SOLiTHOR, en Belgique, a r\u00e9alis\u00e9 plus de 1000 cycles pour une batterie lithium-m\u00e9tal solid state de 3Ah destin\u00e9e \u00e0 des applications a\u00e9ronautiques et maritimes.<\/p>\n

Des essais r\u00e9cents sur les piles \u00e0 poche de SOLiTHOR<\/a>, effectu\u00e9s \u00e0 une temp\u00e9rature mod\u00e9r\u00e9e (25\u00b0C) et avec une pression externe inf\u00e9rieure \u00e0 72 psi\/4,9 atm, ont montr\u00e9 1000 cycles de d\u00e9charge \u00e0 pleine charge jusqu’\u00e0 une capacit\u00e9 de 80 % avec une efficacit\u00e9 coulombienne sup\u00e9rieure \u00e0 99,2 %.<\/p>\n

Il s’agit d’une d\u00e9monstration r\u00e9ussie de l’utilisation de son \u00e9lectrolyte solide mince de premi\u00e8re g\u00e9n\u00e9ration, associ\u00e9 \u00e0 des cathodes minces en lithium m\u00e9tal et \u00e0 des cathodes NMC \u00e0 forte charge. Cette combinaison pr\u00e9sente des densit\u00e9s \u00e9nerg\u00e9tiques de 384 Wh\/kg et de 1 026 Wh\/l au niveau de l’empilement, obtenues sur un ensemble diff\u00e9rent de cellules. Ces r\u00e9sultats d\u00e9passent l’objectif initial de 850 Wh\/l.<\/a><\/p>\n

En tant que tremplin vers des d\u00e9monstrateurs technologiques \u00e0 l’\u00e9chelle r\u00e9elle, SOLiTHOR a fabriqu\u00e9 avec succ\u00e8s des prototypes de poches de cellules de 3 Ah qui sont actuellement soumis \u00e0 ses protocoles internes d’essais de performance et de s\u00e9curit\u00e9. Son plan \u00e0 court terme est d’envoyer ces prototypes pour une validation et des essais externes avec des partenaires a\u00e9ronautiques et maritimes.<\/p>\n

L’essai visait \u00e0 mesurer l’endurance, un crit\u00e8re de performance essentiel pour les applications a\u00e9ronautiques et maritimes \u00e0 longue dur\u00e9e de vie. Le r\u00e9sultat a \u00e9t\u00e9 bien sup\u00e9rieur \u00e0 l’objectif commercial attendu, avec des valeurs d’\u00e9nergie gravim\u00e9trique cruciales pour permettre la transition \u00e9lectrique des secteurs a\u00e9ronautique et maritime, qui n\u00e9cessitent des batteries plus l\u00e9g\u00e8res, plus s\u00fbres et plus puissantes, en particulier pour le d\u00e9collage et l’atterrissage.<\/p>\n

La technologie des accumulateurs \u00e0 semi-conducteurs est enti\u00e8rement compatible avec les composants cathodiques commerciaux fabriqu\u00e9s aujourd’hui dans l’industrie bien \u00e9tablie des accumulateurs Li-ion. Cela permettra l’industrialisation rapide de ces produits dans les ann\u00e9es \u00e0 venir sur les lignes de production de batteries Li-ion existantes.<\/p>\n

\u00ab\u00a0Ce r\u00e9sultat exceptionnel en mati\u00e8re de cyclabilit\u00e9 souligne la durabilit\u00e9 et la compatibilit\u00e9 de notre \u00e9lectrolyte solide mince innovant avec les composants de cathode minces au lithium m\u00e9tal et conventionnels. Les recherches men\u00e9es depuis plusieurs d\u00e9cennies visent \u00e0 atteindre une telle cyclabilit\u00e9 pour les technologies de batteries minces au lithium m\u00e9tal et nous sommes parmi les rares entreprises \u00e0 l’avoir d\u00e9montr\u00e9e dans une configuration \u00e0 l’\u00e9tat solide\u00a0\u00bb, a d\u00e9clar\u00e9 le Dr Fanny Bard\u00e9, directeur de la technologie de SOLiTHOR.<\/p>\n

\u00ab\u00a0SOLiTHOR est en partenariat avec des constructeurs a\u00e9ronautiques et maritimes. Les v\u00e9hicules a\u00e9riens et maritimes ont besoin d’une puissance et d’une \u00e9nergie \u00e9lev\u00e9es pour fournir l’\u00e9lectrification n\u00e9cessaire au transport en toute s\u00e9curit\u00e9 des a\u00e9ronefs et des navires sur de longues distances. Les r\u00e9alisations ci-dessus d\u00e9montrent notre capacit\u00e9. L’un des objectifs \u00e0 long terme de SOLiTHOR est de s’associer \u00e0 des fabricants de batteries pour produire en masse les cellules, \u00e0 la fois pour nos clients de l’aviation et de la marine\u00a0\u00bb, a d\u00e9clar\u00e9 Huw Hampson-Jones, PDG de SOLiTHOR.<\/p>\n
