Abstract Scope |
Additive manufacturing has the potential to revolutionize the fabrication of energy storage devices such as lithium-ion batteries (LIB) for portable and transportation applications. In this work, vat photopolymerization (VPP) 3D printing of a photosensitive resin, loaded with LiCoO2 positive electrode active material for a classical LIB, was performed using Direct Light Processing (DLP) and Stereolithography (SLA). To overcome the challenges related to the opacity, high viscosity, and light refraction—caused by the composite nature of the resin, an optimization of the printing parameters such as layer thickness, exposure time, heating of the resin, laser intensity, and brightness of UV light was achieved. Printed items were subjected to an additional thermal post-processing step with a view to reach the best compromise between electrochemical performances and mechanical integrity. The results obtained through this research will pave the way toward the development of 3D-printed batteries via VPP. |
