Enhanced lithium ion transference number and ionic conductivity of composite polymer electrolyte doped with organic–inorganic hybrid P123@SBA-15

A novel Poly(ethylene oxide)-based composite polymer electrolyte by using organic–inorganic hybrid EO20PO70EO20@mesoporous silica (P123@SBA-15) as the filler has been developed. The experiment results show that P123@SBA-15 can enhance the lithium ion transference number and ionic conductivity of the electrolyte, which are induced by the special topology structure of P123 in P123@SBA-15 hybrid, at the same time. The excellent lithium ion transporting properties suggesting that the composite polymer electrolyte PEO–LiClO4/P123@SBA-15 can be used as candidate electrolyte material for lithium polymer batteries.
