3DPrintBatt

Project discription

The goal of 3DPrintBatt is to build an intelligent and agile TRL 7 prototype production system for the manufacturing of solid-state sodium-ion battery cells based on additive printing technology. The project will develop the print-based manufacturing of sodium-ion solid-state batteries (Na-SSBs), which has not been realized in an industrial setting to date, and thus establish a next-generation battery cell manufacturing process that conserves resources. These Na-SSBs do not require materials that are critical in many ways, such as lithium (Li) and cobalt (Co). Furthermore, the absence of a liquid electrolyte and the use of solid, metallic electrodes allows an overall highly stable battery concept that impresses with high energy densities and increased safety in operation and production. Na-SSBs are highly innovative and thus a competing system to the currently dominant lithium-ion batteries (LIBs) that is worth exploring and, with appropriate process and material optimization, ecologically and economically superior. Against this background, 3DPrintBatt wants to advance the further development of this battery cell type and realize an immediate implementation in industrial production.

The project goals of the iPAT include

• Development of a continuous and scalable paste production for the printing of the anode, the cathode and the separator under consideration of economic aspects
• Adaptation and optimization of the anode, cathode and separator pastes of a sodium-based solid-state battery to the printing process
• Creation and evaluation of a catalog of requirements for the recycling of sodium-ion batteries
• Investigation and evaluation of safety advantages of sodium-based solid-state batteries compared to conventional LIBs
• Investigation of the recyclability of sodium-ion batteries
