Through a bio-inspired origami design of electrode material structure, a high-density foldable flexible lithium-ion battery is proposed, which conforms to both complex deformation and high energy density, and may be tailored into any shape and fit into any space. The one-piece material structure serves as both structural and energy storage components, which may extend battery life effectively.
The development and industrial application of flexible electronics is limited by the corresponding technical constraints, especially the batteries. Currently, the lack of deformable power supplies is a serious bottleneck in the practical deployment of flexible electronics.
