#RealTimeChem cycling an all-iron flow battery!!
First few "cycles" are oxidizing sacrificial excess ascorbic acid added to reduce initial Fe (III) present and minimize ambient oxygen. Charged 2 mAh and discharged until discharge capacity approached 2 mAh as ascorbic acid was oxidized. Now going to higher capacities

I'm no chemist, so this may not apply here, but I've been looking at info on different batteries. I looked at Nickel/Iron because of their known long life. One change mention from original Edison design is adding a little Lithium oxide or dioxide ( forget exactly) to the electrolyte To extend the life of the Iron electrode.
There was also something about making plates (instead of just using sheets of iron) using iron powder with carbon (for conductivity) and something else which I forget that reduced the production of hydrogen.
