The search for materials to drive e-mobility forward is at the core of the decarbonisation EU program. The most promising candidates include high-capacity and high-voltage cathode oxides and metallic anodes. These materials will be presented and discussed in terms of performance and sustainability, together with the optimisations conducted in the frame of the EU projects 1) COBRA [H202:875568], 2) IntelLiGent [HORIZON; 101069765] and 3) SPINMATE [HORIZON: 101069712]. The presentation will also include aspects related to material scale-up and (generation 3b) battery cell fabrication.
