Flow battery design can be further classified into full flow, semi-flow, and membraneless. The fundamental difference between conventional and flow batteries is that energy is stored in the electrode material in conventional batteries, while in flow batteries it is stored in the electrolyte. A flow battery may be used like a fuel cell (where new charged negolyte (a.k.a. reducer or fuel)
Flow batteries are named after the liquid electrolyte flowing through the battery system, each category utilizing a different mechanism. A ''true'' RFB uses a liquid phase reduction–oxidation reaction and the total electricity generation capacity depends on the storage tank size. In contrast, hybrid RFBs have a liquid–solid transition and store at least some

The study, published in the journal Joule, reveals that the flow battery maintained its capacity for energy storage and release for over a year of constant cycling. A common food and medicine additive has shown it can boost the capacity and longevity of a next-generation flow battery design in a record-setting experiment.
Flow batteries differ from solid-state batteries in that they have two external supply tanks of liquid constantly circulating through them to supply the electrolyte, which is like the “blood supply” for the system. The larger the electrolyte supply tank, the more energy the flow battery can store.
Flow batteries have the potential for long lifetimes and low costs in part due to their unusual design. In the everyday batteries used in phones and electric vehicles, the materials that store the electric charge are solid coatings on the electrodes.
Now, MIT researchers have demonstrated a modeling framework that can help. Their work focuses on the flow battery, an electrochemical cell that looks promising for the job—except for one problem: Current flow batteries rely on vanadium, an energy-storage material that’s expensive and not always readily available.
