A lithium‐sulfur battery employing a high performances mesoporous hard carbon spherules‐sulfur cathode and a stable, highly conducting electrolyte is reported. The results demonstrate that the battery cycles with very high capacity, i.e., of the order of 750 mAh g −1 with excellent retention during cycling. In addition, by exploiting the high conductivity of our selected electrolyte, the battery performs very well also at low temperature, i.e., delivering a capacity of 500 mAh g −1 (S) at 0 °C for over 170 charge‐discharge cycles. We believe that these results may substantially contribute to the progress of the lithium‐sulfur battery technology.
