Method of making primary metal air batteries

Abstract

Abstract A METHOD OF MANUFACTURING A PRIMARY METAL-AIR BATTERY COMPRISES STARTING WITH A PLURALITY OF ELECTRICALLY CONNECTED METAL-AIR BATTERY CELLS, EACH OF WHICH INCLUDES A PAIR OF ELECTRICALLY CONNECTED AIR ELECTRODES POSITIONED ON OPPOSITE SIDES RESPECTIVELY OF A METAL ANODE AND INSULATED THEREFROM. EACH AIR ELECTRODE INCLUDES CATALYST MATERIAL SUPPORTED ON A SHEET OF POROUS MATERIAL, WITH EACH PAIR OF SHEETS OF POROUS MATERIAL BEING JOINED TOGETHER AT THEIR PERIPHERIES TO DEFINE A CELL COMPARTMENT, AND WITH A REMOVABLE PIN EXTENDING INTO EACH CELL COMPARTMENT AND PROJECTING FROM THE PERIPHERIES OF THE PAIR OF SHEETS DEFINING THE RESPECTIVE CELL COMPARTMENT. THE CELLS ARE POSITIONED IN A MOULD WITH THE REMOVABLE PINS BEING RECEIVED IN RESPECTIVE HOLES IN THE MOULD AND A SETTABLE COMPOUND IS INTRODUCED INTO THE MOULD. THE COMPOUND IS THEN ALLOWED TO SET SO AS TO FORM A BODY EXTENDING BETWEEN AND JOINING ADJACENT CELLS, AND THE PINS ARE REMOVED FROM THEIR RESPECTIVE CELLS SO AS TO LEAVE APERTURES IN THE BODY THROUGH WHICH ELECTROLYTE CAN BE INTRODUCED INTO THE CELL COMPARTMENTS RESPECTIVELY OF THE BATTERY.
