Recent novel forms of MXene as a two-dimensional lithium-ion battery material

Lithium-ion batteries are the most sustainable solutions for energy storage and are evolving enormously in terms of materials and design. Multiple efforts are reported to improve the various factors of lithium-based energy storage devices like specific density and long-life cycle with new compatible and conducive materials for electrodes. MXene is one of the most recently evolved 2D-layered materials with high specific density and conductivity. However, the operational issues of restacking, oxidation, and less number of active sites for lithium insertion lead to inadequate cycle life, thus affecting the MXene’s commercial proposition. Multiple solutions have been reported in last 14 years since its invention, out of which the last three years (2023, 2024, and 2025) have seen significant advancements of new synthesis strategies, materials, structural configurations, and long-life testing. This review provides a comparative analysis of the advancements made recently in form of hierarchical segregation (mono-transition, dual-transition, composites) supported with comparative analysis with past 14 years. The review also presents the recent novel applications of MXene in LIBs besides electrode manufacturing. The contribution of this review is the novel hierarchical one-look segregations that reveal the potential research gaps for future and will be helpful for researchers and commercial industry.
