全球能源需求正在迅速增长，这无疑反映了基于地球丰富资源的大容量储能系统的重要性。锂离子电池用于大规模储能的实用性由于锂的来源有限及其地理分布不均而不太可能可行。由于地球上丰富的钠和钾以及涉及多电子转移的富硫电化学，钠-硫（Na-S）和钾-硫（K-S）电池是大规模储能应用的有希望的候选者。本文重点介绍了Na-S和K-S电池的基本化学组成和挑战。讨论了阴极、阳极和隔膜的设计策略，重点讨论了碳材料的利用，突出了碳在应对挑战中的关键作用。最后展望了钠硫电池和钾硫电池的发展前景。
Global energy demand is rapidly increasing, and it undoubtedly reflects the importance of high-capacity energy storage systems based on Earth's abundant resources. The practicality of lithium-ion batteries for large-scale energy storage is less likely to be viable due to the limited sources of lithium and their uneven geographical distribution. Because of the Earth's abundance of sodium and potassium as well as rich sulfur electrochemistry involving multi-electron transfer, sodium-sulfur (Na-S) and potassium-sulfur (K-S) batteries are promising candidates for large-scale energy storage applications. This review highlights the fundamental battery chemistries and challenges of Na-S and K-S batteries. It discusses the design strategies of cathode, anode, and separator with a focus on the utilization of carbon materials, highlighting the crucial role of carbon in tackling the challenges. Finally, future perspectives are provided, and plausible directions are outlined for the further advancement of Na-S and K-S batteries.
