Pressure activated reserve battery
Patent
·
OSTI ID:6305345
A reserve pressure compensating battery is described comprising at least one reserve cell which contains a mean for storing a pair of cell electrodes and an electrolyte reservoir, separated by a fluid-tight barrier. It also includes a first rupturable seal means for providing a rupturable fluid tight barrier between the cell electrodes and the cell electrolyte reservoir, a second rupturable seal means across an external end of the cell electrolyte reservoir means, a deformable cup means within the electrolyte reservoir which provides a fluid-tight seal, a housing means surrounding the reserve cell and having an opening therein, a third rupturable seal means across the opening in the housing means, a flexible bladder means in the housing means for isolating the third seal means from the second seal means, and an electrically nonconductive fill fluid within the housing means between the bladder means and the second seal means whereby a movement of the bladder means allows an internal pressure of the fill fluid to match an external environmental pressure to minimize pressure resistance to the housing means.
