The top student must be diligent.

Chapter 201 The strongest battery in the new era!
Domestically, at a subordinate research institute of the Air Force Research Institute.

In the laboratory.

A full researcher squinted at a paper in his hand.

"First, in order to verify this model, we tested the most common interface reaction of ternary lithium batteries. The first test method was cyclic voltammetry with a scan rate of 50mV/s."

"According to experimental measurements, the oxidation peak potential is 0.42V, the oxidation peak current is 12.5μA, the reduction peak potential is 0.18V, and the reduction peak current is -11.3μA."

"According to the EIRM model's predictions, the data are: 0.41V, 12.4μA, 0.17V peak current, and -11.2μA."

"The margin of error is very, very low."

A researcher nearby nodded and said in amazement: "Yes, this error rate is too low, even a little unbelievable. I never thought that such a model could be developed."

The third researcher also nodded and said, "It feels like it has basically perfectly matched all the reactions at the microscopic level of the interface."

The researcher who spoke first continued, "There is more data than just this one. Look below. There is other data."

"Interface potential distribution test, the experimental results are: 0, -5, -10, -15, -20, -25, while the model predicted results are 0, -4.8, -9.7, -14.6, -19.5, -24.4."

"And the density of states... He was able to think of including the density of states, which was really a stroke of genius. This model also optimizes the density of states very well, with an average error of no more than 5%."

"Not to mention other things, such as the prediction of the electron tunneling effect, reaction kinetic parameters, analysis of electrochemical reaction products, etc."

For a moment, the researcher couldn't help but sigh: "I now want to invite the author of this paper to our institute to do research. With him, our research will definitely be twice as effective with half the effort."

Several people around laughed.

"That's a good idea."

"How can Xiao Yi, who now owns the Science Island Laboratory, come to our corner?"

"Let's not bring disaster to a talented young man. Let's just let us old guys carry on here."

"They can make some major achievements in other areas, why do they come here and study invisible coatings every day? We have made it, but for confidentiality reasons, we cannot let others know. The achievements they have made can bring glory to the country."

Hearing the opinions of the people around him, the first researcher rolled his eyes, waved his hands, and said, "Okay, okay, I'm just saying it. Why are you reacting so strongly?"

"Don't give me these nonsense. I think you are just worried that Xiao Yi will come. If he makes any achievements, you will be ashamed of yourselves."

The others were not embarrassed by being exposed, and laughed: "Come on, isn't it the same for you, old man?"

The researcher shrugged and said, "Okay, let's stop talking nonsense. This model will be of great help to our research on invisible coatings. Let's get started."

He pointed at the people present and said, "Don't forget, the stealth performance of the H20 has not yet met our requirements."

"Now that we have this model, we must at least improve the stealth performance a little bit, at least to convince those people at the Radar Research Institute."

Upon hearing this, the researchers present suddenly became serious.

Just kidding, they are in absolute competition with those people who research radar in China.

If the invisible coating they developed could be detected by the radar developed by those people, they would definitely be laughed at by those people.

"That's right."

"Work, work."

Having said that, they each began the research task at hand.

……

At the same time, on the other side, in the research institute specializing in radar research.

“Hey, have you guys seen this EIRM model?”

A researcher waved the paper in his hand and spoke to the other researchers present.

Soon, someone responded: "I've seen it. This model is really powerful. It has great significance for research in many fields of interface science."

"Indeed, this thing is also very useful for studying our radar."

"All the materials needed for phased array radars require interface research. Now that we have this model, it will also be helpful in designing related materials in the future."

"What you said makes sense, but I want to remind you that this model is far more useful to those who work on invisible materials than to us. You don't want to be laughed at by them, do you?"

"Fuck, that makes sense."

"Work, work."

Afterwards, these researchers also devoted their energy to the research.

People who study stealth materials don't want to be laughed at by people who study radar, and vice versa.

After all, given China's current international environment, the probability of a war with foreign countries is too small, and the technologies they have developed are unlikely to have the opportunity to be verified in actual combat, so their imaginary enemies can only be domestic opponents.

