High-performance hybrid supercapacitor-immobilized Wells-Dawson polyoxometalates on activated carbon electrodes.

ABSTRACT: The nanofabrication of electroactive hybrid materials for next-generation energy storage devices is becoming increasingly significant as supercapacitor (SC) technology develops rapidly. The present study utilizes activated carbon (AC) templates reinforced with Wells-Dawson polyoxotungstates (POMs) to produce nanohybrid electrodes for high-performance supercapacitors. This study analyzes Wells-Dawson polyoxotungstates (P₂W₁₈) for the first time integrated with AC, and its structural and electrochemical performances are discussed. First, the electrochemical performances of symmetric supercapacitors were characterized in an acidic aqueous electrolyte (0.5 M H₂SO₄). It was observed that a supercapacitor cell containing the 5 wt% AC-P₂W
