Abstract
We report that a sulfur/expanded graphite (EG) composite as cathode material for lithium-sulfur (Li-S) battery was synthesized by heating sublimed sulfur and EG in certain conditions. EG could be considered as micro containers and current collectors to provide sufficient electrons for the reaction between cathode materials and Li ions. Meanwhile, the rich volume of containers retains the S species at the cathode region. It suggests that the cycle ability and the utilization of S in the Li-S batteries have been improved.