On the battlefield, radar and stealth fighters are natural enemies, so among researchers, those who study radar and those who study stealth materials become natural competitors.

If you want to prove that your achievements are great, you can only use your competitors as stepping stones.

Of course, it is probably precisely this competitive relationship that has made China a world leader in both radar technology and stealth technology.

……

As time goes by, the influence of the EIRM model continues to grow.

It can be regarded as a comprehensive model in the field of interface science. The electron-interface reaction migration model plays a huge role in too many fields.

For example, the field of stealth materials mentioned above, and the field of radar.

Almost any material may involve interface research.

Even the first wall material in the field of controlled nuclear fusion requires interface design.

Different interface designs can also affect the ability of the first wall material to resist neutron irradiation - of course, this has nothing to do with electron migration.

In summary, EIRM is more about the reaction process of electron migration behavior at the interface. Although it cannot include the entire interface science, its applicable fields are broad enough.

For a time, researchers around the world became increasingly agitated.

Especially those foreign scholars, who are now becoming more and more noisy because Xiao Yi's paper is in Chinese. Although there are already quite a few translated versions, there are still quite a lot of people who hope that Xiao Yi can write a translated version himself.

So many researchers have signed a petition, calling for "Xiao Yi to return to the international academic community!"

But no matter what, those translated versions are actually enough for them to read.

Speaking of this, something happened in the middle. Someone posted the translated paper on arxiv, trying to claim the paper as their own. But obviously, this paper was criticized to pieces not long after it was posted, and it was deleted within just two hours.

……

In the Science Island Laboratory.

“The number of downloads has exceeded 1.”

Liu Xiaodong and several others gathered in front of the computer, looking at the page above.

And this page is Xiao Yi’s personal website.

The above paper on the EIRM model has been downloaded over 10,000 times.

Chen Tao couldn't help but say, "If this paper wasn't in Chinese, the number of downloads would probably be even higher, right?"

"That's for sure. People abroad probably download versions that have been translated by others," said Tang Chunming.

"Is there a chance that Brother Xiao's paper will have more than 1 citations?"

"Although it won't happen in the short term, it is entirely possible in the long term."

"1 is nothing. Take a look at Brother Xiao's paper on absolute electronic calculations. The number of citations is about to break 2000. Wait a few decades, maybe his paper will be on the citation ranking list by then."

"I think it's possible." "Add one."

At this moment, a voice came from behind: "What are you looking at here?"

They turned around and saw Xiao Yi coming towards them.

Several people gathered around him and shouted, "Brother Xiao."

Although Xiao Yi is much younger than them, this does not prevent them from calling him brother.

Are you kidding? Are they going to call me Brother Xiao?
As for calling him Professor Xiao or Director Xiao, that would seem a bit strange, after all, they have been together for so many days.

So it is normal to call him Brother Xiao.

"Congratulations to Brother Xiao for his successful paper!"

Liu Xiaodong went up to him and just flattered him.

Several other people followed closely.

"Congratulations, Brother Xiao! Congratulations, Brother Xiao!"

Xiao Yi pulled the corner of his mouth: "Okay, okay, don't do it in this barber shop."

Liu Xiaodong chuckled and asked, "I see a lot of people want you to publish an English version now, why don't you do it?"

Xiao Yi waved his hand: "There are already so many translated versions, I'm too lazy to translate it."

"Okay, don't just sit here and do nothing. Follow my data and design process to start synthesizing a new lithium-phosphorus-sulfur-chlorine electrolyte."

He took out a few A4 papers and handed them to them.

Liu Xiaodong and others' eyes suddenly lit up.

"Brother Xiao has designed it so quickly?"

"I'll see, I'll see."

Soon they each took a piece of paper and looked at the preparation process listed on it, and their eyes lit up.

“This design…is amazing!”

“I think it should work this time!”

"Let's go! Go to the lab!"

Then, they all started to act with great enthusiasm.

Xiao Yi smiled slightly.

After the EIRM model was completed, he of course first used it in the design of lithium phosphorus sulfur chlorine.

After so many days of hard work, and using the optimized design of the materials he had mastered, he finally found the most suitable preparation process.

