Using iron to storing energy

Will Iron-Air Batteries Revolutionize Renewable Energy Storage?

During discharge, iron reacts with oxygen from the air to form rust (iron oxide), releasing energy. When recharged, electricity from an external source reverses this reaction, converting the rust into iron and releasing oxygen into the air. This cycle makes iron-air batteries an efficient option for storing and releasing energy, particularly
