Reduced graphene oxide (RGO) supported anatase TiO2 nanostructures were designed for sodium ion battery anode application, which were prepared by simple one-step technique spray pyrolysis, in order to inhibit the aggregation of TiO2 nanoparticles and to improve the electrochemical performance. The as-prepared TiO2-RGO nanostructured composites had high surface area, massive pores, and excellent structural...
Li2S with theoretical capacity of 1166mAhg−1 has been considered as a promising candidate for Li-S cathode as it could be paired with safer Li-free electrodes to resolve safety issues. However, the success is hindered by the nature of Li2S and corresponding reduction species, including low conductivity and the shuttling phenomenon. Herein, we simply coat graphene films directly onto the Li2S cathode,...
