Abstract:

Cathodes were made from lead chloride mixed with a conductive carbon graphite, preferably with small additions of Shawinigan black. These dry mixes were blended with various synthetic rubber latexes in aqueous suspension, spread on an expanded metal grid, dried, and ultimately compressed to form the cathode. Of 16 latexes examined, UCAR 891 proved particularly suitable. Cathodes so made were assembled with magnesium alloy anodes to form single cells and discharged in dilute saline solutions. Discharge conditions were comparable to those for batteries used in the operation of passive sonobuoys. Performance resembled that of lead chloride cathodes made in other ways except at the low temperature low salinity extreme 0C, 1.5 NaC1 where low run voltages and slow rise to working voltage were observed. This problem must be overcome before application in sea water batteries can be considered. Author
