All Iron Battery

It contains two chemical reagents one of which is oxidized and the other is reduced.

All iron battery.

I ran the numbers. An aqueous all iron redox flow rechargeable battery with a nominal cell voltage of 1 21 v and theoretical specific energy of 170 wh kg is a promising low cost durable and eco friendly energy storage system for large scale applications. If the world used all of its lead lithium or iron to build a battery lead and lithium would be small as a percentage of the grid. Iron looks pretty good.

An all iron redox flow battery is proposed and developed for end users without access to an electricity grid. New all iron redox flow battery for renewables storage scientists in the u s. The all iron cell is similar to historical electrochemical cells like the edison cell iron nickel first. Several companies and universities are conducting research and developing their own iron flow battery.

The concept is a low cost battery which the user assembles discharges and then disposes of the active materials. Iron is a very cheap material and iron chemistry doesn t require special handling for air sensitivity or toxicity. We could make a grid scale iron battery without. The result is current flow through a connected electrical load.

The company s all iron batteries housed and sold in a solution called energy warehouse are intended to offer long durations of energy storage beyond the limits of around 2 4 hours typically seen in grid or commercial scale lithium battery storage. 1 minimize upfront cost 2 maximize discharge energy and 3 utilize non toxic and. The design goals are. According to the department of energy s arpa e division flow batteries store chemical energy in.

The all iron battery is an electrochemical cell for powering an electronic device.
