  • BATTERY SEPARATOR
    Publication number: 20080206632
    Abstract: An alkaline battery includes a housing, a cathode disposed within the housing, an anode disposed within the housing, a separator disposed between the anode and the cathode, and an alkaline electrolyte contacting the anode and the cathode. The separator can include a tube having at an inner tube layer and an outer tube layer. The inner tube layer is disposed radially inward from the outer tube layer and no portion of the inner tube layer is disposed radially outward from any portion of the outer tube layer. The separator can also include a disc positioned at one end of the tube to create a closed end of the separator.
