A scientific breakthrough can happen and is news worthy. The consequence might be mass production of some thing enabled through decade of R&D that follows the breakthrough. But there are lots of reasons why that might never happen.

Anyway, catchy click bait news lines sell. And breakthroughs are worth reporting on by themselves. Anyway, the economist didn't do a great job here doing their job. They are all over the place mixing things that are basically on the market (sodium ion) or nearly on the market (solid state) with various scientific progress from research labs.

As for the rest of your comment, I don't think accurate information is your problem.
