We’re so used to having our everyday devices powered by lithium-ion batteries that sometimes it’s hard to imagine using anything else. But there are plenty of teams working on alternatives like lithium-airsodium-ionlithium-metal and aluminum-ion designs that may help solve some of the drawbacks of lithium-ion batteries. The latest, an aqueous hybrid capacitor, is stable, safe and boasts high energy and power densities, recharging in as little as 20 seconds. read more
