Redox flow batteries are electrochemical energy storage devices. Redox flow is short for:

Reduction = electrons are bound
Oxidation = electrons are released
Flow = liquid storage medium 

And this is how it works:

1. Two tanks hold a saline solution, each containing different organic (metal-free) storage materials which function as the anode and cathode.
2. Charging and discharging is achieved by pumping the saline solution through a cell.
3. Through this process, electrons are bound and released – electricity is stored.

The result: The battery’s power and capacity can be scaled independently of one another. The amount of electrolyte determines the capacity of the flow battery, while the surface area and number of the cells determine its power.

Companies around the globe are creating new and improved battery solutions.

Most of them are currently focused on lithium-ion technology in electric mobility. Redox flow batteries are a flexible, stationary alternative to lithium-ion batteries – durable and easily scaled up to megawatt storage.

Redox flow batteries are being developed by various consortia in Europe, Asia and the Americas. JenaBatteries is a pioneer in the field.

By not using metals in the storage material, the redox flow battery from JenaBatteries is safer and more sustainable than the conventional metal-containing redox flow battery. The metal-free, low-maintenance redox flow battery from JenaBatteries is perfect for applications with high technical safety requirements. Thanks to its innovative raw material base and low price volatility, it promises planning security for modern energy infrastructures.
