Figure 14. Schematic and electrical performance diagrams of MXene/ANF composite membrane. (A) Schematic diagram of composite membrane with CNFs intercalated between the layers of the MXene. (B) Electrical performance diagram of composite membrane, in which the power density increases at first and then decreases with increasing external resistance and the current density decreases with increasing external resistance.
