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.
