When the battery discharges, it uses oxygen from the air to convert metallic iron to iron oxide or rust. During the charging process, iron oxide is converted back to iron, and oxygen is given out.

Near the end of 2018, they settled on an iron-air battery, which releases energy by reacting iron with oxygen in a process similar to rusting. The firm says its battery can supply electricity for ...
