<p>1. An electrochemical battery of the primary type or of the secondary type, comprising a plurality of cells each constituted by a negative electrode whose active material is selected from lithium, magnesium, and alloys thereof, an electrolyte based on a solid polymer selected from polyoxyethylene, polypropylene, and derivatives thereof, and forming a complex with an alkali salt, and a positive electrode whose active material is selected from oxides such as MnO2 , CrO2 , sulfides such as FeS2 , TiS2 , MoS3 , sulfur, and polysulfides and derivatives thereof, and provided with heating means for heating the electrolyte, the battery being characterized by the fact that said heating means, comprising a pyrotechnical composition associated with a fuse, is suitable for raising said electrolyte to a temperature lying between 150 degrees C and 170 degrees C when said negative electrode is made of lithium, and lying between 150 degrees C and 250 degrees C when said negative electrode is made of magnesium, said heating means being associated with a thermal buffer selected from an aliphatic oil, a silicone oil, a fusible salt, and a polymer which melts at the desired battery operating temperature.</p> |
