In 1974, scientist L.H. Thaller introduced a groundbreaking electrochemical energy storage technology—the redox flow battery (RFB). Unlike conventional batteries, the greatest innovation of flow batteries lies in storing positive and negative electrolytes in external tanks, which are circulated into the cell stack during operation. This unique design provides greater flexibility, scalability, and safety. Among them, aqueous organic flow batteries stand out for their high safety and environmental friendliness, making them a key solution in modern energy storage.

Working Principle

Flow batteries store and release energy through reversible redox reactions between two electrolytes that are continuously circulated on either side of an ion-exchange membrane. With water as the solvent, aqueous systems offer superior safety and sustainability, making them highly attractive for renewable energy storage.

In research and development, laboratory pumps play a vital role by supporting:

• Electrolyte Circulation – Ensuring stable transfer of electrolytes between cell tanks.

• Solution Mixing – Combining electrolytes of varying concentrations or compositions for consistent performance.

• Oxidant/Reductant Delivery – Precisely feeding redox agents to drive efficient energy storage and release.
