Stretchable Lithium-Ion Battery Demonstrated

US researchers have demonstrated a flexible, stretchable lithium-ion battery that can be recharged wirelessly, enabling its use in numerous applications needing flexible electronic components. Developed by Yonggang Huang, professor of civil and environmental engineering and mechanical engineering from Northwestern University and John A. Rogers, professor of materials science and engineering as well as chemistry at University of Illinois, the battery could power stretchable electronic devices such as implantable medical devices. They have demonstrated the battery powering an LED and continuing to work even when contorted in different ways. It is reportedly capable of stretching by up to 300 percent of its original size while continuing to function. The battery’s life is between eight and nine hours. The researchers plan to publish their work in Nature Communications.  (PhysOrg)(Northwestern University @ EurekAlert)
