Abstract
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.
