HIGH RATE PRIMARY ZINC/AIR BATTERY.
Abstract
The materials and processing costs of the cathode for the high rate primary battery were investigated to achieve an effective cost reduction while still maintaining performance and reliability. Concurrent with this investigation, development of both paste and pressed powder anodes centered on the uses of New Jersey powder no. 1222. It was determined that this zinc powder, when combined with inert fillers, was more desirable than reduced zinc oxide/dendritic zinc powder combinations from the standpoint of handling, processing and cost considerations. Work was carried out on the optimization of techniques used in the fabrication of anodes and the investigation of various inert filler materials. Laboratory results have shown that either the pressed or paste anodes can meet the capacity requirements specified for this program. The final choice of anode type will depend on: (1) capacity achieved in multicell testing; (2) ability to be stored at high temperatures; (3) adaptability to automated production and (4) to a bicell design that can be automatically assembled. An improved test cell to be used for anode and cathode evaluation was designed and fabricated. (Author)
