Li Jian did not expect that Director Tan would be so impressed by this paper on lithium batteries. He did not dare to neglect, and quickly notified the professors above the associate senior level of the Department of Materials and Chemistry to hold a meeting in the conference room of the department.
The Department of Materials and Chemistry of Jiangzhou University is a key department of Jiangzhou University. It also receives a lot of funding from the country every year and undertakes many key scientific research tasks of the country.
For example, anti-corrosion materials for a large ship, and consumable parts for a certain mechanical equipment field, etc.
Therefore, the professors with associate senior titles in the Department of Materials and Chemistry are basically experts in the industry.
If this era is set ten or twenty years later, these professors will start with an annual salary of one million when they go to any excellent company.
Soon, except for a few professors who were teaching, most of the professors from the Department of Materials and Chemistry came.
Li Jian also returned to the office and said, "Gao Miao, come here quickly."
Gao Miao was a little confused, but followed Li Jian to the conference room.
Originally, there was no one called Luo Hao, but Luo Hao has a thick skin, he must stay away from bad things, and he will definitely not miss any good things.
In the conference room, teachers and professors are basically all here.
Tan Deming put the thesis written by Gao Miao on the table, and he said to everyone: "I'm really sorry to waste your precious time, but we have important things to discuss today, I hope everyone will be calm and sit down patiently .¡±
Tan Deming saw Gao Miao and asked Li Jian: "Is this the student who wrote the thesis?"
Speaking of his favorite disciple, Li Jian was very proud, and quickly introduced him: "It's the Gao Miao I mentioned to you before, a very down-to-earth girl, talented and intelligent, and serious in her work."
Tan Deming nodded in satisfaction, looked at Luo Hao again, and asked unexpectedly: "Luo Hao is also in this experimental group?"
Because of Luo Hao's father, many people in the Material and Chemistry Department know Luo Hao.
Before Li Jian could speak, Luo Hao kept nodding, which meant that I was also in the experimental group, doing experiments and writing papers, and he also contributed.
Tan Deming said: "Please sit down first."
Everyone took their seats one after another, but Gao Miao was still a little nervous.
She didn't expect that this paper would attract the attention of the department leaders, and she was a little embarrassed.
Tan Deming said: "I invite everyone to come today to read a paper. This paper is the graduation thesis of our third-year graduate students. It is about some explorations of lithium battery materials and packaging technology. I think many experimental results and inferences in the paper are very important. The advanced ones can even reach the international advanced level, and everyone can pass them on to each other."
The professors began whispering and discussing, and then looked at the paper.
The more I read, the more I feel incredible, and the more I read, the more I feel that this paper is very good.
First of all, the structure of experiments and papers is very reasonable.
The steps and procedures of the experiment, as well as the use of the control group, are perfect, and they are done in full accordance with the experimental process repeatedly emphasized by the teacher.
With such a regular experimental process, even some younger teachers may not be able to fully implement it.
Looking at the content of the paper again, as Han Deming said, many conclusions and speculations are very advanced!
Moreover, it has filled many technical gaps in the country. What kind of graduate thesis is this? This is a complete and very beautiful scientific research innovation paper.
Immediately afterwards, everyone began to discuss these papers.
"Have lithium cobalt oxide batteries and ternary batteries been made yet?"
"I see that there are already experimental results written in the paper, and there are experimental products!"
"Such an energy density! Is it at the same level as Toyo's battery! Impossible!!"
The professors were all in a state of shock.
? They have no way to believe that the students of the school's third-party research institute can produce batteries with the same performance as Toyo's advanced enterprises.
"Look at the deduction at the back of the paper. I won't talk about polymer nano-diaphragms, but what are two-dimensional carbon molecules?"
"Is this about graphene?"
"Graphene has been proven scientifically to be non-existent. Is there some point in the paper that mentions this"
The professors began to discuss the final inference of the paper.
"If the description related to graphene is deleted, then the paper will be absolutely perfect!"
"Professor Li, I disagree with you."
"Although the carbon molecule of the two-dimensional crystal has not been discovered so far, nor has it been artificially synthesized, it cannot be proved that it does not exist!"
"I said prove, not think!"
The rest of the thesis is perfect without any flaws.
It is the problem of two-dimensional molecules as negative electrodes, which makes the professors have some doubts.
After all, two-dimensional carbon molecules are currently considered non-existent, and have not been found in laboratories or in nature (only graphite does not have graphene).
Its existence alone is just a guess in human experiments, and the probability of this guess being proved is very low.
Because there are many laboratories all over the world, after various experiments, it is found that thermodynamic fluctuations do not allow any two-dimensional crystals to exist at a finite temperature, which proves that graphene does not exist.
If graphene exists, according to the deduction of American experts, single-layer graphene has a light transmittance as high as 97.7%, which makes it completely transparent to the naked eye. Graphene also has a thermal conductivity as high as 5300w/m¡¤k , The room temperature above the carbon nanotubes is as high as 15000cm^2/v¡¤s carrier mobility, while the resistivity is as low as 10^-6¦¸¡¤cm, and copper and silver, the best metals, are even lower.
Once it is proved that graphene exists, it will be the material with the smallest resistivity in the world.
The professors of the Department of Materials and Chemistry of Jiangzhou University accepted some arguments from the West, and only then did they think that the two-dimensional structure of carbon molecule graphene does not exist.
Tan Deming clapped his hands and stood up and said: "Okay, everyone be quiet, let's not discuss the issue of graphene, let's talk about the paper itself, how do you feel?"
Deputy director Chen Gang stood up and said: "This should be the highest quality paper I have read in the past few years. This is not only a graduation thesis, but also an innovative paper on scientific research and innovation in the field of materials. Now I hope to see the progress of the battery. The real thing! If it is really successful, I think it can change the entire lithium battery industry."
Professor Tao, who has been teaching at Jiangzhou University for more than 20 years, also said: "The quality of the experiments and papers are very high, and they are very operable, and can even become industry norms! I suggest that this paper be reported to the school leaders. See if you can ask the superior department for some funds, so that the papers and experiments can be implemented in the industry!"
Han Deming nodded with a smile, this was also his idea.
Han Deming looked at Gao Miao and said: "Student Gao Miao is the team leader and main writer of this experiment. How about your idea and process of the experiment?"
Everyone was even more surprised when they saw that the author of the previous paper turned out to be a girl.
Before Gao Miao started to speak, Professor Tao said again: "You are Gao Miao? Personally, I suggest that for the sake of the perfection of your paper, you should delete the speculation about graphene as the negative electrode material in the last paragraph."
