Flow Battery Research Collective

@kirk In general this is exactly the way how all of us should act here (and in all other open source projects). But it is always better to have something like this in advance and it does not harm. I highly welcome to have a written code of conduct. Thanks Kirk, for taking care.

Here is a video of assembling the large-format cell. https://spectra.video/w/m9RKg1QWrFdkkn9qUBFMTS FYI, you are meant two use two endplates per side (I used one here), I intentionally left the graphite felt out as this was for leak-testing, and the cell is missing washers on one side. The video illustrates the basic process of assembling our cell and how it is designed and seals. All the design files are available at https://codeberg.org/FBRC/RFB-large-format-cell. The setup is essentially there, waiting on chemicals and sorting out the power electronics set up and we should be able to run our first real charge/discharge tests with this large-format cell! The work to get to this point has been supported by the NGI0 Entrust Fund, a fund established by NLnet, to whom we are very grateful!

Charging to 6Ah/L at 30mA/cm2 and discharging at 5mA/cm2. At most we only get 2-3 Ah/L of available capacity, same as if we charged to 4Ah/L. [image: 1758211363268-f3e1b8fc-98a1-4c8b-b305-b4d4a5bedee6-image.png]
