Carbon nanofibers functionalized by ultrasmall titanium based nanoparticles were synthesized as highperformance free-standing sulfur electrodes. With their high affinity to polysulfides and high electrical conductivity, the free-standing lithium-sulfur battery electrodes showed superior cycle retention of 85% with high reversible capacity of 1107 mA h g(-1) after 100 cycles at 1C.
