The comment is satire. You get reports about amazing batteries about every month, yet ~~most~~ pretty much all of them never went into production. It has been like that for years, since I was a teenager at the very least. And what has happened since then was pretty much refinements to Li-Ion and the commercialization LiFePO.
The timeline from research to "in my products" feels like a decade.
It usually is at least a decade. New modern technology and manufacturing processes take years to decades to get up to speed because of all the hiccups and surprises they find along the way.
