Iron-chromium flow battery for renewables storage Researchers in China have successfully prepared cobalt oxide-modified graphite felt as an electrode material for an iron-chromium flow battery.

Iron-chromium redox flow batteries are pivotal in addressing the challenges of renewable energy sources, such as solar and wind, which often suffer from inconsistency in energy supply.

A new iron-based aqueous flow battery shows promise for grid energy storage applications.
