Abstract
A method for storing and releasing power using a metal-air battery, which includes: (a) a discharge phase during which a first positive air electrode is connected to the positive terminal of the battery and a second positive oxygen-release electrode is disconnected from the positive terminal of the battery; (b) a recharging phase during which the second positive oxygen-release electrode is connected to the positive terminal of the battery and the first positive air electrode is disconnected from the positive terminal of the battery, and during which the potential of the negative electrode is measured relative to the first positive air electrode. Also disclosed is a metal-air battery designed especially for implementing said method.
