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.
Based on the electro-active materials used in the system, the more successful pair of electrodes are liquid/gas-metal and liquid-liquid electrode systems. The commercialized flow battery system Zn/Br falls under the liquid/gas-metal electrode pair category whereas All-Vanadium Redox Flow Battery (VRFB) contains liquid-liquid electrodes.
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.

Other true flow batteries might have a gas species (e.g., hydrogen, chlorine) and liquid species (e.g., bromine). Rechargeable fuel cells like H2-Br2 and H2-Cl2 could be thought of as true flow batteries. Systems in which one or more electro-active components are stored internally are called hybrid flow batteries.
Li-Ion Batteries (LIBs) and Redox Flow Batteries (RFBs) are popular battery system in electrical energy storage technology.
