UH, Toyota researchers develop new cathode and electrolyte for high-power Mg battery rivaling Li-ion

Green Car Congress

Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered. Magnesium ions hold twice the charge of lithium, while having a similar ionic radius. —Dong et al.
