Abstract
A lithium-bromine cell comprising a casing which can be of electrically conducting material and containing a lithium anode element from which a sealed conductor extends through the casing. A filling element which can be of electrically conducting material and which has a passage therethrough is fixed to the sealed casing with one end of the passage in communication with the interior of the casing and the other end externally exposed. Bromine is introduced through the passage to the interior of the casing into operative relationship with the lithium anode whereupon the passage is closed to complete the cell. The electrically conducting casing serves as a cathode current collector in operative contact with the bromine cathode, and after closing of the passage the electrically conducting filling element serves as an electrical terminal for the cell. An electrical potential difference exists between the terminal and the anode conductor during operation of the cell.
