The rapid development of miniaturized and wearable electronics has stimulated growing needs for compatible miniaturized energy storage components. Owing to their unlimited lifetime and high-power density, miniaturized electrochemical capacitors (microsupercapacitors) are considered to be an attractive solution for the development of these microelectronics, but they often depend on the choice of electrode materials and fabrication protocols for scalable production. Recently, a new family of two-dimensional transition metal carbides, carbonitride and nitrides (referred to as MXenes) has shown great promise in advanced microsupercapacitors with high energy and power densities. This was achieved thanks to the high pseudocapacitance, metallic conductivity and ease of solution processing of MXene. In this review, recent progress on MXene materials synthesis, microstructure design, and fabrication strategies of MXene microsupercapacitors are discussed, and electrochemical performance is summarized. Further, we briefly discuss the technical challenges and future directions.

小型化和可穿戴电子产品的快速发展刺激了对兼容的小型化储能组件的增长需求。由于其无限的使用寿命和高功率密度，微型化的电化学电容器（微型超级电容器）被认为是这些微电子技术发展的一种有吸引力的解决方案，但它们通常取决于电极材料的选择和可扩展生产的制造协议。最近，新型的二维过渡金属碳化物，碳氮化物和氮化物（称为MXene）在具有高能量和功率密度的先进微型超级电容器中显示出了巨大的希望。这要归功于高假电容，金属电导率和MXene的溶液加工简便性。在这篇评论中 讨论了MXene材料合成，微结构设计和MXene超级电容器制备策略的最新进展，并总结了电化学性能。此外，我们简要讨论了技术挑战和未来方向。
