摘要: Ordered mesoporous materials, due to its potential applications in catalysis, separation technologies, and nano-science have attracted much attention the past few years. In this work, a novel PEO-based composite polymer electrolyte by using organic–inorganic hybrid EO20PO70EO20 @ silica (P123 SBA-15) as filler has been developed. The interactions between P123 SBA-15 PEO chains are studied X-ray diffraction (XRD), differential scanning calorimeter (DSC), FT-IR techniques. effects of on electrochemical properties electrolyte, such ionic conductivity, lithium ion transference number ac impedance spectroscopy steady-state current method. experiment results show that can enhance conductivity increase which induced special topology structure hybrid, at same time. excellent transport broad stability window suggesting PEO–LiClO4/P123 be used candidate materials for batteries.
