• • Specific capacities of conducting polymers were measured via galvanostatic charge-discharge at multiple mass-normalized current densities, enabling rate capability assessment; the dataset includes 490 files (266 MB) for comprehensive comparison.
• • Monomer functional groups (amino/imino, hydroxyl/carbonyl) directly influence redox activity and ion interaction, as evidenced by the inclusion of monomers like 1,10-phenanthroline and s-triazine; this structural variation is critical for optimizing charge storage.
• • Electrolyte composition (e.g., H2SO4, ZnSO4, KOH) significantly affects specific capacity and cycling stability, as the dataset compares performance across five aqueous electrolytes, guiding electrolyte selection for practical devices.
• • Electropolymerization allows controlled polymer loading and morphology, which are essential for achieving high specific capacity and stability; the dataset provides experimental data to correlate synthesis conditions with performance.
