Recent advancements in MXene with two-dimensional transition metal chalcogenides/oxides nanocomposites for supercapacitor application – A topical review

초록

Researchers in several sectors, including those developing energy storage systems with electrodes for supercapacitors and batteries, are fascinated by MXenes, a new class of 2D materials. Increased usage of MXene and its composites in supercapacitors has been attributed to its astonishing mechanical, electrical, optical, and electrochemical characteristics. In this article, we review and discuss recent advancements and trends in experimental studies on MXene and its composites for use in supercapacitor applications. First, we discuss several preparation methods for obtaining high-quality MXene and its composites with transition metal sulfides/oxides and bimetal sulfides/oxides. Then, we review a few critical issues that hamper the use of MXene in supercapacitor applications. These include the current drawbacks and challenges related to flexibility, internal diffusion resistance, and material oxidation of MXene-based supercapacitor electrodes. © 2024 Elsevier B.V.
