Future in Battery Production: An Extensive Benchmarking of Novel Production Technologies as Guidance for Decision Making in Engineering

Due to the rising interest in electric vehicles, demand for more efficient battery cells is increasing rapidly. To support this trend, must become much cheaper and “greener.” Energy consumption during production a major driver of cost CO $_2$ emissions. The drying step one energy consumers drivers. technological approach “dry coating” allows energy-intensive be eliminated significant savings. However, there are numerous emerging dry coating technologies that differ significantly physics, chemistry, readiness levels. Moreover, typical methodological procedures technology selection remain less applicable early stages development. Both issues raise questions, “What most promising technology?” “How do we identify it?” answer these comprehensive, systematic benchmark was conducted. Following four-step analytical approach, based on nominal group technique, qualitative content analysis, multicriteria decision different were identified, analyzed, cross-compared. This performed qualitatively quantitatively. We also forecast which factor will impact application emission rate reductions savings 2030. In summary, four identified with high chance breakthrough within next 3–5 years. By applying technologies, 4.76 million tons could saved per year by
