Abstract: A battery structure using cylindrically shaped zinc/air cells electrically connected in series, the cells being assembled so that a first number thereof are stacked in a first orientation in an in-line stack and a second number thereof are positioned adjacent the in-line stack in a second orientation perpendicular to the first orientation. The cells at the end of its series are connected to the anode and cathode terminals of a terminal board. The cell-terminal board assembly is inserted in a housing having nesting cavities into which portions of the cells are securely nested and a cover, affixed to the housing to form a battery container, has corresponding nesting cavities into which oppositely disposed portions of the cells are securely nested. Openings having blocking means associated therewith are provided at each end of the container to permit air to enter for interaction with the zinc in the cells but to prevent other objects from entering and making contact with the cells.

Abstract: The present invention relates to a lightweight auxiliary power supply utilizing a plurality of button cells, preferably of the zinc air type. The present invention contemplates a housing member containing a plurality of wells, each adapted to receive one or more disc shaped button cells; switch means to control the flow of oxygen to the cells; and electrical connecting means to suitably connect the power supply to the battery operated device or appliance.

Abstract: The disclosure describes a battery assembly which comprises several gas depolarizable electrochemical cells, e.g., metal/air cells, stacked electrically in series along a first dimension. Each cell has first and second electrodes of opposite polarities. The battery assembly also comprises a housing for containing the stack of cells. The housing includes a structure for ventilating the interior of the housing and further includes first and second opposite end walls which lie perpendicular to the first dimension. The stack of cells is arranged within the housing with the first electrode of the initial cell of the stack facing the first wall and the second electrode of the final cell of the stack facing the second wall. The battery assembly further includes first and second electrically conductive connectors disposed within the housing. The first connector has a first end electrically coupled to the first electrode of the initial cell and a second end disposed adjacent the first wall.

Abstract: The present invention relates to a portable electrical power source comprising housing means adapted to fit within a cell cavity of a battery-powered device, said housing means having positive and negative electrical contact means adapted to form electrical connection with corresponding positive and negative contact means of said device; a plurality of button cells disposed within said housing means, at least one of said button cells being electrically connected to said contact means and at least 50 percent of said button cells being insulated from any electrical connection to said contact means.
