Chapter 285 The biggest change in the lithium battery industry!
"Professor Allen, nice to meet you."
At the Santa Barbara campus of the University of California, a media reporter from a science and technology blog enthusiastically shook hands with the Nobel laureate in front of him and said hello.
The old man smiled and shook hands, nodded and said: "Sit down, my assistant has already told me."
After a brief chat, the media reporter from the technology blog said: "Professor Allen, have you read the paper about the problem of lithium dendrites that has been very popular on arixv recently? I heard that Professor Xu developed it
Is there a way to solve the lithium dendrite problem?"
Alan Haig nodded and said: "I have read it. It is a very exciting paper. We are currently repeating the experiment based on the method in the paper."
The reporter asked in surprise: "Is it right?"
Professor Alan Haig shook his head and said: "We don't know yet. Before the experimental results come out, I can't guarantee that it will definitely solve the problem of lithium dendrites."
"but....."
After hesitating for a moment, the old man continued: "Theoretically, it is very likely to be right."
"And according to my understanding, many universities or laboratories have already replicated this result. Judging from preliminary tests, this artificial SEI film can inhibit the growth of lithium dendrites to a great extent.
"
Upon hearing this, a media reporter from a technology blog quickly asked: "If the lithium dendrite problem is solved, what changes will it bring to our lives?"
Professor Allen pondered for a moment and then slowly said: "The problem of lithium dendrites is the biggest one in lithium batteries, and it is of great significance to the development of lithium batteries."
"The first thing that is certain is that if the lithium dendrite problem can be solved, we will get lithium batteries with higher capacity."
"After all, the capacity of a lithium-ion battery mainly depends on the quality and ratio of positive and negative active materials, and the positive and negative materials determine the energy density of the battery."
"Whether it is the lithium-ion battery we are using now, the lithium-sulfur battery being developed around the world, or even the lithium-air battery still in the theoretical stage, the problem of lithium dendrite formation cannot be avoided."
"To give a very simple example, for lithium batteries currently on the market, the negative electrode materials of the battery mainly include natural graphite materials, artificial graphite materials, silicon-based materials, etc."
"The theoretical specific capacity of graphite is only 372mah/g, but if graphite is replaced with lithium metal, its capacity can reach 3860mah/g, which is more than ten times higher."
The old man's succinct words and comparisons made the media reporters who were interviewing take a breath and show shocked expressions on their faces.
If we describe it in other ways, it may not achieve this effect.
But when comparing three-digit numbers with four-digit numbers, I’m afraid everyone knows it.
After the shock, the reporter from the technology blog quickly asked with excitement in his eyes: "In other words, if the problem of lithium dendrites is solved, we will get a battery with ten times the endurance?"
Alan Haig shook his head and said: "You can't convert it like this, because there are many other things that determine the battery capacity, such as electrolyte, cathode material, etc."
"But it is foreseeable that if the problem of lithium dendrite formation is solved, it may not take more than a year or two for us to have batteries that can at least double the current battery life."
"Think about it, the time you can use your mobile phone has doubled, and the cruising range of an electric car has increased from less than 500 kilometers to 1,000 kilometers. What is the concept?"
"..."
"Thank you very much for your help, Professor Allen. That concludes today's interview."
After more than ten minutes of interviews, the media reporter from the technology blog got the answers she needed, and stood up with satisfaction and prepared to leave.
At this moment, the office door was pushed open, and a young staff member hurriedly rushed in.
"Professor, we succeeded. Through that paper, we created an artificial SEI film and tested it. The test results show that this artificial SEI film can indeed effectively solve the problem of lithium dendrite formation."
The young researcher's report stunned the media reporters and Professor Alan Haig in the office.
Alan Haig walked forward quickly and said: "Where are the experimental results? Let me take a look!"
The young man handed over the report he was carrying, and Professor Allen took the document and quickly read through it.
Judging from the scanning electron microscope images in the report document, on the artificial SEI film used for the experiment, it can be clearly seen that lithium ions are accumulated layer by layer on one side of the film.
This is the most common lithium precipitation phenomenon in lithium batteries. Lithium ions in the electrolyte accumulate in the positive and negative electrodes for various reasons during charging and discharging.
In the lithium precipitation phenomenon, if the precipitated lithium ions nucleate, then the precipitated lithium ions will continue to spread and grow like snowflakes or branches, and then form irregular dendrites.
This kind of crystal is lithium dendrite, which will pierce the separator over time, causing spontaneous combustion, explosion and other problems of lithium battery, posing danger to users.
However, from the report in hand, it is obvious that under this artificial SEI film, although the problem of lithium precipitation still occurs, lithium dendrites have not formed.
The fatal nucleation reaction used to form lithium dendrites did not occur on it, or it was guided by this small artificial sei film during deposition.
