Batteries sodium-ion pour systèmes de stockage d’énergie résidentiels
Aperçu du projet
Partout dans le monde, les batteries lithium-ion jouent un rôle crucial dans le stockage de l’énergie, des systèmes de services publics à grande échelle (p. ex. : Megapack de Tesla) aux solutions résidentielles (Powerwall de Tesla). Toutefois, comme il est prévu que l’électrification à l’échelle mondiale se poursuive au-delà de 2030, les inquiétudes concernant la disponibilité du lithium se font de plus en plus vives. Les chercheurs se tournent donc vers une autre solution viable, les batteries sodium-ion.
Ce projet étudie le potentiel des batteries sodium-ion pour le stockage d’énergie résidentiel. En collaboration avec Faradion, un partenaire industriel de premier plan, la recherche vise la mise au point de petites cellules poches et d’électrolytes répondant aux exigences particulières des systèmes sodium-ion.
