Abstract

An integrated, selective interlayer structure is developed to further mitigate the diffusion of polysulfides, simply by coating the surface of a C–S cathode with a graphene/TiO2 film. It is found that the application of the graphene/TiO2 film as an interlayer enables the porous carbon nanotubes–S ca...
