Flow Battery Research Collective

@bipolaron @kirk This project in Switzerland is currently building a 2.1 GWh capacity / 1.2 GW output redox-flow battery. Scheduled to go online in 2029, and by their own PR material "the largest in the world". https://www.swissinfo.ch/eng/climate-solutions/switzerland-builds-worlds-most-powerful-redox-flow-battery/91181119

Edit: after original post, realized that one connection lead was loose, and the negative pump tubing was blocked/degraded---PTFE liner had detached from the wall and formed some sort of blob inside the tubing, it seems.

@idlestate also, some studies of these systems I think point to complexes being formed in solution, that contain both chloride and iodide/iodine, like ICl-, for example. They might show up with some spectroscopic techniques like Raman? So chloride can play more of a role than just supporting electrolyte.

@Methylzero "I heard you like batteries, so I got you a battery for your battery..." Definitely it's backing up a headless Raspberry Pi, a potentiostat, Arduino, and two peristaltic pumps.

I mean stable as in, it hasn't obviously degraded. "Stable" cycling means different things to different people ofc.

@trevorflowers thanks for the kind words, and please feel free to ask questions about things you don't understand! I'm writing these lab notebook entries in a concise way and not doing much explaining
