METHOD FOR RAISING PERFORMANCE CHARACTERISTICS OF LEAD STORAGE BATTERIES Russian patent published in 1999 - IPC

FIELD: chemical power supplies. SUBSTANCE: storage battery uses fluorine-containing surface-active materials based on perfluorosulfuric or perfluorocarbonic acids or their mixtures. Introduction of such material in electrolyte or, for example, pre-assembly treatment of storage battery plates with solution of fluorine-containing surface-active material provides for liberation of increased amount of hydrogen on lead and its alloys in sulfuric acid solutions. Using fluorine-containing surface-active material reduces rate of hydrogen liberation both in the course of battery charging and its storage. Reducing rate of lead-electrolyte reaction reduces non-treated sulfation of plates during battery service. EFFECT: improved performance characteristics of storage battery. 3 cl, 2 ex
