When analyzed in lithium-sulfur batteries, these sulfur-carbon composites show high specific capacities of 1100 mAh g-1 at a low C-rate of 0.1 C and above 500 mAh g-1 at a high rate of 2 C for sulfur contents in the range of 50-80 wt%. Remarkably, the composites with 51-65 wt% S can still provide above 400 mAh g-1 at an ultra-fast rate of 4 C (where a charge and discharge cycle takes only ten minutes). The good rate capability and sulfur utilization was additionally assessed for cathodes with a high sulfur content (65-74%) and a high sul
