The battery type that you will explore in this science project is called a metal air battery or, more specifically, a zinc-air battery, sometimes also referred to as a saltwater battery. The zinc-air battery is a relatively mature technology and is most commonly used in hearing aids and watches due to its high energy density.
The result is an aluminum-air prototype with a much longer shelf life than that of conventional aluminum-air batteries. The researchers showed that when the battery was repeatedly used and then put on standby for one to two days, the MIT design lasted 24 days, while the conventional design lasted for only three.
The Zn-air battery is stereotypically composed of 4 main components (a) an air electrode containing a catalyst-painted gas-diffused layer (GDL) (b) an alkaline electrolyte (c) a separator, and a Zn electrode (anode). During the discharge process, the Zn-air battery works as a power generator via an electrochemical reaction of the Zn …
