Ion Transport and Lithium Battery Characteristics of a Novel Composite Electrolyte Based on PEO Complexed with Lithium Salt

摘要

All-solid-state composite polymer electrolyte is a multiphase material that adopted an organic polymer as the main matrix. Performance improvement of electrolyte materials can be achieved by complexation between functional groups from the polymer molecular chain and the ions and, by adjusting the component and proportion of polymer and modified filler. This manuscript presents a new idea for preparation composite polymer electrolyte based on the poly(ethylene oxide). We use scanning electron microscopy (SEM), AC impedance measurements etc. to character the polymer electrolyte and their properties. We observed a very large improvement of ion conductivity by adding appropriate content of dropping fillers.
