AN058 – Redox Flow Battery. Implementation of bidirectional DC/DC converters

A Flow Battery is a type of rechargeable fuel cell where one or more dissolved electroactive elements flow through a cell to convert chemical energy into electricity.

The electrochemical elements that act as the anolyte and catholyte do not have physical contact between each other and produce electricity through a REDOX (reductionoxidation) process. In this process ions are transferred through the membrane in the cell to drive the anolyte and catholyte into other reduction/oxidation states.

The economic effectiveness of the flow battery stems from the clear advantage it holds in terms of cost-efficiency. The separation between energy and power characteristics plays a pivotal role in making the flow battery highly favorable for high-energy, low-power applications. This is primarily due to the simplicity and affordability of expanding the volume of electrolyte, which enables the flow battery to deliver significant energy capacity without incurring substantial costs.
