Abstract
(EN) A solid state battery (22) including a stack of cells (26) defining a stacking direction (20), each cell comprising a positive electrode (12), a negative electrode (14) and a solid electrolyte (16) disposed between the positive electrode (12) and the negative electrode (14), wherein the stack of cells (26) is enclosed in a container (24), wherein the stacking direction (20) forms an angle (Θ) that is different from 0° with a vertical direction (V), the vertical direction (V) being parallel to a direction of a gravitational force, wherein the positive electrode (12) comprises sulfur as an active material, and wherein the container (24) comprises a void volume (28) equal to or greater than a volume of sulfur contained in the stack of cells (26), the void volume (28) being disposed below the stack of cells (26) in the vertical direction (V).
(FR) L'invention concerne une batterie solide à semiconducteur (22) comprenant un empilement de cellules (26) définissant une direction d'empilement (20), chaque cellule comprenant une électrode positive (12), une électrode négative (14) et un électrolyte solide (16) disposé entre l'électrode positive (12) et l'électrode négative (14), l'empilement de cellules (26) étant enfermé dans un récipient (24), la direction d'empilement (20) formant un angle (Θ) qui est différent de 0° avec une direction verticale (V), la direction verticale (V) étant parallèle à une direction d'une force gravitationnelle, l'électrode positive (12) comprenant du soufre en tant que matériau actif, et le récipient (24) comprenant un volume de vide (28) supérieur ou égal à un volume de soufre contenu dans l'empilement de cellules (26), le volume de vide (28) étant disposé au-dessous de l'empilement de cellules (26) dans la direction verticale (V).
