Oxidation‐Driven Enhancement of Intrinsic Properties in MXene Electrodes for High‐Performance Flexible Energy Storage

Advanced Functional Materials, EarlyView.
By employing a partial oxidation strategy, nanosized pores are introduced into MXene nanosheets. The resulting holey MXene exhibits faster ionic transport, achieving an aerial capacitance 2.5 times that of unmodified MXene electrodes, and demonstrates excellent cycling stability, retaining 91.7% of its capacitance after 10 000 cycles.
