Water-acivated storage battery

A water-activated battery, stored in a dry condition and activated at the time of use by the addition of a conductive aqueous solvent, comprising:

• a battery casing defining a chamber, said battery casing having a liquid entry port formed therein for allowing conductive liquid into said chamber;
• a cathode member disposed in said chamber;
• an anode member disposed in said chamber;
• and
• spacer members attached to said housing and rigidly spacing said cathode member from said anode member and from the bottom of the chamber.

A water-activated battery, stored in a dry condition and activated at the time of use by the addition of a conductive aqueous solvent, comprising:

• a battery housing;
• a cathode disposed in said housing, said cathode including a chloride member having a surface and a silver coating disposed on said surface;
• an anode disposed in said housing spaced apart from said cathode, said anode including a magnesium member;
• at least one spacer fixed in said battery housing separating said chloride member from said magnesium member and from the bottom of the housing;
• and
• a conductive aqueous solvent retained in said housing in contact with said chloride member and said magnesium member.

A method of operating a water-activated battery, stored in a dry condition and activated at the time of use by the addition of a conductive aqueous solvent, comprising a cathode member, an anode member, spacers spacing said cathode member from said anode member and from the bottom of the housing, a battery housing enclosing the cathode member and the anode member, the battery housing being formed with a liquid entry port initially closed with a entry port plug and a liquid exit port initially closed With an exit port plug,

• the method which comprises:
• immersing the initially dry battery in a conductive aqueous solvent,
• removing the entry port plug from the entry port to permit conductive aqueous solvent to enter the housing through the entry port,
• removing the exit port plug from the exit port to permit the conductive aqueous solvent to exit the housing through the exit port.
