For the gift, start research and development of graphene batteries

Chapter 32 Get back the 500 million that belongs to you

"How is it, is there a result?"

After Li Ming finished making the phone call, he waited for a while before entering the meeting room, and then asked.

"How should I put it, it stands to reason that I set up two project departments according to the company's requirements, and then led the development of graphene batteries, and the development was successful."

"Well, that's it."

"However, Baineng Company did not pay the project bonus as promised. It withheld the project team's research and development award on the grounds of my resignation. This is problematic. Director Li, you should be very clear about who developed the graphene battery."

"Therefore, I don't ask for anything else. I just want to get back the team project bonus that belongs to me. This is the reward this time. I don't know what Director Li wants?"

Jiang Ming said unhurriedly, now that he has discovered the problem, whether he can solve it or not, the initiative is his own.

I don't need to be in a hurry, but Baineng Company can't wait. Many companies are paying attention to the mass production of Baineng batteries.

If Baineng Company fails to deliver the products on time, then Baineng Company will be in trouble.

As for sending defective batteries to customers, anyone in their right mind would never do it.

Li Ming's face turned red after hearing Jiang Ming's request.

She understood Jiang Ming's request, 500 million.This amount happens to be the project reward for the R&D team.

Hunting geese all day long, but being pecked by geese.Li Ming sighed for a while.

To be honest, this amount is so large that Li Ming is unwilling to report it to the company.

After all, Jiang Ming was once his subordinate.If Jiang Ming did not leave his job, he should still be receiving a salary of more than 6000 yuan at this moment, and it would be a big deal to add him up to [-] yuan at most.

When problems arise, Jiang Ming will try his best to solve them.

Instead of spending nearly a hundred times the cost to solve this problem like now.

People often say that the most common things are the most precious, and this is the truth.

But it's useless to say anything, Jiang Ming has already left, and he is sure that Baineng Company, Baineng Company, has to give in.

It's just this amount, Li Ming's heart trembles when he thinks about it.

"Jiang Ming, can you?"

Li Ming begged for mercy.

But before Li Ming could say anything, Jiang Ming interrupted his words:

"Director Li, I'm just taking back what belongs to me, isn't that too much!"

Jiang Ming's tone was firm, and there was no room for negotiation.

"Jiang Ming, I understand your thinking. However, there is no precedent for this in Baineng Company."

Li Ming was still trying to persuade.

"Since there is no precedent, let's start now."

"Well, I can't decide this matter, I will report to the company leader."

Li Ming bowed his head and did not try to lower the price, so from Jiang Ming's tone, Li Ming could not see the hope of lowering the price.

At this moment, on the sample line, many process engineers are wandering around the battery production sample line, trying to find the problem.

Some are in charge of on-site operation instructions, some are in charge of equipment, some are in charge of lean production, and some are in charge of process optimization and quality improvement.

Numerous engineers were busy all the time, searching materials, personnel and equipment over and over again.

It's just that there was such a big movement, but everyone still couldn't find the problem.

Regardless of the problem, no one knows where the problem lies and what the solution is.

As for the several processes mentioned by Li Ming, it was analyzed from inside to outside, and the result was normal.

In desperation, the manager of the craft department had no choice but to report this problem to Li Ming.

Li Ming was dumbfounded after hearing the feedback that the problem could not be found.

I thought that the reason for haggling and haggling with Jiang Ming in the conference room was to give enough time for the technical department to analyze.

The result was good, and finally concluded that everything was normal, and Li Ming felt like vomiting blood.

"Manager Tu, is there not enough time? I can give you some more time."

Li Ming said this to Manager Tu of the craft department.

"Director Li, it's not a question of time. After all, the sample line is so long. We have been in contact with each other all year round, and we know everything clearly. This time, we really can't find a breakthrough."

"There is no breakthrough, no matter how long it takes."

The manager of the technology department gave this conclusion.

Li Ming was speechless, the performance of the craft department was really bad, Li Ming didn't know what to say.

There is no other way, Li Ming can only contact Mr. Guo to discuss the matter of Jiang Ming's remuneration.

Unexpectedly, Mr. Guo was not as angry as imagined for Jiang Ming's lion's big mouth, at least he was calmer than Li Ming imagined.

