This study presents a high-performance asymmetric supercapacitor (ASC) utilizing earth-abundant materials: a CZTS@rGO:PANI positive electrode and a rGO:WO3 negative electrode, both synthesized via one-step electrochemical deposition. Structural and morphological analyses confirm a synergistic, porous architecture that facilitates rapid charge transfer. In a three-electrode setup (5 M KOH), the CZTS@rGO:PANI electrode reaches an enhanced specific capacitance of 517.7 F g−1 at 4 A g−1. The assembled CZTS@rGO:PANI//rGO:WO3 ASC operates within a 1.0 V window, delivering a notable energy density of 14.8 Wh kg−1 and an exceptional power density of 1975.9 W kg−1. Furthermore, the device achieves a maximum volumetric energy density of 5.71 Wh cm−3 and a peak volumetric power density of 0.15 kW cm−3. Impressively, the device maintains 78.6% capacitance retention over 10,000 cycles, supported by a minimal charge transfer resistance (RCT) of 1.0 Ω. Kinetic analysis reveals a dominant surface-controlled mechanism with enhanced capacitive contributions at high scan rates. Diverging from low-mass laboratory models, this work employs a commercially relevant mass loading (∼10.7 mg), bridging the gap between fundamental research and industrial viability. Collectively, these results validate the ternary CZTS, PANI, and rGO configuration as an effective strategy for developing high-efficiency energy storage technologies with industrial viability.
