TiO 2 -coated sulfur-acetylene black composite with a core-shell structure is synthesized via a simple process and investigated as a cathode for the lithium-sulfur batteries. The composite nanoparticle sizes are in the range of 50–100 nm, and the thickness of TiO 2 shell is about 10–50 nm. The compo...
