The most fearful thing about anything is that the person who knows the truth is vague, and the person who listens carefully is good at brain supplementation.

After Lan Xuefeng told him what was going on in the laboratory accidentally, Han Jingchang felt that he understood, and quickly grasped a few key points!

First, this mysterious tutor always replies to students late at night;

Second, this mysterious tutor couldn't rush to the capital to do on-site tutoring for students;

Third, due to various reasons, after achieving significant results, Changxiang Technology, as the biggest beneficiary, felt that it was not appropriate to send the specific situation of the experiment to this mysterious mentor in the future, especially if the success of this experiment was due to an accident;

Combining these three points, as a scientist with rigorous logical judgment ability, Han Jingchang quickly came to a conclusion, this is probably a Chinese scientist doing research on the same project in the Western Hemisphere, because of the time difference, so he always replies to emails late at night, and naturally there is no way to do on-site tutoring.

At the same time, because it is a peer, and because it is a person abroad, it is naturally impossible for Changxiang Technology to give the laboratory data after the breakthrough of the project to the mysterious mentor unconditionally.

When you think about it, everything can be explained, and this must be the case.

This also made Han Jingchang feel an extremely glorious sense of mission.

Why did you come to him?

This is a full trust in him that he will not leak some confidential data.

From beginning to end, Han Jingchang never suspected that this mysterious mentor was played by Wang Yufei.

Wang Yufei is a genius, yes, but his ability is more reflected in programming and hardware design.

Solid-state high-energy batteries belong to materials science and energy science, how can they all be understood?

So Han Jingchang showed a clear expression and said to Wang Yufei: "Okay, I understand your difficulties, but I still want to know which mentor it is?

Han Jingchang sighed inwardly.

I have to say that the hard and soft power of Changxiang technology is very strong!

The mentor invited is naturally very powerful, and his luck is very good, this kind of laboratory mistake can even achieve a super technology by mistake, Han Jingchang really hasn't experienced it.

However, the question he asked made Wang Yufei's face look embarrassed, and then replied apologetically: "Professor Han, it's really not that I want to hide it from you, but it's really a secret. When the scientist promised us to tutor the members of the Brain Machine Society, one of the most important things was to keep his identity strictly secret. If you think about it, he doesn't want to reveal the identities of the students he supervises, and of course we have to keep it strictly confidential. ”

Han Jingchang nodded.

For Wang Yufei's explanation, he couldn't find a loophole.

Obviously, this big man is either concerned about the country and wants to help the country cultivate a few talents, or he wants to earn some extra money in his spare time. But no matter what kind of idea they have, they obviously don't want people to know their identity.

"It's a pity!"

Han Jingchang let out a long sigh, then looked at Lan Xuefeng and asked, "Can I take a look at the emails you exchanged before?"

"Of course, Mr. Han, there is a computer outside, I will call it for you now. ”

Wang Yufei didn't say anything, he used the company's intranet mailbox, but it was a previous test mailbox.

Of course, it can also be explained that these emails have undergone secondary turnaround.

Fortunately, Han Jingchang didn't seem to pay attention to the email address, but concentrated on studying the previous test data and process.

Others continue to do some basic testing around cost.

These are extremely valuable pieces of data, and no one feels like a waste of time.

About an hour later, after Han Jingchang understood the situation, he stood up and said, "Okay, I'll be this tutor." Since the mysterious mentor refused to leave his name, I will not leave it alone. When the time comes, let's write a brain-computer club tutor. ”

The meaning of these words is clear.

I don't take advantage of the children, so the technology won't show its face, just be a tutor. If you don't show your face, you won't be involved in the issue of patent ownership.

Wang Yufei, who has learned a little about how to deal with people, immediately said: "Thank you, Professor Han, Changxiang Technology will specially hire you as a special researcher of the company, responsible for the counseling work of this laboratory." ”

Han Jingchang looked at Wang Yufei, was happy, and replied: "Okay, you are a confidential unit here, and without this identity, it is not easy for me to come in." And having the identity of a distinguished researcher is good to sign a confidentiality agreement, and today's children are thoughtful, which is really incomparable. But can I ask what kind of treatment that mysterious mentor is? That's a real master! Those directions in the laboratory are really valuable!"

"If he hadn't provided the whole battery manufacturing and experimentation ideas, you wouldn't have been able to make this kind of result even if you made a thousand mistakes in the lab! But there's one thing I want to tell you and these kids. If you're going to take the lead, you're going to have to hurry! According to my judgment, the group led by the mysterious mentor is probably just short of the final catalytic material! It won't be long before their lab will come up with a similar lab product and announce it. If you want to get the most out of it, you really have to hurry!"