"Sign an agreement and give it to him, but things must be resolved. And there must be a special agreement that related hidden dangers must be resolved. This is the last optimization before mass production."

Mr. Guo explained.

"Otherwise, try to have a good relationship with Jiang Ming. We might be able to cooperate in the future."

Mr. Guo added.

This, Li Ming wondered, what did the company's leaders think, and how did they change back and forth?
You know, when reporting the 3 yuan lost wages at noon, Mr. Guo also scolded Li Ming.Said that Li Ming didn't think about the company, and agreed to any conditions.

This is the attitude now, the change is too fast!
"Mr. Guo, is there something wrong with Jiang Ming?"

Li Ming asked cautiously.

"Jiang Ming, for some reason, fell in love with old Mr. Wang Mingyang. The old man praised this kid very much, saying that he has created a new era or something. Don't offend Jiang Ming, otherwise the subsequent development of Baineng may be hindered. What."

Mr. Guo explained.

"Joke, this kid was not trained by Baineng, without Baineng, does this kid have a future?"

Mr. Guo looked disdainful.

Yes, they will get 500 million now.

Li Ming said in his heart.

"It doesn't matter to this kid, but Mr. Wang Mingyang still has to give face. Follow the old man's request."

Mr. Guo finally urged again.

It seemed that Jiang Ming's attitude towards Jiang Ming was as irrelevant as he said.Otherwise, it would be impossible for Li Ming and Jiang Ming to have a relationship.

On the sample production line, Mr. Wang, Li Ming, and a group of process engineers were on site, surrounding Jiang Ming, waiting for Jiang Ming to explain the process of the production line.

To be honest, up to now, everyone is still dissatisfied, waiting for Jiang Ming to ask a question, and find a way to refute it.

As for Li Ming, it is hoped that Jiang Ming's judgment is correct, so that the mass production of graphene batteries can be started as soon as possible.

"According to the production status of the sample line at noon, I found three problems. These three problems will cause the battery to deform more."

"In other words, the battery cycle diving is caused by these three production defects together?"

Master Wang Mingyang asked like this.

"Old Wang, you are right. If it is only one of the problems, at most, the battery will have a problem of excessive cycle life decay. But when the three problems are superimposed, the deformation intensifies, the capacity dives, and the life ends prematurely."

Jiang Ming explained.

Hearing Jiang Ming's words, there was a commotion at the scene, most of which were puzzled eyes.

But it has reached this level, and everyone didn't say anything, waiting for Jiang Ming to reveal the answer.

"First of all, the vacuum degree of slurry stirring did not meet the requirements."

Jiang Ming pointed to the vacuum mixer and said.

"What, there is such a situation?"

Hearing Jiang Ming's words, Manager Tu of the process hurried to the vacuum machine to check the usage records of the equipment.

In the record sheet, it is recorded that the vacuum degree set during the noon production of the equipment is 15KPA. This is a normal range. How could it fail to meet the requirements?

"Mr. Jiang, could there be a mistake? We all set it to 15KPA according to the requirements."

Manager Tu said so.

"My awareness is that the value of 15KPA is problematic, too low to meet the requirements."

Jiang Ming continued to explain that if he came out for a trip, he could collect 500 million. Jiang Ming's mood was exceptionally good, and he was correspondingly more patient.

These are the food and clothing parents, it is better to serve them!

"No, you see, it is stated in the document that a sufficiently high vacuum is required. According to our usual projects, 15KPA is already the highest, and any higher will destroy the surface tension of the material, resulting in a decrease in the density of the slurry."

Manager Tu explained with reason.

"That's for the positive electrode material, and for the negative electrode material, the vacuum degree is not up to the requirement. According to my calculation, it is estimated that the vacuum degree of 20KPa can meet the requirement."

"The 20KPA equipment can be fully achieved, but the surface tension of the material will be completely destroyed, which is not conducive to the slurry in the coating stage."

"Graphene batteries are different. The vacuum degree is too low and the surface tension of the material is too strong, which will cause the material to deform after cycling."

"Oh, so it is."

Everyone memorized Jiang Ming's point of view.

Professor Wang Mingyang next to him also had a thoughtful expression.

"As for the second problem, it is the coating stage, the temperature did not meet the requirements."

Jiang Ming continued.

"Could it be that the negative electrode material of this battery is special, and thus requires a higher temperature?"

