Rebirth 1999: Opening the Age of Black Technology

Li Jian did not expect that this paper on lithium batteries would make Director Tan so fancy. He did not dare to neglect, and quickly notified the professors above the deputy 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 funds from the state every year and undertakes many key scientific research tasks of the country.

For example, anti-corrosion materials for a large ship, and consumable parts in the field of machinery and equipment, etc.

Therefore, the professors with deputy senior titles in the Department of Materials and Chemical Engineering are basically experts in the industry.

If you put this era in ten or twenty years, these professors will start with an annual salary of one million when they go to any excellent company.

Soon, with the exception of very few professors in class, most of the professors in the Department of Materials Science and Engineering came.

Li Jian also returned to the office and said, "Gao Miao, come here quickly."

Gao Miao was a little stunned, but still followed Li Jian to the conference room.

Originally, it was not called Luo Hao, but Luo Hao has a very thick skin. He must hide away from bad things, and he must not let any good things fall.

In the conference room, teachers and professors are basically all present.

Tan Deming put the paper written by Gao Miao on the table, and he said to everyone: "I'm really sorry to waste everyone's precious time, but today we have important things to discuss. I hope everyone will stay calm and sit patiently. ."

Tan Deming saw Gao Miao and asked Li Jian, "This student wrote the thesis?"

Speaking of his proud disciple, Li Jian was very proud, and quickly introduced: "It's the Gao Miao I mentioned to you before, a very down-to-earth girl, talented and smart, and serious in doing things."

Tan Deming nodded with 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 science department know Luo Hao.

Before Li Jian spoke, Luo Hao kept nodding his head, 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, and Gao Miao was still a little nervous.

She didn't expect that this paper actually attracted the attention of the department leaders, and she was a little embarrassed.

Tan Deming said: "I invite everyone to come here today to see a paper. This paper is the graduation thesis of our third-year students. About some explorations of lithium battery materials and packaging technology, I think many experimental results and inferences in the paper are very important. If it is advanced, it can even reach the international advanced level, and everyone can pass it on to each other.”

The professors started whispering and discussing, then looked at the paper.

The more I read it, the more incredible it is, and the more I feel that this paper is very high-level.

The first is that the experiments and papers are very well structured.

The steps and procedures of the experiment, as well as the use of the control group, are all perfect, and they are done in full accordance with the experimental procedure repeatedly emphasized by the teacher.

Such a regular experimental process, even some young teachers, may not be able to do it completely.

Looking at the content of the paper, as Han Deming said, many conclusions and speculations are very advanced!

Moreover, it has filled many technical gaps in China. What is the graduate's thesis? 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?"

"I see that there are already experimental results written on the paper, and there are experimental products!"

"Such an energy density! Is it about the same level as Toyo's batteries! It's unlikely!"

The professors were in a state of shock.

They have no way to believe that the students of the school's third grade can produce batteries with the same performance as Toyo's advanced companies.

"Look at the inferences at the back of the paper, we won't talk about the polymer nanomembrane, but what are two-dimensional carbon molecules?"

"Does this mean graphene?"

"Graphene has been scientifically proven to be non-existent, is there something in the paper that mentions this..."

The professors started a discussion about the final corollary of the paper.

"If the graphene-related descriptions were deleted, the paper would have been absolutely perfect!"

"Professor Li, I don't agree with you."

"Although the carbon molecule of the two-dimensional crystal has not been discovered or synthesized so far, it cannot be proved that it does not exist!"

"I'm talking about proving, not thinking!"

The rest of the paper 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 the laboratory or in nature (only graphite and no graphene).

Its existence alone is just a guess by humans in 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, thus proving that graphene does not exist.

If graphene exists, according to the inference of American experts, single-layer graphene has a transmittance of up to 97.7%, which makes it completely transparent to the naked eye, and graphene also has a thermal conductivity of up to 5300W/m·k , the carrier mobility at room temperature is as high as 15000cm^2/V·s above the carbon nanotubes, while the resistivity is as low as 10^-6Ω·cm, and copper and silver, the leaders of metals, are even lower.

Once graphene is proven to exist, it will be the material with the lowest resistivity in the world.

The professor of the Department of Materials Chemistry of Jiangzhou University accepted some Western arguments, which led to the belief that two-dimensional carbon molecular graphene does not exist.

Tan Deming clapped his hands and stood up and said, "Okay, everyone please be quiet, let's not discuss the graphene issue first, 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. I now hope to see the battery In kind! If it is really successful, I think it can change the entire lithium battery industry."

Professor Tao, who has taught 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 an industry norm! I suggest that this paper be reported to the school leaders, see See if you can ask the higher-level department for some funds so that the papers and experiments can be implemented in the industry!"

Han Deming smiled and nodded constantly, which 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. Can you tell us about your experimental ideas and process?"

Everyone was even more surprised to see that the author of the previous paper was actually a girl.

Before Gao Miao began to speak, Professor Tao said, "You are Gao Miao? I personally suggest that, for the sake of the perfection of your paper, delete the speculation that graphene is used as a negative electrode material in the last paragraph."
