SOLID-STATE CHEMICAL CURRENT SUPPLY Russian patent published in 1999 - IPC

FIELD: self- contained primary batteries for continuous power supply systems. SUBSTANCE: current supply has anode made of rare-earth metals or their alloy, fluorine ion-conducting electrolyte composed of at least one rare-earth metal fluoride and one alkaline-earth metal fluoride, and cathode made of mixture of metal oxide and ion-conducting complex fluoride that has in its composition, apart from fluorine, at least two metals of different valence. Cathode has in its composition 11.5-96.9 mole percent of complex fluoride and 3.1-88.5 mole percent of metal oxide. Metal oxide may be cupric oxide CuO, lead oxide PbO₂, manganese oxide MnO₂, vanadium oxide V₂O₅, or silver oxide Ag₂O. Open- circuit voltage of current supply is up to 3.9 V, operating temperature range is between room temperature and 500 C. EFFECT: improved performance characteristics. 6 cl, 2 dwg, 2 tbl, 15 ex
