摘要： A ventilation system for one or more metal-air cells includes a distributor for uniformly distributing oxygen between oxygen electrodes in response to operation of an air moving device. The distributor may be further operative, or associated with one or more restrictive passageways that are operative, while unsealed to provided a barrier function that protects the metal-air cells from the ambient environment while the air moving device is not operating. The perforated member defines a plurality of apertures that at least partially define the reactant air flow path through which air is supplied to the metal-air cells. The perforated member may be a plate or an elongate ventilation passageway, such as a tube. The metal-air cells may be arranged in a stack, and a first of the apertures is more proximate to a first plenum defined between the cells than a second plenum defined between the cells, and a second of the apertures is more proximate to the second plenum than the first plenum. The air moving device may be mounted between protrusions of the cells. Each cell case may include a pair of unitary case portions, each of which has side walls extending from a panel in a common direction to define a cavity. For each cell, the side walls of a first case portion extend into the cavity of a second case portion.

摘要： A primary metal-air power source containing one or more metal-air cells incorporating an air manager in a power source housing of the power source. The power source provides intermittent use at high power levels over a long lifetime while demonstrating a high utilization of the metal, such as zinc, making up the metal-air cell's metal anode. The power source provides 80 % of its amp hour capacity for at least 30 days after the initial partial discharge at a power level of at least 50 milliwatts. The cumulative run time may comprise any number of intermittent connections to a load having varying duration. The ventilation system of the power source draws ambient airflow through an isolating passageway by operating an air mover which distributes the airflow to the metal-air cells. A portion of the airflow is recirculated by the air mover and returned to the metal-air cells and the remaining portion of the airflow is moved through a second isolating passageway to the exterior of the power source's power source housing. The movement of airflow into and out of the power source is minimized during in-service storage.

摘要： Provided are metal-air cells for connecting to one another to form a battery stack. Two or more of the cells are joined by heat or chemical fusing to create the battery stack. Each of the metal-air cells have a case with an exterior surface and an interior surface that defines a chamber that contains an anode and an air cathode. The case defines air openings that extend between the exterior surface and the interior surface for supplying air from the environment exterior to the case to the air cathodes within the chamber. In one embodiment, each metal-air cell includes a plurality of protruding connector members and a plurality of protruding mechanical stops. Two cells are joined by fusing connector members of one cell to connector members of the other cell. During the fusing of the connector members, the mechanical stops of the cells being joined abut one another to arrest movement of the cells toward one another. The arresting causes a plenum to be uniformly defined between the cells. The fused connector members and abutting mechanical stops cooperate to define a three-dimensional truss-like system that provides structural integrity. In an alternative embodiment, at least one of the two metal-air cells to be joined includes a plurality of connectors and is otherwise free of stops. These connectors can be aligned with and fused to similar connectors on the other cell or be fused directly to the exterior surface of the other cell. Connector members and mechanical stops are preferably integrally formed with their case and interspersed with the air openings.

摘要： An air manager system is disclosed which maintains a more stable water vapor and carbon dioxide equilibrium across the air cathode of a metal-air cell while still providing new oxygen needed for operation of the cell at desired power levels. Oxygen is preferentially drawn in through one or more ventilation openings (17) in a housing (15), so that the concentrations of water vapor and carbon dioxyde in the battery housing remain more stable, resulting in less transfer across the cathode (30). A fan (20) circulates the gases within the battery housing, keeping the oxygen needed for operation of the cell in contact with the air cathode even though the oxygen concentration within the housing is reduced compared to the ambient air outside the housing. Therefore, the cell is less susceptible to drying out or flooding, and less carbon dioxyde intrudes into the cell.

摘要： A ventilation system for a metal-air battery having a housing for enclosing at least one metal-air cell (10). The housing (20) has at least one air inlet opening (30) and at least one air outlet opening (35). A fan (40) is positioned to force air into the air inlet opening and out of the air outlet opening when the fan is turned on. The openings are sized with a length in the direction through the thickness of the housing being greater than a width in the direction perpendicular to the thickness of the housing. The openings are unobstructed and are sized to eliminate substantially the air flow into the air inlet opening and out of the air outlet opening when the fan is turned off. According to another aspect of the invention, a fan (80) within the battery housing (72) is positioned to distribute air to two separate sets (76-79) of metal-air cells at the same time. In this configuration, all cells of both sets of cells receive air quickly, and the air received is richer in oxygen because the air paths are shorter than in previous configurations utilizing the same number of cells.

摘要： A vent system (10) for exhausting gas generated within a battery case (12) is provided. The vent system exhausts gas from the battery case while maintaining the hermetic seal of the case. The vent system provides a small gas exit hole (16) that is sufficiently small to prevent electrolyte leakage and also intake of excess carbon dioxide or excess water vapor from the atmosphere. Also, various combinations of gas-permeable, hydrophobic membranes (40, 44) and diffuser material (42) may cover the gas exit hole (16) to provide humidity control for the battery while exhausting gases from the battery. A recess (36) may be provided within the case such that the gas exit hole communicates between the atmosphere and the recess. Also, various combinations of gas-permeable, hydrophobic membranes and diffuser material may cover the recess and gas exit hole to provide humidity control for the battery while exhausting gases from the battery case. The present invention also provides a vent system in which gas-permeable, hydrophobic membranes and diffuser material may fill an opening so as to exhaust gas from the case. The present invention also provides an electrode lead (33) which extends along the battery case and through the seam (34) of the battery case in a manner in which a hermetic seal is provided around the lead. The manufacturing process for the seal around the lead is relatively simple.
