Abstract
A lithium electrochemical storage battery including: at least one electrochemical cell; two current collectors, one of which is connected to the anode and the other to the cathode; and a casing of longitudinal axis X, the casing including a cap, a bottom, a lateral jacket joined both to the bottom and to the cap, and a central core arranged along the axis X, the central core being hollow at least over some of its height and made of a material the melting point of which is higher than the temperature reached by the cell when it malfunctions, the hollow portion of the central core opening onto the exterior of casing via the bottom and/or the cap and the central core having, at least one end of its hollow portion, an internal thread into which an external thread of a part forming one pole of the storage battery may be screwed.
