英文摘要	MXenes are emerging as a very promising electrode material of high-performance micro-supercapacitors (MSCs) for microscale electronics. However, MXene based MSCs (M-MSCs) reported so far exhibit low areal (10 W h cm(-2)) and volumetric (20 mW h cm(-3)) energy densities due to their narrow working voltage in aqueous systems (0.6-1.0 V). Herein, we report for the first time the construction of high-voltage and high-energy flexible ionogel-based M-MSCs with interdigital microelectrodes of ionic liquid pre-intercalated MXene films. Benefitting from the pre-intercalation of ionic liquid, the as-fabricated M-MSCs, working at 3 V in 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIMBF4), exhibited high areal and volumetric energy densities of 13.9 W h cm(-2) and 43.7 mW h cm(-3), respectively, both of which are among the highest values for the reported M-MSCs. Moreover, all-solid-state M-MSCs using ionogel electrolytes displayed exceptional flexibility without capacitance loss under various deformation conditions and seamless integration free of metal-based interconnections for boosting voltage output. Therefore, such high-energy M-MSCs hold great potential for direct integration of flexible and miniature electronics.
