The high energy density of Zinc Air is made possible by using a thin air electrode where the cathode reaction takes place and by using atmospheric oxygen as the cathode reactant. The result is greater internal volume for zinc, the active anode material. More zinc translates into longer runtime in similar overall volume. Figure 3 demonstrates the higher energy density of Zinc Air compared to other consumer battery systems. The chart on the left displays volumetric energy density in units of Wh/L, and the chart on the right shows gravimetric energy density in units of Wh/kg. This data is based on the volume of a AA sized battery for all systems and a continuous 50mA current drain to a 0.9 volt cutoff.

Energizer Zinc Air Prismatic batteries have an operating voltage similar to Alkaline, which is between

1.10and 1.30 volts depending on the drain rate of the device. The discharge profile however is relatively flat similar to rechargeable Nickel Metal Hydride batteries. Figure 4 contains examples of discharge curves for Zinc Air, Alkaline, Nickel Metal Hydride, and Lithium Iron Disulfide batteries. Even though the Zinc Air PP355 battery has the same external volume as the AAAA battery, it delivers up to 3X the runtime at a 50 mW discharge.
