Battery

A battery including:

• first and second battery terminals configured for electrical communication with a load;
• a battery casing having first and second end portions and a chamber disposed therein;
• a first constituent, a second constituent, a solid spacer element, and at least one barrier arranged in a first configuration within the chamber, wherein the at least one barrier restricts the first constituent from interacting with the second constituent, wherein the solid spacer element comprises a disk-shape with an aperture disposed centrally and sized for a rod to fit therethrough, and the solid spacer element is positioned within the chamber between the first constituent and a permeable separator sheet, and
• whereby, responsive to a force being applied to a portion of the battery, the at least one barrier is configured for arrangement into a second configuration from the first configuration so that the first constituent and the second constituent are able to interact with each other to provide an electrolyte within the chamber,
• wherein the first constituent includes at least one of manganese dioxide, iron oxide, or crystalline silver oxide,
• wherein the chamber includes first and second compartments configured for containing the first and second constituents, respectively, wherein the second compartment is located adjacent to the second end portion of the battery casing, wherein:
• the at least one barrier includes a wall separating the first and second compartments;
• the wall separating the first and second compartments comprises a first rigid planar disc and a second rigid planar disc;
• the first rigid planar disc comprises a first plurality of holes and the second rigid planar disc comprises a second plurality of holes;
• the first plurality of holes and the second plurality of holes are non-aligned in the first configuration such that the first constituent is restricted from interacting with the second constituent;
• and
• the first plurality of holes and the second plurality of holes are aligned in the second configuration such that the first constituent and the second constituent are able to interact with each other.
