Scholar’s Advanced Technological System

After Arranging Wei Wen’s whereabouts, Lu Zhou turned back to the office and continued to prepare his PPT.

During this time, his work will basically be carried out around the “theoretical model of the interface structure of electric chemistry”.

Just a week later, when Lu Zhou finally completed his PPT, he suddenly received a call from Yang Xu.

As soon as the phone was connected, there was an excitement in the earpiece.

“We have succeeded! We have succeeded!”

Upon hearing the exhilarating tone, Lu Zhou sighed slightly and immediately asked: “Lithium-sulfur battery?”

Yang Xu holding the phone is nodded, and the tone is excitedly said: “Well! Your idea is right, we use glucose as the precursor, choose polyaniline? Polypyrrole copolymer as a pore former, successfully synthesized up to a specific surface area 3022m2/g, hollow carbon nanospheres with a diameter of only 69nm.”

Drinking a slobber, Yang Xurun, who is excited, said that he couldn’t wait to continue.

“Then, we mixed the hollow carbon spheres with the sulfur elemental material by chemistry deposition method, assembled it into the battery mold, and tested the performance of the battery pack. The final result is quite gratifying.”

“I don’t talk about the many things on the phone. I have sent the relevant experimental data to your mailbox. Let’s take a look!”

“Okay, I will go.”

Seeing Yang Xu’s expression so excited, Lu Zhou also came to the interest, then turned off the video call and immediately logged in.

In less than five minutes, he received an email from Yang Xu.

After downloading the attachments in the mail, Lu Zhou opened up the experimental data roughly organized into pdf format with a professional reader, and then read them one by one from the first part.

In this experimental data, not only battery performance test data, but also a photograph taken with a scanning electron microscope, and a curve drawn based on each data.

As Yang Xu said, the performance of this new material is quite good, and it is no wonder that his voice will be so excited.

Compared with the original hollow carbon nanospheres and activated carbon nanospheres prepared by activation of potassium hydroxide, the novel hollow carbon sphere and sulfur composites exhibit superiority under the condition that the sulfur content is 70%. Cycle performance.

This is the macro level, and the changes at the micro level are quite interesting.

The sulfur ions embedded in the hollow carbon spheres can normally escape from the surface pores of the hollow carbon spheres and electrochemically react with the lithium ions moving to the positive electrode, and the generated Li2S2 and Li2S are between the carbon spheres and the carbon spheres. The gap is quiet, avoiding the effect of the pore size blockage on the electrical chemistry cycle.

On the other hand, since the charged sulfur ions are in limited contact with the lithium ions moving to the positive electrode, the formation of the long-chain compound LiSn (n>2) is largely avoided.

It is well known that long-chain LiSn molecules that are easily soluble in organic solutions are the culprit of the Shuttle effect. If the formation of such products can be reduced from the formation mechanism, it is equivalent to preventing the loss of the positive electrode material from the source.

Not only that, even if LiSn(n>2) compounds are formed in the reaction system finitely, due to the surface adsorption of the hollow carbon spheres, the polysulfide compound is retained in a large amount in the skeleton of the positive electrode material. Instead of diffusing through the surface of the material into the electrolyte.

With these two layers of insurance, the effect of the shuttle effect has been reduced to a minimum.

Turning over this part of the analysis of physical and chemical properties, Lu Zhou directly looked towards the battery test part.

According to the experimental test of multiple sets of battery cells conducted by Nanjing Computational Materials Research, when the sulfur content is 73%, the ability to inhibit the diffusion of polysulfide compounds into the electrolyte reaches a peak. After the 500 cycle, the Coulomb efficiency remained at a fairly high level.

When the sulfur content is 75%, the comprehensive performance of the battery reaches the optimal level by comprehensive factors such as Coulomb efficiency, mass energy density, volume energy density and the like.

Regarding this new type of hollow carbon sphere material, Yang Xu named it HCS-2 material according to the naming principle previously established by Lu Zhou.

Compared with the HCS-1 material, which has relatively limited industrial application value, this new material is undoubtedly more likely to be industrially produced!

“It’s perfect.”

Putting the experimental report in his hand on the table, Lu Zhou felt a sigh in his heart, then took the phone out of his pocket and called the star technology CEO White Sheridan messer to let him immediately start international patents. Application.

Taking into account the broad prospects of this material in industrial applications, based on the research results, Star Technology will separately register patents on a series of aspects such as the compound, production, use and mixture ratio of HCS-2 materials. Establish a complete set of patent barriers.

If the situation is optimistic, he can get the patent number before the end of the month, and then he can start writing thesis.

As a model for solving real-world problems using computational materials methods, the success of HCS-2 materials will undoubtedly provide an important factual argument for his theoretical model of electrical chemistry interface structure.

Compared to this carbon-sulfur composite itself, Lu Zhou is particularly looking forward to this…

……

White’s work was very efficient, and Lu Zhou had not been able to go through it for a long time. All the documents submitted for patent application successfully passed the application.

After getting the patent number, he immediately began writing thesis.

The last thesis about HCS-1 was written by him. There are ready-made templates to apply. The writing of thesis didn’t cost Lu Zhou too much time. In less than three days, the whole thesis was fixed.

Taking into account a series with HCS-1, this time, he still chose “Science” as the target of submission, and sent the manuscript to the mailbox of the editorial department of Science.

After the completion of the draft, Lu Zhou did not take care of it and began preparing for the upcoming conference at the Max Planck Society in Germany.

However, compared to Lu Zhou’s casual attitude at the time of submission, this email made it difficult for the editorial department of Science.

Watering in Science is a lot of fun for the big cows, such as David Shaw, who has worked with Lu Zhou on the theoretical model of the interface structure of electrochemistry.

“Science” also welcomes these big cows to pour water on themselves. After all, the equipment of these big cows is often enough for the peers to be jealous. The quality of thesis has an academic reputation and also has its own “flow effect.”

However, the “watering” speed of the three-year submission of the Lu-Professor is too amazing.

The problem is not with the HCS-2 material itself, but that most of the mathematics editors in the editorial department don’t believe that Lu Zhou can make such a major change on the basis of HCS-1 materials in such a short period of time.

Consider the thesis of the carbon-sulfur composite material published in the recent JACS and the sensational effect in the energy industry.

Anyone has reason to suspect that the Lu-Professor may be competing with the Stanley Professional in the lithium-sulfur battery project, and in the case of modifying some of the experimental data, published an unfinished experimental result.

It sounds a bit risky, but in academia, such things are not without precedent.

The editorial department of Science made up his mind and eventually kicked the ball to the reviewer.

This time, the reviewer for the Foundation Professor is still the MBA of the MIT University of Technology.

As before, the “unbelievable” Professor, after receiving the review invitation, is still generously paying his own pockets. According to the experimental report provided by Lu Zhou, the experiment was repeated like an honest man.

However, regardless of whether he believes or not, the results are placed in front of him.

This time, he is also a pair of sun-baked
