In this paper we report the performances of a lithium-ion sulfur battery characterized by a polymer\udconfiguration. The cell, based on a sulfur-carbon cathode, a Li-Sn-C nanostructured anode and a\udPEO-based, polysulfide-added electrolyte, shows very good electrochemical performances in terms of\udstability and delivered capacity. The remarkable cell performances are ascribed to the mitigation of the\udcathode dissolution process due to the buffer action ensured by the polysulfide added to the polymer\udelectrolyte. This electrolyte configuration allows the achievement of a stable capacity ranging from 500 to\ud1500 mAh g-1S, depending on the cycling rate. The use of a polymer electrolyte and the replacement of the\udlithium metal with a Li-Sn-C nanostructured alloy are expected to guarantee high safety content, thus\udsuggesting the battery here studied as advanced energy storage system.
