Ampere, l\u2019entit\u00e9 d\u00e9di\u00e9e aux v\u00e9hicules \u00e9lectriques et aux logiciels de Renault Group, a sign\u00e9 un accord de d\u00e9veloppement\u00a0 avec l’am\u00e9ricain\u00a0 Stratus Materials\u00a0 d\u00e9veloppeur de premier plan de mat\u00e9riaux actifs de cathode (CAM) \u00e0 haute \u00e9nergie sans cobalt LXMOTM<\/sup>\u00a0pour batteries lithium-ion avanc\u00e9es. <\/strong><\/p>\n

Cet accord marque une premi\u00e8re \u00e9tape dans l\u2019\u00e9valuation de la pertinence de l\u2019int\u00e9gration de la technologie LXMOTM<\/sup> sans cobalt de Stratus Materials dans la flotte de v\u00e9hicules \u00e9lectriques de Renault Group. Il vise \u00e0 d\u00e9montrer les hautes performances de ce mat\u00e9riau dans des cellules de batterie au format v\u00e9hicule \u00e9lectrique. Cette nouvelle technologie sera test\u00e9e dans le Laboratoire Innovation Cellule Batterie d\u2019Ampere \u00e0 Lardy.<\/p>\n

Une technologie prometteuse<\/strong><\/p>\n

La technologie des batteries bas\u00e9es sur la technologie LXMOTM\u00a0 \u00a0 <\/sup>est particuli\u00e8rement prometteuse, pour offrir une densit\u00e9 \u00e9nerg\u00e9tique \u00e9lev\u00e9e, comparable voire sup\u00e9rieure \u00e0 celle des batteries NMC (Nickel, Mangan\u00e8se, Cobalt) en offrant une r\u00e9duction de co\u00fbt et une similarit\u00e9 avec les batteries LFP (Lithium, Fer, Phosphate). \u00c0 l\u2019\u00e9chelle du syst\u00e8me, la combinaison d\u2019une meilleure tol\u00e9rance aux d\u00e9fauts permet d\u2019atteindre des densit\u00e9s \u00e9nerg\u00e9tiques au niveau du pack jusqu\u2019\u00e0 deux fois sup\u00e9rieures \u00e0 celles des packs de batteries bas\u00e9s sur des chimies NMC ou LFP. Il est \u00e9vident que Cela se traduit par des avantages significatifs en mati\u00e8re de conception et d\u2019\u00e9conomie pour Ampere. La promesse est all\u00e9chante avec des v\u00e9hicules moins co\u00fbteux, ayant une plus grande autonomie et une meilleure s\u00e9curit\u00e9.<\/p>\n

La technologie sans cobalt repr\u00e9sente la troisi\u00e8me \u00e9tape de la strat\u00e9gie batterie d\u2019Ampere, apr\u00e8s les batteries NMC pour leur haute densit\u00e9 \u00e9nerg\u00e9tique, et les batteries LFP qui seront int\u00e9gr\u00e9es aux v\u00e9hicules Renault \u00e0 partir de 2026.<\/p>\n

Nicolas Racquet, Directeur Ing\u00e9nierie V\u00e9hicule et Powertrain, Ampere a d\u00e9clar\u00e9 :\u201cAmpere s\u2019int\u00e9resse de pr\u00e8s aux mat\u00e9riaux \u00e0 haute densit\u00e9 \u00e9nerg\u00e9tique sans cobalt, en raison de leurs avantages potentiels par rapport aux mat\u00e9riaux de cathode traditionnels. Les mat\u00e9riaux actifs de cathode LXMOTM\u00a0<\/sup>de Stratus ont retenu l\u2019attention d\u2019Ampere gr\u00e2ce \u00e0 leur combinaison unique et convaincante de performance, de co\u00fbt, de s\u00e9curit\u00e9 et de dur\u00e9e de vie.\u201d<\/p>\n

De son c\u00f4t\u00e9, Jay Whitacre, CEO de Stratus a comment\u00e9:\u201c <\/em>Nous sommes ravis que la technologie LXMOTM<\/sup> ait \u00e9t\u00e9 s\u00e9lectionn\u00e9e par Ampere et Renault Group comme candidate pour une int\u00e9gration dans leur future gamme de v\u00e9hicules. Les progr\u00e8s r\u00e9alis\u00e9s jusqu\u2019\u00e0 pr\u00e9sent avec Ampere sont prometteurs. Avec cet accord, le d\u00e9veloppement commun (JDA) en cours va nous permettre d\u2019avancer ensemble vers une mise en \u0153uvre \u00e0 grande \u00e9chelle dans les v\u00e9hicules.\u201d<\/em><\/p>\n

Dans un contexte o\u00f9 les mat\u00e9riaux de batterie avanc\u00e9s, les cellules et les packs jouent un r\u00f4le essentiel dans les v\u00e9hicules \u00e9lectriques, cette annonce illustre la volont\u00e9 d\u2019Ampere de s\u2019imposer comme un acteur de r\u00e9f\u00e9rence dans les technologies EV.\u00a0<\/p>\n","protected":false},"excerpt":{"rendered":"
