After arranging Wei Wen's whereabouts, Lu Zhou turned around and returned to the office and continued to prepare his PPT.

During this time, his work would basically revolve around "theoretical models of electrochemical interface structures".

A week passed like this, and just when Lu Zhou finally completed his PPT, he suddenly received a call from Yang Xu.

As soon as the phone was connected, an excited voice came from the other end of the receiver.

"We succeeded! We did it! ”

Hearing the excited tone, Lu Zhou was slightly stunned, and then immediately asked, "Lithium-sulfur battery?" ”

Yang Xu, who was holding the phone, nodded vigorously, and said in an excited tone: "Hmm! Your idea is right, we used glucose as the precursor, selected polyaniline⁃ polypyrrole copolymer as the pore-making agent, and successfully synthesized hollow carbon nanospheres with a specific surface area of up to 3022m2/g and a diameter of only 69nm. ”

After taking a sip of water, Yang Xu, who was excited, moistened his throat and couldn't wait to continue.

"Then, we mixed the hollow carbon balls with sulfur elemental materials by chemical deposition and assembled them into a battery mold to test the performance of the battery pack, and the final results were quite encouraging."

"I won't talk about more things on the phone, I have sent the relevant experimental data to your mailbox, you can take a look at it quickly!"

"Okay, I'll go."

Seeing that Yang Xu's expression was so excited, Lu Zhou was also interested, so he casually turned off the video call and immediately logged in to his mailbox.

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

After downloading the attachments in the email, Lu Zhou used a professional reader to open the experimental data roughly organized into PDF format, and then read it carefully from the first part, line by line.

In this experimental data, there are not only battery performance test data, but also pictures taken with a scanning electron microscope and a change curve 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 is so excited.

Compared with the original hollow carbon nanospheres and the activated carbon nanospheres prepared by potassium hydroxide activation, the composite materials of the new hollow carbon spheres and sulfur exhibited superior cycling performance under the condition that the sulfur content was 70%.

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

The sulfur ions embedded in the hollow carbon ball can be removed from the surface pores of the hollow carbon ball normally, and the electrochemical reaction with the lithium ions moving to the positive electrode occurs in an orderly manner, and the generated Li2S2 and Li2S are silent in the space between the carbon balls, which avoids the pore blockage affecting the electrochemical cycle efficiency.

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

As we all know, the long-chain LiSn molecule that is easily soluble in organic solution is the culprit of the Shuttle effect, and if the formation of this product can be reduced from the generation mechanism, it is equivalent to preventing the loss of cathode materials from the source.

Moreover, even if the LiSn(n>2) compound is formed in a limited amount in the reaction system, due to the surface adsorption of this hollow carbon sphere, the polysulfide compound will be trapped in the backbone of the cathode material in large quantities, rather than diffusing through the surface of the material into the electrolyte.

With these two layers of insurance, the impact of the shuttle effect has been minimized.

Turning over the part that records the analysis of physical and chemical properties, Lu Zhou looked directly at the part of the battery pack test.

According to the experimental test of multiple battery packs conducted by Jinling Computational Materials Research, when the sulfur content is 73%, the inhibition ability of polysulfide compounds to the electrolyte reaches its peak. After 500 cycles, the Coulomb efficiency remains at a fairly high level.

When the sulfur content is 75%, the comprehensive performance of the battery reaches the best level by combining a series of factors such as coulombic efficiency, mass energy density, volume energy density and so on.

Regarding this new hollow carbon ball material, Yang Xu named it HCS-2 material in accordance with the naming principles previously formulated by Lu Zhou.

Compared with HCS-1 materials, which have relatively limited industrial application value, this new material is undoubtedly more likely for industrial production!

"It was just perfect."

Putting the experimental report in his hand on the table, Lu Zhou sighed in his heart, then took out his mobile phone from his pocket and called Mr. White Sheridan, the general manager of Star Technology, and asked him to immediately start applying for an international patent.

Considering the wide prospect of this material in the field of industrial applications, Star Technology will register patents separately in a series of aspects such as the compound, production, use, and mixing ratio with sulfur of HCS-2 material based on the research results, and establish a complete set of patent barriers.

If the situation is optimistic, he will be able to get the patent number by the end of the month, and then he can start writing his thesis.

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

Compared with the carbon-sulfur composite material itself, Lu Zhou is particularly looking forward to this......

……

White's work efficiency was very high, and it didn't take long for Lu Zhou to go down, and all the documents submitted for the patent application were successfully approved.

After getting the patent number, he immediately began to write his thesis.

He also wrote the last paper on HCS-1, and there are ready-made templates to apply, but this time the paper did not take Lu Zhou too much time, and the whole paper was completed in less than three days.

Considering that he would form a series with HCS-1, this time, he still chose Science as the submission object and sent the manuscript to the email address of the editorial office of Science.

After submitting the manuscript, Lu Zhou ignored it and began to prepare for the upcoming presentation at the Max Planck Society in Germany.

However, compared to Lu Zhou's casual attitude when submitting the article, this email made the editorial department of Science difficult.

Watering Science is a pleasure for many big people, such as David Shaw, who worked with Lu Zhou on a theoretical model of the electrochemical interface structure.

And Science also welcomes these big guys to pour water on themselves, after all, the equipment of these big bulls is often enough to make peers blush, the quality of the papers is guaranteed by academic reputation, and it also has its own "flow effect".

However, the speed of Professor Lu's three submissions in the past six months is too amazing......

The problem is not the HCS-2 material itself, but that most of the academic editors in the editorial office do not believe that Lu Zhou can make such a significant change on the basis of the HCS-1 material in such a short period of time.

Consider the recent publication of the paper on carbon-sulfur composites in JACS and the sensation it has caused in the energy industry.

There is reason to suspect that Professor Lu may have published the results of the experiments that have not yet been perfected in order to compete with Professor Stanley on the lithium-sulfur battery project, while modifying some of the experimental data.

This may sound risky, but in academia, such things are not without precedent.

The editorial board of Science couldn't make up their minds and eventually kicked the ball to the reviewers.

This time, Professor Bawangdi of the Massachusetts Institute of Technology is still in charge of reviewing Professor Lu's manuscript.

As before, after accepting the invitation to review, the "unbeliever" professor still generously paid out of his own pocket and repeated the experiment like an honest man according to the experimental report provided by Lu Zhou.

However, whether he believed it or not, the results were in front of him.

This time, he accidentally succeeded in double-clicking......
