REDOX-FLOW BATTERY Redox-flow batteries are efficient and have a longer service life than conventional batteries. As the energy is stored in external tanks, the battery capacity can be scaled independently of the rated battery power. Redox-flow batteries are electrochemical energy storage devices based on a liquid storage medium. Energy conversion is carried out in electrochemical cells similar to fuel cells. Most redox-flow batteries have an energy density comparable to that of lead-acid batteries, but a significantly longer lifespan. In the electrochemical cell, electrolyte solutions flow through the half-cell compartments of the plus and minus pole. To prevent the two solutions from mixing, the half-cells are sepa- rated by an ion-conducting or semi-permeable membrane. The potential difference of the electrolytes generates a voltage at the electrodes. If the electric circuit is closed, an electrochemi- cal reaction sets in and electricity begins to flow (compare fig. 1). In order to charge the electrolytes, an external voltage is applied to the cell, and the reaction in the half-cells is initiated in the opposite direction. This reaction charges the electrolyte. As in fuel cells, individual cells can be combined in series to create a so-called “cell stack“. The stacks themselves are then connected fluidically and electrically to batteries. As redox-flow batteries are based on external energy storage media, the power and capacity of the battery can be scaled independently: the volume of electrolyte determines the battery capacity (the “quantity“ of energy stored), while the surface area and number of cells determines the power. The storage of electrolyte in separate tanks means that virtually no self-discharge occurs when the system is not in operation. This makes the technology suitable for application in uninterrupted power supply. A further field of application is the storage of energy from renewable sources, such as solar and wind.
