Meaning and Definition
A type of battery that generates electrical energy from a chemical reaction involving oxygen from the air and a metal.
A secondary (rechargeable) or primary (non-rechargeable) electrochemical cell that uses an open cathode, typically containing zinc or lithium, which reacts with atmospheric oxygen. Also refers colloquially to any device that stores compressed air energy for mechanical power.

FAQ
Frequently Asked Questions
No, though both use oxygen. A fuel cell continuously consumes external fuel (e.g., hydrogen). An air battery has a consumable metal anode sealed inside and is typically a primary or rechargeable cell.
Yes, zinc-air batteries are commonly sold for hearing aids and some film cameras. Larger, rechargeable types for electronics or vehicles are still largely in research.
They use oxygen from air (free and abundant) as a cathode material, reducing battery weight and the use of heavy, toxic materials. Some types use zinc, which is more recyclable than other metals.
For rechargeable types (like lithium-air), the main challenges are poor cycle life due to cathode clogging, moisture sensitivity, and slow reaction rates, which limit power output.
