Other flow-type batteries include the zinc–cerium battery, the zinc–bromine battery, and the hydrogen–bromine battery. A membraneless battery relies on laminar flow in which two liquids are pumped through a channel, where they undergo electrochemical reactions to store or release energy. The solutions pass in parallel, with little mixing.
The most widely commercialized flow battery technology is based on vanadium redox chemistry. Both tanks contain vanadium ions but in different oxidation states, allowing the same element to be used for both sides of the battery. This simplifies electrolyte management and recycling.
Flow batteries can be classified using different schemes: 1) Full-flow (where all reagents are in fluid phases: gases, liquids, or liquid solutions), such as vanadium redox flow battery vs semi-flow, where one or more electroactive phases are solid, such as zinc-bromine battery. 2) Type of reagents: inorganic vs. organic and organic forms.
