Rechargeable Mg batteries promise low‐cost, safe, and high‐energy alternatives to Li‐ion batteries. However, the high polarization strength of Mg2+ leads to its strong interaction with electrode materials and electrolyte molecules, resulting in sluggish Mg2+ dissociation and diffusion as well as ins...
