  • Patent number: 8088519
    Abstract: Battery cartridges are disclosed that include a housing having a plurality of air access openings configured to selectively control flow of air into the housing; and at least two adjacent metal-air electrochemical cells within the housing, each electrochemical cell having an outer gas permeable barrier membrane layer that defines the exterior surface of the electrochemical cell; wherein there is a gap between adjacent electrochemical cells in the housing and wherein the air access openings in the housing are positioned over or partially overlapping each gap.
    Type: Grant

  • Publication number: 20100178540
    Abstract: A non-hermetically sealed, electrochemical power source, includes a first electrode, a second electrode, a separator between the first electrode and the second electrode, and a membrane in fluid communication with an environment external to the battery. The second electrode is between the separator and the membrane. The membrane includes a first portion having a different property, e.g., density, porosity, mass transport resistance, thickness, or gas permeability, than a second portion of the membrane. Methods of designing an electrochemical cell cartridge are also disclosed.

  • Patent number: 7704621
    Abstract: A battery includes a cathode having an interior surface and an exterior surface, and defining a cavity and two open ends; a separator disposed adjacent to the interior surface of the cathode; an anode disposed adjacent to the separator and inside the cavity; an air-permeable, liquid-impermeable barrier layer disposed adjacent to the exterior surface of the cathode, and defining an exterior surface of the battery; two end members connected to the open ends of the cathode; and an anode current collector extending through the two end members. Methods designed such a battery is also disclosed.
