Batteries as they stand today are dominated by lithium-ion batteries, with lithium ions moving between the anode and cathode during charge and discharge cycles. Massive research efforts continue to improve and perfect chemistries such as lithium iron phosphate, in addition to research into solid-state batteries that would also replace flammable liquid electrolytes with solid ones. And sodium-based alternatives have made progress as researchers continue to search for viable next-generation chemicals that are cheap, energy-dense and safe.
Magnesium has long been seen as a promising alternative chemistry. Like sodium, the element or metal is abundant, nontoxic, and theoretically capable of high volumetric energy density.
However, magnesium has what chemists describe as “slow ion mobility” at room temperature, meaning it is far from being put into practical use.
