Abstract
A lead chloride cathode suitable for use in seawater batteries comprises a supporting electrically conductive grid to which lead chloride is applied by dipping the grid in a molten lead chloride bath. The grid is preferably made of mesh or expanded metal, and after allowing the lead chloride to solidify, a conductive matrix is formed in the cathode by inserting it in a salt solution and partially discharging it to form electrically conductive lead pathways within the cathode adjacent the points at which the grid material is closest to the surface and the grid itself. The preferred method comprises dipping the mesh or grid material in molten lead chloride, removing the grid and the adhering lead chloride, allowing the lead chloride to solidify, and partially discharging the cathode to form conductive lead portions.
