Popis: Highlights MVOH/rGO cathode with dual defect of Mg2+ pre-intercalation defect (P-Mgd) and surface oxygen defect (Od) is prepared. The dual defect of Od and P-Mgd in MVOH/rGO lamellar structure effectively enhances Mg2+ migration kinetics, structural stability, and electronic conductivity. The Mg foil//MVOH/rGO full cell achieves an ultralong lifespan of 850 cycles at 0.1 A g−1 and powers an orange light-emitting diode.
