Ge Lingyue's words did not make Bill Gates show any displeasure, but bowed his head slightly and said: "That's okay, Ms. Ge can help us make an appointment, I will go to Huaxia to visit your company and meet with President Wang?"

Hearing this request, Ge Lingyue felt safe.

Well, after going around in such a big circle, it turned out that I still wanted to meet with my own boss.

"Of course, on behalf of the company, I welcome you to visit, and I am sure that Mr. Wang will definitely look forward to meeting you. I remember the last time you visited China in 2007, right?"

"Yes, it was a very interesting experience. Bill Gates said with a smile, as if caught in the memory of the past years.

After all, he was still the chairman of Microsoft at that time.

When accepting Bill Gates's invitation this time was not malicious, nor was it set to set up a grand banquet, Ge Lingyue only felt relaxed.

Really started to enjoy this rare trip to the mansion.

Even at the invitation of Bill Gates, he rewatched an American movie "Manchester by the Sea" more than ten years ago in a private theater, and then enjoyed a three-Michelin-starred sumptuous dinner in the private dining room of the villa, and after politely declining Bill Gates' invitation to stay overnight, he ended the trip and took Bill Gates's private jet and rushed back to Silicon Valley in California overnight.

Ge Lingyue is still quite satisfied with the schedule of eating and drinking with the reputation of this kind of boss.

......

Wang Yufei is still very satisfied with Shi Xulin's joining.

The next day happened to be the weekend, so he simply didn't go to the Quantum Research Institute as usual, but returned to the Brain Machine Club and talked to Senior Brother Cao and the senior brothers and sisters selected by Senior Brother Cao one by one.

The conversation with Shi Xulin allowed Wang Yufei to master a skill.

Can't think that people are definitely willing to join their own R&D team, maybe they have any requirements or unspeakable secrets?

Therefore, it is much better to invite directly face-to-face than to throw everything to Senior Brother Cao.

After all, Senior Brother Cao is also a person who is not good at words and does not know how to empathize.

It's probably called applying what you've learned.

According to the list, I chatted with a group of people from the Brain Machine Society, and after using the money ability to auction off the generous treatment of 60,000 monthly salaries plus food and housing, about one-third of the researchers of the Brain Computer Club were taken away, and most of them were prospective doctors.

As for the brain-computer club, what to do?

Believe in the ability of the director and those mentors to recruit people.

With the resources of one of the top universities in China, you will basically not fall into the dilemma of no one.

And in Wang Yufei's view, most of the researchers are now working on the next stage of brain-computer interaction tasks, which is a waste.

After completing the recruitment task of the Quantum Intelligence Brain Laboratory, Wang Yufei was about to discuss the personnel allocation with Senior Brother Cao, but received a phone call.

The call was from Lan Xuefeng, the leader of the solid-state high-energy battery R&D team of the Brain-Computer Society.

Generally speaking, Wang Yufei's contact with the members of the Brain Machine Club is generally through email.

Occasionally, I chatted a few words through WeChat.

His phone number has also been left for the leader or person in charge of the R&D team of several projects.

It is used to contact in case of emergency.

So far, however, none of the eight team leaders has called him.

This is the first time he has received a call from the project team leader, and Wang Yufei simply went to the corner of the second floor of the research room to answer the phone.

Then a young and excited voice came out of the earpiece: "President, we seem to have succeeded! We seem to have really succeeded! Oh my God, we have succeeded! Our solid-state battery cells have made a major breakthrough! The energy density has reached 3700Wh/kg!"

Wang Yufei scratched his hair unconsciously, and his mind quickly flashed the experimental projects and materials sent to him by the solid-state high-energy battery R&D team during this time, obviously these experimental data were not enough to achieve the goal of solid-state high-energy batteries.

After all, the R&D project set a relatively high goal for this technology at that time, first of all, the energy density of the battery cell should reach about 3000Wh/kg, while the current energy density of mainstream lithium batteries is only about 100-300Wh/kg.

It is equivalent to increasing the energy density of solid-state batteries tenfold in addition to researching them.

Even if it is not compared with ordinary lithium batteries, the energy density of Panasonic nickel-cobalt-aluminum ternary lithium cells currently used by Tesla is about 700Wh/kg, which must have more than quadrupled. You must know that even if Panasonic's current technological breakthrough is to hope that the energy density of the next generation of battery cells will increase by 10%.

