Abstract Magnesium (Mg) is a promising anode material for magnesium metal batteries (MMBs) owing to its high specific capacity, excellent safety profile, and abundant availability. However, pristine Mg anodes suffer from uneven plating/stripping surface passivation/corrosion, limiting the cycling stability of MMBs. This study introduces Bi/Mg‐based hybrid interphase protective layer on foil (denoted Bi‐Mg@Mg) through an in situ quasi‐solid–solid redox reaction by immersing bismuth oxybromide suspension. The resulting consists magnesiophilic components (Bi Bi 2 3 alloy) magnesiophobic species (MgO, MgBr , BiBr ). These synergistically enhance desolvation, nucleation, deposition kinetics, mitigate side reactions, promote uniform electric field ion flux distributions. As result, Bi‐Mg@Mg electrodes exhibit superior reversibility, maintaining stable performance over 4100 h all‐phenyl complex electrolyte 2900 Mg(TFSI) electrolyte, significantly outperforming electrodes. Furthermore, full cells paired with Mo 6 S 8 cathodes demonstrate capacities, rate capabilities, long lifespans, highlighting exceptional electrochemical anode. offers strategy developing highly reversible anodes, paving way practical long‐cycle
