Stretchable, ‘Jelly’ Batteries Could Transform Wearables and Brain Implants

Two research teams have independently developed flexible batteries that can be stretched and deformed without losing functionality, potentially revolutionizing power sources for wearable technology and biomedical implants. A team from Nanjing University in China created a lithium-ion battery that can stretch up to 5,000 percent of its original length. The researchers said it opens up “a new avenue for the development of stretchable energy storage devices.” According to a report from the American...
