Europe’s objective to have 30 million electric vehicles (EVs) by 2030 can only be achieved by large scale, in-house production of highly effective and performant batteries. Development of solid-state battery technologies could improve the energy density and safety of lithium metal solid state batteries. PULSELiON project aims to develop the manufacturing process of Gen 4b solid-state batteries (SSBs) based on lithium-metal anode, sulfide solid electrolytes, and Nickel-rich NMC cathode. Novel pulsed laser deposition technique developed by PULSEDEON will be adapted and modified into a single-step vacuum process for safe and efficient manufacturing of anode components composed of lithium metal, protective layers, and sulfide based solid electrolytes. The cathode layer will be made based on conventional wet processing techniques. Initially, the anode and cathode layers will be developed in small scale for making coin cells and monolayer cells for optimising the materials and process. SSB cells will be developed with optimised process routes and will be upscaled to a pilot line proof-of-concept (TRL 6) by manufacturing large scale solid-state batteries (10 Ah). Digitalisation will be incorporated in the process modelling task with the inputs obtained from process upscaling and cell testing tasks, which will enable efficient process optimisation.
