Flow battery manufacturers offer a variety of chemistries including vanadium, iron chromium, zinc bromine, zinc iron and more. Flow batteries can also be redox, hybrid and membraneless. Redox flow batteries employ reduction (a gain of electrons) and oxidation (a loss of electrons) reactions as electrons are transferred in the electrolyte.

Flow batteries are particularly attractive for their ability to decouple energy and power. The specific choice of catholyte and anolyte chemistry will dictate the voltage of an individual cell and the energy density of the system. Therefore, the overall energy of a flow battery may be controlled by varying the volume of electrolyte.

The most common flow battery type is the redox flow battery, or also called: true redox flow battery. As already explained, the energy is stored as positive and negative electrolytes in separate tanks outside of the core. The electrodes of the core are separated by a membrane and each electrolyte flows within the positive and negative circuits ...
