For the gift, start research and development of graphene batteries

Chapter 31

I am like a primary school student, I don't know anything, and I have to be carefully explained by others, which is a bit embarrassing.

"Let's not talk about this, what is the capacity of the graphene battery diving this time related to?"

Wang Mingyang knew that to solve this problem, Jiang Ming had to take action, and no one else could solve it.It was enough to be hit, Wang Mingyang hurriedly brought the topic back to the main topic.

"This, so far, is not clear. I did a simple calculation just now, and it has nothing to do with what I said. After all, these points have been considered at the beginning of the battery design, and it stands to reason that there should be no more problems."

Regarding the capacity of diving, Jiang Ming was also very puzzled, and for a while, he had no good ideas.

But it can't be solved now, and it's normal. Jiang Ming just came to the laboratory, and it's not easy to verify so many.

After all, this is a money-making business, and it is his first business. Jiang Ming still wants to make a good impression on Li Ming.After all, the follow-up is still counting on it to continue.

Therefore, Jiang Ming felt that he had to be quick and try his best to solve it.

Thinking of this, Jiang Ming didn't speak any more, but looked at the data seriously, and at the same time checked the anatomy of the defective products.

After Li Ming reported to Mr. Guo and left the office, Li Ming suddenly announced something: Professor Wang Mingyang is still in the laboratory.

This created a situation where Baineng invited two groups of people for the same event, and these two groups did not know each other.Thinking of this, Li Ming was in a cold sweat.

This kind of operation is a taboo in business.After all, in the eyes of the employer, this is distrust of himself.

Li Ming put down the work at hand and rushed to the laboratory in a hurry.

"I hope the two of you haven't met yet."

Li Ming prayed in his heart.

When Li Ming arrived at the laboratory and saw Jiang Ming and Wang Mingyang in the same room from a distance, Li Mingxin finished speaking.

Feeling anxious, Li Ming approached and looked from a distance. At this time, Jiang Ming was sitting on a chair, and Professor Wang Mingyang was sitting beside him, like an assistant.The two sides focused on analyzing the problem, and neither side seemed to have any doubts about it.

Seeing this situation, Li Ming was dumbfounded. What's going on? The two people are so peaceful with each other?

To say that Jiang Mingping and Li Ming can understand, after all, Jiang Ming's status in the industry is low.But what is the situation of Professor Wang Mingyang, why is he so calm at the moment, this is a bit abnormal.

"Director Li, you came at a good time. You can arrange to dissect all these batteries and analyze the components in their electrolytes."

Seeing Li Ming's arrival, Professor Wang Mingyang arranged for it bluntly.

Of course, this matter can only be arranged by Li Ming.

Because the sample cells are limited, others cannot arrange the dissection of the cells at will and can only conduct analysis on the basis of the dissected cells.

Wang Mingyang and Jiang Ming had a discussion just now, and both of them thought it was necessary to compare the original samples with the samples produced later.

Because just now Jiang Ming discovered an important phenomenon, that is, the first few samples he made seemed to have no problems.

The problematic ones are just the samples produced by Baineng Company according to the process given by itself.

Jiang Ming wanted to see what had changed inside the handmade samples he made at the beginning and the cells made in small batches later.

How could Li Ming disagree with Wang Mingyang's request, and quickly arranged for an engineer to conduct an autopsy.

Looking at the disassembled samples and the test report of the contents, Jiang Ming thought deeply.

"Professor Wang, what do you think?"

Jiang Ming asked. It stands to reason that Wang Mingyang, as a senior, should have asked Jiang Ming in a supportive manner. The result was good, but now it's the other way around, which is puzzling.

But Wang Mingyang didn't feel that there was anything wrong with it, after all, those who are successful come first.In the field of graphene batteries, as a latecomer, I still have a lot to learn.

Moreover, through the communication with Jiang Ming just now, Wang Mingyang knew that Jiang Ming could not guess with common sense.After all, who would have thought that Jiang Ming would know so many professional mysteries.

At this moment, the roles of the two parties have been reversed.

Li Ming originally wanted to ask, but seeing that Wang Mingyang didn't speak, he wisely chose to sit on the sidelines.

"The copper precipitation was severe in the control group, and the iron content was also greatly reduced. It's a bit strange."

Wang Mingyang also had doubts on his face.

