The widespread use of wearables and the rising need for electricity create a special potential for fiber-based mobile energy storage devices. For powering non-flat electronic devices, supercapacitor fibers with quick charge rates, prolonged cycle lifetimes, and high power densities seem to be especially well-suited. For scalable machine weavability or as an ink feedstock for 3D printing, the length of fiber-shaped supercapacitors must be comparable to traditional long-length textile fibers. But no system has yet succeeded in achieving this objective. In this talk, I will discuss a process for realizing a supercapacitor in a system-level fiber, opening the door to long, flexible energy storage fibers that are high-performing, printable, flexible, and machine-washable. This method of producing supercapacitor fibers makes use of a preform-to-fiber thermal drawing procedure in which the supercapacitor architecture and materials are integrated into a preform and drawn into arbitrary lengths of multi-material supercapacitor fiber.
