Free-standing TiO2 nanowire-embedded graphene hybrid membrane for advanced Li/dissolved polysulfide batteries

Free-standing TiO2 nanowire-embedded graphene hybrid membranes have been developed for advanced Li/dissolved polysulfide batteries, which suppress polysulfide shuttling as a result of the synergistic effects of physical and chemical absorption. High capacity values of as high as 1053 mA h g−1 is retained after 200 cycles with high rate capability up to 2 C rate.
