Just like the periodic news about a new study on a method that makes batteries last effectively forever, this is unlikely to be implemented.

the problem is rather to automate this and upscale this and I'm not sure how safe this method is. generally speaking if the EU makes battery recycling mandatory it definitely would benefit from a method where you don't have to grind the battery. I see this more as a PoC which can be further explored

This isn't really a viable technology because it requires careful invasive chemical injection into risky cell chemistries. Generally, liquid electrolyte and plastic separator NMC, LFP, and LiPo should be banned for all but hobby uses when far safer solid state cells with ceramic separators exist such as those offered by ProLogium. NMC are extremely dangerous under deflagration, and LFP create huge amounts of colorless and odorless hydrogen gas that has already blown up many improperly engineered buildings that used them and assumed they were "safe". Real solid state electrolyte chemistries tend to have much slower passivation growth than liquid chemistries.
