室温碱金属硫电池由于其高容量和低固有成本而成为锂离子电池的有前途的替代品。在此，我们报告了 MXene (Ti3C2TX) 作为限制硫 (S8) 的主体，使得能够在金属硫电池中使用商业化友好的碳酸盐电解质。多层 MXene 结构为 S8 限制提供可调间距，其独特的层间间距可防止不利的多硫化物-碳酸酯反应。
Room-temperature alkali metal–sulfur batteries are promising alternatives to lithium-ion batteries because of their high capacity and low inherent cost. Herein, we report MXene (Ti3C2Tx) as a host to confine sulfur (S8), enabling the use of commercialization-friendly carbonate electrolyte in metal–sulfur batteries. The multilayer MXene structure provides tunable spacing for S8confinement, and its unique interlayer spacing prevents adverse polysulfide-carbonate reactions.
