RECHARGEABLE METAL-AIR CELL.
Abstract
Experimental work was carried out to evaluate the lead-air, the cadmium-air, and the zinc-air secondary battery systems. In the lead-air battery, platinum could not be used at the cathode since its migration to the lead electrode causes severe gassing results from this. Redox cathodes have been investigated and Ferroin materials appear best. Zinc electrode utilizations of greater than 70% have resulted; however, relatively high self-discharge rates are encountered. The two-phase zinc electrodes that have been used in this work appear to be capable of sustaining higher rates than the cathodes that have been tested to date. Cycle lives of 65 cycles represent the best to date. Cadmium-air cells have shown good cycle life (greater than 100 cycles in the best case). The electrode technology for cadmium electrodes is in place. Preliminary cell design studies are underway, as it appears that cadmium-air cell systems are those most likely to be developed into hardware earliest. A number of cathodes were screened. (Author)
