The cell of a flow battery uses two chemical solutions containing ions, one acting as the anolyte (adjacent to the anode), the other as the catholyte (near the cathode). Typical redox flow batteries use ions based on iron chromium or vanadium chemistries; the latter takes advantage of vanadium’s four distinct ionic states.

If it’s manufactured on a ‘dirty’ power grid it becomes a major source of emissions over the EV lifecycle. The New Zealand Power Grid. 40% of our energy comes from renewable sources, such as hydro, geothermal and wind. For this reason, the location where the EV’s battery is manufactured is significant.
