The basic D cell made on this contract has the same construction as that developed on previous contracts except for an improved carbon cup which utilizes a thermosetting resin binder instead of the coal tar pitch formerly used. Thirteen experimental lots were made and put on test to evaluate various materials for the cell jacket, the anode sealing washer and the insulating and reinforcing tape. No definite differences in performance were observed between cells using different materials of construction, except that polyvinyl tape was found to deteriorate at 160F and allow cells to dry out. Nine experimental lots having electrolytes of mixed magnesium and strontium bromides in three molecular ratios and in three normalities, together with magnesium bromide controls, were made to investigate the effects of mixed bromide electrolytes on low temperature performance and delay time. Capacity maintenance at 130F was over 90 per cent at up to five months. Uniformity was good. The feasibility of making a C cell was demonstrated and tools were made to make parts for this size cell using the same design and materials of construction as are used in the D cell. Author
