Flow batteries are electrochemical storage systems that store energy in liquid electrolytes contained within external tanks. The energy can be scaled independently by adjusting the volume of the electrolyte tanks, which allows for long-duration storage.
Flow batteries address the need for long-duration storage that can support grid-scale applications without the limitations on energy density found in solid-state battery technologies.
In a flow battery, two tanks hold different electrolyte solutions. These solutions pass through an electrochemical cell stack where they react to store and release energy. Power output is controlled by the size of the cell stack, while energy capacity is determined by the volume of electrolyte in the tanks.
Manufacturing involves creating the electrochemical cell stacks, designing and constructing the liquid electrolyte storage tanks, and integrating these components into a functional system. The process requires precision in material selection and assembly to ensure efficient operation and long lifetimes.
The build process includes component design, fabrication of cell stacks using materials like electrodes and membranes, tank construction, and integration testing to ensure the system operates as intended before deployment.
