Multifunctional structural batteries, which combine load-bearing and energy storage, promise weight reduction and enhanced safety but face commercialization challenges due to vast design spaces and costly trial-and-error. This work accelerates the design of CF-based structural batteries impregnated with SPE using an experimentally validated framework. Finite element analysis based on computational micromechanics examines the CF/SPE interface and predicts effective properties, while a Bayesian-optimized ANN forecasts capacity under rapid degradation conditions—providing promising insights for multifunctional composite optimization.

In this work, multifunctional carbon fiber-based structural battery was fabricated in a robust scheme developing a laminated structural battery impregnated with epoxy-based solid polymer electrolyte (SPE). Informed by cure kinetics, SPE processing enhances the multifunctional performance with no fillers or additives. By analyzing the interfacial properties, SPE processing, and assembly attributes, this study propels the development of advanced multifunctional structures.

Although it is possible to enhance performance through the modification of constituents, there remains a need for a systematic design methodology scheme to streamline the commercialization of structural batteries. In this work, a bi-phasic epoxy-based solid polymer electrolyte (SPE) was developed via thermally initiated phase separation. The polymer's morphological, mechanical, and electrochemical characteristics were studied. In addition, the interfacial shear strength (IFSS) between CF/SBE was investigated via microdroplet tests.
