Synergistically engineered B- and P-doped graphite felts as tailored asymmetric electrodes for aqueous quinone-based redox flow batteries

P and B heteroatom-doped graphite felts serve as optimized electrode materials for quinone-based AORFBs, owing to their synergistic hydrophilicity, conductivity, and specific adsorption activity towards anthraquinone and benzoquinone electrolytes.
