We introduced the concept of a novel hybrid faradaic structure as a mechanism to improve the performance of biomass-derived carbon-based supercapacitors (SCs). Organic-inorganic hybrid composition, nanostructures, porosity, surface area and active redox reactions were carefully designed. We reported the facile, cost-effective and environmentally friendly fabrication of pure lignin carbon nanofibers (LCNFs) incorporated with flower-like, multi-metal and intrinsically capacitive (Ni-Co@MnO₂) nanoparticles in a flexible and binder-free electrode for SCs by the electrospinning technique using various electrolytes (1 M Na₂SO₄, 0.5 M KI and 1 M Na₂SO₄ +0.5 M KI). Mechanically robust LCNFs were used as a free-standing electrode and characterized for electrochemical performance using a two-electrode system in a Swagelok cell. Specific capacitance of the LCNFs in 1 M Na₂SO₄ electrolyte (current density 0.1 A …
