Chapter 285: The biggest change in the lithium battery industry! (2nd Month Pass)

"Professor Allen, it's a pleasure to meet you."

In the Santa Barbara branch campus of the University of California, the media reporter of the science and technology blog warmly shook hands with the old Nobel Prize in front of him and said hello.

The old man smiled and shook his hand, nodded and said, "Sit down, my assistant has already told me." ”

After chatting for a while, the media reporter of the science and technology blog said: "Professor Allen, have you read the paper on the lithium dendrite problem that has been very popular on ARIXV recently?" I heard that Professor Xu developed a solution to the lithium dendrite problem? ”

Alan Haig nodded and said, "I've read it, it's a pretty wonderful paper, and we are currently repeating the experiment according to the method in the paper." ”

The reporter asked with some surprise: "Is it right?" ”

Professor Alan Haig shook his head and said, "I don't know yet, and I can't guarantee that it will solve the lithium dendrite problem until the results of the experiment come out." ”

"But ....."

After a moment's hesitation, the old man continued, "Theoretically, it's most likely right. ”

"And according to my understanding, there have been many universities or laboratories that have replicated this achievement, and from the preliminary tests, this artificial SEI film can inhibit the growth of lithium dendrites to a large extent."

Hearing this, a media reporter from a science and technology blog quickly asked: "If the lithium dendrite problem is solved, what kind of changes will it bring to our lives?" ”

Professor Allen pondered for a while and then said slowly: "The lithium dendrite problem is the biggest one in lithium batteries, and it is of great significance to the development of lithium batteries. ”

"First of all, it is certain that if the lithium dendrite problem can be solved, we will get lithium batteries with higher capacity."

"After all, the capacity of lithium-ion batteries mainly depends on the quality and ratio of positive and negative active materials, which in turn determine the energy density of the battery."

"Whether it is the lithium-ion battery we use now, or the lithium-sulfur battery that is being developed all over the world, or even the lithium-air battery that is still in the theoretical stage, the problem of lithium dendrite formation cannot be avoided."

"For a very simple example, the lithium batteries currently circulating on the market, the anode materials of the battery mainly include natural graphite materials, artificial graphite materials, silicon-based and so on."

"The theoretical specific capacity of graphite is only 372 mah/g, but if the graphite is replaced with lithium metal, its capacity can reach 3860 mah/g, which is more than ten times higher."

The old man's concise words and comparisons made the media reporter who was interviewing gasp, and a shocked expression appeared on his face.

If you describe it in other ways, you may not be able to achieve this effect.

But the three-digit and four-digit comparisons are probably clear to anyone.

After the shock, the media reporter of the tech blog quickly asked with excitement in his eyes: "In other words, if the lithium dendrite problem is solved, we will get a battery with ten times the range?" ”

Alan Haig shook his head and said, "It can't be converted like this, because there are many other things that determine the capacity of the battery, such as electrolyte, cathode material, etc. ”

"But it is foreseeable that if the problem of lithium dendrite formation is solved, I am afraid that it will not take a year or two for us to have at least a battery that has more than double the current battery life."

"Think about it, doubling the time spent on mobile phones, and increasing the range of electric vehicles from less than 500 kilometers to 1,000 kilometers."

β€œ.........”

"Thank you very much, Professor Allen, for your help, that's all for today's interview."

After ten minutes of interviewing, the media reporter of the tech blog got the answer she needed, got up satisfied, and prepared to leave.

Just then, the door to the office was pushed open, and a young staff member hurriedly entered.

"Professor, we succeeded, and through that paper, we fabricated an artificial SEI film and tested it, and the test results showed that this artificial SEI film can indeed effectively solve the problem of lithium dendrite formation."

The young researcher's report stunned both the media reporters in the office and Professor Alan Haig.

Alan Haig stepped forward quickly and said, "What about the results of the experiment?" Let me see! ”

The young man handed over the report he was carrying, and Professor Allen took the document and quickly flipped through it.

From the scanning electron microscope images on the report file, it is clear that lithium ions are gathered on one side of the film on the artificial SEI film used for the experiment.

This is the most common phenomenon of lithium separation in lithium batteries, and the lithium ions in the electrolyte are concentrated in the positive and negative electrodes for various reasons during charging and discharging.

In the phenomenon of lithium precipitation, if the precipitated lithium ions have nucleation, then the precipitated lithium ions will continue to spread and grow like snowflakes or branches, and then form irregular dendritic crystals.

This crystallization is lithium dendrite, which will puncture the separator over time, and then cause problems such as spontaneous combustion and explosion of lithium batteries, which will pose a danger to users.

However, from the report in hand, it can be clearly seen that under this artificial SEI film, although the problem of lithium precipitation still occurs, lithium dendrites have not been formed.

The lethal nucleation reaction used to form lithium dendrites did not occur on it, or it was guided by this small artificial SEI film at the time of deposition.

These lithium ions precipitated from the electrolyte are more like bricks used to build a house, layer by layer on the side of the film in regular stacks.

Judging from the data, they restored the experiment, and the process and method of lithium deposition were exactly the same as the paper on Arxiv.

If you look at it from this aspect, there is no doubt that the problem of lithium dendrite formation has really been solved!

.......

Holding the report in his hand, Alan MiG's breathing became a little short.

