水系储能技术，包括水系超级电容器和水系电池，由于其广泛的应用潜力而引起了广泛的研究兴趣。水基电解质使水系储能装置具有快速充电能力、高功率密度、环境友好、低成本和大规模制造等优势。为了提高水系储能装置的性能，人们高度重视先进电极材料的开发。在这方面，范德华（vdW）层状含过渡金属化合物（LTMC）由于其高理论比容量和结构工程的多功能可能性而受到关注。本综述重点介绍了最近开发的 LTMC 在水储能应用中的结构工程策略。我们特别努力强调 LTMC 的工程 vdW 结构与其储能行为之间的相关性。最后，我们对该领域未来的挑战进行了展望，这有望激发人们对基于 LTMC 的水储能设备的更多探索。
Aqueous energy storage technologies, including aqueous supercapacitors and aqueous batteries, have attracted extensive research interest owing to their great potential for diverse applications. Water-based electrolytes enable aqueous energy storage devices with advantageous features, such as fast charging capability, high power density, eco-friendliness, low cost, and large-scale manufacturing. The development of advanced electrode materials is highly pursued to improve the performance of aqueous energy storage devices. In this regard, van der Waals (vdW) layered transition metal-containing compounds (LTMCs) have been brought into the spotlight due to their high theoretical specific capacity and versatile possibilities for structure engineering. This review highlights the recently developed structure engineering strategies for LTMCs in the applications of aqueous energy storage. Particular efforts are made to emphasize the correlation between the engineered vdW structure of LTMCs and their energy storage behaviours. Lastly, we provide an outlook about the future challenges in this field, which will hopefully inspire more exploration on LTMC-based aqueous energy storage devices.
