Material Empire: Start Cans For Airplanes

Yoshino Taiji didn't expect that he would be cornered as soon as he came up.

No matter how straightforward a scientist is, he is not stupid enough to tell the truth.

During the time interrupted by the host, he finally came up with a good wording: "Science knows no borders! The purpose of my visit to Mr. Su is just to exchange ideas about the research field of lithium-ion batteries."

"Countless examples show that in the process of communication, scientists will collide with sparks of thought, which may make a certain technology go on the fast track."

"At present, in the field of lithium-ion batteries, only Sony and Weihua have achieved commercialization, so it is necessary to communicate.

The nonsense that "science knows no borders" has deceived a lot.

In Su Hao's cognition, all those who request academic exchanges under this guise, without exception, are the ones with relatively weak scientific research capabilities.

The purpose of communication is self-evident.

"Great!"

Su Hao clapped his hands together and asked with a smile: "As far as I know, Dr. Yoshino has amazing achievements in the field of carbon fiber research. Could you please explain the temperature requirements for the preparation of polyacrylonitrile raw silk?"

In the field of carbon fiber, Dongying's research and development technology has been at the forefront of the world.

The lithium-ion battery anode material developed by Yoshino is a carbon fiber material with a tensile strength of up to 7Gpa.

It is expensive and can only be mass-produced on a small scale.

The stealth fighter F22 uses a large amount of carbon fiber produced from polyacrylonitrile raw silk, which makes the fuselage strong to a terrible level.

It can be compared with the metal strength of titanium alloy.

It is also a product and technology strictly embargoed by Western powers against China, and it is a good thing that cannot be bought with money.

"Uh.………"

Taiji Yoshino was helpless: "Mr. Su, polyacrylonitrile precursor is the basic raw material of high-strength carbon fiber, which belongs to our country's scientific and technological secrets. I have nothing to say about it."

"You are the one who said science has no borders, and you are the one who said science and technology are confidential. So, what are you here to communicate?"

When the old devil looked embarrassed and didn't know what to do, Su Hao spread his hands together: "Dr. Yoshino, my problem is only the temperature control of the polyacrylonitrile raw silk during the production process, and it's not about your core patent~々 .

In the field of material research, temperature control is the core key point.

If the production control temperature is clearly known, the corresponding materials can be prepared by different methods.

This is a general direction.

As long as you find the general direction, it is only a matter of time and investment to get the correct result. You can always find the right way by trying several processes and formulas.

Therefore, temperature control is a core secret that is not part of the patent registration content.

Any material giant must keep silent.

Directly asking the other party's core secrets is to let the old devil slap his own mouth and swallow the phrase "science knows no borders".

Use the program to tell domestic scientists: Stop dreaming, the core content of academic exchange meetings held by various names is to steal core secrets.

Don't get an invitation and get so excited that you forget your last name.

Don't be silly and show off your core secrets in public in exchange for a bunch of worthless certificates and thank you letters.

Before contributing to the progress of human civilization, the most important thing is to transform research results in professional fields into national strength.

These words, as a junior, are not suitable for speaking to seniors.

Suspected of pointing fingers.

Drowsiness meets the pillow.

The old devil Yoshino had no good intentions, and came here to make some academic exchange, so let's exchange and see who suffers.

"Mr. Su is a bit difficult!" Taiji Yoshino summoned up his courage and said with a straight chest: "Science has no borders, but scientists have borders!"

"The carbon fiber production process is a highly confidential technology of Dongying. Countless people rely on this industry to support their families."

"If it is leaked, I will be a sinner of the country."

The old man's face burned a little bit.

Slap in the face!

Just said "science has no borders" and then threw out reasons such as "scientists have treasure springs" and refused to answer the question.

For the following communication content, which standard should we refer to?

Su Hao shook his head and smiled: "Dr. Yoshino, don't worry, I won't make you a criminal of the country, and I won't ask about the production process of carbon fiber. The question is, what do you want to exchange when you come to me?"

Small!

Ask about your leading technical content, which is a state secret, and the answer you get can only be no comment.

Then when you ask me, don't blame me for having no comment either.

Taiji Yoshino breathed a sigh of relief, and said with a grin: "Mr. Su completed all the courses from high school to university in only four years, and then discovered and mastered the preparation technology of graphene. It's really amazing."

After praising him with two thumbs up, he slowly asked the question: "My question is, how did Mr. Su think of using the vapor deposition method to prepare graphene nano-film materials on a large scale?"

Cheating?

The small-scale graphene film material production workshop invested by Weihua Holding Group did not disclose the production process used to prepare it.

The monkey-spirited old devil asked two answers to a seemingly light question in a disguised form.

Su Hao is not fooled: "`||This is the secret teaching method of our University of Science and Technology."

"Mr. Yoshino also said just now that science has no country, but scientists have national boundaries."

"In order to maintain the leading edge of our country and schools in the field of education, it is inconvenient to explain too much to you.

"Moreover, in the field of lithium-ion battery research, our second-generation product is about to be put into construction, and the research and development of the third-generation product has reached the middle stage.

"In this field, there is a ten-year technological gap between your country and your company, and there is nothing to communicate with us."

Xiao Ye knows the core technology of each generation of lithium-ion battery development.

Say it and scare you to death!

When it was time to pretend, Su Hao didn't let it go.

"Your company's second-generation lithium-ion battery is already going into commercial production (Zhao's Zhao)?" Taiji Yoshino opened his mouth in disbelief.

It was as if he had heard the news that God was about to appear.

The first-generation lithium-ion battery produced by Weihua Holding Group has doubled the energy density of Sony's lithium-ion battery.

So, how far will the second-generation products throw their own products?

Su Hao didn't seem to see the other party's surprise, and explained with his fingers boredly: "The first generation of lithium-ion batteries is supplied to mobile phone batteries, and the production capacity needs to be expanded to meet the growing consumer demand."

"It is estimated that the annual sales will reach 80 billion yuan and it will be over."

"The supply direction of the second-generation lithium-ion batteries is for notebook computers."

"We've made a laptop-specific battery that weighs only 300 grams and can store 56 watts of power.

Hearing Su Hao's explanation, Yoshino Taiji suddenly stood up like crazy, and screamed: "Impossible Ku!".
