  • Easy refuelling metal-gas cell battery with soft pocket
    Patent number: 6844096
    Abstract: A metal-gas cell battery, such as a zinc-air cell battery, has one or more metal-gas cells. Each metal-gas cell has a metal anode sandwiched between a pair of gas cathodes. Each gas cathode is disposed within a rigid retaining structure. An expandable soft pocket for holding an electrolyte connects the two retaining structures. The anode is disposed within the soft pocket without being enclosing by a separator bag. The cell is mechanically refueled by expanding the soft pocket to allow replacing easily a spent anode with a fresh anode.
