Chapter 1002 Continue to Cooperate (Part 1)

The simplest parallel plate capacitor, the capacitance is proportional to the area of ​​the two plates, the larger the area, the greater 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 to replace air as the dielectric between the capacitor plates.

Professor Ma and the others experimented with a variety of materials, and finally found a medium. Make the thickness of the electrode 1 micron, use doped modified barium titanate nanoparticles as the dielectric, the dielectric constant of the dielectric can reach 19861, the withstand voltage can reach 557V/micron, the thickness can reach 10 microns, and the specific energy density Up to 402WH/kg, which is ten times the specific energy density of lead-acid batteries, but only one-tenth of the weight and volume of lead-acid batteries. This data is about four times the average specific energy density of current lithium batteries.

If it can be made thinner, perhaps this number can be increased. But so far, the processing level of the school laboratory has reached its limit, and this barium titanate dielectric can no longer be made thinner. Therefore, I had to turn to Guo Tailai for help.

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

If it's anything else, Guo Tailai might not be able to help, but if it's just processing, Guo Tailai is not a problem at all, as long as there is a request, Guo Tailai will do it with all his heart.

Material processing is indeed very difficult, but in the experimental stage, this kind of stupid method can only be used. After finding a suitable material, we will try our best to conduct research on industrial production and reduce costs through mass production. Basically, all the transformation of scientific research results follows this routine, and there is no shortcut.

"If the selected dielectric material is suitable, we can cooperate with the Department of Chemistry to find a suitable production method." Guo Tailai reminded.

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

Bring the materials and processing requirements, and Guo Tailai will take them to the company for processing. When leaving, Guo Tailai suddenly thought of a question, and asked Professor Ma: "Mr. Ma, should the thinner the dielectric material be, the better?"

"Under the condition that the breakdown voltage is constant, of course the thinner the better." Teacher Ma replied with a smile: "This is high school physics knowledge! Don't you forget it?"

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

Seeing Guo Tailai and Professor Ma coming to him together, Academician Han was a little surprised. What's the matter?

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

Academician Han was stunned, and began to ponder carefully. After a while, he said with some uncertainty: "There is such a possibility, but it needs to be confirmed by experiments."

Guo Tailai also became happy, since there is such a possibility, then invest in and continue researching. When he turned to Professor Ma again, Guo Tailai did not hide his happiness: "Mr. Ma, double-layer graphene, two-layer carbon atoms, there shouldn't be any material thinner than this?"

"No more!" Although they are both from the Department of Physics, Professor Ma and Academician Han have never been connected in series for research. One is graphene and the other is supercapacitor. I never thought there would be an intersection! But now that Guo Tailai has such a possibility in his mind, he has connected the research of the two people.

Coming out of Academician Han, Professor Ma sighed for a while. No wonder everyone is willing to chat with Guo Tailai or study together. His eclectic and unrestrained imagination is what these academic leaders love to see the most!

"Xiao Guo, even if you can find a suitable medium to manufacture this supercapacitor in a short period of time, you still have to consider the market prospect." Professor Ma and the others are the ones who are least willing for Guo Tai to lose money, so some words are sincere: "Unless you develop a method to control the uniform discharge, I'm afraid the application prospect is not very great, you have to be mentally prepared!"

"It's a good thing that charges and discharges so fast." Guo Tailai almost couldn't find it because of his eyes.

"Uh!" Professor Ma was taken aback, and then laughed wryly at himself: "Well, I didn't say what I said just now, I was doing research and being stupid, hahahaha!"

Suddenly he found the market he was researching, and Professor Ma immediately became happy. In this way, there is no need to worry about Guo Tailai's investment loss, and he can continue to study boldly with confidence.

Back at the company, Guo Tailai plunged into his dedicated 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 microns, 9 microns, 8 microns... until 1 micron, and then tested separately. The difficulty of processing is that the thickness must be extremely uniform, and the error should not be too large. Even Guo Tailai had to carefully use extremely fine flat plates composed of nano-robots to ensure that the thickness does not change much.

Professor Ma only asked for a thickness of one micron, but Guo Tailai thought about it and found that the material was sufficient, so he made nine kinds of thicknesses of hundreds of nanometers in units of 100 nanometers, and then decreased in units of 10 nanometers, from 90 nanometers have been achieved to 10 nanometers, and a total of 27 dielectric samples of different specifications were made, and they were carefully fixed, and I was relieved.

In fact, the thickness of 10 nanometers and 20 nanometers is slightly close to the processing error, so the accuracy is not particularly high, but it can still be used as a reference for the time being.

It took Guo Tailai more than a whole day to process these extremely thin dielectric materials, and he didn't go home at night, staying up late at the company to work.

After arranging reliable personnel to send these finished products to Professor Ma, Guo Tailai himself was relieved, and left the company where he often ate at the Hunan restaurant near where he lived and ordered a large table of dishes. When the security guards were eating comfortably, Colonel Liu called.

"The leaders have made a decision after research." Colonel Liu's tone revealed a sense of relief: "They are willing to rectify your name, but they cannot accept your gift."

"Huh?" Guo Tailai didn't expect this result, and was a little disappointed.

"But the leader also said that if you can continue to cooperate with domestic automobile factories to launch new models, they are willing to be the spokesperson for this advertisement." Of course, Colonel Liu knew why Guo Tailai was disappointed, and then said with a smile: "Your car, Think of it as an advertising fee.”

"No problem!" Hearing this, Guo Tailai immediately cheered up: "I'll go back to Gusu to build a car right away."
