Its ' interesting ' watching people that havent got a clue what they arer talking about talking and speculating about what they dont have a clue about again >So has the "Holy Grail of materials science" now been found? Many more steps are still needed to verify it. "There are still very good reasons to be skeptical," says Karsten Held. "I wouldn't bet my money at the moment that this is indeed a high-temperature superconductor - at least not at 1:1 betting odds. But the results at least show that LK-99 is indeed a very interesting material that deserves closer attention. It remains exciting." https://www.tuwien.at/tu-wien/aktue...uf-revolutionaeren-hochtemperatur-supraleiter
Interesting is the way how it happens. Publishing that at physics archive (arXiv) is very ambitious. Actually the chance to 'lose' is great. When publishing at a scientific journal, you usually have to undergo a peer-review and you can be sure your work has been validated. Anyway it's an interesting approach 'open source research'. One publishes something and now many others try to reproduce...maybe even to improve. And yes people don't have a clue about because they cannot have one at all yet. The published work is not detailed enough. Regardless what will be the outcome, it has united some researchers making efforts now.
I think its amazing how you talk about science and what it proves ....... and what that proof is worth .......... after denying , and desputing that science has any value in the corona thread .
Don't forget that a relevant share of earth's population can't afford/don't have access to that "luxury" in 2020s https://www.who.int/news-room/fact-sheets/detail/sanitation Perhaps a random Musk/Bezos/Gates could buy one for each of those 1.7 Billions of people, while staying among richest the people of the planet club.
Bat thinks big cities like San Francisco, Los Angeles and NY City would have enough toilets? Bat think pooping on sidewalks and streets is a choice :/
Do we need to reduce pollution, to begin with?!? https://www.theguardian.com/society/2023/aug/07/air-pollution-linked-rise-antibiotic-resistance-imperils-human-health
Just a quick update. LK-99 is no superconductor. It's even an insulator with millions of Ohms And the pure stuff looks like purple colored glass. The 'effect' was something like ferromagnetism due to impurities. And they also made clear which lesson to learn (I also said scientists usually test tiny samples first!): The dream is over for now... LK-99 isn’t a superconductor — how science sleuths solved the mystery (nature.com)
I'm afraid the whole matter will turn in an endless vaccine like online debate https://www.tomshardware.com/news/lk-99-patent-update-suggest-it-could-work
No, at superconductors there is only one important value. TC. (Transition temperature) and there is a real debate, because no side is censored. The Max Planck Institute is a reputable institute, they would lose reputation if they should be wrong. Means there is no drop at renitency at all. They also reasoned why they had a drop at renitency (Cu2S as impurity) Now it's up to the inventors to counterargument. But IMO those are arguments which are strong... The inventors can now provide a more precise instruction how to synthesize to get a new formula and the institute can redo it. But pure Pb8.8Cu1.2P6O25 is not a superconductor.
Sodium? New chemistry/materials for various batteries? Carbon/carbon chemistry? Apparently 100% recyclable and biodegradable... How about Throium?!? (Brrr...) Electrically fueled ships??? Nuclear diamond battery??? NASA Reveal New Sulfur Selenium Solid-State Battery > aviation could use it...???
I would be careful with such 'science' videos. YouTube is full of twisted facts and exaggerations / sensations. Always check if they have links as references at the info box. For instance: Nuclear Diamond Battery of NDB. That video has NO source at all! If you check the source directly, there is nothing about a final product. News | NDB A nuclear battery gets its energy from nuclear decay. Means, it constantly produces energy, no matter if you consume it or not. Those need no re-charge, they constantly deliver energy, but usually a low amount over a very long period of time. (depends on certain decay) diamond-batteries | Cabot Institute for the Environment | University of Bristol Sodium batteries, though, will be soon commercially available, also mixed batteries (Li+ / Na+) Also 'Sodium' or 'Lithium' alone are not specific enough. A battery of that kind consists of at least 4 parts: Anode, cathode, electrolyte and a separator. There are at least 3 major kinds of Lithium batteries: Lithium Iron Phosphate (LiFePO4) The common type Lithium Manganese Oxide (LiMn2O4) The fast charging type Lithium Nickel Manganese Cobalt Oxide (CoLiMnNiO+)The high energy density type / longer LifeCycle.