Of course, in addition to this, the battery also has to take into account safety.

The spontaneous explosion and spontaneous combustion of Tesla's battery is not a new thing, and it is necessary to take into account the soaring energy density and ensure safety, which is the contradiction that R&D personnel need to solve.

But in any case, just listening to Lan Xuefeng's excited tone on the phone is enough to show that the R&D team has solved at least half of the problem.

"Wait, where did you make a major breakthrough?"

We have already manufactured battery cells with a unit energy density of 3300Wh/kg in the laboratory, and solved the interface problems that have been bothering us before!"

"Okay, where are you now?" Wang Yufei asked.

Whether it's just a misunderstanding in the laboratory, or a major breakthrough, it's worth Wang Yufei to see for himself.

"We are in the T3 laboratory of the New Energy Technology Research Institute. ”

"Wait, I'll come. ”

......

Wang Yufei rushed to the laboratory as soon as possible.

Whether it was a false alarm or not, he had to come and see it, otherwise it would discourage the experimental team.

Although he came abruptly and did not bring a certificate, relying on his face that was already famous in Huaqing, he still got the permission of the teacher to enter the research institute smoothly.

When he entered the lab, the whole group was there, and everyone was extremely excited.

However, there were no tutors in the laboratory, and apparently the group leader only informed him alone, and did not even mention the results to the teachers of the institute.

Of course, this is also understandable.

What if something goes wrong?

"What's the situation?" Wang Yufei asked directly.

"President, we seem to have really succeeded! We just went through another process of discharging and charging, and the test result is still the same. Team leader Lan Xuefeng said again excitedly.

"Yes, President, let's see if this is true!" said the group members.

"Wait, I'll look at the lab data first, and then you can show me a show. Wang Yufei changed into a lab coat and said quietly.

Wang Yufei began to study today's experimental process very seriously.

The experimental data here does not only refer to the individual results, but also to the entire experimental process.

In conjunction with the monitoring in the laboratory, it can restore every step of the experimenter's operation in the experiment.

Soon, Wang Yufei discovered several mistakes in what should have been a standardized test for the team members, but he didn't point them out, instead focusing on the solid-state batteries they had made.

"Here's the case, our goal in this experiment is to continue testing the space charge layer effect in the sulfide solid electrolyte, this time the medium chosen is ferrous sulfide, and then follow the standardized test procedure, this is our test data, you can also try ......"

Wang Yufei nodded, and then discharged and charged according to the test steps, and calculated the battery capacity and unit energy density.

Sure enough, the unit energy density of the incomplete solid-state battery in the laboratory reached 3678Wh/kg, far exceeding the previously set target.

And from the indicators of the laboratory, the performance of this solid-state battery in the laboratory is almost perfect, and the internal resistance of the battery is only 70 milliohms.

The smaller the internal resistance of the battery, the lower the heat generation and the higher the load capacity.

But this made Wang Yufei feel very puzzled.

Although he has made a lot of suggestions on this project, including the materials and structures selected now, according to his estimates, it will take many tests to solve the interface problem between the solid state, how can it be so simple and successful?

"This sample is kept for now. Repeat the experiment with other materials!"

"Good!"

......

The test did not start immediately, because of the management regulations of the laboratory, basically the materials to be used in the laboratory need to be applied for in advance, so there is no way to apply again for the materials that have been consumed just now.

But fortunately, the brain-computer club has put more effort into it.

For example, which laboratories are needed by the project team, Lu Jia, as the vice president, will go to say hello in advance. Because it is an unplanned use of the laboratory, the Brain Computer Club rents it directly in the name of the club, and for the laboratories that are often used, Lu Jia will also hire tutors in the laboratory for a fee.

Of course, most of these tutors will give those graduate students or doctoral students as one of the additional income.

Lu Jia has a sweet mouth, and he will not be empty-handed every time he visits, and he is very popular with the teachers.

In addition, after the previous controversies on the Internet, after the company raised the standard of project research and development funds, the requirements for the research and development of these groups are also higher, such as consciously restoring the laboratory to its original state after each test, and each time the test is conducted, a detailed test plan must be submitted to the laboratory teacher for reporting, assessing its danger, and so on.

