That guy on Undecided is a bit of a dunce. He never actually checked or tested in any way that the yoshino psu uses real solid state batteries. He just bought it from Amazon and it’s advertised on Amazon as having them.
But they likely aren’t solid state batteries in that psu he bought. He even admitted as much in a podcast just last week.
Other people have done teardowns on those yoshino batteries and have apparently found that they are not solid state. They still contain a liquid.

So we’re still in a limbo period with nothing actually on the market.
