Li-ion battery (LIB) are being recognized as one of the key technologies of our time. They can potentially unlock the widespread success of electric vehicles (EVs), while assuring more flexible electric grids. Nevertheless, high enough electrochemical performance and cycle life, as well as low cost, CO2 footprint and a stable raw materials supply chain, are essential requisite to make sustainable the production upscale of LIBs. In this context, international actions underlining the importance of sustainable LIBs production, as the European 8 and global 9 battery alliance and the battery passport, 10 are particularly important. One way of improving LIBs performance and decreasing their cost is through novel materials. However, after three decades of commercial success of LIBs, the cathode's and anode's chemistries are rather similar to the ones commercialized in 1991 by Sony (LiCoO2 | graphite), namely layered transition metal oxides (as LiNixMnyCozO2) cathodes and carbon-based anodes, respectively. Then, an alternative pathway to enhance LIBs performance, cost and CO2 footprint relies on optimizing composite electrodes, cells and battery packs manufacturing. It has been estimated that the composite electrodes production alone account for ~40% of the battery cells production cost, and, in between them, >50% comes from slurry coating and solvent evaporation. In another study, Schünemann et al. found that coating and drying represent the main cost of electrode and cell manufacturing, except for the cost of materials.
