Abstract Despite the ever‐growing interest in micro‐supercapacitors (MSCs) as a promising power source for microelectronics, their low areal energy density has plagued practical applications.

Abstract Two‐dimensional (2D) transition metal carbonitrides/nitrides (MXene) materials have proven to be promising alternatives as novel capacitor‐type electrodes for aqueous Zn‐ion hybrid microsupercapacitors (ZHMSCs). However, during self‐assembly processes, serious restacking between 2D MXene nanosheets induced by strong van der Waals forces makes ion transport channels narrow within the compact film electrodes, which would result in poor energy output of ZHMSCs. Herein, interlayer channel engineering is designed intercalating bacterial cellulose (BC) interlayers develop MXene/BC with fast contrast pure electrodes. Benefiting from anion intercalation/deintercalation on cathode and reversible Zn stripping/plating foil anode, fabricated ZHMSCs exhibit wide working potential windows (1.36 V), high areal capacitance (404 mF cm −2 ), landmark density (94 µWh at 1 mA ). The developed are much higher than those based (239 /57 Besides, can perform more 10,000 cycles, showing outstanding capacity retention.

In this study, we report the preparation of a highly conductive metal–organic framework-derived carbon nanocomposite material with excellent electrochemical activity through simple surface coating carbonized-ZIF-8 (C-ZIF-8) poly(3,4-ethylenedioxythiophene)–poly(styrenesulfonate) (PEDOT–PSS). X-ray diffraction results indicate successful transformation crystalline ZIF-8 to amorphous during carbonization at 850 °C.
