Improved separators for silver oxide-zinc and silver oxide-cadmium cells for spacecraft applications. Quarterly progress report 1, November 10, 1964-February 9, 1965. [Diffusion of Ag oxides]
A study was made of the diffusion of silver oxide through separator membranes, by use of radioactive silver and an improved technique. Three different types of membrane behavior were found: (1) membranes composed of methyl cellulose intimately mixed with carboxylated polymers took up only very small amounts of silver but allowed small amounts of silver oxide to diffuse through. (2) Membranes composed of cellophane or polyvinyl alcohol, or compositions containing large amounts of hydroxyethyl cellulose reduce considerable amounts of silver oxide to metallic silver, allowing relatively small amounts to pass through. (3) A film of S-type polymer developed under another project was unique in that it showed very little tendency either to pick up silver or let it pass through.
