ELECTROLYTE FOR OXYGEN (AIR)-METAL CHEMICAL POWER SOURCE Russian patent published in 1998 - IPC

FIELD: chemical power sources. SUBSTANCE: electrolyte contains alkali metal chloride and hydroxide solution with corrosion inhibiting additive. According to invention, this additive is alkali metal stannate and, as alkali metal, sodium is used, contents of components being the following (in wt %): sodium chloride, 5-30; sodium hydroxide, 0.5-25; sodium stannate, at least 0.2; and water, the balance. To enhance gelation suppression effect, electrolyte may be supplemented by less than 0.01 wt % of sodium carbonate, bicarbonate, and sulfate or by 0.001 to 1.0 wt % of organic flocculant based on polyacrylic compounds. EFFECT: improved performance and energetic characteristics of chemical power sources and increased coefficient of anode material utilization. 3 cl
