Abstract
The invention concerns a battery including a metallic container (1) delimiting a cavity (16) containing an electrolyte and a composite strip (2) formed by a first metallic sheet coated with a material forming the positive electrode, by a second metallic strip coated with a material forming the negative electrode and by porous insulating separators, composite strip (2) being wound onto a core (20) located at the centre of the cavity (16) and electrodes being connected by connecting means (8, 9) to external terminals (6, 7). It is characterized in that all or part of the central core (20) is made of a material with a high heat transmission coefficient in heat contact with at least the metallic closing cap (3).
