Oxygen consumption of zinc-air batteries and their performance at low oxygen concentration levels

Already existing primary Zinc-air batteries provide a high energy density. Due to new secondary cells, its technology can become an alternative for energy storage. Since these applications require a big amount of storable energy, the oxygen consumption has to be taken into account. This article determines the oxygen consumption of zinc-air batteries during discharging. Furthermore the performance of zinc-air batteries at low oxygen concentrations is analyzed. Both aspects are validated by practical experiments.
