Researchers have designed a working prototype of a lithium metal battery equipped with a built-in fire extinguisher, which is activated if the battery overheats.
Lithium metal batteries are currently in limited use but have huge potential because they can store ten times as much energy as lithium-ion batteries. They deliver high energy density, which means they can store large amounts of energy relative to their size. This makes them ideal for electric vehicles, portable electronics and plenty of other energy-hungry devices.
