Title
(EN) THERMALLY CONDUCTIVE DIVIDER CONFIGURATION FOR BATTERIES
(FR) CONFIGURATION DE SÉPARATEUR THERMOCONDUCTEUR DE BATTERIES
Abstract
(EN) The present disclosure includes systems, devices, and methods of using a battery pack. The battery pack includes a plurality of cells and a divider. The plurality of cells includes a first cell and a second cell and a divider positioned between the first cell and the second cell and configured such that an in-plane conductivity of the divider is 0.1-100 watts per meter Kelvin, an in-plane conductivity of a cell is 1-100 watts per meter Kelvin, or a combination thereof. In some aspects, the divider may include a first surface configured to face the first cell and interposed between the first cell and the second cell and a second surface that extends from the first surface and faces the first cell and is interposed between the first cell and the third cell.
(FR) La présente invention divulgue des systèmes, des dispositifs et des procédés d'utilisation d'un bloc-batterie. Le bloc-batterie comprend une pluralité de cellules et un séparateur. Les cellules de la pluralité de cellules comprennent une première cellule et une seconde cellule et un séparateur positionné entre la première cellule et la seconde cellule et conçu de sorte qu'une conductivité dans le plan du séparateur soit de 0,1 à 100 watts par mètre Kelvin, qu'une conductivité dans le plan d'une cellule soit de 1 à 100 watts par mètre Kelvin, ou une combinaison de ces dernières. Selon certains aspects, le séparateur peut comprendre une première surface conçue pour faire face à la première cellule et pour se trouver interposée entre la première cellule et la deuxième cellule et une seconde surface qui s'étend depuis la première surface et qui fait face à la première cellule et qui est interposée entre la première cellule et la troisième cellule.
