For the gift, start research and development of graphene batteries

Chapter 65

"Mr. Jiang, that's it. We designed the diaphragm according to the design method, but the porosity of the diaphragm has not been raised. Generally, the porosity of the diaphragm should reach about 40%. This time the target is higher, 60% But at present, it seems that the porosity is only more than 20%, and this kind of porosity is completely unapplicable.”

Yao Lei showed the report, and then pointed out the key points of the problem to Jiang Ming.

To be honest, there was no way to invite Jiang Ming over.

It should be said that Yunjie Technology needs technology and equipment, but they are helpless in the face of this problem. They have no choice but to report this problem.

"In this way, let's talk about the current method of porosity formation."

Jiang Ming didn't respond directly, but asked Yao Lei to explain.

"According to our process, using inert gas neon, at a high temperature of 800 ° C, based on bluestone, the copper ions in bluestone are brominated into free copper, and then pass through the diaphragm forming chamber to form a micropores."

Yao Lei explained in this way.

"Then do you know why the high temperature is 800°C?"

Jiang Ming continued to ask.

"This"

Yao Lei was dumbfounded. Is there anything special about this temperature? It seems that everyone in the industry does this.

Moreover, they did this by referring to foreign diaphragm factories and making comparisons.In the end, it really worked.As for why this is done, no one pays attention.

Everyone only knows that if you don't do this, the yield rate of the diaphragm will fluctuate more frequently.

Could it be that there is some doorway in it.

"Boss Jiang, what's wrong?"

Yao Lei asked tentatively.

"Wrong, wrong in principle, only know the appearance, not the meaning."

Jiang Ming said with emotion.

"President Jiang, please clarify."

Yao Lei still didn't understand what Jiang Ming meant, so he asked directly.

"How should I put it, the temperature of 800°C is not necessary, this temperature needs to be adjusted."

Jiang Ming said so.

What, no way, the temperature can be adjusted, Yao Lei was stunned, after so many years of working as a diaphragm, he heard such a statement today.

If someone else had said it, Yao Lei might have started spraying it long ago, but it was pointed out by Jiang Ming, and it was said by the chief engineer of the carbon-based battery, which made Yao Lei dare not make mistakes.

"Mr. Jiang, what's the situation? As far as I know, not only our domestic companies, but also foreign companies have this temperature. It's not that we didn't study the influence of this temperature on the diaphragm, but we did. We found that at this temperature, The yield rate is the highest."

Yao Lei explained.

"The temperature of 800°C is based on the bromide value of copper. As long as the bromide value can reach a certain level, you can be at room temperature."

Jiang Ming said.

This!
Hearing Jiang Ming's explanation, Yao Lei felt that he was ignorant, and there was even an indicator of bromination value, which no one had heard of before.

But this explanation, understood in the first day of junior high school, feels so reasonable.

"However, foreign counterparts also use this temperature value, and the yield rate of the product is very high."

No, it's not just us doing this, everyone is like this, and there is no problem, Yao Lei suddenly reacted, and then said.

"Then have you ever reflected on why the yield rate of others is so much higher than yours with the same process?"

Jiang Ming didn't rush to answer, but asked like this.

"Maybe there is a problem with our raw materials, or there are differences in some processes in the production process."

Yao Lei hesitated for a long time, and finally said this.

"Half of the answers."

Jiang Ming replied.

amount.

Hearing that the answer was half correct, Yao Lei was also taken aback, but he didn't expect to get it right.

"Compared with foreign countries, our raw materials are inferior. As a result, with the same process, our products will be inferior. Whether it is the yield rate or the performance of the final product."

"But what does that have to do with temperature?"

Yao Lei couldn't help asking.

"As I said before, the purpose of temperature control is actually for the bromination value. If the raw materials are relatively standard, set a temperature value, and then at this temperature value, the bromination value will not be low, and the corresponding good products will also have ensure."

"Foreign raw materials have high standards. Correspondingly, it is understandable to set a rigid temperature value. However, our Xia country has too many sources of raw materials, and a single fixed temperature value is not enough to increase the bromination value."

"You mean to use the bromide value to infer the temperature value and use the bromide value as a key point for control?"

After Jiang Ming's explanation, Yao Lei understood a little bit, so he asked.

"Right, that is it."

"But how do you measure the bromide value? It hasn't been done before? There is no standard, and there is no such thing."

Yao Lei asked.

Like this, like this.

Jiang Ming didn't know much about these professional equipment.Jiang Ming could only describe the key points in a sketchy way, and let Yao Lei and the others study it.

Large companies like Yunjie Technology have professional equipment engineers to serve them.

Some of these engineers are responsible for the daily maintenance of equipment, and some are inclined to craftsmanship.

It specializes in work fixtures and some special equipment.

