Abstract : This report is divided into four sections. The first contains the data on electrolyte studies, particularly those to be used with nickel fluoride cathode. Conductivity, viscosity, and equivalent conductivity at infinite dilution, are given for most of the solute-solvent combinations. The second section deals with the nickel fluoride cathode. Data on porosity, pore size distribution, true surface area (by the BET method) and electrode performance are given for a variety of electrode mixes. Variations of conductive diluent, binder, and extender, as well as various types of nickel fluoride were used. The third section contains cell testing data. Automatic cycling and chronopotentiometric tests are presented. The fourth section contains the conclusions. Those are that propylene carbonate with potassium hexafluorophosphate is still the most practical electrolyte. The conductive diluent has the greatest effect on the surface areas and pore size distribution so it has the greatest electrochemical effect on the electrode. Conductex, a high conductivity carbon produced the best electrode. (Author)
