Abstract

Nanocomposite polymer electrolytes (NCPEs) comprising poly(ethylene oxide) (PEO), barium titanate-grafted-graphene oxide (BaTiO₃-g-GO) and lithium bis(trifluoromethanesulfonyl imide) (LiTFSI) were prepared by a simple hot-press technique. An increase of two orders of magnitude in the ionic conductivity was achieved upon incorporation of BaTiO₃-g-GO in the polymeric matrix even at 0 °C. The addition of BaTiO₃-g-GO as a filler has significantly enhanced the thermal stability and mechanical integrity of the membrane. The BaTiO₃-g-GO-laden membrane was found to have better interfacial properties with a lithium metal anode than the filler-free membrane. Charge-discharge studies revealed a stable cycling profile even at 5C-rate and it was found to be superior to those reported earlier.
