The cathode in a zinc-air battery is atmospheric oxygen molecules.
Zinc-air batteries are a type of battery that uses a chemical reaction between zinc and oxygen from the air to generate electricity. Key components of a zinc-air battery include:
- Zinc powder anodes
- Catalytic cathodes
- Alkaline electrolyte
The unique feature of zinc-air batteries is that they use atmospheric oxygen molecules as the active cathode material. This design allows zinc-air batteries to store twice as much energy as primary batteries, although a cell can be quite large and take up a significant amount of space.