"Severe copper precipitation means that the ion receiving capacity of the positive electrode material is greatly reduced. As for the reduction in iron content, it should be that one of the temperature control points of the electrolyte is not in place."

Jiang Ming explained.

Seeing these two phenomena, combined with the test data, Jiang Ming had a rough idea.The problem should be in the production process, and there is no problem with the design principle.

After all, there is no problem with the set of control samples I made.

As for specific problems, we have to go to the site to check.

Good guy, that's all Wang Mingyang can say. Jiang Ming is not an easy guy. He has analyzed the problem in such a short period of time. He is a bit strong.

"Director Li, please arrange for someone to restart the production line, step by step production, I will check step by step."

Jiang Ming said to Li Ming.

"You mean that there is a problem with the production process, but we have checked many times and found no problem?"

Li Ming understood Jiang Ming's thoughts and said nervously.If they didn't find out about their own internal production process problems, they would be happy.

After all, according to Li Ming's comprehensive analysis, the problem most likely lies in the battery design itself.

"Not necessarily, Director Li, don't be nervous."

Seeing Li Ming's nervous expression, Jiang Ming felt happy.

After all, when did you see Li Ming with such an expression?

"Well, it's getting late, let's go to dinner. I will arrange people to prepare materials and equipment at the same time. In the afternoon, restart the sample line."

Li Ming looked at it and said.

"No problem, but we need the same equipment and personnel, and try to keep everything else the same as before."

Jiang Ming exhorted specifically.

Jiang Ming could understand Li Ming's appointment in the afternoon.

The changeover of a production line is not that simple. Generally speaking, it takes at least half a day for the changeover.

This involves a series of work such as material preparation, pre-job training for personnel, verification of the first sample, and change of tooling.

The scene of automatic switching with a single voice does not exist for the lithium battery industry.

Even in the passenger car production line with the highest degree of automation, changing compatible models requires a large number of equipment conversions, and the switching of related molds can be said to be quite cumbersome.

Originally, according to Jiang Ming's idea, a simple meal at noon would be the end of the matter, but Li Ming obviously would not neglect the technical experts, especially Professor Wang Mingyang.

Looking at the dishes, pans and soup in front of him, Jiang Ming was speechless. Dozens of dishes, just the three of them, can they finish it?

Wang Mingyang ate very little, and basically discussed technical issues with Jiang Ming the whole time.

Throughout the morning, Professor Wang Mingyang admired Jiang Ming's skills.

Wang Mingyang knew that he had missed this opportunity, and he didn't know when he would meet him next time, so he asked whenever he had the opportunity.

Jiang Ming liked Wang Mingyang's attitude from the bottom of his heart.

After all, through the conversation with Wang Mingyang, Jiang Ming has a better understanding of the entire industry.

Jiang Ming and Wang Mingyang had a great time interacting, but because of Li Ming who was next to him, he couldn't get in a word.

In the end, Li Ming had given up the chance to interrupt and concentrated on eating.

The afternoon time came quickly and it was time to go to the scene.

Jiang Ming thought it was just himself, Professor Wang, and Li Ming, but unexpectedly, the main leaders in charge of technology all came.

There are ministers, supervisors, and subordinate senior engineers, dozens of them.

Seeing so many people, Jiang Ming frowned.

"Director Li, why are there so many people?"

Jiang Ming asked.

"It's like this. At noon, I briefly talked to the leader in charge of craftsmanship. It may be a problem with craftsmanship. They attach great importance to this issue and want to go to the site with you to have a look."

"Don't worry, they promised me that they will not delay your work."

Li Ming explained.

"That's all right, watch more, talk less, and keep quiet."

Jiang Ming exhorted.

Hearing Jiang Ming's words, the people in charge of the craftsmanship on site were about to explode. When did they, senior engineers and supervisors, get treated like this?

They are almost regarded as interns. You must know that they all have decades of experience in this industry. When have they been treated like this?
Talk less, keep quiet, and make sure this is not a word to coax a child?Still need you to teach?

Originally, they were dissatisfied with Jiang Ming's suspicion that it might be a matter of craftsmanship, but now they heard Jiang Ming's words, and the anger in their hearts can be imagined.

If you can't find the problem later, you will be ashamed!
At this moment, the craftsmen didn't dare to say anything, they could only suppress their dissatisfaction in their hearts, and waited to see Jiang Ming's jokes.

Jiang Ming himself had a problem with so many people following him. As for the dissatisfaction of the crowd, that was their business and had nothing to do with him.

