Researchers built silver–zinc batteries that can bend and stretch—meaning they could be more elegantly integrated into future wearable devices. Christopher Intagliata reports.

The flat lithium ion batteries that power smartwatches are built by stacking the battery components: positive and negative electrodes, current collectors and a separator. It's akin to piling up sheets of paper—you get a stack that you can bend or roll—but you can't stretch it.
