METAL-AIR CELLS.
Abstract
Information is presented on primary magnesium-air and secondary cadmium-air, zinc-air and iron-air systems. Performance data and problems in cell design are reviewed. Estimates of energy densities for the four systems range from 40 to 80 Wh/lb. Modifications of anode make-up and electrolyte composition have improved capacity and cycle life. The use of platinum air cathodes in rechargeable (secondary) metal-air cells avoids the decrease in energy density that otherwise would occur if non-noble metal air cathodes, in combination with auxiliary charging electrodes, were used. Electrode-electrolyte balance, active anode material utilization, water balance, dendrite formation, carbon dioxide contamination, etc. are among the areas which have been studied and which require further investigation.
