• Recent advances in Ti 3 C 2 T x MXenes synthesis methods were reviewed. • MXene-based composites and hybrids for energy-related applications were summarized. • The current challenges and future perspectives of the MXene-based nanomaterials in energy-related applications were provided. This review explores the potential of MXenes, a novel class of two-dimensional (2D) materials, in advancing energy storage and conservation technologies. MXenes exhibit exceptional physicochemical properties, including a high specific surface area (∼390 m² g⁻¹ for MXene@PPy-800), outstanding electrical conductivity, and robust chemical stability, making them ideal for energy-related applications. In supercapacitors, MXene-based electrodes have demonstrated capacitances exceeding 700 F g⁻¹ at 1 mV s⁻¹, with retention of over 90 % of their initial performance after 10,000 charge/discharge cycles. For lithium-ion batteries, MXenes achieve theoretical capacities ranging from 390 to 600 mAh g⁻¹, depending on the type of MXene material, with experimental reversible capacities often exceeding 400 mAh g⁻¹ at 1C rates and high cycling stability. This review synthesizes recent research efforts on the synthesis, structural characterization, and integration of MXenes into energy storage systems. Findings highlight their versatility as electrode materials for supercapacitors, lithium-ion batteries, and fuel cells, as well as their catalytic potential in solar energy conversion. Despite these advancements, ...
