The future of solid-state batteries could be 3D-printed

The race to create a solid-state battery that could compete with today's lithium-ion cells is heating up. Lithium-ion batteries are everywhere: in your phone, car, camera, and more. Since their debut in the 1990s, they've become a leader in energy storage. But they have one major flaw: safety.
