Reserve battery having the electrolyte compartment moved by gas pressure
Abstract
Abstract AN IMPROVED ACTIVATOR MECHANISM FOR A RESERVE ELECTROCHEMICAL BATTERY. THE BATTERY IS COMPRISED OF AN ELECTROLYTE COMPARTMENT AND A BATTERY COMPARTMENT SEPARATED FROM THE ELECTROLYTE COMPARTMENT BY A FRANGIBLE DIAPHRAGM. TO ACTIVATED THE BATTERY, THE DIAPHRAGM, SEP ARATING THE TWO COMPARTMENTS, IS PERFORATED, ALLOWING ELECTORLYTE LIQUID TO FLOW FROM THE ELECTROLYTE COMPARTMENT INTO THE BATTERY COMPARTMENT. THE ELECTROLYTE COMPARTPARTMENT IS DIVIDED INTO TWO PARTS BY A MOVABLE PARTITION. THE PORTION OF THE COMPARTMENT BETWEEN THE MOVABLE PARTITION AND THE FRANGIBLE DIAPHRAGM IS FILLED WITH A LIQUID ELECTROLYTE. THE OTHER PORTION OF THE COMPARTMENT ON THE OTHER SIDE OF THE MOVABLE PARTITION IS FILLED WITH A GAS UNDER PRESSURE. A SMALL AMOUNT OF ELCTROLYTE LIQUID IS ALSO PLACED ON THE GAS PRESSURE SIDE OF THE MOVABLE PARTITION TO EQUALIZE AND CANCEL THE EFFECT OF THE VAPOR PRESSURE OF THE ELECTROLYTE SOLVENT ON BATTERY ACTIVATION.
