| Abstract Scope |
As classical lithium-ion batteries are based on a planar architecture consisting of the 2D stacking of components (current collectors, electrodes, separator/electrolyte), 3D printing technologies have the potential to revolutionize the production of shape-conformable batteries, with increased specific surface area, ion diffusion, and improved power performances. This study presents the preparation of several UV photocurable resins with different liquid electrolyte-to-polymer matrix ratios, designed to act as gel polymer electrolytes (GPE) once printed by the vat photopolymerization (VPP) 3D printing process. Printing parameters are optimized to ensure print quality and accuracy. The 3D-printed GPE is examined through electrochemical impedance spectroscopy to maximize the ionic conductivity while ensuring satisfactory printability. Finally, electrochemical testing of the 3D-printed GPEs is performed to demonstrate their functionality in a classical lithium-ion battery. This work seeks to achieve the 3D printing via VPP of a complete lithium-ion battery, a world first. |
