Recently, Dr, Bi Wenchao from College of Science published a review paper titled “Synthesis, properties, and applications of MXenes and their composites for electrical energy storage” in internationally famous journal Progress in Materials Science. Dr. Bi Wenchao was the first author of the paper. Prof. Gao Guohua and Prof. Wu Guangming from Tongji University, and Prof. Cao Guozhong from University of Washington, U.S were all the corresponding authors of the paper. USST was the first unit.
With the development and utilization of new energy, energy storage systems such as supercapacitors and secondary ion batteries have drawn widespread attention. With the Maxenes, a new family of two-dimensional transition metal carbides, nitrides and carbonnitrides, have emerged as promising materials for electrical energy storage (EES) systems due to their superior properties, such as high electronic conductivity, excellent mechanical capability, and hydrophily. These properties of MXenes are closely related to their structure and surface functional groups, and directly decided and readily tailored by means of synthesis methods applied. The properties of MXenes have determining effect on the electrochemical performance of EES systems. This review begins with the intrinsic connections between properties and crystal structure, chemical composition and surface chemistry of MXenes as background. n, the effects of latest synthesis on MXenes’ properties are systematically scrutinized, including the effects of precursors, processing parameters, the etching, delaminating, and compositing strategies of MXenes. Further focus is turned to the state-of-the-art progress of MXenes and their composites acting as cathodes, anodes, current collectors, electrolyte additives, and conductive binder insupercapacitors, monovalent (Li+, Na+, K+, and halogen anion) ion batteries, and multivalent (Zn2+, Mg2+, Ca2+, and Al3+) ion batteries. The synthesis-property-application relationships in MXenes for desired EES devices are highlighted.
The critical challenges and perspectives are discussed for the future of development of MXenes in advanced supercapacitors and rechargeable batteries. The research will have profound impacts on the field of energy storage, catalysis field, optical field, and medical field.
