摘　　要：室温钠硫电池具有原料(Na和S)来源丰富、成本低、极高的理论放电比容量(1672 mAh·g^(-1))等优点,被认为是极具潜力的下一代二次电池.然而,充放电过程中溶解的多硫化钠(NaPSs)的穿梭效应,以及硫物种缓慢的氧化还原动力学过程是室温钠硫(RT-Na/S)电池商业应用前需要解决的关键问题.而电化学催化的引入是解决上述问题行之有效的策略.该文从过渡金属(如Fe、Co等)电化学催化特有的角度出发,结合最新成果,分析硫反应的转化路径,并对目前评价催化性能方法进行了总结,为室温Na/S电池的实际化应用提供解决策略及研究思路.Sodium batteries have attributed significant attention,because of their abundant resources and economical production costs.Among these,room temperature sodium sulfur(RT-Na/S)batteries is a promising next-generation secondary batteries,due to the sulfur cathodes show a high theoretical discharge capacity(1672 mAh·g^(-1)).However,the challenges of the shuttle effect caused by dissolved sodium polysulfide(NaPSs)during the charging and discharging,along with the sluggish redox kinetics of sulfur species,remain pivotal obstacles requiring resolution before the widespread commercialization of RT Na/S batteries.The introduction of electrochemical catalysis is an effective strategy to solve the above issues.In this review,from the unique perspective of electrochemical catalysis of transition metals(such as Fe,Co,etc.),combined with the latest achievements,the transformation path of sulfur reaction was analyzed,and the current methods for evaluating catalytic performance were summarized,so as to provide solutions and research ideas for the practical application of RT-Na/S batteries.
