Abstract:

This report presents an investigation on the development of composite electrolytes for lithium batteries. The investigation covers a diverse range of composite electrolyte compositions and reveals that the incorporation of a ceramic component in a polymer matrix leads to enhanced conductivity. The conductivity enhancement depends upon the weight fraction of the ceramic phase, annealing parameters, nature of polymer-ceramic system, and temperature. The roles of ceramic additives are to depress the polyethylene oxide PEO melting temperature and retard kinetics of its crystallization. A resistivity relaxation or conductivity enhancement below the melting temperature of PEO occurs, which appears to be a characteristic of these electrolytes and related to an interaction of dipoles associated with polymer chain and ceramic particles.
