Oh JFC, does anyone expect any of these "could" battery breakthroughs to ever go anywhere?

I honestly don't even want to hear about them. Let me know when you're shipping commercially. Until then, it's just a waste of time and an attempt to drum up research funding. That's it.

The article was about way more than what the headline promised, and I learned a good deal about the different battery options.

If you don’t like those headlines, don’t click on them? It’s that easy (and it’s your loss too.)

I had the original knee jerk reaction, but then thought better about it before making a post like this.

Think of these new battery tech write ups as a pitch from a startup looking to get funding. They will of course paint the concept in the rosiest of pictures even though there's no functioning tech yet. They need the funding to develop the concept into a viable working product. This forum is a place full of people interested in this kind of tech, so by being a reader of this forum, you'll see a lot of this kind of stuff. One day, one of these might actually work and if you see it here first and "get in on the ground floor" you might get "founder" rich too.

It's not some radical breakthrough. It's an improvement to lithium-ion, like lots of others that have in fact hit production over the past couple decades. We have half a dozen different cathode chemistries, we've improved energy density by an average of five percent per year, costs have dropped enormously. That's why electric cars are a lot more viable now than they were at the turn of the century.

I suspect you didn’t read the article. It was remarkably enlightening.

Is it so bad to drum up research funding? How else will we get to that commercial availability step?

I too am annoyed by the journalism in this space but I like reading about the science and engineering.
