An activation mechanism for a battery for an electronic ignition mechanism contains an ampoule filled with an electrolyte. The mechanism for breaking has a snap spring element to which the ampoule is attached in a freely suspended manner. The snap spring element snaps from a first shape into a second shape when a force due to acceleration is applied, thereby severing the attachment of the ampoule.

A battery includes a battery casing defining a chamber therein, and an electrolyte powder disposed in the chamber. The electrolyte powder is configured to surround a zinc material that is separated from the electrolyte powder by a permeable separator sheet. The battery also includes a conductive member having a first end configured for electrical communication with an anode terminal of the battery, and, a second end configured for electrical communication with the zinc material. A conductive layer is also disposed between an inner surface of the casing and the electrolyte powder, the conductive layer being configured for electrical communication with a cathode terminal of the battery. There is also a liquid release mechanism configured for allowing release of a liquid in the chamber to activate an ion flow between the electrolyte powder and the zinc material via the permeable separator sheet.

Provided is an assembled battery in which a large number of flat batteries can be stacked easily. An assembled battery 1 includes stacked multiple flat batteries A, B, and C in the shape of an N-sided polygon (N is an integer of 3 or more). Each of the multiple flat batteries A, B, and C in the shape of the N-sided polygon has a positive-electrode terminal 21a and a negative-electrode terminal 61a that extend in different directions having 360°/N in between, and the multiple flat batteries A, B, and C are electrically connected in series. The assembled battery 1 also includes multiple N-sided polygonal separating films 71 and 72 disposed between each pair of adjacent ones of the stacked multiple flat batteries A, B, and C to insulate the flat batteries from one another.

Disclosed is a flexible battery made of a cathode comprising printable graphite, the cathode positioned on a first side of a paper; an anode comprising aluminum on a second side of the paper; an aqueous electrolyte comprising water and an aluminum halide, the aqueous electrolyte saturated within the paper; and an encapsulating film surrounding the anode and cathode.

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.
