Abstract

Being a highly proficient material for electrochemical energy storage systems, MXene is gaining popularity. MXene pseudocapacitive charge storage system with electric double layer behaviour has improved the efficiency of supercapacitors. Furthermore, the proper interlayer spacing and distinct chemistry have enabled batteries to attain high capacity while enabling quick charge-discharge. Such breakthroughs are a result of MXene inherent characteristics, including its strong electrical conductivity, well defined layered structure, and capacity for modification, which allows it to customize electrodes to a particular purpose. Additionally, MXenes have shown their value by allowing supercapacitors and batteries to defy convention and explore the world of hybrid capacitors, micro-supercapacitors (MSCs), and batteries other than Li-ion. This article covers the MXene-based supercapcitor electrodes and difficulties associated with them. By using logical analysis, we also present several important directions for future study that could assist in resolving these issues and enabling the family of MXene materials to reach its full potential.

超级电容器的3D MXenes:现状、机遇和挑战

作为电化学储能系统的高性能材料，MXene越来越受欢迎。具有双电层特性的MXene伪电容电荷存储系统提高了超级电容器的效率。此外，适当的层间距和独特的化学性质使电池能够在实现快速充放电的同时获得高容量。这些突破是MXene固有特性的结果，包括其强大的导电性、明确的分层结构和修改能力，这使得它可以根据特定目的定制电极。此外，MXenes通过让超级电容器和电池打破常规，探索混合电容器、微型超级电容器(MSCs)和锂离子电池的世界，展示了它们的价值。本文介绍了基于mxene的超级电容器电极及其相关的困难。通过逻辑分析，我们还提出了未来研究的几个重要方向，这些方向可以帮助解决这些问题，并使MXene材料家族充分发挥其潜力。

期刊介绍： Progress in Solid State Chemistry offers critical reviews and specialized articles written by leading experts in the field, providing a comprehensive view of solid-state chemistry. It addresses the challenge of dispersed literature by offering up-to-date assessments of research progress and recent developments. Emphasis is placed on the relationship between physical properties and structural chemistry, particularly imperfections like vacancies and dislocations. The reviews published in Progress in Solid State Chemistry emphasize critical evaluation of the field, along with indications of current problems and future directions. Papers are not intended to be bibliographic in nature but rather to inform a broad range of readers in an inherently multidisciplinary field by providing expert treatises oriented both towards specialists in different areas of the solid state and towards nonspecialists. The authorship is international, and the subject matter will be of interest to chemists, materials scientists, physicists, metallurgists, crystallographers, ceramists, and engineers interested in the solid state.
