Abstract Scope |
Structural supercapacitors hold the promise to significantly expand the energy capacity of a system by integrating load-bearing and energy-storage functions in a multi-functional structure, resulting in weight savings and safety improvements. Here we examined the integration of redox polymers into supercapacitor structures to serve as energy supplies that will be useful for untethered robots and general wireless electronics. A new Faradaic electrode material based on a conjugated polymer enhanced charge delocalization and thus improved stability dramatically. We tuned the UV epoxy resin with a gradient configuration to optimize it as a solid polymer electrolyte, to reinforce mechanical strength and optimize ionic conductivity at the same time. The gradient design enabled the structural supercapacitors to reach state-of-the-art performance and offered the critical benefit of long cycle life. Finally, the structural supercapacitor was made into the hull of a model boat to demonstrate its multifunctionality. |
