Meanwhile, many porous host materials are electronically insulating and require substantial carbon additives, which dilute the active mass and reduce practical capacity and kinetics. Here, we report a high\u2010performing PIB anode based on thin 2D crystals of an intrinsically conductive bismuth metal\u2013organic framework (MOF) built from \u03c0\u2010conjugated hexahydroxytriphenylene (HHTP) ligands. Electronic coupling between the HHTP ligands and Bi nodes yields markedly higher conductivity than analogous 3D carboxylate Bi\u2010MOFs. Atomically accessible Bi sites on the 2D sheets enable extensive, highly confined K\u2013Bi alloying, which drives reversible framework disassembly during potassiation and reassembly upon depotassiation, as revealed by operando X\u2010ray diffraction (XRD). The electrode delivers high reversible capacity from efficient alloying\/dealloying, complemented by ligand\u2010mediated pseudocapacitive storage at higher potentials. Confinement of the alloying reaction buffers strain and limits electrode expansion by fourfold compared with Bi powder. Bi\u2010HHTP outperforms 3D Bi\u2010MOFs and conductive Cu\u2010, Ni\u2010, and Co\u2010HHTP analogues across all tested current densities, establishing conductive Bi\u2010HHTP as a top\u2010performing MOF\u2010based anode for PIBs and providing design guidelines for future alloy\u2010type
