Title (EN) ELECTROCHEMICAL CELL HAVING A FIXED CELL ELEMENT
(FR) CELLULE ÉLECTROCHIMIQUE AYANT UN ÉLÉMENT DE CELLULE FIXE
Abstract:
(EN) An electrochemical cell includes a cell element and a current collector disposed in a housing that includes a vent. The current collector includes an outer member and an inner member coupled together by one or more flexible arms. The outer member is coupled to the cell element and the inner member is coupled to the vent, such that the flexible arms allow axial movement of the inner member with respect to the outer member when the vent moves from an undeployed position to a deployed position. The housing may include a shoulder that holds the cell element in the housing. The electrochemical cell may also include a coil plate provided at an end of the cell element. The coil plate is coupled to an edge of at least one electrode of the cell element. The outer member of the current collector may be coupled to the coil plate and the inner member of the current collector may be coupled to the vent, such that when the vent moves from an undeployed position to a deployed position, the cell element remains substantially fixed within the housing.
(FR) Une cellule électrochimique comporte un élément de cellule et un collecteur de courant disposés dans un boîtier qui comporte un orifice. Le collecteur de courant comporte un membre externe et un membre interne couplés ensemble par un ou plusieurs bras flexibles. Le membre externe est couplé à l'élément de cellule et le membre interne est couplé à l'orifice de sorte que les bras flexibles permettent un mouvement axial du membre interne par rapport au membre externe lorsque l'orifice se déplace d'une position non déployée à une position déployée. Le boîtier peut comporter un épaulement qui maintient l'élément de cellule dans le boîtier. La cellule électrochimique peut également comporter une plaque de bobine disposée à l'extrémité de l'élément de cellule. La plaque de bobine est couplée à un bord d'au moins une électrode de l'élément de cellule. Le membre externe du collecteur de courant peut être couplé à la plaque de bobine et le membre interne du collecteur de courant peut être couplé à l'orifice de sorte que, lorsque l'orifice se déplace d'une position non déployée à une position déployée, l'élément de cellule reste pratiquement fixe dans le boîtier.
