Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
69 words
IN A RESERVE BATTERY ADAPTED TO BE ACTIVATED BY IMMERSION IN A LIQUID ELECTROLYTE COMPRISING IN COMBINATION THEREWITH A BATTERY ELECTRODE-SEPARATOR ASSEMBLY COMPRISING A PLATE-LIKE ELECTRODE HAVING A PLURALITY OF PERFORATIONS THEREIN, A LAYER OF INSULATING MATERIAL ON ONE SURFACE OF SAID ELECTRODE, AND A PLURALITY OF INSULATING SPACERS PROJECTING FROM THE OTHER SURFACE THEREOF, SAID SPACERS COMPRISING MATERIAL FROM SAID LAYER EXTENDING THROUGH THE PERFORATIONS IN SAID ELECTRODE.
Claim 2
Dependent Claim
69 words
IN A RESERVE BATTERY ADAPTED TO BE ACTIVATED BY IMMERSION IN A LIQUID ELECTROLYTE COMPRISING IN COMBINATION THEREWITH A BATTERY ELECTRODE-SEPARATOR ASSEMBLY COMPRISING A PLATE-LIKE ELECTRODE HAVING A PLURALITY OF PERFORATIONS THEREIN, A LAYER OF INSULATING MATERIAL ON ONE SURFACE OF SAID ELECTRODE, AND A PLURALITY OF INSULATING SPACERS PROJECTING FROM THE OTHER SURFACE THEREOF, SAID SPACERS COMPRISING MATERIAL FROM SAID LAYER EXTENDING THROUGH THE PERFORATIONS IN SAID ELECTRODE.
Claim 3
Dependent Claim
129 words
A CELL ASSEMBLY FOR A RESERVE BATTERY OF THE TYPE ADAPTED TO BE ACTIVATED BY IMMERSION IN A LIQUID ELECTROLYTE COMPRISING, A SUB-ASSEMBLY COMPRISING A PAIR OF COMPLEMENTARY ELECTRODE COMPARTMENTS FORMED OF AN INSULATING MATERIAL AND JOINED BY A HINGE, A PAIR OF PERFORATED ELECTRODES BOTH OF THE SAME POLARITY AND EACH HOUSED IN A SEPARATE ONE OF SAID COMPARTMENTS, THE INSULATING MATERIAL OF SAID COMPARTMENTS PROJECTING THROUGH THE PERFORATIONS IN THE ELECTRODE THEREIN TO FORM A PLURALITY OF SPACERS ON THE SURFACE OF SAID ELECTRODE, ELECTROLYTE PORTS IN SAID COMPARTMENTS, AND AN ELECTRODE OF THE OPPOSITE POLARITY, SAIS SUB-ASSEMBLY BEING FOLDED AT SAID HINGE AROUND SAID ELECTRODE OF OPPOSITE POLARITY TO FORM A CELL CONTAINER IN WHICH SAID ELECTRODES ARE HELD IN A SPACED RELATIONSHIP BY SAID SPACERS.
