Researchers at Yale and Donghua University in China have developed a new process for creating lithium metal that may boost the energy and capacity of rechargeable batteries.
Lithium metal is considered the best option as a material for anodes in high-energy batteries, the researchers said, because of the metal's high potential for providing large amounts of energy and capacity in a given mass. Yet existing lithium metal electrodes, limited by low capacity and utilization efficiency, have not come close to reaching that potential.
In a new study May 14 in the journal Proceedings of the National Academy of Sciences, a team led by Yale's Hailiang Wang describes a new approach to creating more efficient lithium metal electrodes. The process yields a protective layer that enables lithium metal anodes to be efficiently discharged and charged at high capacities.
Based on the new process, the researchers constructed a battery cell that outperforms other laboratory-scale battery cells, as well as state-of-the-art lithium-ion batteries on the market.
Hailiang Wang is an assistant professor of chemistry and a member of the Energy Sciences Institute at Yale's West Campus. The first author of the study is Qiuwei Shi, a graduate student at Donghua and visiting student at Yale. Additional authors are Yiren Zhong and Min Wu from Yale and Hongzhi Wang from Donghua.

Three countries have 90% of the world’s known reserves and Afghanistan ain’t one of them.
These and cancer cure articles belong in the Cold Fusion file.
In June 2010, The New York Times reported that American geologists were conducting ground surveys on dry salt lakes in western Afghanistan believing that large deposits of lithium are located there. “Pentagon officials said that their initial analysis at one location in Ghazni Province showed the potential for lithium deposits as large as those of Bolivia, which now has the world’s largest known lithium reserves.”[52] These estimates are “based principally on old data, which was gathered mainly by the Soviets during their occupation of Afghanistan from 1979–1989”. Stephen Peters, the head of the USGS’s Afghanistan Minerals Project, said that he was unaware of USGS involvement in any new surveying for minerals in Afghanistan in the past two years. ‘We are not aware of any discoveries of lithium,’ he said.”[53]

Yep. These things never make it to market.
That the automobile has practically reached the limit of its development is suggested by the fact that during the past year no improvements of a radical nature have been introduced.

A concern: lots of energy stored in a very small volume. Density is the design goal. If compromised, it had better fail safely.

Batteries improve slowly due to incremental changes from a few legitimate researchers.
These publicity articles are crap. There’s hundreds or maybe thousands of them that never amount to anything except to get funding for more worthless research.
“These publicity articles are crap.”
Dude, you are hopeless.
Tell you what. Go back in the Internet archive a few years. Go through the hundreds of publicity articles claiming a battery breakthrough and tell me and the rest of the world how many made it to market.
And if you attack me again I’m going to let you have it.

Dude, you are hopeless. It was physics.org discussing a national academy of sciences paper.
“Batteries improve slowly due to incremental changes from a few legitimate researchers.”
Dude,
1. This is an incremental change, and
2. These are legitimate researchers
Dudette,
It’s not an incremental change that made it to market.
Here’s a publicity release from 2009:
The days of waiting hours to charge a mobile phone or laptop computer could soon be over because of research that could transform battery technology in as little as two years.
Scientists in the United States have invented a battery that can charge in seconds, promising a revolution in power storage that could also help green cars and renewable energy.
The advance allows lithium-ion batteries, the standard variety used in consumer electronics and cells for electric or hybrid vehicles, both to charge and discharge stored energy more quickly than at present.
This should lead to smaller, lighter batteries for mobile phones and other devices, which can be fully charged when plugged in for a few seconds.

Dude, if you can’t see the difference you are media and technology challenged...
“”It’s not an incremental change that made it to market.”
Dude, things rarely go from published to market is negative time.

That’s why I gave an example from nine years ago.
And I can give many more. These battery claims don’t ever make it out of the lab.
Thanks for new info.............
Dudes, say what you will about the 18650 battery, but at least it’s an ethos.
