SCALABLE AND SUSTAINABLE PILOT LINE BASED ON INNOVATIVE MANUFACTURING TECHNOLOGIES TOWARDS THE INDUSTRIALISATION OF SOLID-STATE BATTERIES FOR THE AUTOMOTIVE SECTOR
SPINMATE aims to demonstrate a scalable, sustainable, safe and cost-effective digital-driven proof-of-concept pilot line, at a TRL6 level, as a first step towards the large-scale manufacturing of generation 4b (Gen 4b) SSB cells and module, in order to support the electrification of the automotive sector. To do so, SPINMATE proposes the development and implementation of innovative and scalable manufacturing and processing solutions (notching/cutting, stacking and sealing/packaging steps, among others). Furthermore, new industry 4.0 and 5.0 concepts (Industrial Internet of Things – IIoT and Machine Learning – ML algorithms, Digital Twins, giga-factory line simulation,…) are proposed to be applied for the digitalisation of the proof-of-concept pilot line, as well as the assembly and manufacturing processes. Thus, SPINMATE will manufacture small 1 Ah and large 10 Ah SSB cells, after the development and optimisation of (i) advanced solid polymer electrolyte with high ionic conductivity and wide electrochemical stability, (ii) Li metal foil with surface treatment enabling a more stable interface as anode and (iii) Ni-rich layered oxide cathode with improved cycling stability. Regarding electrodes (i.e. anode and cathode) and electrolyte processing, innovative solvent-free extrusion routes, roll-to-roll approach and optimised solvent casting methods are suggested. SPINMATE’s Gen 4b SSB cells will create a new industry value chain in Europe towards their commercialisation. This new generation technology will ensure (i) enhanced energy densities, overcoming current LIB limitations, (ii) improved safety in both solutions and workers; (iii) increased sustainable mass production; and (iv) decreased carbon footprint and cost.
