Nanowerk  March 25, 2022 Researchers in South Korea have developed a fully stretchable lithium-ion battery system using stretchable electrode. It acquires intrinsic stretchability and improved interfacial adhesion with the active materials via a functionalized physically cross-linked organogel as a stretchable binder and separator. The stretchable current collectors are fabricated in the form of nanocomposites consisting of a matrix with excellent barrier properties without swelling in organic electrolytes and nanostructure-controlled multimodal conductive fillers. They demonstrated several types of stretchable lithium-ion batteries that reliably operated under various stretch deformations with capacity and rate capability comparable with a nonstretchable batteries even under high […]
