Abstract

1421514 Electrodes for sea-water cells ESB Inc 9 Jan 1974 [26 April 1973] 01005/74 Heading H1B A cathode intended for use in a sea-water cell having a magnesium anode comprises lead chloride or cuprous chloride active material, carbon, and PTFE binder. The cathode may also include a hydrophilic water-soluble resin, e.g. polyethylene oxide, polyethylene glycol or polyvinyl pyrrolidone. Fig. 6 shows a flow diagram for the manufacture of a PbCl 2 active material cathode. In step 1, lead chloride, carbon and polyethylene oxide are fed to a kneader mixer and mixed at room temperature. In step 2 an aqueous emulsion of PTFE containing a wetting agent is added to the mixture in the kneader mixer and mixed therein at room temperature to obtain an elastic paste mass which is discharged in step 3 to a hopper. In step 4 the mass is fed to a mill maintained at 160‹ F. and formed into a sheet of desired thickness, this sheet having a rubbery malleable consistency. The sheet is further dried in step 5 in an oven at 110-210‹ F. In step 6 current collectors of copper mesh and the cathode sheet are cut to size and then laminated together by a calendarizing mill in step 7. The laminated electrodes are dried in an oven, step 8, at 160- 200‹ F. and then assembled into a battery, step 9.