Looking at the excited expressions of the four people in front of him, he followed them and joined in the preparation work.

First, prepare several raw materials such as lithium sulfide, phosphorus pentasulfide and lithium chloride. After weighing the required amounts according to the proportion, mix them in a glove box filled with inert gas, and then place them in a ball mill for ball milling to ensure that the materials are fully mixed and reacted. After that, heat treatment is performed to promote the reaction of the materials and form LiPSCl solid electrolyte.

Of course, these are just basic processes. In order to make the properties of lithium phosphorus sulfur chlorine meet the requirements of the model, other means need to be added in the middle, as well as doping modification processes.

Just like that, after an unknown amount of time had passed, finally—

"finished!"

Xiao Yi picked up a piece of yellow crystalline film with tweezers. Because it has good mechanical properties, even though it is in the form of a thin film, it will not bend, just like a piece of yellow glass.

In fact, its structure is indeed like glass.

At the same time, because it has better surface stability than pure lithium phosphorus sulfur chlorine, this thing, which should not be exposed directly to the air, is not afraid of being corroded by air at this time.

According to theoretical calculations, even if it is exposed to the air for a week, its performance will not change much. According to estimates, even if it is exposed for a month, its performance will probably only decrease by about 1%.

Admittedly, a battery whose performance drops by 1% every month is definitely unacceptable in the mobile phone industry.

But the problem is that this electrolyte will not be as dangerous as liquid lithium-ion electrolyte, which will catch fire due to contact with air.

Perhaps the only thing you need to be concerned about is that if the battery drains too quickly, the battery may become seriously damaged just after the phone’s warranty expires.

Well... this is probably unnecessary worry, after all, the premise is that the battery is broken.

Of course, it would be unfair to only discuss safety for such a solid electrolyte.

The greatest function of such an electrolyte is naturally its energy density which far exceeds that of liquid electrolytes.

"Let's get started. Let's see what our battery performance can achieve with its help!"

Xiao Yi said.

"Yes!"

Liu Xiaodong and the others can't wait any longer.

Then, battery assembly begins.

The metallic lithium is used as the negative electrode, and the new type of lithium phosphorus sulfur chlorine is used as the electrolyte. At the same time, the previous carbon nanoporous material is attached to the lithium phosphorus sulfur chlorine solid electrolyte through the solution coating method.

Finally, there is sulfide polyacrylonitrile as the positive electrode.

After the battery assembly is completed, the charge and discharge test begins.

The number of cycles in this charge and discharge experiment is fifty times!
……

A few days later.

Fifty cycles are completed.

As the final results were tallied, the entire laboratory fell into shocked silence.

Energy density: 1231Wh/kg!

You should know that among the current various lithium batteries, the highest energy density is only around 300Wh/kg.

That's more than a four-fold increase in energy density, which is really...

It’s cheating!
Faced with this result, Xiao Yi also smiled slightly.

Theoretically, the energy density of lithium-sulfur batteries can reach about 2600Wh/kg.

Of course, this is achieved by ignoring all other qualities.

In actual batteries, the mass of electrolytes, conductive additives, binders and other structural materials also needs to be added, so it is generally lower.

Even with the addition of these other materials, the mass can still reach 1231Wh/kg, which undoubtedly shows how powerful the performance of this battery is.

Perhaps, a mobile phone that can be used for three or four days without charging, or a pure electric car with a range of 2000 kilometers will be realized in the near future.

To put it in a classic line: The future is already here.

Of course, it’s a little too early to break out the champagne just yet, as there are still some tests to be done.

For example, the lithium dendrite problem.

But in fact, they had already tested before that lithium dendrites were not a problem at all under the suppression of new carbon nanoporous materials.

Therefore, in the following experimental process, this new battery continued to demonstrate its extremely superior performance.

The cycle life is conservatively estimated to be 1500 times, and there is no problem of excessive growth of lithium dendrites under the most extreme conditions. At the same time, the performance is extremely stable regardless of high or low temperatures...

This will be the most powerful battery of the new era that will completely change the world!
