Battery

摘要

A body has a liquid-activatable powder mixture disposed in a metal casing with a first end that extends towards a second end longitudinally and includes at least one perforation, a conductive rod with a first end located adjacent and beyond the first end of the metal casing and extends towards the second end in contact with the powder mixture, a permeable separator, disposed between the liquid-activatable powder mixture and the metal casing, for electrically isolating the negative electrode from the positive electrode while being permeable to liquid useful in activating the powder mixture, and a passage, extending from the perforation of the metal casing through the permeable separator, for allowing a flow of liquid to activate the liquid activatable powder mixture. The metal casing is moveable relative to at least the body between a first position to expose and a second position to conceal the perforation on the metal casing.

主权项

1. A battery comprising:
a body having opposite first and second ends; a liquid-activatable powder mixture disposed in the body; a negative electrode, at which anions are oxidized, comprising a metal casing which has a first end that extends towards a second end longitudinally and includes at least one perforation; a positive electrode, to which cations migrate, comprising a conductive rod which has a first end located adjacent and beyond the first end of the metal casing and that extends towards the second end of the body in contact with the powder mixture; a permeable separator, disposed between the liquid-activatable powder mixture and the metal casing, for lining the perforation and electrically isolating the negative electrode from the positive electrode while being permeable to liquid useful in activating the powder mixture; and a passage, extending from the perforation of the metal casing through the permeable separator, for allowing a flow of liquid to activate the liquid activatable powder mixture, wherein the metal casing is moveable relative to at least the body between a first position to expose and a second position to conceal the perforation on the metal casing.
