Title:
FLOW BATTERIES WITH MODULAR ARRANGEMENTS OF CELLS
Document Type and Number:
WIPO Patent Application WO/2014/145692
Kind Code:
A3
Abstract:
A modular arrangement of cells that enables adjustments in cell currents in response to changes in concentration of the redox reactants. The adjustments improve battery efficiency by more closely matching the current in a given cell to the rate at which reactants are supplied to that cell. The cell modules provide the flexibility to operate flow batteries efficiently over a wide range of electrolyte states of charge and allow managed scale-up while easing manufacturability concerns.
