Patent ID: 6844096

Claim:
A metal-gas cell battery comprising (a) at least one metal-gas cell comprising: a first retaining structure and a second retaining structure aligned parallel, the second retaining structure being moveable with respect to the first retaining structure between a first retaining structure position, wherein the second retaining structure is proximate to the first retaining structure, and a second retaining structure position, wherein the second retaining structure is spaced apart from the first retaining structure; a first gas cathode disposed within the first retaining structure, the first gas cathode being permeable to gases but impermeable to liquids, the first gas cathode allowing the passage of gases into the cell; a second gas cathode disposed within the second retaining structure, the second gas cathode being permeable to air but impermeable to liquids, the second gas cathode allowing the passage of gases into the cell, and the second gas cathode being electrically connected to the first gas cathode; a soft pocket disposed between the first gas cathode and the second gas cathode, the soft pocket having a flexible and planar first wall and a flexible and planar second wall, a periphery of the first wall including a top edge, a periphery of the second wall including a top edge, the periphery of the first wall being connected to the periphery of second wall except along the respective top edges, the periphery of the first wall being attached to the first retaining structure and the periphery of the second wall being attached to the second retaining structure, whereby the first retaining structure, the first gas cathode, the first wall, the second wall, the second retaining structure and the second gas cathode cooperate to define a liquid retaining soft pocket chamber having a lower portion, an upper portion and a top opening defined between the top edges of the first and the second walls, the top opening being open when the first and the second retaining structures are in the second retaining structure position and tightly closed when the first and the second retaining structures are in the first retaining structure position; a soft pocket closing mechanism for securing the first and the second retaining structures in the first retaining structure position; a metal anode disposed within the soft pocket chamber; a first protective mesh disposed between the first gas cathode and the first wall of the soft pocket, and a second protective mesh disposed between the second gas cathode and the second wall of the soft pocket; and a first separator sheet is permanently installed between the first gas cathode and the first protective mesh, and a second separator sheet is permanently installed between the second gas cathode and the second protective mesh; and (b) a positive battery terminal electrically connected to the first and the second gas cathodes; and (c) a negative battery terminal electrically connected to the metal anode.
