the tech never existed, didn't stop them from playing it. probably a few layers of con men. oh the tech will be here any day now, we just need one teeny little step (inventing it) and it's finished! con man 2 spins it, hands off to 3, who embellishes more, each getting their little cut of the grifter cupcake until the rat turds fall out and someone realizes hey, those ain't chocolate chips!!
Supercaps kind of went thru the same schtick as they evolved. these amazing devices that could do 100k's of cycles, bla bla woof, then like an elon musk wall battery, slowly and silently the specs halve in the middle of the night and nobody was supposed to notice. now are good for 10 maybe 20 k and are fairly current limited. now they have so called hybrid supercaps or are calling them lithium supercaps, basically they glued a battery onto a capacitor and are pretending its some new marvelous tech.
believe half of what you hear, less of what you see, especially with ai now. it will keep you from looking like a fool and/or getting scammed when you double and triple down on something that just isn't true.
whats funny is, sodium batteries are making the rounds again, and they are trying to pretend they are the next disruptor, when they have been around quite a while, and have plenty of problems, and simply won't work the way lith's currently do.
whats even more funny is... terms like solid state, they can't even make up their minds what that really even means, what you must have to qualify. is it genuine or Genuine ?
