Abstract Scope |
Advancements in additive manufacturing have revolutionized the production of intricate designs, and the multifunctionality of the final item. For energy storage devices, it enables the development of shape-conformable lithium-ion batteries that also serve as a structural component. While most studies on the topic have been previously focused on addressing the compatibility of electrochemically-active material feedstocks with printers, this study rather explores a novel approach involving post-processing of 3D-printed structures manufactured via filament material extrusion and vat photopolymerization. The methodology entails designing and printing a 3D polymer substrate, followed by electrodeposition of a copper current collector and electrophoretic deposition of graphite-based electrode for its use as anode within a lithium-ion battery. This research unveils a promising method allowing battery multifunctionality: energy storage and load-bearing capabilities. Thanks to additive manufacturing, structural and shape-conformable batteries can be developed, thus enabling their seamless integration into limitless applications. |
