TOPIC: Composite All-Solid-State Supercapacitors for Structural Energy Storage Applications ABSTRACT: Increasing reliance on electronic devices and vehicles has generated the need for better power supply systems to meet the demands of the user, be it a phone's battery life or a vehicle's range. To better utilize the mass of these systems development of multi-functional composites that store electrical energy and provide structural support simultaneously is needed. Composites structural supercapacitors are promising candidates with their high power density, high cyclability, and safety. This work first examines the creation of a new all-solid-state polymer electrolyte that outperforms previous reports in terms of electrochemical interface and mechanical stiffness, and then elaborates the composite supercapacitor device made out of it. The solid electrolytes in this study rely on the formation of a solid solution of thermoplastic polymers and lithium salts, which can have their properties altered after exposure to humidity. It was observed that altering the salt used, the amount of salt in the solution, the humidity the electrolyte was exposed to all had a significant effect on both its electrochemical and mechanical performance. Through the alteration of these three factors, the best sample tested showed the greatest interfacial capacitance and the highest flexural modulus of electrolytes reported in the literature. The creation of a fully functional composite structural supercapacitor composed of our solid electrolyte, carbon fiber electrodes, and a glass fiber separator is covered. Using the new solid electrolyte, the process for the creation of the multi-functional composite in lab scale was created, and the electrochemical properties of the composite were characterized. These results lay the foundation for the future development of large-scale, practical structural supercapacitors.