Yes, you can see in each video that almost none of these are fully ready but that the research and development are continuing! That is the point here, not yet "xyz destroyed the market of..." And mixing of various chemistries has also been presented in some detail... No, you will not see any serious sources, as these are... secrets... Not a lot here seen is fundamental open source research... Sadly...
Look, it's happening - the new chemistry, allegedly faster, safer, more durable... https://chargedevs.com/newswire/cat...p-battery-to-start-mass-production-this-year/ CATL launches fast-charging LFP battery, to start mass production this year Posted August 25, 2023 by Charles Morris & filed under Newswire, The Tech. CATL, the world’s largest EV battery maker and a major Tesla supplier, has launched a new lithium iron phosphate (LFP) battery that it claims can add 248 miles of range in 10 minutes of charging. The company says its new Shenxing battery (named for an ancient Chinese phrase having to do with speed) will deliver up to 434 miles of range on China’s CLTC cycle. It supports 4C fast charging, which means it can charge at a current of 12 A above the diffusion limiting current. CATL says the new battery owes its speed to several in-house technologies, including accelerated extraction of lithium ions, an improved lithium-ion intercalation rate through fast ion ring technology, a multi-gradient layered electrode design, a new superconducting electrolyte formula, and an ultra-thin and safer separator. Automakers are increasingly turning to LFP cells, which tend to be cheaper and more durable than cells using other chemistries. Traditionally, the drawbacks of LFP are lower energy density and poorer cold-weather performance, but CATL says these are no longer issues. According to the company, the Shenxing LFP battery can achieve fast charging even in temperatures as low as 14° F. CATL says the Shenxing battery is expected to enter mass production in China by the end of this year, and the first EVs equipped with the new battery will launch in the first quarter of 2024. “We hope that, through continuous efforts to improve technology and reduce costs, Shenxing will become a standard product available for every electric vehicle,” said Gao Han, Chief Technology Officer of CATL’s E-Car Business. Thermal runaway? Also improved... https://chargedevs.com/newswire/fre...tomized-3d-thermal-barriers-for-ev-batteries/ And silicon may finally have been given a proper leg-up with this nano-scale carbon layer coating, which is consistent: https://chargedevs.com/newswire/neo...-uniform-nanocoating-manufacturing-technique/ NEO Battery Materials develops a uniform nanocoating manufacturing technique Posted August 25, 2023 by N. Mughees & filed under Newswire, The Tech. NEO Battery Materials, a silicon anode material manufacturer, has created a nanocoating manufacturing technique with its patented NBMSiDE silicon anode materials. NEO can create uniform nanocoating layers from uniformly-coated silicon particles to improve NBMSiDE’s performance. NBMSiDE capacity retention was previously poor due to the mechanical degradation of non-uniform coatings. NEO says that this uniform nanocoating manufacturing will allow robust capacity retention and coating thickness control during commercial testing, and its optimized one-step process can provide 70% cheaper silicon anodes than competitors. The process makes it possible to produce uniform coatings on spherical and edged silicon particles. “Achieving uniform coating layers on the nano-scale is a difficult task for a company of any size that handles chemical products,” said Dr. S.G. Kim, CTO of NEO. “Especially for NEO, our metal silicon inputs take on a plate-shaped structure, which adds to the technical hurdle of enabling uniform coatings. However, by achieving this uniform coating capability through an additional solution process, we have made an accomplishment and have amassed great interest from third-party industry experts and players.”
With Bidonomecis there aren't very many New ICE model cars and trucks on the lots around here because people can't afford them. EVs don't stand a chance https://www.westernjournal.com/ev-f...ric-vehicles-learning-harsh-economics-lesson/
What you can do is looking for newly issued patents. They have to be public. The only drawback is that we do not know which patent will be the one that provides the future commercial type of battery. I think it's not different than meds development. We also issue patents to protect our field of research.., but what will be a new certain drug / medicine, we ourselves do not know in advance. Interesting that they go back and rely on the 'classic / common' type lithium iron phosphate. Seems there is still potential for improvement. Curious if they really could eliminate the weaknesses...low energy density and low temperature issues.
