Abstract: AN INEXPENSIVE AND SIMPLY CONSTRUCTED BATTERY, HAVING GOOD STORAGE PROPERTIES PRIOR TO USE. THE BATTERY IS COMPRISED OF AN ANODE, CATHODE, AND A SEPARATOR LOCATED WITHIN A FIRST PLASTIC POUCH. ALSO WITHIN THE FIRST POUCH IS A SECOND INNER POUCH CONTAINING A SOLUTION OF ELECTROLYTE CHEMICALS. FOR ACTIVATION OF THE BATTERY THE INNER POUCH IS RUPTURED, THEREBY BRINGING THE ELECTROLYTE INTO CONTACT WITH THE REMAINING ACTIVE ELEMENTS OF THE BATTERY. A PROTION OF THE OUTSIDE POUCH IS FORMED OF A GAS PERMEABLE MEMBRANE TO ALLOW DISSIPATION OF GAS AND THEREBY PREVENT BURSTING OF THE BATTERY. TO PREVENT OR MINIMIZE THE LIKELIHOOD OF DIRECT CONTACT BY THE LIQUID ELECTROLYTE WITH THE PERMEABLE MEMBRANE, A LABYRINTH COMPRISED OF A PAIR OF OVERLAPPING BAFFLES IS INTERPOSED BETWEEN THE BATTERY AND THE PERMEABLE MEMBRANE.
