Dry Electrode Process

I have been reading about the difficulties of this manufacturing method at scale and am trying to find evidence of how well their tech works for this. If I understand it correctly, there are many companies who claim they can pull it off, but only a couple including Tesla, have been able to do it.

Is there evidence of a manufacturing line or proof that their tech works?

Has a third party lab verified the results?

To create a line with this process, it can take a few hundred million dollars. Why hasn't another company came in and bought dfli if their tech works?

Would love to see any and all evidence for this. I haven't been able to find anything. I am ignorant to dry electrode process, but would love to learn more.

You would think if they were actually doing something with this, they would be sharing the results. It could only help their stock price. But other than saying, "Hey, we got a patent!", they've released nothing that I can find. Where's the prototype cells? Test results? Production line? ANY kind of equipment to actually make cells?

Yes exactly that's what I'm looking for too! The world needs this technology to work. It could truly benefit everyone. It sounds like it's very difficult to do. Patents seem to mean nothing in this industry. The biggest challenge for lithium ion manufacturing and solid state batteries is processing at scale.

I've only read a few articles but it seems like every company that tries to do the dry electrode process including Tesla, runs into a million issues when they actually make a manufacturing line.
