Lithium-ion batteries face toxicity, resource limits, and fire risk from thermal runaway, triggered by dendrite-induced internal shorts. Sodium-ion batteries remain flammable, toxic, and prone to dendrites. Magnesium is abundant, low-cost, and inherently safer. Its main historical failure mode is anode passivation: insulating layers block ion transport and stop the cell, rather than dendrite shorts and thermal runaway. Without intervention, Mg anodes develop overpotentials of 1–3 V or more that grow and cause cell failure. We are developing two rechargeable Mg chemistries: a high-voltage Mg-ion cell as a practical alternative to LFP and sodium-ion, and an anhydrous Mg-O₂ cell for high-energy-density stationary storage.
