A rechargeable non-aqueous Mg–O 2 battery based on magnesium peroxide chemistry
Nature Chemistry, Published online: 03 July 2026; doi:10.1038/s41557-026-02199-2 Rechargeable magnesium–oxygen batteries could offer high energy density, but poor reversibility has limited their development. Now it has been shown that tailoring the Mg2+ solvation environment enables reversible magnesium peroxide chemistry and stable cycling in a non-aqueous
