     <h1>Flow Batteries</h1>
     <p>Flow Batteries, or Vanadium Redox Flow Batteries, are a type of electrochemical cell where energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane. They provided a longer cycle life than typical Lithium-Ion batteries used widely today, they are safe to dispose off, and the technology is relatively easy to set up and manufacture.</p>
