Provided is an ampoule-type reserve battery including: an ampoule casing having an accommodation part formed therein; an electrolyte accommodated in a lower portion of the accommodation part; a leakage prevention liquid made of oil, which is phase-separated from the electrolyte without being mixed therewith so as to prevent the electrolyte from leaking through an upper portion of the accommodation part, and accommodated in the upper portion of the accommodation part; and a separation membrane mounted in the accommodation part and configured to separate the electrolyte from the leakage prevention liquid.

A liquid reserve battery including: a collapsible storage unit having a collapsible cavity for storing a liquid electrolyte therein; and a battery cell in communication with an outlet of the collapsible storage unit, the battery cell having gaps dispersed therein. Wherein the collapsible storage unit comprises a plurality of triangular sidewalls; and the plurality of triangular sidewalls being configured to collapse in a longitudinal direction about a hinge disposed between adjacent sides of each of the plurality of triangular sidewalls.

An electrochemical reactor includes positive and negative electrodes. A conductive and/or dielectric liquid is provided between the positive and negative electrodes. A first isolation member provided on the positive electrode isolates the positive electrode from the liquid, and a second isolation member provided on the negative electrode isolates the negative electrode from the liquid. The first and second isolation member each includes a liquid-repellent porous membrane. The reactor further includes a pressure-applying member which pressurizes the liquid to fill the pores of the first and second liquid-repellent porous membranes with the liquid, thereby causing an electrochemical reaction involving the positive and negative electrodes.

An activation device for a battery for an electronic ignition mechanism has an ampoule filled with an electrolyte and a device for breaking the ampoule. The breaking device contains two leaf spring elements, which are fixed with a prestress on a component in the housing interior and between which the ampoule is clamped. At least the leaf spring element which supports the ampoule on the bottom side snaps from a first shape into a second shape when a force due to acceleration is applied.

In some implementations, a metal air battery includes a body defined by a metal anode and a cathode, a first separator layer disposed on the metal anode, a second separator layer disposed on the cathode, and a plurality of beads disposed within the body. The beads may confine a liquid electrolyte, and may be configured to release the liquid electrolyte into interior portions of the battery in response to a compression of the cathode into the body of the battery.
