<p>Developing high-performance electrode materials is essential for supercapacitor applications. The synergistic interaction between conducting polymers and ferrite composites enhances the electrical conductivity and redox activity of the polymers, thereby improving charge transfer and capacitive performance. In this study, Polypyrrole/Ni-Mn-Co ferrite nanocomposites (NMC/PPy) with varying concentrations were synthesised via the auto-combustion method and chemical oxidative polymerisation. FTIR spectra confirmed the M‒O stretching vibrations at octahedral and tetrahedral sites, along with signature bands of Polypyrrole (PPy), confirming composite formation. XRD confirmed formation of a single-phase spinel structure with an average crystallite size of around 44.3‒45.9&#xa0;nm. SEM micrographs showed granular, spherical-like structures, indicating the incorporation of NMC into PPy. XPS confirmed the Ni²⁺/Ni³⁺, Mn²⁺/Mn³⁺, Co²⁺/Co³⁺, and Fe²⁺/Fe³⁺ states in nanocomposites. The electrical properties were studied over a wide frequency range, at different temperatures, exhibiting dielectric behaviour and thermally activated conduction, suggesting a semiconducting nature. NMC is incorporated into PPy, an AC conductivity of 3.7 × 10^‒3 S cm^‒1 for NMC/PPy-10% at 423&#xa0;K is recorded. The electrochemical investigations indicated that cyclic voltammetry (CV) displays distinct cathodic and anodic peaks, thereby corroborating a pseudo-capacitance charge storage behaviour characterised by capacitive-diffusive kinetics. The NMC/PPy-20% composite achieved the highest specific capacitance, approximately 1039.08 F g^‒1 at a current density of 1 A g^‒1. This observation aligns with the impedance findings, indicating decreased charge-transfer resistance, signifying improved electrochemical conductivity, enhanced interfacial charge transport, and superior ion diffusion. The NMC/PPy nanocomposites exhibited superior functional properties, making them suitable for multifunctional electronic applications.</p>
