Abstract Scope |
Solid-state electrolytes are being developed for the solid-state batteries using Direct-Ink Write process. In this work, colloidal pastes of ceramic type Li-garnet solid-state electrolyte (Li6.75La3Zr1.75Ta0.25O12) in 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 1100oC and 1250oC for durations ranging from 2 to 6 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 electrolytes for solid-state batteries. |
