High Quality Content by WIKIPEDIA articles! Zinc-air batteries, and zinc-air fuel cells, (mechanically-rechargeable) are electro-chemical batteries powered by oxidizing 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 film cameras that previously used mercury batteries. Zinc particles 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 (Zn(OH)2 4), releasing electrons to travel to the…mehr

High Quality Content by WIKIPEDIA articles! Zinc-air batteries, and zinc-air fuel cells, (mechanically-rechargeable) are electro-chemical batteries powered by oxidizing 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 film cameras that previously used mercury batteries. Zinc particles 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 (Zn(OH)2 4), releasing electrons to travel to the cathode. The zincate decays into zinc oxide and water is returned to the system. The water and hydroxyls from the anode are recycled at the cathode, so the water serves only as a catalyst.
