A vanadium redox battery energy storage system is disclosed. The system may include a battery cell stack having at least one cell having a catholyte solution, a positive electrode in communication with the catholyte solution, an anolyte solution, a negative electrode in communication with the anolyte solution, and an anion exchange membrane separating the catholyte solution from the anolyte solution. Another cell in the cell stack includes a cation exchange membrane instead of an anion exchange membrane. A cell stack having a combination of cation and anion exchange membranes is configured to restrict net water shift, net vanadium transport and net change of proton and sulfate concentrations in the anolyte and catholyte solutions.
