💡 Novelty & Significance:
P3HT is introduced as a dual-function conductive binder and redox mediator for carbon-free LiFePO₄ cathodes, eliminating Super P and calendaring. It forms an internal percolating network via electrochemical doping, enabling 2.70 g cm⁻³ packing and 1402 Wh L⁻¹ volumetric energy density—far exceeding conventional SP:PVDF systems—while maintaining cycling stability and rate capability. This integrates conductivity, redox mediation, and interfacial stabilization for next-generation high-density LFP cathodes.