Han Jingchang said seriously.

Wang Yufei smiled and subconsciously touched his nose.

Well, that's kind of a compliment to him, right?

After seeing the stunned children of the project team, Wang Yufei actually wanted to comfort them. After all, he is the mysterious mentor, so it is almost impossible for others to have similar techniques.

But after thinking about it, Wang Yufei still didn't say it.

It's also good to give people a sense of urgency.

In the end, he just said: "Well, then please ask Mr. Han, I hope that under the leadership of Mr. Han, we can make this project the first to come out of our hands." ”

"Okay, but then again, speed is not enough, and we're a lot ahead now. As long as it is steady, it is not a big problem. It's up to everyone next!" Han Jingchang patted Lan Xuefeng on the shoulder and said.

......

After arranging the mentor of the brain-computer club project team, Wang Yufei's life returned to normal.

Although there is Han Jingchang, a distinguished researcher, Wang Yufei still asked Senior Brother Cao to bring a group of senior brothers and sisters from the Brain Computer Research Society to report to the company.

The first task is to familiarize yourself with the operation of the equipment in the Quantum Laboratory.

This is no joke, some high-end CNC equipment, especially the one with its own operating system, just to learn how to carry out basic operations will take nearly a month or two. Even if these graduate students and doctoral students are all familiar with their hands, a one-month run-in period is indispensable.

When you are free, you can also go to the battery lab to help.

Fortunately, there aren't many places that need help.

After the busy examination season, all members of the entire high-energy solid-state battery project team became temporary employees of Changxiang Technology, and the HR department arranged four collective rooms for them within the company after obtaining the consent of the team members.

In this way, you can eat and live in the company, and basically make perfect use of this summer vacation and devote yourself to scientific research.

Not to mention how much economic benefits can be brought by the results, there are famous teachers who stare at it every day, basically after a month of running-in, all kinds of operations in the laboratory can be ripe.

At least in terms of hands-on ability, it is certainly not inferior to graduate students.

There are also benefits for Wang Yufei.

Although the team members still routinely hold a sharing meeting after the test every day, they will no longer sort out the information and send it to Wang Yufei by email.

However, Wang Yufei can directly retrieve all laboratory data and data from the background server, and can directly restore all laboratory operation processes through various video materials, which is even more convenient.

Therefore, Wang Yufei can also focus on the quantum superbrain, and of course, he will regularly browse the progress of the high-energy battery every night.

In fact, the most critical material part is solved, and the remaining problems are not very complicated.

But Han Jingchang obviously came with the mentality of guiding the children to become talents.

Just one laboratory code issue, any bit of violation, will be severely reprimanded, along with repeated guidance.

This directly leads to a slower progress in the early stage.

According to Wang Yufei's estimate, it will take at least a month to study the optimal ratio of internal material matching.

However, I didn't expect that although Han Jingchang's strict requirements in the early stage slowed down the progress, the speed was faster after that.

In particular, the entire high-energy battery R&D team is highly motivated.

Although the company did not specify how long the task would take, it was probably because several of the children were too excited and the young people were very energetic. After getting the guidance, the ability has also been greatly improved, and the speed is getting faster and faster the further back you go.

Han Jingchang basically rushed to the laboratory in the morning every day, and left work on time at about 7 or 8 o'clock in the evening.

But after Han Jingchang got off work, the eight children discussed it and simply divided into two shifts and took turns working overtime to catch up with the progress.

The first class followed Han Jingchang's schedule, and the other half at least worked in the laboratory until one or two o'clock in the morning, and then carefully took all the experimental notes and recorded all the data before returning to the dormitory to rest together.

can be so serious and desperate, and it is likely to be related to a group of children who want to say goodbye to the team led by the mysterious mentor.

After all, according to Han Jingchang, they had obtained this achievement under the guidance of that mysterious mentor, which was enough to show that there was an invisible enemy behind them chasing them.

At this time, the previous mysterious mentor became the biggest motivation for them to study hard.

In this way, it only took more than half a month to determine the optimal ratio of internal materials, and several finished products were made, and the unit energy density also reached an astonishing 4300 watt-hours per kilogram.

What is this concept?

For example, Biyoudi, a well-known domestic new energy vehicle company, uses high-nickel ternary materials for the positive electrode of the ternary battery used in its new energy vehicles, and the negative electrode uses silicon oxide or nano-silicon, with an energy density of about 320 watt-hours per kilogram.

