英文摘要: Sulfurized carbon is a promising candidate for cathode materials in practical lithium-sulfur batteries due to its high and stable capacity retention, extremely low self-discharge, and excellent safety. The main disadvantage is the relatively low sulfur content in sulfurized carbon materials. Borrowing the idea from rubber crosslinking chemistry, here we report the use of a vulcanization accelerator in carbon sulfurization. Vulcanization accelerators significantly improve sulfur content by similar to 8 wt%, which results in a remarkable increase in the discharge capacity of corresponding Li-S batteries by similar to 120 mA h g(-1) while maintaining the outstanding cycling stability and low self-discharge. The effectiveness of this approach and the wide variety of vulcanization accelerator chemistry will pave the way for sulfurized carbon materials towards practical applications in Li-S batteries.
