Organic redox flow batteries can be a suitable alternative to the dominant lithium-ion battery storage systems. Organic redox flow batteries have three advantages over lithium-ion batteries. These advantages are its cost-effectiveness, safety, and completely recyclable.
As one of the hot topics in the battery storage sector, recycling and recyclable materials have gained momentum recently. Using recyclable materials in different technologies of this sector is one of the main pillars of the circular economy.
A circular economy is an alternative to a traditional linear economy (make, use, dispose of material). In the circular economy resources of materials are kept in use for as long as possible, extract the maximum value from them whilst in use, then recycling products and materials at the end of each service life.
The safety of organic redox flow batteries stems from using water as an electrolyte ias opposed to lithium-ion batteries. But the drawback of water-based redox flow batteries is its low energy density.
This low energy density is marginally compensated by using organic electrodes in the organic redox flow battery. This type of redox flow batteries with a large capacity can be used to store energy from wind turbines and solar panels, and as a power bank for cars.
It is important to note that typical redox flow batteries often contain vanadium, a scarce and expensive metal. It is the main driver of less popularity of this type of redox flow batteries.
