Chapter 501： Continue to cooperate (on)

The simplest parallel plate capacitor, the capacitance is proportional to the positive area of ​​the two plates, the larger the area, the larger the capacitance. It is inversely proportional to the distance between the two plates. The smaller the distance, the larger the capacitance. Of course, the smaller the distance, the smaller the breakdown voltage may be, so a special insulating medium is needed instead of air as the dielectric between the capacitor sheets.

Professor Ma experimented with a variety of materials and finally found a medium. The electrode thickness is 1 micron, and the doped modified barium titanate nanoparticles are used as the dielectric. The dielectric constant of the dielectric can be made to 19861, the withstand voltage can be 557v/micron, the thickness is 10 micrometers, and the specific energy density. Up to 402 wh / kg, which is ten times the specific energy density of lead-acid batteries, but the weight and volume are only one-tenth of the lead-acid batteries. This data is about four times the average specific energy density of lithium batteries.

If you can do it thinner, maybe this number can be improved. But so far, the processing level of the school laboratory has reached the limit, this barium titanate medium can not be made thinner. Therefore, I have to resort to Guo Tailai. "

machining? no problem! Guo Tailai immediately came to the interest: "Materials to me, what area and thickness do I need to process?" Put the request forward! ”

If anything else, Guo Tailai may not really help, but if it is only processed, Guo Tailai is completely out of the question. As long as he asks, Guo Tailai will do his best.

Material processing is indeed very difficult, but in the experimental phase, you can only use this stupid way. After finding the right materials, we will try our best to conduct industrial production research and reduce costs through mass production. Basically all the transformation of scientific research results is this routine, there is no shortcut.

"If the selected dielectric material is suitable, you can work with the chemical department to find a suitable production method." Guo Tailai reminded.

In fact, this is a nonsense. Can Professor Ma still know this truth?

With good materials and processing requirements, Guo Tailai will bring it to the company to process. When he left, Guo Tailai suddenly remembered a question and asked Professor Ma, "Mr. Ma, is this dielectric material as thin as possible?"

In the case where the breakdown voltage is constant, of course, the thinner the better. Teacher Ma replied with a smile: "This is high school physics knowledge! You won't forget it? ""

That, suddenly there is an idea. Guo Tailai smiled embarrassedly; "Go, go find the teacher Han." ”

Seeing that Guo Tailai and Professor Ma came together to find themselves, the academician Han was somewhat surprised. Is this something?

"This is the case, Teacher Han." Guo Tailai quickly introduced the situation here, and then asked the Korean academician: "Double-layer graphene will exhibit superconductivity at a certain angle, then Is there still a possibility that it will exhibit an insulator state at some angle?"

The academician directly stopped and carefully began to ponder. After a while, some unconfirmed said: "There is such a possibility, but it still needs to be confirmed by experiments."

Tailai is also happy. Since there is such a possibility, investment will continue to study. When turning to Professor Ma again, Guo Tailai did not hide his happiness: "Mr. Ma, double-layered graphene, two layers of carbon atoms, should there be no material thinner than this?"

Not anymore! Although the same is the Department of Physics, Professor Ma and Dr. Han have not studied this in tandem. One is graphene and the other is supercapacitor. I have never thought of an intersection! But now Guo Tailai thinks in such a mind. The possibility of linking the two people’s research.

Academician Han came out here, and Professor Ma was also a sigh. No wonder they are willing to chat with Guo Tailai or study together. His unconventional imagination is the most popular among these academic leaders! "

Xiao Guo, this supercapacitor, even if you can find the right medium in the short term, you have to consider the market prospects. "Professor Ma, they are the people who are least willing to lose money to Guo Tailai, so some words are also true: "Before developing a method to control uniform discharge, I am afraid that the application prospects are not very big, you may have psychological preparations!" ""

A good thing to charge and discharge so fast. "Guo Tailai's eyes are too fast to find: "Electromagnetic guns are also good, electromagnetic ejection is also good, they worry that the discharge speed is not fast enough! ""

Uh! Professor Ma glanced, and then smiled and laughed at himself: "Yes, I just said that I didn't say it. I am doing research to be stupid, hahahaha!" ”

Suddenly I found the market I studied, and Professor Ma immediately became happy. This way, you don't have to worry about Guo Tailai's investment loss. You can rest assured that the research has gone on.

Back at the company, Guo Tailai plunged into his own dedicated processing studio and began processing these barium titanate dielectrics according to Professor Ma's requirements. plus

The requirements are very simple. In fact, the thickness is decremented in microns, 9 microns, 8 microns... up to 1 micron, and then tested separately. The difficulty of processing is that the thickness should be extremely uniform and the error should not be too large. Even Guo Tailai must be careful to use a very fine plate composed of nano-robots to ensure that the thickness does not change much. horse

The professor only asked for a thickness of one micron, but after Guo Tailai pondered it, he looked at the material enough, and made nine hundred nanometer-scale thicknesses in units of 100 nanometers, and then decremented by 10 nanometers. At 90 nanometers, it has been 10 nanometers. A total of twenty-seven different kinds of dielectric samples were made and carefully fixed. This is a relief.

In fact, the thickness of 10 nm and 20 nm is slightly higher than the processing error, and the accuracy is not particularly high, but it can be used for reference. Light

It was the processing of these extremely thin dielectrics. Guo Tailai spent a whole day and didn't go home at night and worked day and night in the company. Ann

The reliable man handed these processed products to Professor Ma, and Guo Tailai was relieved by himself. He left the restaurant in the vicinity of the place where he lived with Chu Fei and ordered a large table dish. When several security guards were comfortable, Colonel Liu’s phone came over.

“The leaders made a decision after research.” Colonel Liu’s tone showed a lightheartedness: “They are willing to name you, but they cannot accept your gift.”

what? Guo Tailai did not expect this result, a bit disappointed."

But the leader also said that if you can continue to cooperate with domestic automakers to launch new models, they are willing to make this advertising spokesperson for you. Colonel Liu certainly knows why Guo Tailai was disappointed, and then smiled and said: "Your car is an advertising fee." ""

no problem! "After listening to this, Guo Tailai immediately got up in spirit: "I will go back to Gusu to build a car. ”
