Contorting batteries: Charging makes nano-sized electrodes swell, elongate and spiral

New high-resolution images of electrode wires made from materials used in rechargeable lithium ion batteries shows them contorting as they become charged with electricity. The thin, nano-sized wires writhe and fatten as lithium ions flow in during charging. The work suggests how rechargeable batteries eventually give out and might offer insights for building better batteries.
