For the gift, start research and development of graphene batteries

Chapter 18 Company-Level Project Promotion Meeting
"I'm afraid not. According to the current plan, it has already exceeded 20% of the standard value. If it is increased, its stability cannot be guaranteed."

Li Ming shook his head as he looked at the figure of 300Wh/kg in the plan.

Although the value of 300 has improved a lot compared to before, it is far from enough for this project.

But Li Ming also knew that if he wanted to improve further, his safety could not be guaranteed.This in itself is a way to sacrifice security to improve performance, and it can only be a compromise.

"Where are you three groups, Hu Sheng?"

"We communicated with the supplier and received the latest material, which is currently being verified. According to the information obtained from the supplier, the latest material has reached the value of 300, which is the limit."

"300Wh/kg is far from enough!"

Well, almost new materials are at this level, as expected by Li Ming.

If you can combine several solutions, how much can you improve?

Thoughts swirled in Li Ming's mind, and he immediately figured out that this plan should be feasible, and further room for improvement could be tapped.

"In this way, you conduct a joint design of 3 groups and 4 groups, use the material with the highest energy density, and then use the 4 groups of large polymer solutions to see how much you can achieve."

Hearing Li Ming's arrangement, Liu Zhiwei and Hu Sheng's eyes lit up. This is a way of thinking.

On the basis of the stagnation of the current plan, it can be tried.

Afterwards, the project will end, and groups 3 and 4 will carry out joint development according to Li Ming's arrangement.

The days passed quickly, and five days passed in a blink of an eye.

Jiang Ming looked at the samples on the desk with a look of joy on his face.

Next to the battery sample is a capacity test report.

Looking at the figure of 580Wh/kg in the test report, Jiang Ming was also very happy.

Hard work pays off, after so many days of design, the battery cell is finally made, and the preliminary test has reached the design standard.

To verify the performance of a cell, a lot of steps are actually required.

It's not like taking it to the instrument and reading it with the device.

Take the simplest capacity test, it also takes 3 days to test, after 9 rounds.

Not to mention high temperature cycle, low temperature cycle, capacity fading, these test items in units of months.

If one of the items fails, the previous design may have to be overthrown and restarted.The risks faced in it can only be known by insiders.

Jiang Ming was deeply aware of the hardships involved, and looked at the samples in front of him with a lot of emotion.

Song Zhiyi looked at the experiment report. Although he arranged the test, the shock in his heart could not be calmed down for a long time.

No one thought that the company-level research and development project was completed by the three of them, and it was done in such a short period of time.

Moreover, Jiang Ming, a technician, completed most of the designs, which is unbelievable when you think about it.

Song Zhiyi could imagine that the success of this project would bring about huge changes to everyone.

To say it is an epoch-making achievement may be a bit too much.But as Baineng's core product, there is no problem.

Jiang Ming looked at the test report and the report written by Su Lingjuan before, suppressed the joy in his heart, and prepared to reorganize the corresponding reports and data and send them to Li Ming by email.

After all, Li Ming said before that if there is any major progress, just email her.

The samples came out, and the test data came out. This should be a major progress, right?
While Jiang Ming and Song Zhiyi were excited about the success of the sample, Li Ming was in trouble.

Today is the time for the company-level project promotion meeting. As the supervisor of the second R&D department, Li Ming will introduce the progress of the battery cell development of the second R&D department in the company-level project meeting.

Seeing it together, there are other directors of the R & D department.

The focus of this meeting is to report the development progress of 500Wh/kg high-performance lithium battery cells.

As a company-level project, Mr. Guo, the executive vice president of Baineng Company, will also participate in this meeting.

It is enough to see Baineng's emphasis on high-performance lithium batteries.

Li Ming was quite happy when he heard that President Guo was attending the meeting. After all, he had an extra opportunity to show off.Moreover, after my own support last time, the 3 groups and 4 groups combined to re-design the plan.

After confirmation, the energy density of the newly designed battery cell is expected to reach 320Wh/kg.

According to Li Ming's estimation, the energy density of 320Wh/kg should be among the best in Baineng Company.

As a result, when the project meeting was held, Li Ming was dumbfounded.

Because Li Ming found out that he seemed to be heading in the wrong direction.In other words, Li Ming didn't pay enough attention to company-level projects.

At the meeting, the director of the first R&D department introduced the newly developed battery, lithium-sulfur battery.

According to the director of the first department, if this lithium-sulfur battery can be successfully developed, its limit energy density is expected to be close to 500Wh/kg.

Of course, this kind of lithium battery is very difficult to develop and involves many technologies, so it is difficult to develop it successfully.

However, the director of the first department said that a university has been found to cooperate in development through school-enterprise cooperation.

It is expected that the development progress will be much faster.

At present, the preliminary scheme design has been carried out, and the cooperation with universities is also advancing in an orderly manner.

According to the development progress of the project, it is estimated that within 6 months, the preliminary scheme design will be completed.

At the same time, advance according to the time of 9 months, and strive to come up with the first sample.

Confident eyes, refined reports, detailed data, and precise project promotion plans have won the appreciation of the company's leaders.

Although the total time of the project is relatively long, Mr. Guo still gave a high degree of affirmation to the work done in the first part.

Li Ming was dumbfounded after watching the progress of the work of the first part.

It's not that the work of the first part is bad, it's so good that Li Ming can't talk about the work of the second part.

As the saying goes, people are more popular than people, and this is the situation now, and Li Ming feels bad.

Next, the director of the third department showed the project promotion plan, which is lithium-air battery.

The four projects are solid-state batteries, and the five projects are lithium-aluminum batteries.

At the end, Li Ming's face turned green.

Because Li Ming was the last one to come in, today Li Ming is sitting in the last position. Correspondingly, the second part will be the last to show the progress of the project.

It can be seen that Mr. Guo is very happy today.

Because Mr. Guo has seen many novel batteries and many products that may bring about industrial breakthroughs.

Although it is impossible for these products to be mass-produced, one of them may have a major breakthrough and become the company's flagship product.

Who said that Baineng's basic research and development is weak, and who said that Baineng has no core products. At this meeting, Mr. Guo saw Baineng's R&D potential and future product planning.
