Extrinsic pseudocapacitance of a vanadium carbide MXene-poly(3,4-ethylenedioxythiophene) heterostructure
In this work, we report on inducing redox charge storage of vanadium carbide MXene (V<sub>2</sub>CT<sub><i>x</i></sub>) <i>via</i> interfacial growth of poly(3,4-ethylenedioxythiophene) (PEDOT). The reversible calciation capacity of V<sub>2</sub>CT<sub><i>x</i></sub> MXene is enhanced by three times with extended anodic stability after electrochemical polymerization of PEDOT. Synergistically, PEDOT coating suppresses the water activity while enabling the optimal flux of Ca<sup>2+</sup> ions across V<sub>2</sub>CT<sub><i>x</i></sub> MXene interlayer spaces.
