Claim Text:
1. A liquid reserve battery, the liquid reserve battery comprising: a collapsible storage unit having a liquid electrolyte stored therein; a battery cell in communication with an outlet of the collapsible storage unit, the battery cell having gaps dispersed therein; a pyrotechnic material disposed adjacent the collapsible storage unit such that initiation of the pyrotechnic material provides pressure to collapse the collapsible storage unit to heat and force the liquid electrolyte through the outlet and into the gaps; and at least one vacuum generating element for drawing gases from the gaps in the battery cell; wherein the vacuum generating element comprises an elastically deformable container, one or more releasing members to retain the elastically deformable container in a deformed configuration having a first volume and at least one sealed outlet in communication with the battery cell; and the one or more releasing members comprises one or more burnable fibers which are released by the initiation of the pyrotechnic material to allow the elastically deformable container to elastically deform to have a second volume greater than the first volume to thereby draw gases from the battery cell through the sealed outlet.
