PS: I can’t write the title anymore (7/10 for the alliance leader Gao Shan Liushui. The alliance leader’s update is finally almost finished. I’ll just finish it in the past few days. There are other updates that will be returned after this one is finished.)
As the time approaches May 30th, the ancient city of Jinling once again welcomes flights from all over the world.
The press conference of the Chuanhai Materials Research Institute is about to begin, and major battery manufacturers, research institutes, and even mobile phone manufacturers and automobile manufacturers have come to join in the fun.
With so many people attending, the venue originally prepared by Xu Chuan was no longer enough, so he borrowed a lecture hall from Nanjing University.
On May 30, the day the press conference was held, the lecture hall was packed with people and all seats were occupied.
Representatives of many manufacturers arrived at the scene early in the morning. On the one hand, they were preparing to attend the press conference in advance, and on the other hand, they were trying to see if they could get to Xuchuan.
If he can leave a good impression in front of this young expert in advance, the probability of obtaining the patent authorization for the artificial SEI film will naturally be higher.
Of course, it was not just these manufacturer representatives present.
In addition to them, many researchers in the field of materials also came over. Although the Sichuan-Hai Materials Research Institute did not send them invitation letters at first, these people still came over on their own initiative.
What these scholars in the field of materials research are not concerned about is who will eventually receive the patent authorization for the artificial SEI film. What they care about is what is shown in the paper.
That mathematical model established for the development of chemical materials!
Many scholars in the field of materials, after reading the paper, immediately noticed the mathematical model method used in the paper. This can alleviate a lot of material research and development work to a certain extent, and even help eliminate and select some unsuitable and adaptive materials in the research and development process.
Although it is normal to use mathematical models to assist in materials research and development.
But the paper posted on Arxiv shows something completely different.
Different from the mathematical model used in the research and development of materials, it seems to be reprocessed from the atomic and molecular level of the material and the properties of the material.
Some researchers quickly realized that this might be a new thing, and Professor Xu Chuan was able to find the key to solving the lithium dendrite problem within a few months, which was probably based on this mathematical model.
Therefore, almost all scholars who noticed this detail called the Sichuan-Hai Materials Research Institute and asked for an invitation letter.
At ten o'clock in the morning, Xu Chuan arrived at the lecture hall on time and walked in from the main entrance.
Noticing his figure, the noisy voices in the lecture hall instantly fell silent, and everyone's eyes looked at him warmly and expectantly.
Xu Chuan walked up to the reporting stage as usual and looked at the crowd in the audience.
After trying the microphone, he said clearly: "First of all, welcome all of you who have traveled thousands of miles to attend today's press conference."
“The theme of today’s report is the launch of artificial SEI film products.”
While talking, Xu Chuan opened the PPT copy prepared in advance.
"Those who can come here today, I believe that everyone has a certain understanding of the problem of lithium dendrites, so I won't go into those easy-to-understand theories."
"As for the paper I published on 'Carboxymethyl cellulose-lithium fluorocarbon compound material' to guide lithium ion deposition in lithium batteries and solve the problem of lithium dendrite formation, I believe everyone has understood it before coming here, and even most of them have Some laboratories should have repeated relevant experiments and obtained the data they want.”
"So, even though my paper has not been published in a professional journal yet, everyone knows that it is correct and has successfully solved the lithium dendrite problem."
"What I want to talk about next is, on the one hand, the performance of this artificial SEI film. On the other hand, it is the broad prospects for the lithium battery industry after the problem of lithium dendrites is solved."
"OK, let's get down to business."
".The artificial SEI film manufactured through nanotechnology recombination can effectively inhibit the formation of lithium dendrite pronuclei, and guide the lithium ions to be deposited in an orderly manner on one side of the film."
On the podium, Xu Chuan talked eloquently.
In fact, whether he is talking about the excellent performance of artificial SEI films or the broad prospects of the lithium battery industry, it is all about selling the patents in his hands at a good price.
If not, why would he waste his time doing this kind of press conference.
