<p>A battery including: a metal tube having opposed first and second ends, and an inner peripheral surface defining a chamber in which a liquid-activatable powder mixture is disposed therein; a permeable separator sheet for electrically isolating the powder mixture from the metal tube; a conductive rod having a first end located adjacent the first end of the metal tube and extending to a second end in contact with the powder mixture; and a passage extending between the first and second opposed ends of the metal tube to allow flow of liquid therethrough, wherein said liquid is able to be delivered from the passage into contact with the powder mixture via the permeable separator sheet substantially along the length of the metal tube so as to activate the powder mixture, whereby the activated powder mixture is adapted to generate a potential difference between the conductive rod and the metal tube.</p> |