That's about a fraction of a new battery.

Even the Sony batteries used by Tesla have a single specific energy of 750 watt-hours per kilogram.

To put it bluntly, once this technology is made public, it will bring about an earthquake in the entire new energy vehicle industry.

It is also a major positive for the mobile phone industry.

Of course, energy density alone is not enough.

After a batch of batteries was produced in the laboratory, a series of tests began under the auspices of Han Jingchang.

Over-charge, over-discharge, external short circuit, forced discharge, etc., circuit test.

Extrusion, needling, shock, vibration, drop, etc., mechanical testing.

High and low temperature cycle, combustion, microwave heating, etc., temperature test.

High-altitude and low-pressure simulation, salt spray test, etc., environmental test

......

After a series of tests, it took about half a month to complete, everything was ready, and the most exciting moment was coming.

The lab was already scheduled to officially announce the news two days later, on Sunday, August 2.

The conference was prepared for about a week, funded by the company, but held in the name of Huaqing Brain Machine Club, of course, the protagonist of this conference was not Wang Yufei, but Lan Xuefeng and his group members.

In fact, the company had already started to warm up the product launch and start negotiations with manufacturers who could work with the whole project.

It's just that it is not directly named as a breakthrough in the field of solid-state high-energy batteries, and the external publicity caliber is that with the support of Changxiang Technology, the project previously selected by Huaqing Brain Machine Society has achieved a major breakthrough, and it was officially announced on August 2.

Generally speaking, it is difficult for this kind of propaganda to break the circle and cause a sensation.

But because the company directly put this project on the official website, it quickly attracted the attention of many technology enthusiasts.

And when the news spread, the turmoil of the previous brain-computer club was turned over again.

After all, after the official establishment of Huaqing Brain Machine Society, a total of eight projects were approved, but they were widely criticized.

Most of the people felt that Wang Yufei was floating, and he was tinkering with some projects that attracted the lofty ambitions in front of him.

At that time, the brain-computer club chose to treat it coldly, did not participate in online debates, re-reduced its staff internally, allowed members with unstable mentality to quit the club, and stopped a series of measures such as the club's continued recruitment, which made this topic cold.

Immediately after the Xin system was sniped by Microsoft, the topic of the brain-computer club was gradually overshadowed.

But who would have thought that it had only been more than three months, and the Brain Machine Club would have re-provoked this topic.

So, with the memory of the Internet, the eight projects that were originally established were picked up by enthusiastic netizens again.

At the same time, because Changxiang Technology did not announce which technology had a breakthrough on the official website, it also instantly aroused the curiosity of many netizens.

So this topic on the Internet has stirred up again.

The hype on the Internet is one thing, but the large group within the brain-computer club has exploded directly these days.

Internally, it must be known that it was the solid-state high-energy battery pack that made a breakthrough, which is easy to guess.

After all, there are only more than 100 people in the entire brain-computer club, and there are 76 people in the eight project teams.

Even if the research battery research team strictly adheres to the confidentiality agreement, and the other seven project team members can be found to use the elimination method, and it will be possible to know which team made the breakthrough.

The only thing I don't know now is where the major breakthrough of the battery pack project is.

After all, the official didn't say it very clearly, and only used a major breakthrough to summarize.

Many students have asked familiar group members in private, but unfortunately they have not received a response at all.

Not to mention that the whole group was already busy with their feet on the ground, and the principle of confidentiality was stuck, and the group members themselves hoped to surprise everyone at the last moment. Of course, even if you want to show off, it is very troublesome, and the mobile phone is confiscated at the critical moment. Every day, I set aside a special time to call home through the landline.

So the discussion in the group was lively, but the eight of them couldn't participate.

Of course, they must be more excited than the rest of the group.

After all the tests were done, everyone was waiting for the press conference to make a splash.

Although Han Jingchang doesn't come to the lab much anymore, they still prepare for the presentation at the press conference over and over again.

In addition to the PPT, eight people often get together to discuss how to show everyone the power of the new battery.

After discussing the specific measures, it is to contact the staff of the press conference and prepare other external equipment for them.

In short, the internal excitement is a mess.

......

Wang Yufei decided not to communicate directly with potential partners, but to prepare a grand press conference under strict confidentiality, of course, with his own considerations.

To put it bluntly, he wants to correct the name of the brain-computer club.

It turns out that as long as the members of the brain-computer club are good enough, early exposure to more professional content is not a seedling boost.

Of course, the main thing is that Wang Yufei has the confidence to guide these people on the right path.

