A flow battery, or redox flow battery (after reduction–oxidation), is a type of electrochemical cell where chemical energy is provided by two chemical components dissolved in liquids that are pumped through the system on separate sides of a membrane. Ion transfer inside the cell (accompanied by current flow through an external circuit) occurs across the membrane while the liquids circulate in their respective spaces.
Flow Battery Energy Storage – Guidelines for Safe and Effective Use (the Guide) has been developed through collaboration with a broad range of independent stakeholders from across
