A striker mechanism including: a housing having a first surface; a slider movable in the housing, the slider having a projection or concavity, the slider having a second surface, the first and second surfaces defining an opening for a lanyard; a striker mass movably disposed relative to the housing, the striker mass having another of the projection and the concavity, the striker mass having a striker tip for engaging a primer; and a spring for biasing the striker tip relative to the housing. When the lanyard moves the slider within a first range of motion, the projection engages with the concavity to bias the striker mass towards the primer. When the lanyard moves the slider within a second range of motion, greater than the first range of motion, the projection disengages from the concavity allowing the striker mass to move towards the primer by a biasing force of the spring.

A metal-gas battery including: a battery core, gas container and a movable member. The battery core including a metal anode; a non-aqueous electrolyte; a porous cathode; and terminals for providing electrical power from the battery core. The gas container being configured to hold a pressurized gas. The movable member being configured to be movable from a non-activated position in which the pressurized gas in the container is sealed from entering the porous cathode and an activated position in which the pressurized gas flows into the porous cathode to activate the battery core.

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.

A reserve battery including: a housing has first and second compartments separated by a membrane, the first compartment has an anode and cathode and a separator positioned there between. The second compartment has an electrolyte for use with the anode and cathode to produce electrical power. The electrolyte being sealed in the second compartment relative to the first compartment at least by the membrane. Electrodes are connected to the anode and cathode and each has a portion on an outside of the housing. Where the second compartment has a cavity in which a wick material is arranged. The wick material is configured to pull the electrolyte into the second compartment from the first compartment by capillary action when the membrane changes from a sealed state in which the electrolyte is sealed within the second compartment to an unsealed state in which the electrolyte can flow into the first compartment.

The invention relates to an activation device for an electric battery unit, in particular, for a battery part of a torpedo. The invention also relates to a battery unit with activation devices of this type. An activation device incorporates an operating supply connection, to which an operating supply reservoir can be connected. A movably arranged cutting element can be pneumatically actuated via a pneumatic connection of the activation device by means of an actuation element, wherein a sealing element arranged in the path of travel of the cutting element controls the operating supply connection. In order to guarantee a safe storage, ready for operation, and a safe activation of a battery unit, it is provided in accordance with the invention that the activation device incorporates a pneumatic outlet, which can be fluidically connected to the pneumatic connection, depending on the position of the actuation element.
