I started following battery tech at the turn of the century and this was old behavior even then.

Battery prototypes are the moral equivalent of announcing you've found a new chemical that kills tumors - in vitro.

Back then the advice from others watching battery technology? If their tech is 10 years ahead of the current state of the art, then either it will take them 10 years to produce it or they will produce it sooner by sacrificing capacity for safety/manufacturing concerns.

Another important thing to remember in any discussion about power - there is almost always a substantial premium paid for portability. If someone is feeding you PR about a stationary power system and comparing it to any household-name portable system, then you should smile and nod and keep track of your wallet as you back away slowly. They are the snake in the grass your ancestors warned you about.

Why would anyone care at all about portability for grid storage? This makes no sense.

Why would anyone favor lithium ion for grid storage? Makes no sense. So if someone is comparing their product to something that makes no sense, they aren’t making sense.

Are they confused, or just lying?

I would pretty much agree except that lithium ion keeps being sold as a grid storage solution for some reason. But yes they should obviously be showing superiority to lead acid, pumped hydro, etc. as well.
