| Abstract: | Selective laser-induced etching enables the high-precision fabrication of three-dimensional components from transparent materials. First, ultrashort pulsed, tightly focused laser radiation is used to create a modification within the bulk of the transparent material. By selectively moving the focus, entire contiguous surfaces and volumes can be modified. Subsequently, the modified areas are etched free using an etching liquid. Thus, the desired three-dimensional component is exposed and separated from the surrounding material. Using the SLE process, molding tools made of fused silica are fabricated with functional structures of less than 150 µm in size. By molding the solid-state electrolyte foil of a sodium-based battery cell, the contact areas between the chemical components are increased to enhance the power density. Different structural geometries and dimensions are compared to increase this effect. [ABSTRACT FROM AUTHOR] |
