Polarization tests have been obtained for the nickel fluoride cathode. These data indicate a high degree of polarization on both charge and discharge. Improvements in both the polarization and utilization of the nickel chloride cathode have been achieved. Electrochemical formation greatly improves utilization. The lithium anode has been found to be satisfactory and is not a limiting factor at present. Examination of a laboratory cell after cycling is discussed. A precipitate formed in the electrolyte on cycling has been found to be 2 aluminum and 35 chlorine. This combination does not bear out the hypothesis of a hydrolized aluminum chloride since the ratio of chlorine to aluminum is too great. A project review was conducted by the research staff. Based on the data available from compatability tests and electrochemical tests, a hypothetical cell has been designed. Author
