When you think of a battery, you probably don’t think of something stretchy. However, batteries will need this shape-shifting quality to be incorporated into flexible electronics, which are gaining traction for wearable health monitors. Now, researchers in report a lithium-ion battery with entirely stretchable components, including an electrolyte layer that can expand by 5000%, and it retains its charge storage capacity after nearly 70 charge/discharge cycles.
This lithium-ion battery has entirely stretchable components and stable charging and discharging capacity over time. Credit: Adapted from ACS Energy Letters 2024, DOI: 10.1021/acsenergylett.4c01254To make the electrodes for the fully elastic battery, the team spread a thin film of conductive paste containing silver nanowires, carbon black, and lithium-based cathode or anode materials onto a plate.
