Lithium-sulfur battery system is one of the promising candidates for future power system in portable devices or electric vehicles.Li-S system exhibits theoretical capacity and energy density of 1672 mAh/g and 2600 Wh/kg, respectively.However, the insulating nature of element S and electrochemical reaction product (Li2S or Li2S2),together with the fast degradation caused by the dissolution of polysulfides remain hindrance for the practical applications of Li-S battery system.It is crucial to improve the specific capacities of sulfur cathode and the cycling stability of lithium sulfur batteries.
