<p>A battery includes a metal tube (2) having opposed first (2a) and second ends (2b); an inner peripheral surface (2c) defining a chamber in which a liquid-activatable powder mixture (11) is disposed; a permeable separator sheet (9) for electrically isolating the powder mixture (11) form the metal tube (2); a conductive rod (5) having a first end located adjacent the first end (5a) of the metal tube and extending to a second end (5b) in contact with the powder mixture; and a passage extending between the first and second opposed ends of the metal tube (2) to allow flow of liquid therethrough, wherein the liquid is able to be delivered from the passage to contact with the powder mixture via the permeable separator sheet (9) substantially along the length of the metal tube (2) so as to activate the powder mixture (11), whereby the activated powder mixture is adapted to generate a potential difference between the conductive rod (5) and the metal tube (2).</p> |