But in any case, the brain computer club, as an important talent screening base for imagining science and technology in the future, cannot afford to lose.

The problems that happened before made the brain-computer club stagnate for nearly four months, so now, of course, we have to take advantage of the impact of this press conference to regain the time wasted before.

Everyone says that these projects are to pull out the seedlings, so now that we have proved that the Brain-Computer Society is capable of turning these projects into real technology, who would dare to say that this thing is being pulled out and promoted? Who would dare to judge the members of the Brain-Computer Society?

That's the ultimate goal of the launch.

Making money is secondary, fame must be resounding!

Of course, Wang Yufei did not spend too much energy on the press conference, and the company has a special person in charge of this part.

He is now mainly busy with his own quantum brain laboratory.

All the assistant researchers in the laboratory are basically in place.

He is naturally the core of the entire laboratory, Senior Brother Cao serves as the director of the laboratory, and the twelve senior brothers and five senior sisters recruited from the Brain Computer Research Institute are all assistant researchers, and then Lu Yuxin and Shi Xulin specialize in handling the data analysis work of the laboratory.

A total of twenty people were divided into three groups, each responsible for the research work in three laboratories.

Now everyone is learning and familiarizing themselves with the laboratory equipment they need to operate.

The official opening of the Quantum Intelligence Brain Laboratory is also scheduled to be officially launched on Monday, August 3, the day after the release of solid-state super batteries.

Before that, Wang Yufei has another very important thing.

Ge Lingyue ended her nearly two-month international trip and returned to China in a hurry.

And she is not the only one who has returned to China this time, there is also a big man, Bill Gates.

This time, Ge Lingyue returned to China on Bill Gates's private jet and a Boeing 757.

The world's richest man has a total of three private jets, in addition to this Boeing 757, there is also a Challenger 604 and a Bombardier BD-700 Global Express. The last time Ge Lingyue rode on the Challenger 604.

This time, probably because the whole team returned to China together, there were more people, and it was a long-distance voyage across the ocean, so the Boeing 757 was used. Although it is not possible to fly directly to the capital due to the flight and need to refuel at the transit airport in the middle, it is still much more comfortable to fly across the ocean by this private jet than by large plane.

The plane landed at Beijing International Airport at 7 a.m. on August 1.

In view of the sincerity expressed by the other party, Wang Yufei also gave face and personally went to the airport to pick up the plane.

Of course, it's not just to pick up Bill Gates, Ge Lingyue is also very hard to go out this time.

After all, he has been out for more than two months, and the results are remarkable, as the boss Wang Yufei feels that this trip should also be made.

Because Bill Gates did not make a big splash in China this time, Changxiang Technology did not prepare a welcome ceremony.

After the two met, they just shook hands briefly, and then took Bill Gates to visit the headquarters building of Enjoy Technology according to the previous itinerary. During this period, Ge Lingyue also found an opportunity to report to Wang Yufei alone.

In fact, there is nothing to report on the work.

Basically, negotiations with large foreign companies will eventually send the contract to Wang Yufei for review.

It was mainly domestic achievements, some of which shocked Ge Lingyue.

"Boss, the results of the battery project of the Brain-Computer Club are really not a joke, right?"

"Of course it's not a joke, tomorrow is going to be a development conference, how can it be a joke. ”

Ge Lingyue swallowed unconsciously.

In fact, her rush back to China had a lot to do with the project.

Although no one has said it so far, if this project is really successful, the benefits will be too great for Changxiang Technology!

You must know that according to the previous agreement signed with the Brain Machine Society, Changxiang Technology sponsors all the projects of the Society, and if the results are produced, Changxiang Technology will be able to own its intellectual property rights. And 70% of this part of the income belongs to Changxiang Technology, 10% belongs to the brain-computer club, and the remaining 20% belongs to the entire team.

Once the solid-state high-energy battery project is released and mass production begins, the profit is incalculable.

What's more, although Ge Lingyue has not been able to see the complete experimental report abroad, according to his communication with Wang Yufei, he has basically solved the problem of mass production in the laboratory. Moreover, the materials used are not expensive, and the mass production cost is probably the same as the current mainstream liquid lithium battery production cost, and it is even estimated to be cheaper than the mainstream battery product 18650 currently supplied by Nichishima Sony to Tesla.

And it's more secure.

What is this concept?

Batteries produced at the same price can last six to twelve times longer, with fewer natural and explosive failures.

Not to mention the use of mobile phones, notebooks and other electronic products, after the product launch, the new energy vehicle industry alone will have to break through!

As the CEO of a company, can Ge Lingyue not be excited?
