  • Zinc-air batteries (non-rechargeable), and zinc-air fuel cells, (mechanically-rechargeable) are electro-chemical batteries powered by the oxidation of zinc with oxygen from the air. These batteries have high energy densities and are relatively inexpensive to produce. They are used in hearing aids and in experimental electric vehicles. They may be an important part of a future zinc economy. Particles of zinc are mixed with an electrolyte; water and oxygen from the air react at the cathode and form hydroxyls which migrate into the zinc paste and form zincate (Zn4), at which point electrons are released and travel to the cathode. The zincate decays into zinc oxide and water is released back into the system. The water and hydroxyls from the anode are recycled at the cathode, so the water serves only as a catalyst. The reactions produce a maximum voltage level of 1.65 volts, but this is reduced to 1.4–1.35 V by reducing air flow into the cell; this is usually done for hearing aid batteries to reduce the rate of water drying out. The term zinc-air fuel cell usually refers to a zinc-air battery in which zinc fuel is replenished and zinc oxide waste is removed continuously. This is accomplished by pushing zinc electrolyte paste or pellets into an anode chamber. Waste zinc oxide is pumped into a waste tank or bladder inside the fuel tank, and fresh zinc paste or pellets are taken from the fuel tank. The zinc oxide waste is pumped out at a refuelling station and sent to a recycling plant. Alternatively, this term may refer to an electro-chemical system in which zinc is used as a co-reactant to assist the reformation of hydrocarbon fuels on an anode of a fuel cell. Zinc-air batteries have properties of fuel cells as well as batteries: the zinc is the fuel, the rate of the reaction can be controlled by controlling the air flow, and used zinc/electrolyte paste can be removed from the cell and replaced with fresh paste. Research is being conducted in powering electric vehicles with zinc-air batteries.
  • Eine Zink-Luft-Batterie ist eine Primärzelle (umgangssprachlich meist Batterie, eine elektrische Einweg-Zelle), deren Spannung von maximal 1,65 V aufgrund einer Zink-Sauerstoff-Reaktion entsteht. Meist wird die Spannung durch Reduzierung der Luftzufuhr auf 1,35 bzw. 1,4 V reduziert, um Kompatibilität zu nicht mehr hergestellten Quecksilberoxid-Zink-Batterien zu gewährleisten, wie sie beispielsweise in Hörgeräten eingesetzt werden. Die Zink-Luft-Batterie wurde vor allem aufgrund des Rohstoffmangels nach dem Zweiten Weltkrieg entwickelt. Heute bietet sie in der Bauform als Knopfzelle durch besonders hohe Energiedichte und eine annähernd waagerechte Entladungskurve die optimale Stromversorgung für analoge und digitale Hörgeräte. In der Zink-Luft-Batterie wird Zinkmetall mit Luftsauerstoff in einem alkalischen Elektrolyt zum Oxid oder Hydroxid oxidiert und die dabei freiwerdende Energie elektrochemisch genutzt. Es laufen die folgenden Reaktionen ab:

Akumulator cynkowo-powietrzny jest stosunkowo nowym typem akumulatora, będącym wciąż w fazie badań. Budowa jest zbliżona do jednorazowych ogniw cynkowo-powietrznych, stosowanych masowo jako źródło prądu w aparatach słuchowych i urządzeniach przywoławczych.
