The search for lithium-ion battery alternatives has been ongoing for some time. A new EU research project has now started, which aims to support a breakthrough in magnesium batteries.

Lithium's possible replacement is composed of magnesium and sulfur, and Toyota engineering manager Jeffrey Makarewicz reportedly feels the batteries can be ready as soon as the year 2020.

Nevertheless, the team uncovered that the presence of approximately 1% magnesium ... lithium, not entirely rid of impurities, could reduce secondary battery production costs and carbon dioxide ...
