ABSTRACT:
A battery cell of extended shelf life, which has a separate electrolyte storage tank having screened outlet ports, which tank is mounted within another container to define an annulus therebetween, which annulus defines a passageway to a screened outlet port and thence to a battery cell, is provided. The screens are of fine mesh size which pass electrolyte therethrough but due to the surface tension of the electrolyte entrained therein, block the passage of gas therethrough and thus separate the two. Such battery is dormant until the electrolyte is expelled from the storage tank through the annulus, through the conduit and into the battery. In an improvement, such electrolyte is expelled by charging pressurized gas to the storage tank which expels the electrolyte through the tank barrier screens to the annulus, through the outlet port barrier screens to such battery cell while retaining the pressurized gas in the storage tank and perhaps a small amount of such gas behind the outlet port barrier screens to thus exclude the passage of gas into such battery cell, which gas can impair the operation thereof. The pressure drop across such screens is controlled or held below a certain level to stop or minimize gas bubble penetration through such screens.
