1. A battery including:
a battery casing defining a chamber therein, said casing including at least a first portion and a second portion that are movable relative to each other between at least a first configuration and a second configuration;
an anode and cathode terminal;
an compressed electrolyte powder disposed in the chamber; and
an envelope disposed within the chamber which releasably seals a liquid therein;
wherein responsive to movement of the first portion relative to the second portion from the first configuration into the second configuration, the envelope disposed within the chamber is configured to be unsealed and to release the liquid in the chamber in to contact with the electrolyte power so to activate the electrolyte powder whereby a potential difference is able to be generated between the anode and cathode terminals of the battery; and
wherein the compressed electrolyte powder includes a substantially ring-shaped configuration having an outer peripheral surface and an inner peripheral surface defining a hollow core.
