Title (EN) ELASTIC BELLOWS AND BATTERY CELL ASSEMBLIES INCLUDING SAME
(FR) SOUFFLET ÉLASTIQUE ET ENSEMBLES DE CELLULES DE BATTERIE LE COMPRENANT
Abstract:
(EN) A battery pack includes a battery housing and electrochemical cells disposed in the battery housing in a stacked configuration. Elastic members are disposed between adjacent cells of a cell stack. Each elastic member is a bladder that is formed of a pair of contoured plate portions stacked in a mirrored arrangement, whereby the plate portions cooperate to form a bellows-type compression spring. The elastic members provide a predetermined compression force to each cell while accommodating cell growth during use. The elastic members may include surface features such as strategically shaped and/or located protrusions that are configured to permit compliance and can be tuned to address the requirements of a specific application and permit application of varying stiffness characteristics across a surface of a cell.
(FR) Un bloc-batterie comprend un boîtier de batterie et des cellules électrochimiques disposées dans le boîtier de batterie dans une configuration empilée. Des éléments élastiques sont disposés entre les cellules adjacentes d'un empilement de cellules. Chaque élément élastique est une vessie qui est constituée d'une paire de parties de plaque profilée empilées dans un agencement en miroir, de sorte que les parties de plaque coopèrent pour former un ressort de compression de type soufflet. Les éléments élastiques donnent une force de compression prédéterminée à chaque cellule tout en s'adaptant à la croissance de cellule pendant l'utilisation. Les éléments élastiques peuvent comprendre des caractéristiques de surface telles que des saillies mises en forme et/ou disposées de manière stratégique qui sont conçues pour permettre une conformité et peuvent être accordées pour répondre aux besoins d'une application spécifique et permettre l'application de caractéristiques de rigidité variable sur la surface d'une cellule.
