Abstract
A Vanadium chemistry flow cell battery system is described. Methods of forming the electrolyte, a formulation for the electrolyte, and a flow system utilizing the electrolyte are disclosed. Production of electrolytes can include a combination of chemical reduction and electrochemical reduction.
Claims26
A method for providing an electrolyte solution, comprising:
- chemically reducing an acidic solution/suspension of V5+ to form a reduced solution;
- and
- electrochemically reducing the reduced solution to form an electrolyte.
A flow cell battery system, comprising
- a positive vanadium electrolyte;
- a negative vanadium electrolyte;
- a stack having a plurality of cells, each cell formed between two electrodes and having a positive cell receiving the positive vanadium electrolyte and a negative cell receiving the negative vanadium electrolyte separated by a porous membrane.
