Auxiliary electrodes attached to AgO electrodes through a diode in a test cell appear to eliminate excessive pressures occurring through H2 liberation. The use of acicular needle-like particle shapes of zinc-oxide are detrimental to cycle life. The zinc-oxide KADOX-15 appears to be most satisfactory for use in cells in this program. The repeat tests on surfactants using 1, 3, 5 additions in the negative material indicate that additions larger than 1 are detrimental to cell performance. A new cell case and cover mold is completed, and test units of Celcon moldings are being prepared for heat sealing techniques. Author
