In the IEEE consortium, there are much smarter people than me to know what standards apply and why they apply. But puncture testing is more important than water testing. Short answer is, the housing that seals the lithium is more important than the lithium itself.

When a Design Failure Mode and Effect Analysis(DFMEA) is done it is to make sure that it meets the FMEA under the consumers control, in its intended use. With that being said, how many layers will the battery housing carry to protect the lithium? And for lithium to be exposed, those layers need to be shredded apart. H2O, and lots of O, are needed in order for rapid thermal transformation(fire).

Then liquid Lithium compared to solid lithium, there are so many things that can go wrong in liquid. Solid we really don’t know if it will have the same factors of failure. Just because it isn’t liquid, SSB could run into a whole slew of problems not even considered.

As for the video, I think you showed me this once already and I played it in the background while working. This time I watched it and enjoyed it more this time. Jahn Teller Effect, if you can understand what that means you are headed down the right path of making the perfect battery.

Hope this helps,
