Abstract Scope |
Structural lithium-ion batteries are capable of storing electrical energy and meeting mechanical requirements simultaneously. In this study, a coextrusion-based additive manufacturing process was applied to directly print a newly designed multifunctional structural lithium-ion battery structure with continuous carbon fibers. Individually coated carbon fiber tows as both electrolyte and separator were printed with photopolymers infused with active and conductive materials. This study demonstrated that the proposed printing processes successfully printed various types of multifunctional composites with compliant fiber-reinforced structures, circuit-imbedded composites, and carbon fiber structural batteries. Both mechanical properties as a function of structural components and electrical properties were characterized and investigated for the additively fabricated multifunctional structures. The printed structural batteries showed the promising results with decent battery capacities and strong mechanical strength. In particular, the printed multifunctional batteries were demonstrated with great potentials in the efficient use of the structural battery materials and thus significant weight reduction. |