In view of the problem of vacuum degree, some engineers asked and answered this question.

"That's not true. Although the material is special, the requirements for temperature are the same."

Jiang Ming said.

"You said it was a problem with our operation, which is impossible."

Manager Tu couldn't stand it anymore, and said quickly.

If the first problem of vacuum degree is because we don’t know the particularity of graphene batteries, it can be explained, but the temperature of the coating machine is set in advance and will not change. All batteries are In the same way, there is no problem of adjustment, why the temperature does not meet the requirements.

"According to my observation, the temperature of this coating machine is 0.1℃ lower than that of the coating machine next to it."

Jiang Ming pointed to the machine used for negative electrode coating and said to everyone.

"The coating machines for battery positive and negative electrodes are different. If the temperature is different, the quality of the coating will be different. It won't be obvious in the short term, but in the long term, there will be problems."

This.
Colleagues in the craft department changed their expressions drastically, and quickly turned on the machine to conduct a test.

Using a professional external thermometer, colleagues in the process department found that, sure enough, the temperature of one of the coating machines was lower than that of the other coating machine.

However, on the temperature monitoring interface of the coating machine, the temperature value is the same, and the temperature value should be displayed on the temperature sensor.

Due to the error of the temperature sensor, the temperature values ​​of the two coating machines are slightly different.

Coating machines have very high requirements for temperature consistency, and a temperature difference of 0.1 degrees is fatal.

"When was this coating machine calibrated? How could there be such an obvious problem?"

Li Ming also felt unbelievable. Logically speaking, the coating machine is regularly inspected and calibrated, so this kind of situation will not happen, but there is indeed a problem with this coating machine.

This is a bit strange.

Of course, compared to the temperature problem of the coating machine, everyone wants to know how Jiang Ming found out.

It should be known that the temperature difference of 0.1°C cannot be measured with ordinary equipment, because the accuracy of ordinary equipment cannot be achieved at all.

It can only be measured with a high-precision thermometer.

Could it be that there was a problem with this coating machine before, and Jiang Ming had already discovered it, but he didn't say it until now?
This is not possible, you know, Jiang Ming also used this coating machine to make samples before.

"Jiang Gong, can you help us clear up the confusion, how did you find out?"

Manager Tu of the craft department looked puzzled, wanting to know how Jiang Ming found out.

Therefore, even though he knew it was a bit inappropriate, Manager Tu still had the cheek to ask.If he didn't ask, Manager Tu felt that he might not be able to sleep for several days.

"This is simple, as long as you observe with your heart."

"Before I observed the disassembled battery, I found that the carbonization ratio of the positive electrode sheet was slightly higher than that of the negative electrode sheet. Moreover, the color of the positive electrode sheet was darker than that of the negative electrode sheet, and the degree of gelatinization was higher. Therefore, I judged that the coating of the electrode sheet At that time, the temperature of the two should be inconsistent."

Hearing Jiang Ming's words, everyone was taken aback.

Speaking of the carbonization ratio, this is well reflected in the numbers and can be seen.But everyone has also read the content analysis report. Although there is a difference in the carbonization ratio of the positive and negative electrodes, this cannot be the basis for judgment.

As for the color, it's even more ridiculous.The difference is only 0.1°C. Although there is a difference in color in theory, is it detectable by the naked eye?

Everyone couldn't help but doubt this.

Seeing this, Jiang Ming ignored it, and said in his heart whether you believe it or not, this is the explanation anyway.

Of course, with regard to the change in the temperature value, it can only be said that Jiang Ming does not only rely on these two factors for judgment.

What is more important is the concentration of graphene in the positive electrode. When the temperature is consistent, there should not be graphene in the positive electrode, but it is detected.

Then Jiang Ming conducted a reverse verification through the degree of carbonization and color, and finally confirmed it.

As for the concentration of graphene at the positive electrode, it is more troublesome to explain, involving a series of principles and theorems.If you want to explain clearly, it will not be able to be completed in a short time.

If Mr. Wang Mingyang wanted to know, Jiang Ming would be willing to spend his time, but for the others, forget it.

If you have this time, why do you have to waste so much talk?

In any case, the problem with the coating machine equipment has been confirmed by Jiang Ming.

What happens to Baineng Company in the future is their business.
