The simplest parallel plate capacitor has a capacitance proportional to the area opposite to 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 to serve as the dielectric between the capacitor plates.

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

If it can be thinner, perhaps this number can be improved. But so far, the processing level of the school laboratory has reached its limit, and this barium titanate medium can no longer be thinner. Therefore, I have to turn to Guo Tailai."

Processing? No problem!" Guo Tailai immediately became interested: "Give me the material, what area and thickness do I need to process? Make the requirements!"

If it were anything else, Guo Tailai might not be able to help, but if it was just processing, Guo Tailai was no problem at all. As long as he made a request, Guo Tailai would do his best to do it.

Material processing is indeed very difficult, but in the experimental stage, you can only use this stupid method. After finding the right materials, you will try every means to conduct industrial production research and reduce costs through large-scale production. Basically, all scientific research results are converted into this routine, and there are no shortcuts.

"If the dielectric material you choose is suitable, you can cooperate with the chemistry department to find a suitable production method." Guo Tailai reminded.

Actually, this is nonsense. How can Professor Ma not know this truth?

With the materials and processing requirements, Guo Tailai wanted to take them to the company for processing. When he left, Guo Tailai suddenly remembered a question and asked Professor Ma: "Teacher Ma, is this dielectric material thinner the better?"

When 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 all, right?"

That, suddenly I had an idea." Guo Tailai smiled embarrassedly; "Let's go and ask Teacher Han together."

Academician Han was a little surprised when he saw Guo Tailai and Professor Ma come to find him together. Is there anything wrong?

"That's the case, Teacher Han." Guo Tailai quickly briefly introduced the situation here, and then asked Academician Han: "Double-layer graphene will show superconducting characteristics at a certain angle. Is there another possibility that it will show an insulator state at a certain angle?"

The academician was stunned and began to think about it carefully. After a while, he said with some uncertainty: "This possibility exists, but it still needs to be proved by experiments." Guo

Tailai was also happy. Since there was such a possibility, then invest and continue research. When he turned to Professor Ma's side again, Guo Tailai did not hide his happiness: "Teacher Ma, two-layer graphene and two-layer carbon atoms, there should be no material that is thinner than this, right?"

No!" Although they are from the Department of Physics, Professor Ma and Academician Han have not yet studied it in series. One is graphene and the other is supercapacitor. I never thought there would be intersections! But now Guo Tailai's thinking about the possibility in his mind has linked the research of the two people.

When Academician Han came out here, Professor Ma also sighed. No wonder he was willing to chat with Guo Tailai or study together. His unconventional imagination is what these academic masters like the most!”

Xiao Guo, even if you can find a suitable medium to make this super capacitor in the short term, you have to consider the market prospects." Professor Ma and others are the people who are the least willing to lose money in Guo Tailai, so some of them are honest: "Before developing a method to control uniform discharge, the application prospects are probably not very big, you have to be mentally prepared!"

A good thing that charges and discharges so quickly." Guo Tailai's eyes were so narrowed that he could hardly find it: "Whether it is an electromagnetic cannon or an electromagnetic catapult, they are worried about the discharge speed not being fast enough!"

Uh!" Professor Ma was stunned, then smiled bitterly and started to laugh at himself: "Okay, I didn't say what I said just now. I'm stupid in doing research, hahahaha!"

Suddenly, he found the market he studied, and Professor Ma immediately became happy. In this way, there is no need to worry that Guo Tailai's investment will lose money, and he can continue to study with confidence.

After returning to the company, Guo Tailai plunged into his own special processing studio and began to process these barium titanate dielectrics according to Professor Ma's requirements.

The processing requirements are very simple. In fact, the thickness is reduced in units of microns, 9 microns, 8 microns... until 1 micron, and then the tests and tests are carried out separately. The difficulty of processing lies in the fact that the thickness must be extremely uniform and the error cannot be too large. Even Guo Tailai has to carefully use extremely fine plates composed of nanorobots to ensure that the thickness does not change much.

The professor only asked to achieve a thickness of one micron, but after Guo Tailai thought about it, he saw that the material was enough, and then reduced nine hundred-nanometer-level thicknesses according to 100 nanometers. By decreasing from 90 nanometers, he continued to achieve 10 nanometers, and made a total of twenty-seven dielectric samples of different specifications, carefully fixed them, and then he breathed a sigh of relief.

In fact, the thickness of 10 nanometers and 20 nanometers is slightly close to the processing error, so the accuracy is no longer particularly high, but it can still be used for reference for the time being.

It was to process these extremely thin dielectrics, so Guo Tailai spent more than a whole day and didn't go home at night and stayed up late to work in the company.

The reliable person brought the finished products to Professor Ma's side. Guo Tailai was relieved and left the Hunan restaurant near the company where he lived, where he often ate with Chu Fei. When he was having a good time with a few security guards, Colonel Liu called.

"The leaders made a decision after research." Colonel Liu's tone showed a sense of ease: "They are willing to justify you, but they cannot accept your gift."

Ah?" Guo Tailai didn't expect this to be the result, and he was a little disappointed."

But the leader also said that if you can continue to cooperate with domestic auto factories to launch new models, they are willing to be the advertising spokesperson for you." Colonel Liu of course knew why Guo Tailai was disappointed, and then smiled and said, "Your car is just regarded as advertising fees."
