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 100degreesC to 60degreesC (close to the crystallization temperature of PEO).

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 100degreesC to 60degreesC (close to the crystallization temperature of PEO).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
