@curiouscarbon - you hit the nail on the head.
There is no way to determine the SEI layer condition with cells of unknown past history. And if in fact they claim to be new, that they are not counterfeit. One can get counterfeit A123 wrappers to go over / replace old ones pretty easily. Or the more common one of sitting in a hot warehouse for a few years, and then zapped just a little bit before sending them out.
Even vapers get ripped off at times.
To be sure, marketers targeting us who may read these threads, will now supply either bogus x-ray imaging photos!
Ironically, an additional profit can be made by selling all the paraphenalia that goes with it. Tack welders, nickel strips, soldering guns - and now x-ray machines (why didn't I think of that!), special holders. That's some good $$$ to be made. Get a buddy to make some videos with links to our "product".
The problem of supporting band-aids (no matter how scientifically well it is discussed) over the initial problem of trash, is that we are sending mixed messages to manufacturers that it is ok to do so - despite us trying to hold them accountable to the highest standards of quality in other battery systems.
