Li-conducting polymer electrolytes are fundamental materials for the development of advanced lithium secondary batteries. In general, classical polymer electrolytes (PEs) consist of organic macromolecules (e.g., polyethers) doped with inorganic salts including LiClO4 , LiPF6 , LiTFSI, among others. These PEs show good room-temperature conductivities (on the order of 10-5 - 10-6 S·cm -1 ), but low Li + transference numbers. One possibility to address this latter issue is to dope PEs with an inorganic nanofiller such as SiO2 , TiO2 or Al2O3 . As a result, both the conductivity and the transference numbers may be improved.

Abstract

Li-conducting polymer electrolytes are fundamental materials for the development of advanced lithium secondary batteries. In general, classical polymer electrolytes (PEs) consist of organic macromolecules (e.g., polyethers) doped with inorganic salts including LiClO4 , LiPF6 , LiTFSI, among others. These PEs show good room-temperature conductivities (on the order of 10-5 - 10-6 S·cm -1 ), but low Li + transference numbers. One possibility to address this latter issue is to dope PEs with an inorganic nanofiller such as SiO2 , TiO2 or Al2O3 . As a result, both the conductivity and the transference numbers may be improved.
