Abstract Scope |
Superior self-healability and stretchability characteristics are key elements for the practical wide-scale adoption of beneficial personalized electronics such as portable and wearable energy storage devices. However, the current electronic devices are typically limited with small strain or stretchability, low healing efficiency and suffering from many limitations such as low device packing density, and poor stability under deformations. Here, we design an electrolyte comprising nickel flakes, EGalnPs and healable supramolecular carboxylated polyurethane (CPU), which displays all superior functions and provides a solution to the intrinsic self-healability and high stretchability problems of an energy storage device. Due to the supramolecular linkages of stronger H-bonding and weaker urethane cross-links carrying polyvalent H-bonding of CPU, self-healing can be achieved with an efficiency of 97.5%. The self-healing conductor displays an initial conductivity of 2479 S cm-1 and high stretchability of 700%, which can restore 100% stretchability even after breaking/healing with the electrical healing efficiency of 75%. |
