Chemical Engineering Journal, Journal Year: 2023, Volume and Issue: 472, P. 144913 - 144913

Published: July 19, 2023

Supercapacitors, which are essential for addressing modern energy challenges, possess outstanding storage capabilities without requiring manual maintenance. However, their low density and capacity limit applicability electrode materials. Recently, two-dimensional materials (2D), particularly 2D transition metal carbonitrides (MXenes) have attracted considerable interest developing devices because of large specific surface area fast ion-transport pathways. MXenes mainly comprise a (M) layer, carbon and/or nitrogen (X) active functional groups exterior to the layer. Metallic properties M layer offer excellent pseudocapacitance characteristics, while X is characterized by abundant sites conductivity similar that graphene. Compared with conventional materials, existence various on endows them stronger hydrophilicity higher wettability in aqueous electrolytes, which, combined diverse frame structures group combinations, significantly augment devices. Therefore, it necessary summarize analyze research results MXenses. This review addresses applications supercapacitors along current challenges solutions including intercalation, doping, modification methods, heterogeneous structures. Finally, prominent contemporary trends comparatively discussed promote development this field near future.
