Is a energy storage technology.
Can be designed for high power and long storage duration.
The battery is charged and discharged by reversible chemical reaction
between the liquid electrolyte.
The development of flow battery had reached demonstration project in
India, there is no manufacturing unit.

28. Characteristics of
Flow Batteries
 High power.
 Long duration.
 The system is re-fillable, electrolytes can be replaced easily.
 Most redox reactions are very rapid (fast reaction kinetics), which
makes the reaction time very short about 1/1000 s.
 The full-cycle efficiency of the battery is relatively low (75% - 80%),
due to the energy needed to circulate the electrolyte and losses due to
chemical reactions, e.g. forming of hydrogen.
 The system does not have any self-discharge, as the electrolytes cannot
react when they are stored separately
 High power.
 Long duration.

32. Operation
 The electrolyte is prepared by dissolving vanadium pent-oxide
(V2O5) in sulphuric acid (H2SO4).
 The Negative half cells of electrolyte contains only V2+ and V3+
ions and the positive half-cell electrolyte contains only
VO2+(V4+) and VO2
+(V5+) ions.
 Both the electrolyte solution are stored separately in storage tank
and pump is used to circulate through cell.
 The reaction take place on graphite felt electrode and electrons
are transferred to other cell.