As for Wang Mingyang, seeing so many people following him, he was also a little dissatisfied that he couldn't have further technical discussions with Jiang Ming.

But after all, this is the person arranged by Li Ming, and he is not very good at saying anything.

The production line has started, the first sample has been verified, and formal production can begin.

Ingredients, coating, pole piece dividing, rolling, drying, and winding.
Looking at the process one by one, Jiang Ming stopped and walked, and there was no expression on his face.

The people in the craft department followed the whole process, trying to find some problems, but in the end, dozens of people couldn't find the problem.

Of course, it cannot be said that there are no problems. All they find are small problems. In their view, they have little impact.

The others were far away from Jiang Ming, but Li Ming was on Jiang Ming's left, but he was always watching Jiang Ming.

Others saw that Jiang Ming's expression did not change, but Li Ming found that Jiang Ming's expression changed several times during the whole process.

"Could it be that there is really a problem with the craftsmanship?"

Li Ming began to feel uneasy.

It's just that these few processes seem to be normal. They are all routine operations, and they are not even key positions.

If there is no problem, why did Jiang Ming stay at these points for the longest time, and his expression also changed? This is a bit wrong.

"Director Li, it's alright."

Jiang Ming signaled to Li Ming that there is no need to continue the production.

Li Ming also stopped the production line as soon as possible, which can be regarded as saving some costs. Although the start-up is not conspicuous, in such a short period of time, with the addition of artificial materials, there is no one that cannot be produced by hundreds of thousands.

Seeing Jiang Ming's determined expression, Li Ming felt even more uneasy.

"Brother Jiang, did you find anything?"

Jiang Ming followed Li Ming on the way to the meeting room, Wang Mingyang asked in a low voice.

"The problem has been locked, it is the problem of the production process."

Jiang clearly believed.

"Oh."

Wang Mingyang had nothing to say.If other people said it, Wang Mingyang might not believe it, but about Jiang Ming, Wang Mingyang was not sure.

Just now when the production line started, Wang Mingyang watched the whole process carefully, but he didn't find any problems.

Although Wang Mingyang may not be so proficient in the details of the process, but the basic principles are clear. In his opinion, Baineng's production process is relatively advanced.

For the control points of the process, the distinction is relatively clear.

The only problem may be that this is a manual line with a relatively low degree of automation.

There is no way to do this, after all, this is just a sample line, and it needs to be used for many cell models, so the degree of automation cannot be high.

After the battery sample is tested, it will be put on the automated production line. I believe that the consistency of the battery will be greatly improved.

In the meeting room, there were only Jiang Ming and Li Ming, because the content of the next discussion was private.

"Director Li, the problem has been locked, let's talk about the compensation."

Jiang Ming went straight to the opening of the topic.

"Wait a minute, how can I be sure that you have found the problem and are sure that you can solve it."

Li Ming frowned. Sure enough, his guess came true. It was really a matter of craftsmanship.

"After we finish talking, I'll tell you that you can verify that what I said is true."

Jiang Ming is very confident.

"Is it really a matter of craftsmanship?"

"Yes, I'm sure."

Hey, hearing Jiang Ming's affirmative answer, Li Ming felt a burst of emotion in his heart.

"How much do you want in terms of compensation?"

The matter has come to this point, Li Ming knows that the talk must go on, for each other.

Hearing Li Ming's words, Jiang Ming was stunned. To be honest, Jiang Ming didn't know how much he wanted.

After all, Jiang Ming had never done this kind of business before, and he had been thinking about asking Baineng for more money, but when he really spoke, he had no idea.

Although he had no idea, he couldn't show his secrets in front of Li Ming. Jiang Ming acted like he was thinking.

"Think about it first, and I'll come back later."

Seeing that Jiang Ming was thinking, Li Ming was overjoyed, so he said so.

Afterwards, after Li Ming left the meeting room, he quickly contacted the manager of the process department and asked him to check the production process as soon as possible.

According to Li Ming's thinking, it has now been determined that it is a problem with the production process, and with several key points of doubt, the difficulty of investigation is much less.

If the people in the craft department can check it out, then Jiang Ming will have nothing to do.

After receiving Li Ming's call, the manager of the craft department was also in high spirits. With such clear instructions, the problem became much simpler.

Subsequently, the main engineer of the process department began to search for problems on the sample line.
