A MXene based all-solid-state microsupercapacitor with 3D interdigital electrode
2017 19th International Conference on Solid-State Sensors …, 2017•ieeexplore.ieee.org
Here we report a high capacitance all-solid-state micro supercapacitor (MSC) based on thick
interdigital electrodes of 2D Transition Metal Carbides (MXene). Ti 3 C 2 T x, one type of
MXene, features high pseudocapacity, great conductivity and cyclability. By MEMS
technologies, the 300 μm thick interdigital fingers composed of Ti 3 C 2 T x and polymer
electrolyte (PE) acts as the electrodes of a MSC, which can provide a large mass loading.

Ti 3 C 2 T x , one type of MXene, features high pseudocapacity, great conductivity and cyclability. By MEMS technologies, the 300 μm thick interdigital fingers composed of Ti 3 C 2 T x and polymer electrolyte (PE) acts as the electrodes of a MSC, which can provide a large mass loading. The high performance electrode material and thick electrode structure contribute to the MSCwith the high specific capacitance of 276 mF/cm 2 and 95% capacitance retention after 1000 cycles. Moreover, the fabrication is compatible with microfabrication technologies and the devices have the potential for the integration with other electronic devices on a chip.
