"Another promising avenue"... fantastic. Deja Vu all over again.

I suppose it's good news but the thing that ultimately turns out to be missing from all these battery breakthrough announcements is the batteries.

With all these dozens of lithium battery break throughs, soon I will just have to change the hearing aid battery that powers my flying electric car. Hopefully, they will come in a twelve pack. "Star Trek" was right, dilithium crystals will power the future. Where's that article about warp drive?

This publication should contact every one they've featured in a battery breakthrough article and organise a meeting so they can hash out a best solution and get it into production.

I agree with the pessimism regarding yet another development but no new product. They need advice from industry experts to assess scalability or if it is too expensive for commerialization. I've studied the huge gap between the lab and the market (academia and manufacturing). I wonder if any of the automakers would fund the commercial product. 3x would be a pretty big deal.

Thanks Nick, pretty good synopsis strong on "improvements by a factor of x", and otherwise non-specific.

The relevant information of how much testing must occur prior to scaling up into production is not addressed. There are numerous issues with scale when manufacturing processes are so controlled in the lab, but at scale, results are sometimes quite different.

Keep on informing us of the innovative research - there is no such thing as irrelevant improvements or breakthroughs in Science, only in popular consumption of science.

These breakthroughs are the small steps needed to get to battery technology that will move the planet. Just because they don't all create superbatteries in a flash doesn't mean this research isn't important and helps other researchers move forward.

The least the article could have done is give the actual energy density and power density instead of the ambiguous "several times more power"

Why do they continue to use a rare element that is expensive for batteries? Find a better element.

I want some of those 437kWh hearing aid batteries Nobody was talking about. What a powerwall!