Although these are all small things, these measures add up, and the teachers of the logistics department who manage the laboratory are not only relieved to conduct experiments with the brain-computer club, but also always give the green light. I quickly re-applied for the required documents.

The test started again, Wang Yufei didn't intervene, just watched the team members carry out the test step by step.

An hour and a half later, the experiment was completed again, but this time, it failed.

And the results are similar to the last experiment.

However, in Wang Yufei's opinion, this is the normal result.

In other words, success is an accident.

The entire project team was in an uproar.

"What's the situation?"

"Proportional issues?"

"If it doesn't exist, the proportion is absolutely right, and even if the proportion is wrong, the result cannot be so different. ”

"Material issues?"

"But this is a repeat trial, how can it be a material problem?"

The members of the group are in a mess, and of course, this is a very strange thing.

After all, both tests were conducted according to the test steps.

"Okay, let's not argue about that, let's retest the difference between the two sets of batteries. ”

Wang Yufei stopped the argument, and this time the test was carried out again around the experiment.

The results were the same, and the samples from the first test showed no problems with the energy density.

The second sample was still a failure.

"Wait, the powdery crystals used twice don't seem to be the same. But the crystals of the first time are yellowish, and the crystals used in the second time are black. The team member in charge of adding crystals said suddenly.

"Huh?"

"What do you mean? I got the wrong document the first time?"

Wang Yufei glanced at the group members and said, "Find the material label you received for the first time." ”

"I found it, I was really mistaken, the first time I used a mixture of FES2 particles. ”

"No, didn't you argue before that the volume expansion of FeS2 is large, so their contact loss with sulfide electrolytes will continue to increase?"

"It is not a simple FeS2 particle, but an in-situ synthesis of secondary FeS2 particles from the electrolyte. This should be the material requested by other labs. Wang Yufei took the label, read the instructions carefully, and said.

The group members looked at each other.

In the end, everyone's eyes fell on one of the team members, Pan Zeyu, and he was responsible for the materials.

"Don't look at me, I'm sure I'm not wrong with the list of materials, maybe the teacher made a mistake in his busy schedule, and I can't blame me, I'm not a chemistry student, so I'm not very sensitive to the properties of materials." And if it weren't for the wrong material for the first time, we wouldn't have been able to make a breakthrough, right?" Pan Zeyu was not very good, and hurriedly argued.

Wang Yufei also felt that the whole person was not very good.

So a retarded mistake in the laboratory, but the result is a breakthrough in the whole experiment?

Can you still play like this?

"Okay, let's not pursue these questions yet. Now the first step is to do laboratory analysis, analyze the data of the first success as soon as possible, and record the ratio of various materials. The second step is to keep all the records of the first experiment, and then our team needs some professionals to join, and your laboratory will also be transferred to the Changxiang Technology Building. Also, until the final success, I hope you will keep it a secret for the time being, after all, ......"

Wang Yufei can't say anything.

In fact, he wanted to say that after all, this was a beautiful misunderstanding, but it seemed a bit shocking to say so.

"Don't worry, President, it's all as you say!"

No one had any objections.

Everyone has signed an agreement at the beginning of the project, and if there is a real result in the end, it will naturally be distributed according to the agreement.

As for secrecy......

Well, really, if it's all the right steps and it succeeds, it's probably a little hard for everyone to keep it a secret. After all, a confidentiality agreement was signed.

But this time the situation is too coincidental.

In addition, most of the previous achievements were completed under the guidance of the instructor, so there is really nothing to be proud of.

If you have to be proud, you must probably be proud of everyone's European emperor physique!

That's so lucky!

The 1 in 10,000,000 chance they've been touched.

"Well, as long as everyone can accept it. In any case, our project has indeed achieved a phased breakthrough. I'll find someone to bring these two lab samples to the company for data analysis. In addition, although the energy density has been breakthrough, there are still many difficulties in completing the entire battery, and you can all participate in the next development process. Finally, bless you, although there is an element of coincidence, but this is not uncommon, and we generally call it an outstanding mistake!"

Wang Yufei said seriously.

"Okay, everyone has heard it, this is an outstanding mistake, but we don't need to show off for a mistake, let's complete our experiment step by step, by the way, there is less mention of this in WeChat!" Lan Xuefeng, the team leader, clapped his hands and said.