"After solving the problem of lithium dendrites, the battery capacity of lithium batteries in the world today can be increased by several orders of magnitude. Not to mention many, just replacing the negative electrode material from the current graphite to lithium metal is enough to improve the battery The capacity has been increased several times.”
"Think about how our world will change when the battery capacity increases several times. Mobile phones can last more than a week! The mileage of electric vehicles doubles." Xu Chuan gave a passionate speech on the stage.
Under the stage, the eyes of countless spectators were shining with light.
In fact, those who can sit here today, aside from those scientific researchers, do not need Xu Chuan to tell them what changes will be brought about by increasing the capacity of lithium batteries.
The important thing is not the report meeting, but the auction for the artificial SEI film patent authorization after the report meeting!
He did not waste too much time at the press conference. In less than half an hour, Xu Chuan began to wrap up.
"That concludes today's press conference."
"If you have any questions about the artificial SEI film developed by our Chuanhai Materials Research Institute, you can ask them."
As soon as he finished speaking, someone in the audience stood up with their hands raised.
Xu Chuan motioned to the staff to hand over the microphone.
The person who asked the question was a middle-aged man wearing a plaid shirt. He didn't seem to be a member of the manufacturer.
"Hello, Professor Xu, I am Evans Jerry, a researcher at the German Federal Institute for Materials Research. I have read the paper you uploaded to the arxiv preprint website."
"In your paper, I found that your research on this artificial SEI thin film material used a new mathematical model. It seems to calculate the material from its molecular structure, and then select whether the material is suitable. ”
On the podium, Xu Chuan was slightly stunned after hearing the question. He did not expect that the first person to stand up and ask a question was a researcher in the field of materials.
Smiling, he replied: "Yes. This is a mathematical model I built for chemical materials. It can help me screen suitable materials and save some unnecessary time."
Hearing this, the researcher quickly asked excitedly: "Can you please introduce this?"
Xu Chuan thought for a while and said: "As a scholar in the field of materials, you should know very well that each different material has different chemical and physical properties."
"The so-called chemical reaction is actually the blending of molecules, finding order in disorder, and finding stability and replacement in complexity."
After a pause, he then changed the topic and said: "In fact, in my personal opinion, the development of chemistry today is not perfect."
"Because many times we cannot explain even the simplest chemical reactions theoretically. Can you use theory to explain why chemical reactions such as ionic reactions, non-ionic reactions, condensation polymerization reactions, and addition polymerization reactions occur?"
When asked by Xu Chuan, the researcher who asked the question was stunned for a moment and replied doubtfully: "Because of the ionization and recombination of matter?"
Xu Chuan smiled and said: "Strictly speaking, this is actually using physics to explain chemistry."
"Today's chemistry actually does not have a set of theories that can adapt to almost all chemical reactions."
"Of course, you can also say that the essence of a chemical reaction is the flow of electron clouds, but in fact it is still physics."
"But today we are not discussing the nature and explanation of chemistry. We can talk about this later. What we are talking about now is the mathematical model I use."
"It is based on using the three major theories of chemistry, physics, and mathematics to conduct data simulation of the entire chemical process."
"By collecting the different chemical and physical properties of each material in advance, integrating them into the model, and then using mathematics to simulate and calculate the reaction process."
"For example, the most common chemical reaction rates can be described by calculus equations. And mathematical equations can be solved using numerical methods to determine reaction rate constants and other parameters."
"Theoretically, if you know the information and conditions related to the materials that need to undergo chemical reactions, you can completely simulate the entire reaction process through mathematics."
"And that mathematical model is based on this. Do you understand?"
In the audience, after listening to Xu Chuan's explanation, researcher Evans Jerry's pupils shrank sharply and his breathing became extremely heavy. He seemed to understand why the other party had solved the problem of lithium dendrites in just a few months.
If such a model is really built, then the entire chemistry world, no, the entire materials world will change!
This change in the lithium battery industry is nothing more than an insignificant wave in front of this model.
