Conductive polymers are promising candidates as pseudocapacitive materials owing to their good conductivity and reversible redox reactions during charging/discharging, but they are mostly applied as cathode materials while rarely studied as anode materials for AFSCs. Recently, Wang et al. synthesized 150 WO₃@PPy nanowires on carbon fibers as the anode and grew Co(OH)₂ nanowires on carbon fabric as the cathode for AFSC device. The as‐fabricated AFSC device exhibited apparent pseudocapacitive behavior within a stable potential range of 0–1.6 V. The maximum volumetric capacitance of 2.8 F cm⁻³ was achieved at a scan rate of 20 mV s⁻¹. Moreover, the asymmetric supercapacitor (ASC) device delivered an energy density as high as 1.03 mWh cm⁻³.
