Magnesium Batteries

The potential for rechargeable magnesium batteries is hugely exciting, a truly disruptive technology. Properly constructed, Magnesium (Mg) batteries have a better energy density than lithium batteries, offering superior output at lower weight. Component cost and availability is also superior to rechargeable lithium battery components, e.g. cobalt, with positive implications for energy security.

Magnesium can be harvested from seawater if necessary. aims to become a key platform for promoting these emerging energy technologies.

Advances in surface preparation of magnesium electrodes, and new developments with electrolytes and anodes, offer great opportunity. European research very much recognizes the potential, with the European Magnesium Interactive Battery Community (E-MAGIC) as a leading light (reported as predominantly guided by Spanish / Israeli partners). Tough competition is also already developing from other major players including the US Department of Energy, IBM, assorted transnational consortia (example link), and Asian producers now heavily invested in lithium battery technology.

We've entered the decade of Magnesium Batteries (Mg Batteries)
