MXene is rising as a versatile two-dimensional material (2DM) for electrochemical energy storage devices. MXene has boosted the performance of supercapacitors thanks to its pseudocapacitive charge storage mechanism with electric double layer behavior.
The mechanism, coupled with the high electrical conductivity, equips MXene electrodes with a high-rate energy storage capability 62, 69. The specific rate ability varies with the MXene type and electrolyte choice.

Grafted MXene/polymer electrolyte for high performance solid zinc batteries with enhanced shelf life at low/high temperatures. Energy Environ. Sci. 14, 3492–3501 (2021).
The stability of MXene is correlated with the reliability of batteries and other energy storage and conversion devices employing MXenes in their components. Thus, studying the chemical degradation mechanism and the development of corresponding protection protocols that afford stable MXenes deserve more attention 190, 191, 192.
The transition metal core layers in MXene facilitate rapid electron transfer, enabling good charge storage at high rates, meanwhile the transition metal oxide-like surface provides redox active sites for pseudocapacitive charge storage. These two properties make MXene-based materials as promising electrode materials for LIBs.
