Abstract: With the rapid expanse and progress of flexible/wearable electronics, it is highly desirable to develop flexible/stretchable power sources, as it is a key technique for the realization of fully flexible integrated systems. Lithium‐ion batteries (LIBs) are one of the most ideal candidates of power sources because of their attractive features of high energy density, high power density, and long cycle life. The recent progress of flexible/stretchable LIBs from the viewpoint of device structure design is reviewed herein, as the device configurations are vital for the practical applications of flexible/stretchable LIBs. The remaining challenges and future opportunities for this emerging field are also highlighted from the viewpoint of practical applications.

TL;DR: In this paper, a stretchable and self-healable hydrogel conductor was newly synthesized with all ocean biomaterials including catechol, chitosan and diatom.

TL;DR: This study presents stretchable conductors made from multiple layers of gradient assembled polyurethane (GAP) comprising gold nanoparticles capable of self-assembly under strain and a stretchable lithium-ion battery with remarkable cycle retention after 1000 cycles.
