Abstract
Abstract An electrode pouch for use in a reserve battery has a flexible containment wall with first and second side wall portions defining between them a fluid impervious, electrolyte chamber. Preferably each of the side wall portions has a carrier layer of a sealable plastic material and a bonded overlying fluid barrier layer formed of a metal electrode material. The electrode pouch construction enables rapid and inexpensive manufacture at high production rates by conventional plastic film and sheet packaging equipment. The pouch is used in combination with other pouches or by itself in various battery constructions. Such batteries include means for piercing the pouch through the metal and plastic layers to release the electrolyte and activate the battery.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
78 words
A RESERVE BATTERY CONSTRUCTION COMPRISING, A POUNCH FORMED OF A FIRST THIN OUTER LAYER OF A METALLIC ELECTRODE MATERIAL AND A SECOND THIN INNER LAYER OF A SEALABLE PLASTIC, SAID POUNCH ENCLOSING AN ELECTROLYTE, MEANS FOR PIERCING SAID POUNCH THROUGH SAID METAL AND PLASTIC LAYERS TO RELEASE SAID ELECTROLYTE AND ACTIVATE SAID BATTERY, A SECOND ELECTRODE, AND A POROUS SEPARATOR BETWEEN SAID METAL LAYER AND SAID SECOND ELECTRODE WHEREBY ACTIVATION OF SAID PIERCING MEANS ACTIVATES SAID RESERVE BATTERY
Claim 2
Dependent Claim
78 words
A RESERVE BATTERY CONSTRUCTION COMPRISING, A POUNCH FORMED OF A FIRST THIN OUTER LAYER OF A METALLIC ELECTRODE MATERIAL AND A SECOND THIN INNER LAYER OF A SEALABLE PLASTIC, SAID POUNCH ENCLOSING AN ELECTROLYTE, MEANS FOR PIERCING SAID POUNCH THROUGH SAID METAL AND PLASTIC LAYERS TO RELEASE SAID ELECTROLYTE AND ACTIVATE SAID BATTERY, A SECOND ELECTRODE, AND A POROUS SEPARATOR BETWEEN SAID METAL LAYER AND SAID SECOND ELECTRODE WHEREBY ACTIVATION OF SAID PIERCING MEANS ACTIVATES SAID RESERVE BATTERY
Claim 3
Dependent Claim
34 words
A reserve battery construction in accordance with claim 1 and further comprising, said outer and inner layers being formed from a laminated film, spring means for biasing said second electrode toward said electrode pouch.
Claim 4
Dependent Claim
48 words
A reserve battery construction in accordance with claim 2 and further comprising, rigid end plate means on either side of said electrode pouch and second electrode, and gasket means positioned between said end plate means for containing electrolyte released from said pouch by activation of said piercing means.
Claim 5
Dependent Claim
24 words
A reserve battery construction in accordance with claim 1 wherein said pouch is in the form of a molded cup having an enclosing lid.
Claim 6
Dependent Claim
19 words
A reserve battery construction in accordance with claim 1 wherein said second thin inner layer completely encloses said electrolyte.
Claim 7
Dependent Claim
32 words
A reserve battery construction in accordance with claim 3 and further comprising said end plate means on one side of said electrode pouch comprising the base board of a printed circuit board.
Claim 8
Dependent Claim
20 words
A reserve battery construction in accordance with claim 5 wherein said first thin outer layer partially covers said inner layer.
Claim 9
Dependent Claim
16 words
A reserve battery construction in accordance with claim 5 wherein said separator mounts said piercing means.
Claim 10
Independent Claim
91 words
A method of activating a reserve battery construction having an electrode pouch formed of a first thin layer of a metal and a second thin layer of a plastic enclosing an electrolyte with the metal layer being capable of acting as an electrode, a second electrode spaced from said first electrode, and an insulating separator between said first and second electrodes, said method comprising activating a piercing means to pierce said metal and plastic layers of said pouch to cause said electrolyte to flow between said electrodes and activate said battery.
Claim 11
Independent Claim
91 words
A method of activating a reserve battery construction having an electrode pouch formed of a first thin layer of a metal and a second thin layer of a plastic enclosing an electrolyte with the metal layer being capable of acting as an electrode, a second electrode spaced from said first electrode, and an insulating separator between said first and second electrodes, said method comprising activating a piercing means to pierce said metal and plastic layers of said pouch to cause said electrolyte to flow between said electrodes and activate said battery.
Claim 12
Dependent Claim
42 words
A method in accordance with the method of claim 9 and further comprising resiliently urging said first and second electrodes toward each other after actuating said piercing means to obtain a smooth, continuous electrical output over the active life of said battery.
