Thermal battery
Abstract
Abstract A THERMAL BATTERY HAVING A PLURALITY OF STACKED ELECTRO-CHEMICAL COUPLES EACH INCLUDING A PAIR OF POSITIVE AND NEGATIVE ELECTRODES BETWEEN WHICH IS SANDWICHED A SOLID ELECTROLYTE LIQUIFIABLE WHEN SUFFICIENTLY HEATED TO PROVIDE SUBSTYANTIALLY INSTANTANEOUS BATTERY ACTIVATION. AND A PLURALITY OF INSULATING RINGS EACH ASSOCIATED WITH A DIFFERENT PAIR OF ELECTRODES AND ENCLOSING THE PERIPHERAL EDGE OF ONLY ONE OF THE ELECTRODES OF THE ASSOICATED PAIR FOR PREVENTING ALLOYS WHICH FORM BY CHEMICAL INTERACTING OF THE ELECTROLYTE AND ONE OR MORE OF THE ELECTRODES FROM BRIDING AND THEREBY SHORT-CIRCUITING THE ELECTRODE PAIR, IN A PREFERRED THERMAL BATTERY, THE INSAULATING RING OF EACH COUPLE ALSO ENCLOSES THE PERIPHERAL EDGE OF THE ELECTROLYTE, PREVENTING THE ELECTROLYTE, WHEN LIQUIFIED FROM LEAVING THE SPACE BETWEEN THE ELECTRODES AND THEREBY INCREASING THE BATTERY INTERNAL RESISTANCE AND DECREASING ITS OUTPUT VOLTAGE.
