Abstract Scope |
Additive manufacturing enables the development of shape-conformable lithium-ion batteries with enhanced power performances. In this work, a custom LiClO4-based UV-photocurable resin is developed to serve, once printed, as a solid polymer electrolyte (SPE) component within lithium-ion batteries. SPE presents improved safety in comparison with traditional liquid electrolytes that use flammable solvents. The Digital Light Processing (DLP) vat photopolymerization process is employed to print complex geometries of the solid electrolyte component, demonstrating its design flexibility for its implementation into future battery architectures. The electrochemical and mechanical properties of various poly (ethylene glycol) diacrylate (PEGDA) polymer matrices with different molecular weights are analyzed and optimized. Linear sweep voltammetry, potentiostatic electrochemical impedance spectroscopy, galvanostatic cycling tests, as well as tensile strength tests are performed on the printed items. The need for a compromise between electrochemical and mechanical performances is also presented. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. |
