After arranging Wei Wen's whereabouts, 6 Zhou turned back to the office and continued to prepare his ppt. & 1t; /

During this time, his work will basically be carried out around "theoretical model of electrochemical interface structure". & 1t; /

After a week like this, when 6 Zhou finally finished his ppt, he suddenly received a call from Yang Xu. & 1t; /

As soon as the phone was connected, an excited sound came from the earpiece. & 1t; /

"We succeeded! We succeeded!" & 1t; /

Hearing that excited tone, 6 Zhou took a moment to choke, and immediately asked: "lithium-sulfur battery?" & 1t; /

Holding the phone, Yang Xu nodded his head vigorously, and said in a tone of excitement: "Yeah! Your idea is right. We used glucose as the precursor and selected the copolymer of polyaniline and polypyrrole as the pore-forming agent. We successfully synthesized a specific surface area of ​​3o22m2 / g, and hollow carbon nanospheres with a diameter of only 69nm. "& 1t; /

After drinking a saliva, Yang Xu, who was excited, ran his throat and couldn't wait to continue. & 1t; /

"Then, we mixed this hollow carbon sphere with sulfur elemental material by chemical deposition method, assembled it into a battery mold, and tested the performance of the battery pack. The final result is quite satisfactory." & 1t;

"I won't talk on the phone about too many things. I have already reached your mailbox for the relevant experimental data. Please take a quick look!" & 1t; /

"Okay, I'll go now." & 1t; /

Seeing Yang Xu's expression so excited, 6 Zhou was also interested, so he turned off the video call and logged in immediately. & 1t; /

Within five minutes, he received an email from Yang Xu. & 1t; /

After downloading the attachments in the email, 6 Zhou opened the experimental data roughly arranged in pdf format with a professional reader, and then began to read it carefully line by line from the first part. & 1t; /

In this experimental data, not only the battery performance test data, but also the pictures taken with a scanning electron microscope and the change curves drawn according to various data. & 1t; /

As Yang Xu said, the performance of this new material is very good, and it is no wonder that his voice will be so excited. & 1t; /

Compared with the original hollow carbon nanospheres and activated carbon nanospheres prepared by the activation of potassium hydroxide, this new type of hollow carbon sphere and sulfur composite material exhibits superiority at the same sulfur content of 7o%. Cycle performance. & 1t; /

At the macro level, the changes at the micro level are also quite interesting. & 1t; /

The sulfur ions embedded in the hollow carbon spheres can be desorbed normally from the surface pores of the hollow carbon spheres, and they can generate an electrochemical reaction with the lithium ions moving to the positive electrode in an orderly manner. The gap is silent, avoiding clogging of the pores and affecting the efficiency of the electrochemical cycle. & 1t; /

On the other hand, because the charged sulfur ions have limited contact with the lithium ions moving to the positive electrode, the formation of the long-chain compound 1 isn is largely avoided. & 1t; /

It is well known that long-chain 1isn molecules that are easily soluble in organic solutions are the culprit of the shutt1e effect. If the formation of this product can be reduced from the generation mechanism, it is equivalent to preventing the loss of the cathode material from the source. & 1t; /

Not only that, even if 1isn compounds are limitedly formed in the reaction system, due to the surface adsorption of this hollow carbon sphere, this polysulfide compound will be retained in a large amount in the framework of the positive electrode material, instead of passing through the material The surface diffuses into the electrolyte. & 1t; /

With these two layers of insurance, the impact of the shuttle effect has been minimized. & 1t; /

After turning over the part that recorded the analysis of physical and chemical properties, 6 Zhou directly looked at the part of battery test. & 1t; /

According to the experimental tests of multiple battery packs made by Jinling Computing Materials Research, when the sulfur content is 73%, the ability to inhibit the diffusion of polysulfide compounds into the electrolyte reaches a peak. After 5oo cycles, Coulomb efficiency is still maintained at a fairly high level. & 1t; /

When the sulfur content is 75%, a series of factors such as coulomb efficiency, mass energy density, volume energy density, etc., and the comprehensive performance of the battery reach the optimal level. & 1t; /

Regarding this new type of hollow carbon sphere material, Yang Xu named it hcs-2 material according to the naming principle previously formulated by 6 Zhou. & 1t; /

Compared to the hcs-1 material, which has a relatively limited industrial application value, this new material is undoubtedly more industrially possible! & 1t; /

"It's perfect." & 1t; /

Putting the experiment report in his hand on the table, 6 Zhou sighed in his heart, then took out his mobile phone from his pocket, called Mr. White Sheridan, the general manager of Xingkong Technology, and let him immediately start to carry out international patent Application. & 1t; /

Taking into account the broad prospects of this material in the industrial application field, based on the results of this research, Star Sky Technology will separately register patents around a series of aspects such as the compound, production, use, and mixing ratio with sulfur element of hcs-2 material. Establish a complete set of patent barriers. & 1t; /

If the situation is optimistic, he can get the patent number before the end of the month, and then he can start writing the paper. & 1t; /

As a model for solving practical problems using computational material methods, the success of hcs-2 materials will undoubtedly provide an important factual argument for his theoretical model of electrochemical interface structure. & 1t; /

Compared to this carbon-sulfur composite material itself, the 6 boat is particularly looking forward to this ... & 1t; /

... & 1t; /

White's work efficiency is very high. Six boats ordered not to go long, and all the documents submitted for patent applications have successfully passed the application. & 1t; /

After getting the patent number, he immediately started writing the dissertation. & 1t; /

The last paper on hcs-1 was also written by him, and there are ready-made templates to apply. This time, the writing of this paper did not take too much time, and the entire paper was completed in less than three days. & 1t; /

Taking into account a series with hcs-1, this time, he still chose to be the object of submission, and sent the manuscript to the mailbox of the editorial department. & 1t; /

After submitting the manuscript, 6 Zhou didn't manage it any more, and began to prepare for the upcoming report meeting at the Max Planck Institute in Germany. & 1t; /

However, compared to the casual attitude of 6 Zhou in submitting the manuscript, this email has made the editorial department more difficult. & 1t; /

Irrigation on the water is a lot of fun for the big cows. For example, David Shaw, who has cooperated with 6 Zhou on the theoretical model of the electrochemical interface structure, is one of them. & 1t; /

And they are also very welcome to irrigate themselves at www.wuxiaspot.com ~ After all, their equipment is often enough to make their peers jealous, the quality of their papers is guaranteed by their academic reputation, and they also have a “flow effect”. & 1t; /

However, the degree of "irrigation" of Professor 6's three submissions in the past six months is too amazing ... & 1t; /

The problem is not the hcs-2 material itself, but that most academic editors in the editorial department do not believe that the 6 boat can make such a significant change on the basis of the hcs-1 material in such a short time. & 1t; /

Taking into account the recently published paper on carbon-sulfur composites, and the sensational effect in the energy industry. & 1t; /

Anyone has reason to suspect that Professor 6 may be in order to compete with Professor Stanley on the lithium-sulfur battery project. In the case of modifying some experimental data, the experimental results are not complete. & 1t; /

This may sound risky, but in academia, such things are not without precedent. & 1t; /

The editorial department couldn't decide, and finally kicked the ball to the reviewers. & 1t; /

The man responsible for reviewing Professor 6 this time is still Professor Bawangdi of MIT. & 1t; /

As before, after receiving the invitation to review, the "unbelieving evil" professor still generously paid for himself, and repeated the experiment like an honest man according to the experiment report provided by 6 Zhou. & 1t; /

However, whether he believes in evil or not, the results are before him. & 1t; /

This time, he accidentally succeeded again ... & 1t; /
