SILVER-ZINC ELECTRODES AND SEPARATOR RESEARCH.
Abstract
A proprietary phenolic membrane with the methacrylic acid graft gives comparable cell cycle data with the control membrane. Zinc oxides containing concentrations of lead are beneficial to cell cycle life. The presence of iron is detrimental to cell cycle life. The particular portion of the molecular structure of the surfactant used that is contributing to increased cycle life of cells appears to be the polyethylene oxide chain, based on the fact that carbowaxes also improve cycle life. Attempts were made to characterize pore size of materials using the electron microscope and surface replication techniques. Studies on the effect on cycle life of stoichiometric ratios of formed zinc oxide to silver are underway and are partially reported. Work on the development of a method for zinc plate surface area measurement based on comparison of high rate discharges on sheet zinc and porous zinc electrodes leads to a 1:10 area ratio.
