Chapter 287 The Huge Change in Lithium Batteries Is Just a Small Storm!
PS: I can’t write the title any more, (7/10 extra chapters for the leader, Gao Shan Liu Shui. The extra chapters for the leader are finally almost finished. I’ll finish them in the next few days. There are other extra chapters for the rest. I’ll return them after this one is finished.)
As May 30 approaches, the ancient city of Jinling once again welcomes flights from all over the world.
The press conference of the Sichuan Ocean Materials Research Institute is about to begin. Major battery manufacturers, research institutes, and even mobile phone manufacturers and automobile manufacturers have come to join in the fun.
With so many people participating, the venue originally prepared by Xu Chuan is no longer enough, so he borrowed a lecture hall from Nanjing University.
On May 30, the day of the press conference, the lecture hall was crowded and full.
Many representatives of manufacturers came to 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 wanted to see if they could squat with Xu Chuan.
If you can leave a good impression in front of this young big shot in advance, the probability of obtaining the patent authorization for artificial SEI film will naturally be greater.
Of course, it’s not just these manufacturer representatives who are present.
In addition to them, many researchers in the field of materials also came over. Although the Sichuan Institute of Materials Research did not send them an invitation letter at the beginning, these people still came over on their own initiative.
These scholars in the field of materials research are not concerned about who will get the patent authorization of artificial SEI film in the end, but what they care about is what is shown in the paper.
A mathematical model established for chemical material research and development!
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 incompatible and adaptive materials in the research and development process.
Although it is normal to use mathematical models to assist in material research and development.
But the paper posted on Arxiv shows something completely different.
Unlike the mathematical model used in the material research and development, it seems to be reprocessed from the atomic and molecular level of the material and the performance of the material.
Some researchers quickly realized that this might be something new, and that Professor Xu Chuan was able to find the key to solving the lithium dendrite problem within a few months, which is likely to be in this mathematical model.
Therefore, almost all the scholars who noticed this detail called the Sichuan Institute of Materials and asked for an invitation letter.
At 10 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 quieted down, and eyes were watching him warmly and expectantly.
Xu Chuan walked up to the lecture platform as usual and looked at the crowd below.
After trying the microphone, he spoke clearly: "First of all, welcome everyone to come here from afar to attend today's press conference."
"The theme of today's lecture is the press conference of artificial SEI film products."
While speaking, Xu Chuan opened the PPT copy prepared in advance.
"I believe that everyone who is here today has a certain understanding of the lithium dendrite problem, so I am not going to talk about those superficial theories."
"As for the paper I published on 'carboxymethyl cellulose-lithium fluorocarbon compound materials' to guide lithium ion deposition in lithium batteries and solve the problem of lithium dendrite formation, I believe that everyone has learned about it before coming here, and even most laboratories should have repeated the relevant experiments and obtained the data they want."
"So, although my paper has not been published in a professional journal for the time being, everyone knows that it is correct and has successfully solved the lithium dendrite problem."
"What I am going to talk about next is, on the one hand, the performance of this artificial SEI film. On the other hand, after the lithium dendrite problem is solved, the lithium battery industry has a broad prospect."
"OK, let's get to the point."
". The artificial SEI film reorganized and manufactured by nanotechnology can effectively inhibit the generation of lithium dendrite protonuclei and guide lithium ions to deposit in an orderly manner on one side of the film."
On the podium, Xu Chuan talked freely.
In fact, whether it is talking about how excellent the performance of artificial SEI film is or how broad the prospects of the lithium battery industry are, it is just to sell his patent at a good price.
If not, why would he waste his time on such a press conference?
". After solving the problem of lithium dendrites, the battery capacity of lithium batteries on the market today can be increased by several orders of magnitude. Not to mention, just replacing the negative electrode material from the current graphite to lithium metal is enough to increase the battery capacity several times."
"Think about it, when the battery capacity is increased several times, what changes will happen to our world? Mobile phones will last more than a week! Electric vehicles will double their mileage."
On the stage, Xu Chuan gave a passionate speech.
Under the stage, countless audiences had lights in their eyes.
In fact, those who can sit here today, apart from those scientific researchers, others don't need Xu Chuan to say what changes the increase in lithium battery capacity will bring.
What's important is not the report meeting, but the auction of artificial SEI film patent authorization after the report meeting!
Without wasting too much time on the press conference, Xu Chuan began to wrap up in less than half an hour.
"Today's press conference ends here."
"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 using theory. 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."
"In today's chemistry, there is actually no 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 mathematically simulating 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 a small wave in front of this model.
