New John Goodenough battery with high (too high?) energy density
"Now John Goodenough, the 94-year-old father of the lithium-ion battery, is claiming a novel solution as a blockbuster advance."
"If it proves out, the invention could allow electric cars to compete with conventional vehicles on sticker price. The improbable solution, described in a new paper from Goodenough and three co-authors, has drawn intense interest from leading science and technology publications. He estimates that the solution could store five to ten times as much energy as current standard lithium-ion batteries."
"“If anyone but Goodenough published this, I would be, well, it’s hard to find a polite word,” Daniel Steingart, a professor at Princeton, told Quartz."

Re: New John Goodenough battery with high (too high?) energy density
Considering how many revolutionary battery technologies have been announced over the past 15 years that somehow still have not surfaced yet, I am not holding my breath for that one either.If it proves out...
Re: New John Goodenough battery with high (too high?) energy density
This makes me think part of the gains are the device also acting as a capacitor, and not just as a battery. Assuming they work, I hope a version of this is available to replace the battery in my Volt once it gets old enough to need replacing.in the abstract someone wrote:This strategy is demonstrated with a solid electrolyte that not only is wet by the metallic anode, but also has a dielectric constant capable of creating a large electric-double-layer capacitance at the two electrode/electrolyte interfaces. The result is a safe, low-cost, lithium or sodium rechargeable battery of high energy density and long cycle life.
edit: and reading over teh linked patent, it definitely looks like they have made (or tried to make) a combination battery/capacitor. very interesting.

Link to his paper published in the Journal of the American Chemical Society early in the article.

There's a link to his paper (published in the Journal of the American Chemical Society) early in the article.

Re: New John Goodenough battery with high (too high?) energy density
So, not really much new information here. Everything still looks inconclusive and potentially overhyped.

Re: New John Goodenough battery with high (too high?) energy density
No bold guess that Elon won't get a cell...The paper has drawn criticism from other battery researchers, who tell Axios one aspect of the new battery cells — the relative dielectric constant — is higher than ever before recorded in any material known to science.
Re: New John Goodenough battery with high (too high?) energy density
What makes you say that? From what I understand Musk has called for people to bring their new battery tech for review by Tesla.Munchausen wrote:No bold guess that Elon won't get a cell...The paper has drawn criticism from other battery researchers, who tell Axios one aspect of the new battery cells — the relative dielectric constant — is higher than ever before recorded in any material known to science.

Re: New John Goodenough battery with high (too high?) energy density
Why? A simple probability calculation: How many battery breakthroughs a week do we have? How many find their way into a working commercially available unit?What makes you say that? From what I understand Musk has called for people to bring their new battery tech for review by Tesla.
And in this particular case we do have a statement on a fundamental value of a parameter that the peers consider beyond reasonable limits.
This is mostly the case. If you take the time to sift through the publications you mostly find that they omit something or do their testing in a dubious way.
No mentioning that their battery needs to be kept at 80 C to function...Why do they test their beatiful new solid polymer electrolyte at 0,2 C and 30 C? No conductivity/temperature diagram, hmmm.. What happened to that Li-S battery with "excellent cyclability" on the 101 cycle? So they baked those Si nanospherules in Ar and 500 C for 24 h....? Why only half cell testing?
And so on.
What, however, is encouraging is the volume and breadth of the work. A lot better than 20 years ago. Energy storage is being taken seriously those days.
One day we might hear Elon yell "Halleluja, brothers and sisters, I have seen the light" on a press conferens. But probably not this time.
Re: New John Goodenough battery with high (too high?) energy density
Ah, that's what you meant. Misunderstood your earlier post.
Re: New John Goodenough battery with high (too high?) energy density
Your maths are a bit off there. The numerator should be “How many battery breakthroughs a week by the original inventor of the Li-ion battery”.Munchausen wrote:Why?

Re: New John Goodenough battery with high (too high?) energy density
I found a new article on this battery on IEEE Spectrum's website just now: https://spectrum.ieee.org/energywise/en ... ing-better The article is from just a couple months ago.
