Abstract

Room-temperature sodium–sulfur (RT Na–S) batteries have been regarded as promising energy storage technologies in grid-scale stationary energy storage systems due to their low cost, natural abundance, and high-energy density. However, the practical application of RT Na–S batteries is hindered by low reversible capacity and unsatisfying long-cycling performance arising from the severe shuttle effect and sluggish S redox kinetics. This review provides an overview of recent efforts for the optimization strategies of the electronic structure of catalysts via catalyst engineering to enhance the adsorption and catalytic activity toward soluble long-chain sodium polysulfides (NaPSs). Finally, the current challenges and prospects for further optimization strategies of catalysts, understanding catalysis and structural evolution mechanism, and achieving practical applications are highlighted to meet the commercial requirements of RT Na–S batteries.

室温钠硫电池电催化剂的结构调控

室温钠硫（RT Na-S）电池因其低成本、天然丰度和高能量密度而被认为是电网规模固定式储能系统中有前途的储能技术。然而，由于严重的穿梭效应和缓慢的S氧化还原动力学，RT Na-S电池的可逆容量低，长循环性能不理想，阻碍了其实际应用。本文综述了近年来通过催化剂工程优化催化剂电子结构以提高对可溶性长链多硫化钠（NaPSs）的吸附和催化活性的研究进展。最后，强调了催化剂进一步优化策略、了解催化和结构演化机制以及实现实际应用的挑战和前景，以满足RT Na-S电池的商业化要求。图形抽象
