Currently, Lithium batteries present the most promising solution forenergy storage in many applications, from electronic devices to electricalvehicles and electrical network power storage. Among the new battery technologies, Lithium-Sulfur batteries are attractive because since they have high capacity (1675 mAh g-1), high energy density, high efficiencyand long life cycles. [1] However, they present some disadvantages suchas low conductivity of sulfur, volume changes during lithiation / delitiation and generation of polysulfides (PS) during cycling, leading to the reduction of active material, the decreasing in the coulombicefficiency, and deterioration of cycling performance. The aim of the present work is to modified commercial separator with carbon material in order to optimize the performance and durability ofLithium-Sulfur batteries.
