Abstract : A seawater cell contains an aluminum alloy anode having a potential of -.7 to -1.6 volts on the hydrogen scale, an electrolyte having one or more salts that are strong electrolytes when dissolved in water, and a cathode comprising a conductive grid and an active mixture. The active mixture contains manganese dioxide, inert conductive material and an adhesive binder. The active mixture is pressed onto the conductive grid to a condition of being porous to the electrolyte and providing good electrical conduction between all portions of the manganese dioxide and the conductive grid. The anode and cathode are immersed in the electrolyte to form the seawater cell. (Author)