These lithium ions precipitated from the electrolyte are more like bricks used to build a house, layer by layer, regularly stacked on one side of the film.
Judging from the data, they restored the experiment, and the process and method of lithium deposition are 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 Miguel's breathing became a little rapid.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Although I have heard that other laboratories have reproduced this kind of artificial SEI film, I heard that it is completely different from verifying it myself.
Only by experiencing it yourself can you understand the shock.
Although he had some doubts, judging from the data table, the lithium evolution problem on the artificial SEI film seemed to be serious and too fast, but under the shock that lithium dendrites were not formed, these were 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 are really not generated..."
Staring at the report in his hand, Alan Miguel couldn't help but mutter to himself in shock.
On the other side, the media reporter from the technology blog who had not yet left was keenly aware that this might be a new important information point, and quickly reopened the recorder.
After waiting for Professor Allen Meagher to come to her senses, she quickly stepped forward and asked: "Professor Allen, can I ask what happened? You were doing an experiment just now?"
Alan Miguel 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 came out."
"What was the result? Was it successful?" a media reporter from a technology blog quickly asked.
Alan Miguel nodded vigorously and said: "Yes, we succeeded!"
"In the experimental report, it can be clearly seen that lithium dendrites are not generated on the artificial sei film. They are regularly stacked layer by layer on the film and will no longer pierce the film and cause short circuits."
"The problem of lithium dendrites will be a thing of the past. In the near future, it may only take one or two years or even less. We will see mobile phones that last longer, and we will also see electric vehicles with a battery life of one or two thousand kilometers."
Cars, these will no longer be fantasies!”
“This will be the biggest change in the history of the lithium battery industry!”
.......
I have to say that technology blogs have indeed made big news.
Of course, this is not their exclusive news.
The entire media and journalism community seemed to have a common understanding. A week after Xu Chuan posted his paper on arxiv, media outlets of all sizes began to speak out.
"Changes in the lithium battery era, the research of Chinese mathematician Professor Xu Chuan may bring about a new lithium battery with ten times the current capacity!"
"Shocking! The capacity of lithium batteries is about to increase tenfold!"
"All-round scholar! After the fields of mathematics, physics, and astronomy, this young professor has extended his hands to the field of chemical materials!"
"The long battery life of lithium batteries welcomes new breakthroughs in the industry. Professor Xu Chuan, a famous Chinese scientist, has developed a new artificial SEI film to solve the problem of lithium dendrites!"
"......."
All kinds of news came in overwhelmingly, and quickly hit the hot searches on major platforms.
[Improved battery capacity ten times? Where did the headlines come from again, disgusting!]
[No, it might be true this time. The lithium dendrite problem has been solved, and it is really possible to increase the capacity of lithium batteries tenfold. 】
[The media and news have specially reported it, so this should be true. 】
[Have you seen the name of the person who solved the problem? Professor Xu Chuan, is he the one I know? Or is it another scientist with the same name? 】
【It’s him!】
[But isn’t Mr. Sichuan God engaged in mathematics? Why did he suddenly go to study lithium batteries? 】
[Who knows? But what I do know is that maybe in a year our mobile phones will have a battery life of ten and a half days, and new energy vehicles can also run two to three thousand kilometers on a single charge!]
[Hiss~, I won’t say more, Sichuan God is awesome! 】
【look forward to!】
[Stock speculators have something to say. The new energy sector has gone crazy today. Many of them have reached their daily limit. I regret not buying in advance! 】
[What are you talking about? I just sold my BYD shares a few days ago! It has almost doubled by 30% in the past two days, hey!
】

........
On the other hand, under the arrangement of Xu Chuan, the Sichuan-Hai Materials Research Institute began to send invitations to manufacturers and media reporters at home and abroad who were interested in the battery industry.
Professor Xu Chuan, the famous Nobel Prize winner and the real boss of the Sichuan-Hai Materials Research Institute, will hold a press conference on May 30th to give a lecture on the problems of lithium batteries and lithium dendrites.
The 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 letter, and even financial companies that have nothing to do with the battery industry are trying to get an invitation letter.
Nothing else, because this press conference is far more than what it seems on the surface.
According to some manufacturers who received the invitation letter, behind the scenes of this press conference, there will also be an auction for patent licensing of artificial SEI films for lithium-ion batteries.
If the current news from the scientific community is followed, this new type of artificial SEI film can solve the problem of lithium dendrites.
Then, the battery industry, no, the battery industry and all related industries, such as mobile phones, computers, automobiles, drones, and even military industries, 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 invitations to attend this press conference.
Don’t be afraid of 10,000, just be afraid of the unexpected. If this is true and you miss it, you will miss a huge market worth trillions!
Even more seriously, this will affect the development and lives of countless manufacturers inside and outside the industry!
Some companies may take off in this development, while companies that fail to keep up with the times and get on board may die.
