Abstract
A new, sizable family of 2D transition metal carbonitrides, carbides, and nitrides known as MXenes has attracted a lot
of attention in recent years. This is because MXenes exhibit a variety of intriguing physical, chemical, mechanical, and
electrochemical characteristics that are closely linked to the wide variety of their surface terminations and elemental
compositions. Particularly, MXenes are readily converted into composites with materials including oxides, polymers, and
CNTs, which makes it possible to modify their characteristics for a variety of uses. MXenes and MXene-based composites
have demonstrated tremendous promise in environmental applications due to their excellent reducibility, conductivity,
and biocompatibility, in addition to their well-known rise to prominence as electrode materials in the energy storage
sector. The remarkable characteristics of 2D MXene, including high conductivity, high specific surface area, and enhanced
hydrophilicity, account for the increasing prominence of its use in storage devices. In this review, we highlight the most
recent developments in the use of MXenes and MXene-based composites for electrochemical energy storage while
summarizing their synthesis and characteristics. Key attention is paid to applications in supercapacitors, batteries, and
their flexible components. Future research challenges and perspectives are also described.
