Until it leaves a lab I am going to lump this with the other 10,000 battery improvements that never get anywhere.

  Sure, but before you do that could you approve our grant funding?

  Why is that in every battery article, people come to be dismissive? If you don't care, why click on the article?

    Because it's just noise that never gets anywhere. You get excited at the data/news, go check out the comments for discussion and find out 10 reasons why it's all bunk. As the old adage goes -- fool me once..

      Batteries have improved leaps and bounds over the last decade. Where do you think that came from?

  Batteries are better because of all those improvements. >In fact, gains in the amount of energy [lithium-ion batteries] can store have been on the order of five percent per year. That means that the capacity of your current batteries is over 1.5 times what they would have held a decade ago… A study may identify a way to significantly improve one characteristic, generating an exciting top-line conclusion. But the design may be impractically poor in some other way. While battery researchers learn from what does and doesn’t work, this means that a lot of laboratory batteries you may read about will never hit the market…A recent study noted that “the real price of lithium-ion cells, scaled by their energy capacity, has declined by about 97 percent since their commercial introduction in 1991.” The early lithium-ion cells in the 1990s were around $3,000 per kilowatt-hour. By the early 2000s, that was nearer to $500 per kilowatt-hour.[1] [1] https://arstechnica.com/science/2021/05/eternally-five-years-away-no-batteries-are-improving-under-your-nose/ https://arstechnica.com/science/2021/05/eternally-five-years...
