OverviewHistoryDesignEvaluationTraditional flow batteriesHybridOrganicOther types

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.

How does the degradation of electrolytes in flow

As electrolytes degrade, the flow battery''s capacity fades. This degradation translates into lower efficiency during charge and discharge
