Title (EN) DIMENSIONAL CONSTRAINTS FOR THREE-DIMENSIONAL BATTERIES
(FR) LIMITATIONS DIMENSIONNELLES DESTINÉES À DES BATTERIES TRIDIMENSIONNELLES
Abstract:
(EN) A secondary battery is provided for cycling between a charged and a discharged state, the secondary battery including a battery enclosure, an electrode assembly, carrier ions, a non-aqueous liquid electrolyte within the battery enclosure, and a set of electrode constraints. The set of electrode constraints includes a primary constraint system having first and second primary growth constraints and at least one primary connecting member, the first and second primary growth constraints separated from each other in the longitudinal direction, wherein the primary constraint array restrains growth of the electrode assembly in the longitudinal direction such that any increase in the Feret diameter of the electrode assembly in the longitudinal direction over 20 consecutive cycles of the secondary battery is less than 20%. The set of electrode constraints further includes a secondary constraint system having first and second secondary growth constraints connected by at least one secondary connecting member, wherein the secondary constraint system at least partially restrains growth of the electrode assembly in a second direction upon cycling of the secondary battery.
(FR) L'invention concerne une batterie secondaire destinée à fonctionner en cycles entre un état chargé et un état déchargé, la batterie secondaire comprenant un boîtier de batterie, un ensemble à électrodes, des ions porteurs, un électrolyte liquide non aqueux à l'intérieur du boîtier de batterie, et un ensemble d'éléments de limitation d'électrodes. L'ensemble d'éléments de limitation d'électrodes comprend un système d'éléments de limitation primaires comportant des premier et second éléments de limitation de dilatation primaires et au moins un élément de liaison primaire, les premier et second éléments de limitation de dilatation primaires étant séparés l'un de l'autre dans la direction longitudinale, le système d'éléments de limitation primaires limitant la dilatation de l'ensemble à électrodes dans la direction longitudinale de manière que toute augmentation du diamètre de Féret de l'ensemble à électrodes dans la direction longitudinale pendant 20 cycles consécutifs de la batterie secondaire soit inférieure à 20 %. L'ensemble d'éléments de limitation d'électrodes comprend en outre un système d'éléments de limitation secondaires comportant des premier et second éléments de limitation de dilatation secondaires reliés par au moins un élément de liaison secondaire, le système d'éléments de limitation secondaires limitant au moins partiellement la dilatation de l'ensemble à électrodes dans une seconde direction lors du fonctionnement en cycles de la batterie secondaire.
