On November 14, several partners from our project participated in the Battery Innovation Day held in Bordeaux at the Center de congrès Cité Mondiale. Circular Wallonia Days is an inclusive event dedicated to promoting circularity of the battery value chain. Today’s leading European research and innovation initiatives (Batteries Europe, Battery 2030+ and the European Battery Association) in partnership with the 1st and 2nd Battery IPCEI, have organized a unique hybrid experience, designed to bring together numerous key players and experts in the battery field.
