Investigation of Swelling Phenomena in Poly(ethylene oxide)-Based Polymer Electrolytes:

Abstract

The application and the performance of a new type of poly(ethylene oxide) (PEO)-based gel electrolyte membrane in lithium-ion battery systems are presented and discussed. The compatibility of this PEO-based gel membrane toward composite graphite-based anode and -based cathode films, respectively, is first evaluated. Laminated, gel-type, graphite/ lithium-ion prototypes are assembled using the PEO membrane as an electrolyte separator. The cycling performances of these prototypes are reported and discussed. © 2003 The Electrochemical Society. All rights reserved.
