ABSTRACT:
The invention concerns an electric cell having a fluid-tight box comprising a metallic tank having a bottom and a lateral wall and at least one current output insulated from the tank. That cell is characterized more particularly in that the housing comprises, moreover, a metallic sleeve surrounding the lateral wall of the tank, stopped up in a fluid-tight manner at its first end by the tank and at its second end by a glass seal through which the current output crosses in a fluid-tight manner. The glass seal and metallic sleeve have substantially equal coefficients of expansion. The invention applies to electrochemical cells having small dimensions and more particularly to lithium cells.
