Limiting Factors for Zinc-Air Batteries at Low and Elevated Temperatures.
Abstract
Zinc-air batteries offer significant advantages over conventional primary and secondary batteries in terms of weight, power capability, and mechanical recharge for manpack electronic equipment. However, serious problems exist in maintaining the inherently high energy density under intermittent discharge conditions at both low temperatures (below 32F) and elevated temperatures (up to 160F). The report covers an investigation of factors influencing and/or limiting the performance of mechanically rechargeable zinc-air cells under these conditions and makes recommendations for design and operation to extend the performance capability. While it is true that the tests reported were conducted on mechanically rechargeable zinc-air cells, most of the conclusions and recommendations can be applied to the primary water activated zinc-air cell as well.
