Abstract Rechargeable magnesium batteries (RMBs) have attracted extensive attention due to the high volumetric capacity and natural abundance of (Mg) metal anode. However, Mg anode in ether‐based electrolyte systems often suffers from surface passivation, leading irreversible plating/stripping behavior Mg. In this work, for first time, an effective strategy is proposed modify by situ alloy formation using a chlorine‐free organic compound, triphenyl bismuth (TPB). Through electrochemical reduction, Mg‐Bi forms uniformly on surface, providing abundant nucleation sites Mg, allowing smooth stable deposition suppressing occurrence short circuits. 1,2‐dimethoxyethane (DME)‐based system, addition TPB significantly improves performance anode, enabling cycling up 170 h at low overpotential. Similarly, tetraethylene glycol dimethyl ether (G4) excellent observed, achieving 240 h. This work confirms feasibility additives improve interface provides new possibilities enhancing practical applications RMBs.
