Magnesium May Soon Be Commonplace in EV Batteries
Electric vehicles could be getting a new battery ingredient in the coming years, as carmakers look beyond lithium toward a cheaper, more abundant alternative: magnesium. Lithium earned its dominant role in EV batteries for good reason, offering high energy density, a light structure and quick charging that suits modern driving needs. But the metal is running into supply problems that are hard to ignore. Bringing a new lithium mine into production takes between 16 and 18 years on average, once permitting, exploration rights, and financing are accounted for. The extraction process itself isn't gentle either, with hard rock mining generating…
