Why I don't rely on Bismuth to fix my Battery problems
In my previous posts I have written a lot about the trident of problems with Iron-Chromium Redox Flow Battery, which are - Hydrogen Evolution Reaction Slow Chromium Kinetics High operating temperature for the battery Now if you ask an AI (Gemini in my case), one of the first answers it will give would be Bismuth as master solution to all 3. It stops Hydrogen evolution and makes chromium react faster, hence solving all the problems of the battery. It does that by acting as a catalyst. It forces the Cr3+ to accept electron quickly and react faster, and it has a more positive electrode potential (+0.32 V), as compared to chromium (-0.41 V), this stops water from splitting into hydrogen. Source But first you need to understand how Bismuth is incorporated in the battery - The Mechanisms- In order to use bismuth or any other catalyst in a flow battery, you have 2 choices - Electrodeposition- Dissolve bismuth chloride in the liquid electrolyte and when you apply voltage...
