The Lithium Electrode Interface: A Crucial Aspect in Polymer Batteries

Abstract

AbstractRechargeable, polymer lithium batteries are today considered as very promising advanced power sources for electric vehicle and/or consumer electronics. Many polymer electrolytes, some of which having very high ambient temperature conductivity, have been developed and characterized. However, very little attention has been so far dedicated to the study of the characteristics of the lithium electrode interface. Since the clarification of the interfacial phenomena is crucial in assessing the effective impact of polymer batteries, we have undertaken a detailed investigation of the Li passivation processes in most relevant electrolyte media and in this work we report results obtained in highly conductive cells using electrolytes formed by the immobilization of lithium solvates in polymer networks.
