Any idea how nissan increased the 2018 nissan leaf cell capacity from the original 72 amp hours to some where around 120 amp hours with out making them any larger, with the same chemistry?

The new leaf with 2nd gen batt is a coal powered car in the most literal sense possible.

Honda's battery breakthrough ?
10x more energy density than actual Lithium battery ?

They like saying things like that...and then years pass and nothing ever comes of it. Whether or not they bother trying, or find the reality falls far short of their ridiculous promises...at any rate, they should all shut up until they have a battery cell in hand to demonstrate their claims. Anything else is just to get investors to throw money at them.

Honda would not really need investors.
Instead, they'd like to get rid of ties like they had for producing NiMH batteries for their hybrids, which was a Panasonic split-off joint venture with Toyota - but Toyota was getting the most and the best batteries out of it.
Renamed to Primearth, it is Toyota's party piece now, and going strong.

In the medical field, the researchers also do similar things, always claims that found this or that, and the large majority of the suposed great findings ends in nothing. But the researchers are always publishing papers, and even some failures can help some future projects.

I don't think they need to shut-up, but need more careful, or the press needs to be better, since a lot the of problem it's the way press turn the articles, with sensationalism.

Here one thing :

"The prospects are exciting, no doubt about it. But there are a few hurdles to be cleared first. For one thing, the anode and cathode of the prototype battery tend to dissolve completely in the electrolyte."
"That’s a problem, but the team is hard at work trying to find a solution. If they can solve the high operating temperature conundrum, making anodes and cathodes that don’t dissolve should be child’s play."

I refuse to visit the cult site cleantechnica. They propagate lies and censor questions; the very definition of a cult.

Research claims aren't worth paying attention to because they made ridiculous claims that will never be achieved, and they know it (or should know it if they were being objective).

Why isn't there ever a story about a new technique that improves battery capacity by 5%? That's a believable story, and that to me is exciting. 10x increase in battery capacity and instant recharging, and 1/10 the cost... none of that interests me because I'm not into unicorns.

Ars Technica is respectable IMHO, it sounds like cleantechnica is trying to borrow cred.

I always hoped the wood-tin battery would work out.

“The soft nature of wood fibers effectively releases the mechanical stresses associated with the sodiation process, and the mesoporous structure functions as an electrolyte reservoir that allows for ion transport through the outer and inner surface of the fiber,” scientists said.

The article is five years old.
