Redox-flow batteries, based on their particular ability to decouple power and energy, stand as prime candidates for cost-effective stationary storage, particularly in the case of long discharges and long storage times.
A typical flow battery consists of two tanks of liquids which are pumped past a membrane held between two electrodes.

Aqueous redox flow batteries typically offer the promising characteristics of high safety, high power density, and economic sustainability, but the limited energy density and cycling stability remain as key challenges.
Generally, the redox species is dissolved in the electrolyte and stored in two tanks respectively, which are circulated through a peristaltic pump. Unlike other batteries, this design allows for the separation of electrochemical reaction sites (electrodes) and the storage of active materials in space.
