Here are described core— shell nanoparticles comprising a porous metal oxide core of formula M y O x , a shell layer comprising TiO 2 and elemental sulfur (S 8 ), as an electrochemically active material, incorporated into the pores of the porous metal oxide core, their use in electrode materials as well as their methods of preparation. In a preferred embodiment, the porous metal oxide core is manganese oxide (MnO) and the elemental sulfur is incorporated into the pores of the porous metal oxide core through a melt diffusion process. Also described are composite materials, electrode materials, electrodes, and electrochemical cells comprising the core— shell nanoparticles and their use in lithium sulfur batteries. |
