Breakthrough in Stretchable Batteries Promises Advances in Wearables and Implants

New flexible battery technologies from Nanjing University and University of Cambridge offer significant potential for medical and consumer applications.

Nanjing University developed a lithium-ion battery that can stretch up to 5,000 percent of its original length.
University of Cambridge created 'jelly batteries' inspired by electric eels, using hydrogels to maintain conductivity even when stretched.
Both technologies aim to improve the functionality and comfort of wearable and implantable devices.
The batteries can withstand significant deformation without losing performance, enhancing their potential for medical use.
Further testing and development are needed to increase charge cycle durability and ensure biocompatibility.
