Zinc–air hearing aid batteries PR70 from both sides. Left side: Anode and gasket. Right side: Cathode and inlet opening for the atmospheric oxygen. A zinc–air battery is a metal–air electrochemical cell powered by the oxidation of zinc with oxygen from the air.

A metal–air electrochemical cell is an electrochemical cell that uses an anode made from pure metal and an external cathode of ambient air, typically with an aqueous or aprotic electrolyte. [1] [2] During discharging of a metal–air electrochemical cell, a reduction reaction occurs in the ambient air cathode while the metal anode is oxidized.
Energizer hasn't exactly been keeping this one much of a secret, but the battery maker has now finally gotten official with its much-vaunted Zinc Air Prismatic battery technology, which it says ...
The use of low cost and abundant metals, such as zinc, at the anode and the absence of hermetic packaging means that the cost of metal–air batteries can be very low. Issues related to dendrite formation at the anode and the absence of a long-life bifunctional (charge and discharge) air cathode have limited the cycle life of zinc–air systems.
A 1919 illustration of a Leclanché cell. The Leclanché cell is a battery invented and patented by the French scientist Georges Leclanché in 1866. [1] [2] [3] The battery contained a conducting solution (electrolyte) of ammonium chloride, a cathode (positive terminal) of carbon, a depolarizer of manganese dioxide (oxidizer), and an anode (negative terminal) of zinc (reductant).
Zinc, in particular, is widely recognized as a beneficial alloying element in Al-air battery anodes because it helps reduce the self-corrosion rate and increases the nominal cell voltage. However, study done by Park, Choi, and Kim highlights a drawback: the addition of Zn can actually decrease the discharge performance of the anode in alkaline ...
A zinc-ion battery or Zn-ion battery (abbreviated as ZIB) uses zinc ions (Zn 2+) as the charge carriers. [1] Specifically, ZIBs utilize Zn metal as the anode , Zn-intercalating materials as the cathode , and a Zn-containing electrolyte .
