Additive manufacturing offers several benefits including the capabilities for flexible battery architectures. Solid-state batteries are being developed to overcome the drawbacks of lithium-ion batteries such as low energy density and fire safety concerns. In this work, colloidal pastes of ceramic type Li-garnet solid-state electrolyte (Li6.75La3Zr1.75Ta0.25O12) blended with photocurable resin were used to 3D print test samples. The pastes demonstrated promising printing behaviors that allow the fabrication of various structures. The samples were sintered at temperatures between 900oC and 1250oC for durations ranging from 1 to 12 hours. X-ray diffraction shows that they maintain single cubic Li-garnet phase. They were densifiable to high relative densities based on SEM observations. The ionic conductivities of the samples were obtained. The results shows that 3D printing is a promising route for fabricating solid-state batteries.
