Abstract:

Work toward producing the first complete subject, author and facility index for the first 970 documents in the Battery Information Index is described. It is to be produced by Flexowriter and a copy will be stored on punched tape, ready for any computer processing anticipated. The characteristics of using a Flexowriter or computer are briefly described. The merger of a collection of lithium battery documents into the present index is discussed. Recommendations for the selection of instrumentation for battery research, and development work and for the reporting of experimental procedures is given. As a precursor to making improved nickel-cadmium and silver-zinc cells, work has progressed toward fabricating nickel electrodes. Preliminary batches have been made. A tear-down procedure is also given for complete cells in order to characterize them both physically and chemically. This tear-down procedure, and the orbital cycling experiments under way serve as a reference point for improved designs. Presently all groups of cells have proceeded through the second eclipse season of simulated orbital life tests and changes in electrical parameters are reported. Experiments with silver-zinc cells have led to minor modifications of the original failure analysis procedure. Author
