"First fully rechargeable carbon dioxide battery with carbon neutrality"

Lithium-carbon dioxide batteries are attractive energy storage systems because they have a specific energy density that is more than seven times greater than commonly used lithium-ion batteries. However, until now, scientists have not been able to develop a fully rechargeable prototype, despite their potential to store more energy.


https://www.sciencedaily.com/releases/2 ... 101331.htm

I'm not sure if this has been posted here or not. 7 times the energy density is a game changer if they can get the charge cycles out of the chemistry.

The article suggests they have demonstrated 500 cycles? Although "charge-recharge" cycles is an odd way of stating it.

Any technical oddity in press releases if often a sign of bullshit and wapor ware.
The press release itself is just a fraud and the intent is raising investment capital.

From this article:
https://www.forbes.com/sites/alanohnsma ... 5a17e4157a
Nikola Motor, the Phoenix-based startup that wants to disrupt trucking with futuristic electric semis powered by hydrogen, says it has developed a new type of battery cell with double the energy density, only 40% of the weight and half the cost of current lithium-ion batteries used in Teslas and other consumer-market electric vehicles.

But it’s not providing many details for now, and public demonstrations won’t happen for about 10 months.

Battery packs using the new cells, which don’t use nickel, cobalt and other metals typically found in 2170 lithium-ion cells favored by Tesla, could boost range for current electric passenger cars from 300 miles per charge to as much as 600 miles with “little or no increase to battery size and weight,” the company said. Nikola has subjected its cells to heavy-duty testing and says that charging and depleting them “over 2,000 times has shown acceptable end-of-life performance.”
and
Many years of undelivered promises created considerable skepticism among auto engineers and executives, some of whom grouse about “liars, damn liars and battery suppliers.”
and maybe it's an investor scam:
Nikola has raised about $500 million to get its hydrogen fuel cell trucks into production, gaining a $3 billion valuation, and needs to raise considerably more to also build its own network of hydrogen fuel stations to power them.
We'll see........

So FuelCells for trucks is quite a practical idea, I don't know why Nikola wants to make fancy battery claims on top.

I can't believe the scams out there though, I saw this "Waterseer" titled video on youtube many times but it looked boring so I never watched it, but then YouTube autoplay/next-video played it, it's hilarious and fascinating how cheeky the scammers are out there.
It was all the people who paid money on IndieGoGo Crowdfund asking where is their water machine that really is the kicker.

When you see some "new amazing" battery tech company get swallowed by Tesla or some other automaker for $50million you have to be a bit dubious that the tech was anything special.. If it could double lithium cell performance the tech would be worth billions.

But today I saw a headline worthy of this thread simply because of the raw size of the money changing hands...

It's not a press release it's an article on the paper published in Advanced Materials: https://onlinelibrary.wiley.com/doi/abs ... .201902518

Numerous sites have published the article
https://www.google.com/search?sxsrf=ACY ... 9JhgUNI8sA

I'm not sure how legitimate the Advance Materials journal is but it's been around for 30 years. The paper itself is from the University of Illinois. I don't see any investment opportunities being presented.

As for the charge/recharge cycles reference it doesn't seem all that unusual. From what I've read it's a more specific reference than "discharge cycles"; "discharge cycles" seems to refer to a 100% to 0% range while charge/recharge cycles seems to refer to a narrower more usable range.

I wouldn't classify this as fraud, it seems much more inline with the "wishful thinking" that typically follows these types of journal articles. Somewhere in the fine print the practical use of such technology is prohibitive for some reason or the current state of development means even if it does pan out it could be decades before it come to market, if at all. In the interim something else could come along and this technology gets shelved.

Interesting paper... looks scientifically sound and the authors from UIC, Argonne and Purdue are credible.
Swagelock cells have been built and tested based on theoretical calculations of the novel ingredients (Li as anode, CO2 as cathode with MoS2 as catalyst and a ionic liquid/dimethyl sulfoxide electrolyte with a (still) F containing Li-salt). Voltage around 2.9V with a high overvoltage needed for charging (at around 4.5V).
My impression: Far from being ready for the mass market in a short time, but a precious contribution to the battery world and an interesting potential on a longer time scale.

IBM claim to have the next big deal in batteries..
https://www.techrepublic.com/article/ib ... 2449370598
According to IBM, tests of the new battery "proved it can be optimized to surpass the capabilities of lithium-ion batteries in a number of individual categories including lower costs, faster charging time, higher power and energy density, strong energy efficiency and low flammability."

That faster charging time IBM mentioned is one of the standouts of its report on this battery breakthrough: It can reportedly reach an 80% charge in just five minutes, all without compromising discharge capacity.

Along with that impressive recharge rate are several other performance improvements, IBM said:

It can reach a power density of more than 10,000 watts per liter;
It can reach an energy density of more than 800 watt hours per liter, which is comparable to modern lithium ion batteries;
It has an energy efficiency (defined by IBM as "the ratio of the energy to discharge the battery over the energy to charge the battery") of over 90%.

researcher's goofin' off is why it's taking so long for a new battery breakthrough.
made his house of silicon while he made the snowman of particles that are used in lithium-ion battery research, including nickel, cobalt and aluminum.

Hey first time poster, LONG time lurker (~2009).

Did some searching of this thread, did not see this PR about Tesla corp. battery research, so here it is:

https://pv-magazine-usa.com/2019/09/09/ ... n-battery/

Jeff Dahn, Tesla’s main battery research partner, seems to have a substantial background in real-world battery tech-to-market.

Do a search for: "tesla 20 year batteries" and "Jeff Dahn" for more info.

Some advances in lithium-sulfur batteries. LiS has the potential for twice the energy density of present batteries and lower cost.

The problem has been a large amount of expansion of the sulfur part during discharge, which breaks up the electrode structure. The new approach is to cover nano particles of sulfur with a 'shell' material then dissolve away part of the sulfur inside so there is room for expansion without cracking the shell.

Loosing 25% capacity after 200 cycles is not impressive, rather lousy actually.
But they don't seem to care about that small "issue".
Easily fixed they might think, but probably not and the waiting for truly good LiS batteries continues....

New little breakthrough in preventing oxygen release from reacting with electrolytes, involving a molten salt treatment to the Li-rich cathode.

New anode tech: coat a porous silicon anode in alumina, then let the alumina saturate with lithium. It becomes a protective catalyst layer for the cathode, and keeps max capacity stable over 100's of cycles. So, not only do we get a decent jump in capacity, but cycle life as well.
