Miniature Reserve Battery Arrays and Stand-Alone For Munitions and the Like

A reserve battery comprising:

• a substrate having a plurality of openings defining a cavity;
• and
• a reserve battery provided in each of the plurality of openings, each of the reserve batteries comprising:
• an anode and a cathode disposed in a first portion of each of the plurality of openings;
• a separator positioned between the anode and cathode disposed in each of the plurality of openings;
• an electrolyte disposed in a second portion of each of the plurality of openings, the electrolyte being for use with the anode and cathode to produce electrical power, the electrolyte being sealed in the second portion relative to the first portion at least by a membrane separating the first and second portions;
• electrodes connected to the anode and cathode, each having a portion on an outside of the substrate;
• wherein the second portion having a wick material, the wick material being configured to pull the electrolyte into the second portion from the first portion by capillary action when the membrane changes from a sealed state in which the electrolyte is sealed within the second portion to an unsealed state in which the electrolyte can flow into the first portion.

A munition comprising:

• a reserve battery comprising:
• a housing having first and second compartments separated by a membrane,
• the first compartment having an anode and cathode and a separator positioned between the anode and cathode;
• the second compartment having 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 connected to the anode and cathode each having a portion on an outside of the housing;
• wherein the second compartment having cavity in which a wick material is arranged, the wick material being 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.
