In this paper, uniformly transition metal oxide (MoO3) nanosheets were electrochemically deposited on flexible carbon cloth (CC), and then conductive polyaniline (PANI) was orderly wrapped around their surface by electrochemical polymerization. The morphology and structure of as‐obtained self‐supported PANI/MoO3/CC electrode were investigated by FTIR, X‐ray diffraction, Raman, scanning electron microscope (SEM), transmission electron microscopy (TEM), and X‐ray photoelectron spectroscopy measurements in detail. Among all PANI/MoO3/CC electrode, the self‐supported PMC‐3 (deposition time of 300 s) has high specific capacitance of 841.6 F g−1 at current density of 0.5 A g−1 in the three‐electrode system, having specific capacitance of 595.7 F g−1 even at 10 A g−1. Novelty, the as‐assembled symmetrical capacitor is flexible and convenient with power density of 199.93 W kg−1 at the energy density of 9.69 Wh kg−1 and the energy density of 3.88 Wh kg−1 at power density of 4000 W kg−1. Thus, the electrochemical properties of the self‐supported PANI/MoO3/CC electrode were significantly improved, and the self‐supported electrodes are more competitive than other materials in practical application of clean energy storage systems.

Composite materials have occupied a reliable position in electrochemical energy storage and conversion due to their double electric layer and pseudocapacitance. In this work, a leaf‐like heterostructure composite, obtained by peeling – carbonizing – in situ sulfuration/oxidation approach for the first time, is investigated as electrode material for electrochemical capacitance behavior. The thin and highly active transition metal WS2 acts as an energetic “blade” to trap free ions, which are then transported across the material through a strong “tendon skeleton” WO3. The derived carbon PPC with a large aspect ratio holds up the overall leaf structure, also as a “warehouse” for ion storage, thus enhancing the conductivity and wettability of the material. The above three (WS2+WO3+PPC) synergistically provide outstanding double‐layer capacitance and pseudocapacitance. In particular, the vacancy defects, constructed at the heterogenous interface from WS2‐WO3 in situ growth, can still achieve superior ion absorption/desorption ability even under large current density and high concentration brackish solution.
