recently developed hot-press method in place of traditional solution-cast technique. The ion conduction phenomenon have been explained with the help of some basic ionic parameters viz. ionic conductivity (σ), ionic mobility (μ), mobile ion concentration (n) values and various theoretical models. The ionic transference number (tion) of optimum conducting composition of NCPE was also determined with the help of Transient Ionic Current (TIC) technique. The temperature dependent conductivity studies of NCPE OCC have been done and activation energy (Ea) value was determined by using log σ − 1/T Arrhenius plot. Solid state polymer battery was fabricated using the NCPE OCC as an electrolyte and studied their cell performances.
