Solid electrolyte components of lithium lanthanum zirconate(LLZ)were successfully fabricated using stereolithographic based Additive Manufacturing(STL-AM)for all solid batteries. Micro-embossed patterns were introduced into ultrathin electrolyte sheets to increase energy density and decrease internal resistance through computer-aided design, manufacture, and evaluation (CAD/CAM/CAE). The two-dimensional (2D)patterns were precisely formed by UV-laser scanning on photosensitive LLZO nanoparticle-acrylic resin composite surfaces. Three-dimensional(3D)structures were fabricated automatically by continuous laminations of the drawn layers and interlayer chemical bonding. These STL components were processed using cold isostatic pressing(CIP)to closely infuse the acrylic matrix with LLZ nanoparticles. Microstructural densification can be realized after dewaxing and sintering in the air atmosphere.