Although I had heard that other laboratories had reproduced this artificial SEI film, it was completely different from verifying it myself.

Only by experiencing it yourself will you experience the shock in the middle.

Although he was a little puzzled, judging from the data table, the lithium evolution problem on the artificial SEI film seemed to be a bit serious and too fast, but under the shock of lithium dendrite formation, these are nothing.

The lithium dendrite problem has been solved, and the biggest change in the history of the lithium battery industry is about to happen!

"It's unbelievable! Lithium dendrites really didn't form ......."

Staring at the report in his hand, Alan Mig couldn't help but say to himself in shock.

On the other hand, the media reporter of the technology blog, who has not yet left, is keenly aware that this may be a new important information point, and quickly turns the voice recorder back on.

After waiting for Professor Alan MiG to come to her senses, she quickly stepped forward and asked, "Professor Alan, can I ask what is going on?" You've just been experimenting? ”

Alan MiG nodded and said, "Yes." ”

"Before you came, we were already conducting replication experiments on Professor Xu's paper, and just now, the results of the experiment have come out."

"The result? Did it work? A media reporter from a tech blog quickly asked.

Alan MiG nodded vigorously and said, "Yes, we succeeded!" ”

"In the experimental report, it can be clearly seen that lithium dendrites are not formed on the artificial SEI film, it is layered on one layer of the film in a regular manner, and will not pierce the film again, causing a short circuit."

"The lithium dendrite problem will be a thing of the past, and in the near future, it may only take a year or two or even less, and we will see mobile phones that have been used for a longer time, and we can also see electric vehicles with a range of up to one or two thousand kilometers, which will no longer be a fantasy!"

"This will be the biggest change in the history of the lithium battery industry!"

.......

I have to say that the tech blog did make a big news.

Of course, this is not their exclusive news.

There seems to be a common tacit understanding among the entire media press community, and a week after Xu Chuan threw the paper on Arxiv, media outlets large and small began to speak out.

"The change of the lithium battery era, the research of Professor Xu Chuan, a mathematician in China, may bring ten times the current capacity of the new lithium battery! 》

Shocked! The capacity of lithium batteries is about to increase tenfold! 》

Almighty Scholar! After the fields of mathematics, physics, and astronomy, the young professor has extended his hand to the field of chemical materials! 》

"Lithium battery long battery life to welcome a new breakthrough in the industry, China's famous scientist Professor Xu Chuan has developed a new artificial SEI film to solve the problem of lithium dendrite! 》

γ€Š........》

All kinds of news came overwhelmingly and quickly rushed to the hot searches of major platforms.

[Ten times more battery capacity? Where did the title party come from, disgusting! 】

[No, it may be true that it is not good this time, the lithium dendrite problem is solved, and it is really possible to increase the capacity of lithium batteries by ten times. 】

[The media and the news have reported it specially, and this should be true.] 】

[Did you read the name of the problem?] Professor Xu Chuan, is that the one I know? Or other scientists with the same name and surname? 】

[It's him!] 】

[But isn't the old man Kawajin engaged in mathematics? Why did you suddenly run to research lithium batteries? 】

Who knows? But what I can know is that maybe in a year, our mobile phone battery life can reach ten days and half a month, and new energy vehicles can also run two or three thousand kilometers on a single charge! 】

[Hiss~, don't say much, the god of Sichuan is awesome! 】

【Looking forward to it!】 】

[The stock speculation said that there is something to say, today's new energy sector is crazy about the rise of cats, and many of them have directly increased the limit, and I regret not buying it in advance! ] 】

[What are you, I just stepped on the horse a few days ago and just sold my shares in BYD! ] It's been almost three times in the past two days, Gan!

【.......】

........

On the other hand, under Xu Chuan's arrangement, the Chuanhai Materials Research Institute began to send invitation letters to manufacturers and media reporters interested in the battery industry at home and abroad after the heat rose.

Professor Xu Chuan, a well-known Nobel laureate and the real owner of the Chuanhai Institute of Materials, will hold a press conference on May 30 to give a speech on the problem of lithium batteries and lithium dendrite.

This news flew all over the world in an instant, attracting the attention of countless manufacturers.

Many car manufacturers and mobile phone manufacturers are trying to get an invitation, and even those financial companies that have nothing to do with the battery industry are trying to get an invitation.

Without him, because this press conference is far more than it seems on the surface.

Behind the scenes, there will also be an auction for the licensing of artificial SEI films for lithium-ion batteries, according to some of the manufacturers who received the invitation.

According to the current information from the scientific community, this new artificial SEI film can solve the problem of lithium dendrite.

Then, the battery industry, no, the battery industry and all related industries, such as mobile phones, computers, automobiles, drones, and even the military, etc., will usher in a major change!

Therefore, although many people do not believe that the lithium dendrite problem has been solved, there are also many manufacturers outside the battery industry who are still trying to find ways to get an invitation to participate in this press conference.

I'm not afraid of 10,000, I'm afraid of what if, if this is true, and I miss it, I will miss a huge market with a trillion scale!

Even, to put it more seriously, this will affect the development and life of countless manufacturers inside and outside the industry!

Some companies may take off in this development, while those that do not keep up with the times and get on board are at risk of dying.
