A new job for an overlooked battery component

Caption

Scientists at Stanford and SLAC redesigned current conductors - thin metal foils that distribute current to and from electrodes - to make lithium-ion batteries lighter, safer and more efficient. They replaced the all-copper conductor, middle, with a layer of lightweight polymer coated in ultrathin copper (top right), and embedded fire retardant in the polymer layer to quench flames (bottom right).
