Abstract In this study, carbon black-polyaniline (CB@PANI) core-shell nanocomposites with varying carbon contents are synthesized and incorporated into the negative active material of lead-acid batteries. The structural characterization by FT-IR, XRD, SEM, and TEM confirmed the formation of a uniform core-shell morphology with strong interfacial interaction between PANI and CB. The electrochemical analyses, including CV, LSV, EIS, and HRPSoC cycle-life testing, revealed that the electrode containing PCB10 nanocomposite exhibited the highest specific capacitance, lowest charge-transfer resistance, and most favorable redox reversibility. Moreover, PCB10 maintained its structural integrity over prolonged cycling, achieving a cycle life 6.9 times longer than the Blank electrode.
