Thirteen different materials were checked for their reaction towards silver oxide dissolved in potassium hydroxide solutions. Of these, the polyethylenes appear to have most promise as separator materials. Several attempts were made to trace the migration of silver in a silvercadmium cell by the use of radioactive silver. A method of counting the radioactivity is being developed. The main difficulty encountered in this study is the take-up of radioactive silver by the electrodes. This has obscured the interpretation of the results obtained to date. (Author).
