| Abstract: | A study of the electrochemical properties of a PEO-based polymer electrolyte with nanometric ZrO2 as ceramic filler has been carried out in order to confirm an earlier reported model dealing with the role of ceramic fillers
within PEO-based polymer electrolytes as components that enhance such properties as conductivity, lithium transference number,
compatibility with lithium metal electrodes and cyclability. A prototype of a lithium polymer battery, based on a membrane
made from a nanocomposite polymer electrolyte doped with ZrO2, utilizing LiFePO4 + 1%Ag as cathode, has been assembled and galvanostatically cycled, resulting in excellent performance at temperatures ranging
from 100 °C to 60 °C (close to the crystallization temperature of PEO). |
