Abstract

Une batterie (1) comprenant :- au moins deux éléments électrochimiques (2-1, 2-2) de format parallélépipèdique, - une première couche (3-1) d’un matériau réfractaire résistant à une température allant jusqu’à 1200°C disposée au contact de la totalité d’une première face qui est l’une des faces (4) de plus grande aire de l’un (2-1) des éléments électrochimiques, ladite première couche comportant une région centrale (C) ayant pour centre le centre de la première couche et ayant une aire représentant de 30 à 60% de l’aire de ladite première face ;- une cale rigide (5) présentant une dureté supérieure ou égale à 90 Shore A selon la norme ASTM D 2240-15(2021), disposée entre ladite première couche et le second élément électrochimique (2-2), la cale rigide étant située hors de la région centrale de ladite première couche.
