A Self-Healing Crease-Free Supramolecular All-Polymer Supercapacitor.

ABSTRACT: While traditional three-layer structure supercapacitors are under mechanical manipulations, the high-stress region concentrates, inevitably causing persistent structural problems including interlayer slippage, crease formation, and delamination of the electrode-electrolyte interface. Toward this, an all-polymeric, all-elastic and non-laminated supercapacitor with high mechanical reliability and excellent electrochemical performance is developed. Specifically, a polypyrrole electrode layer is in situ integrated into a silk fibroin-based elastic supramolecular hydrogel film with extensive hydrogen and covalent bonds, where a non-laminate device is realized with structural elasticity at the device level. The non-laminate configuration can avoid slippage and delamination, while the elasticity
