For the gift, start research and development of graphene batteries

Chapter 17 Project Progress in Other Groups
The next day, Jiang Ming got up early and came to the company to observe the progress of the project.

In fact, Jiang Ming is also very curious about the effect of a battery made of graphene negative electrode material.

Although there is no problem in principle, Jiang Ming can't guarantee that the finished product will not come out.

It's very exciting to think about it. After all, this is Jiang Ming's first independent design of a battery, and success or failure depends on it.

When Jiang Ming came to the office, Song Zhiyi had already arrived, which was very rare.

In fact, Song Zhiyi has been here for more than an hour. In order to make a new type of battery, Song Zhiyi is also busy.

I also worked overtime yesterday, bringing out all the things I needed, and waiting for the actual production today.

At the same time, in order to ensure that the sample line can be launched today, Song Zhiyi did not ask Su Lingjuan to coordinate, but communicated in person.

It was very late to get everything done.

Jiang Ming and Song Zhiyi came to the sample room to check the progress of the launch.

In Baineng, the sample line is independent and is a small production line.From the front-end ingredients to the final formation, there are independent equipment.

And it is equipped with special workers to cooperate with engineers to make sample batteries.

The 500Wh/kg battery adopts the technical route of the soft case, in order to reduce the weight of the case as much as possible and increase the energy density.

In fact, several other groups have the same technical line in terms of shell selection.

The production steps of lithium batteries are very complicated, and there are hundreds of kinds of equipment involved.There are countless control points.

It takes about five days from the time the materials are put into production to the final product.

Among them, ingredients and final formation are the most time consuming.

Jiang Ming looked at the positive and negative electrode materials, put them into different tanks, and then added various additives.

Afterwards, the tank is sealed, and the vacuuming process is started, followed by stirring evenly.

This process is simple to say, it is similar to the process of making noodles.

But it is not easy to reconcile this side.It involves the ratio of materials, additives, vacuum and temperature.

An error in any of these parameters may lead to the scrapping of raw materials.

The value of Jiang Ming's can of materials may not be very high.

In the mass production process, it is full-speed production, and a can of materials costs hundreds of thousands.

If this is accidentally abolished, the loss will be great.

Although I know that the workers on the sample line are skilled workers, and Song Zhiyi is watching, there shouldn't be any problems.

But Jiang Ming still didn't leave, and planned to follow him all the way.

In order to keep an eye on the samples, Jiang Ming asked Li Ming to leave, and the project meeting was closed.

Li Ming had no opinion on Jiang Ming not participating in the project meeting.

After all, Li Ming is the clearest about the research difficulty of the 2 groups.

In Li Ming's expectation, the second team may still be checking information and finalizing the plan.If you want to come up with a decent plan, the three people in Group 2 will be busy.

If Jiang Ming was really required to report the progress, it would also be a joke for the other groups.

For this reason, Li Ming specifically asked Jiang Ming not to attend the project meeting, and if there was any major progress, just copy the email to her.

Jiang Ming also breathed a sigh of relief when he saw the message sent by Li Ming.Jiang Ming felt very relaxed because he didn't have to waste his tense time in boring meetings.

It’s just what Li Ming said: reporting on major progress, how to define it?
Do you want to report to Li Ming that now the two groups have started to make samples?
Not even a sample has been made, so this shouldn't be considered a major development, right?
Wait for the samples to come out and have preliminary data, and then report!
In his heart, Jiang Ming decided this matter happily.

After all, in Jiang Ming's opinion, he has mastered the full version of graphene himself. In order to cope with the company, the castrated version of the battery is nothing special. We will wait until the samples are released.

In the conference room, Li Ming was listening to the other three groups reporting their progress.

It's just that the more I listened, the more I felt that something was wrong. Li Ming's face became gloomy from the expectation before.

Li Ming was a little depressed. The progress of the three groups was not good, and the actual effect was worse than she expected. According to this progress, there was no way to explain it to the company.

Baineng has more than one R&D department, and the different R&D departments are all in a competitive relationship.

It is said that several other works have made great progress, but only the two of them have made such slow progress.

How could Li Ming, who had always been strong-willed, endure this.

Besides, Li Ming is very clear about Baineng's emphasis on this project.If he messes up this time, his position will come to an end.

Thinking of this, Li Ming's face turned livid:
"I said Zhang Rui, what's the situation in your group 1? How come you haven't come up with a ready-made plan yet?"

Hearing Li Ming's words, the man named Zhang Rui also looked terrified.

After all, their group 1 plan is ready-made, as long as they continue to optimize and improve it.

But the project is easy, which means that there is little room for improvement, and it is even more difficult to make a qualitative breakthrough.

In order to improve the energy density, a group of them and application engineers are working overtime to design, and only they can know the hard work.

It's just hard work, but the effect of improvement is limited.According to their design, the energy density of the battery can be increased to 250 at most, which is far from the company's goal.

It's just that Zhang Rui didn't have the face to explain to the company that he had been promoted to this level, so he didn't show it.

"Sister Ming, we actually have a plan, but the improvement is limited, so we didn't show it."

Seeing Li Ming get angry, Zhang Rui quickly explained.

"How much is it raised to?"

Hearing that there was already a plan, Li Ming's expression softened a little, and he asked.

"250!"

"250, 250, you have the nerve to mention this plan?!"

Li Ming heard that the energy density was only increased to 250, which was a burst of anger. After nearly a week of work, it has been increased by this point. How can it not be annoying!

"Liu Zhiwei, what about your 4th group? I heard that you have invited Professor Ouyang here. You should have a plan, right?"

Li Ming calmed down and said to a middle-aged man beside him.

"Sister Ming, it's like this. We have done a lot of work in the past week. Through communication with Professor Ouyang, we have initially determined three plans, specifically."

Liu Zhiwei, the leader of Group 4, showed the corresponding report while talking.

It can be seen that Liu Zhiwei is still well prepared.

The entire report, from project approval, to scheme design, to experimental verification, has relatively complete relevant content.

But Li Ming still frowned when he looked at the contents of the report, and then said:

"According to the first one, the design concept of large polymers, is there any way to increase the energy density?"
