2D transition metal carbides and nitrides (MXenes) are electrochemically active materials capable of exhibiting pseudocapacitance. Multilayer MXenes are similar to graphite, but with larger interlayer spacing and surface functionalities which allow them to readily disperse in water and undergo a range of reactions without compromising their electrical conductivity. The large interlayer spacing enables MXenes to readily intercalate large ions, and form composites with materials such as graphene, metal oxides, transition metal dichalcogenides and silicon, with which they make electrodes able to deliver exceptional capacities at high power rates over thousands of cycles. Research into MXenes for energy storage has grown exponentially since 2011, and it is now necessary, especially for readers new to the field, to review progress made in more specific areas. This critical review will therefore analyse the progress made in developing MXene‐based batteries, focusing solely on anodes developed for metal‐ion batteries such as Li‐ion, Na‐ion and K‐ion.

用于金属离子电池的基于MXene的阳极

2D过渡金属碳化物和氮化物(MXenes)是能够表现出假电容的电化学活性材料。多层MXene与石墨相似,但具有更大的层间间距和表面功能,这使它们易于分散在水中并进行一系列反应,而不会损害其导电性。较大的层间距使MXene能够轻松插入大离子,并与诸如石墨烯,金属氧化物,过渡金属二卤化物和硅等材料形成复合材料,它们使电极能够在数千次循环中以高功率速率提供出色的容量。自2011年以来,对MXene用于能量存储的研究呈指数级增长,现在有必要,特别是对于刚接触该领域的读者而言,审查在更具体领域中取得的进展。因此,本次重要的回顾将分析开发基于MXene的电池所取得的进展,并将重点仅放在为金属离子电池(如Li-ion,Na-ion和K-ion)开发的阳极上。
