Recent advances and future prospects of low-dimensional Mo2C MXene-based electrode for flexible electrochemical energy storage devices

Abstract

This paper provides an in-depth overview of the recent advances and future prospects in utilizing two-dimensional Mo₂C MXene for flexible electrochemical energy storage devices. Mo₂C MXene exhibits exceptional properties, such as high electrical conductivity, mechanical flexibility, and a large surface area, which make it a promising material for diverse energy storage applications, including lithium-ion batteries, lithium-sulfur batteries, sodium-ion batteries, and supercapacitors. The review begins by discussing the various synthesis methods and characterization techniques employed to fabricate flexible Mo₂C MXene-based composites. It then delves into detailed analyses of the electrochemical performance of these composites in different energy storage systems. The optimal temperature and duration for synthesizing flexible Mo₂C MXene materials are examined, with a focus on their influence on specific capacity, current density, and cycle life. Furthermore, the review investigates the synergistic effects of incorporating flexible Mo₂C MXene with other materials, such as graphene, carbon nanofibers, carbon nanotubes, nanowires, nanorods, and porous materials. The objective is to explore how these supporting materials can enhance flexibility and surpass existing energy storage technologies, particularly in the context of lithium-ion batteries, lithium-sulfur batteries, sodium-ion batteries, and supercapacitors. The concluding section addresses the future prospects and challenges in the field.
