Does a cathode affect the energy density of a zinc air battery?

Thus, the cathode in zinc–air batteries is not affected by a material limitation and since the cathode active material is in a gaseous state, it does not contribute to the increase of the total mass but on the other hand increases the energy density of the whole battery.

What affects the power density of Zn-air batteries?

However, battery power density is affected by cell configuration or structure, in addition to the type of zinc used and the catalyst on the air electrode. The power density of Zn-air batteries can be increased from 135 to 170 mW cm −2 by reducing the distance between the anode and cathode from 2.5 to 1 cm [ 28 ].
