Liquid-activatable battery

A battery including:

• a casing defining a first end and a second end and having an inner surface defining a chamber in which an electrolyte is disposed therein;
• a conductive lining disposed within the chamber adjacent the inner surface of the casing, the conductive lining being configured for electrical communication with a first battery terminal at the second end of the casing;
• a permeable separator sheet disposed between the electrolyte and the conductive lining;
• a conductive rod having a first end configured for electrical communication with a second battery terminal, and, a second end configured for contacting with the electrolyte;
• an opening disposed in the casing;
• a sealing member configured for arrangement between at least a sealed position which restricts ingress of a liquid into the chamber via the opening, and, an unsealed position which allows ingress of a liquid into the chamber via the opening and into contact with the electrolyte so as to allow a potential difference to be produced between the first and second battery terminals;
• at least one spacing element configured for spacing the electrolyte apart from the conductive lining within the chamber whereby the liquid is able to pass between the electrolyte and the conductive lining;
• further including a silicone pad at the first end of the casing for urging the conductive lining and the first battery terminal into electrical communication with each other at the second end of the casing;
• and
• wherein the casing includes an electrically-insulative, polymeric material made of at least one of a copolymer, a mixed polymer blend, a thermoplastic material, a thermoset material, PE, PP, PVC, PVA, EVA, PEEL, PMMA, PTFE and any combination thereof.
