Problem Statement

  • Redox flow battery systems store energy in electrolyte solutions (a positive solution & a negative solutions) which flowed through respective electrode compartments of the cells of a multi-cell electrochemical reactor during charge & discharge process.
  • Conventional vanadium redox flow battery systems use vanadium ions (100%) for gigawatts(GW) energy storage applications. However said vanadium is one of scarce material, wherein 88% of total vanadium (15MMT) available in earth are from China, Russia, & Australia.
  • Hence, there is a need exists for alternatives like organic compound, which are ubiquitous across the globe, which may be addressed the solutions of above shortcomings in term of economic significant point of view also.

Technology

  • Present invention describes an organic catholyte material for aqueous organic flow battery (Redox Flow Battery (RFB)).
  • The organic flow battery comprises at least one high voltage organic redox material.
  • The high voltage ubiquitous organic redox material series are stable, soluble and reversible in RFB applications.

Key Features/Value Proposition

Technical Perspective:

  • The invention proposes use of Dopamine & its simple derivatives envisaged for exploration as catholyte.
  • If used in vanadium redox flow battery, could reduce vanadium need by 50%.

Industrial Perspective:

  • A cost effective and safe aqueous based energy system