The determination of the bromination value requires special equipment.

Yao Lei wrote down what Jiang Ming said, and then summoned engineers to design the equipment Jiang Ming said.

As for the standard, although Jiang Ming didn't say it, but now that he understands the truth, it can be inferred through verification.

For example, bromide value, the higher the better.

But the higher it is, it means that other conditions have to be improved, and whether the temperature of the heating furnace can withstand it will have to be considered again.

Now that the role of bromide value is known, the next step is easy.

Soon, Yao Lei had already arranged for this work, and he wanted to design the finished product as quickly as possible, and then verify it.

After that, Jiang Ming didn't have anything else to do, and Jiang Ming was rarely at leisure, busy with his own affairs.

After experiencing Yanyan's incident, Jiang Ming felt that he had to hurry up on his training, otherwise it would be too embarrassing for a female doll to subdue him easily.

Of course, the biggest problem is that Jiang Ming feels that his safety is not guaranteed.

As for Peiyuan Pill, Jiang Ming has been taking it regularly, but because Jiang Ming is not exercising, the effect of the medicine is not very good, Jiang Ming also took advantage of this opportunity to exercise.

Taking advantage of this gap, Jiang Ming also studied the information on autopilot technology given by Qin Ruya.

Jiang Ming has been studying autonomous driving technology for a long time. It is a rare opportunity to participate in their project this time. Jiang Ming does not want to miss this opportunity.

Moreover, the knowledge level of autonomous driving technology is not far from 100%. Jiang Ming hopes that through this project, it will be pushed to a small success in one fell swoop.In this case, the inheritance of knowledge will be logical.

According to the project information given by Qin Ruya, this time it is necessary to add an automatic driving system to the newly added shuttle bus in the Kyoto City Industrial Park, which still has a lot of difficulty.

Although there are automatic driving systems in some passenger cars, how to say it should be called assisted driving technology, which still requires human participation.

Although the shuttle bus is only in the industrial park, it is also a fully automatic driving technology.

This project can be regarded as a pilot project, and if successful, it may be extended to the whole country.

There are several main points to choose from the industrial park:

1. The flow of people in the industrial park is relatively small, and the environment is not that complicated, and it is relatively simple.

2. The traffic markings and other facilities in the industrial park are relatively clear, which is conducive to the system's discrimination of the environment.

Jiang Ming thought about it again, and it feels quite complicated, the most important thing is the part about visual perception.

Since it has a demonstration nature, it will be extended to the whole country in the future. The traditional method of simply relying on lidar may not be very suitable.

This time it is estimated that pure visual sensing will be used, and there will be many technical difficulties in the process.

In addition, it is about the software decision logic of the driving system, which is also a difficulty.

A simple question is which one should the system choose to collide with when faced with a collision, the logic of which is difficult to understand.Unless it is from the very beginning, it is guaranteed that the vehicle will not collide.

However, scratches and collisions of vehicles are inevitable. In this case, the judgment of the driving system is necessary.

The hardware aspect is not a big problem, the most important thing is the software aspect, especially the system logic aspect, which is the top priority.

Thinking about it this way, it is still very challenging, and Jiang Ming is also very interested in it.When the matter of carbon-based batteries is almost done, I still have to go to Kyoto to get this project done.

Yunjie Technology, after three days of experiments, finally confirmed that the theory of bromination value mentioned by Jiang Ming is correct. According to the bromination value, dynamically adjust the temperature, Yunjie Technology finally solved the technical difficulties faced by the diaphragm.

And after this breakthrough, Yunjie Technology has improved the quality control of the diaphragm to a higher level.

Everyone highly admired Jiang Ming's technology.

After all, it was said that Jiang Ming was the chief engineer, but this was appointed by Mr. Wang after all, and the people who knew Jiang Ming's strong technology were limited to those who had participated in the seminar before.

Only by solving technical difficulties can the technicians present be able to intuitively feel Jiang Ming's superb technical level.

Declining Yunjie Technology's plan to entertain him, Jiang Ming rushed to Jianglin non-stop.This time, it was not a problem with the carbon-based battery, but Lin Wanqing called, saying it was a problem with the healing powder.

Lin Wanqing had told Jiang Ming before that there was a problem with the spokesperson of Yufu Powder, and Qingshuiyan was originally planned, but because Baijie added hormones, Qingshuiyan also distrusted Meiya International.

The spokesperson had already been decided to be Qing Shuiyan, and the results had been published. Now that she is changing, it will have a huge impact on products like Meiya International and Healing Powder.

Based on this, Meiya International invited Qing Shuiyan to come to Jianglin, and then asked Jiang Ming, as a developer, to give Qing Shuiyan a good talk, trying to dispel Qing Shuiyan's concerns.

Qing Shuiyan's team has cooperated with Meiya International for many years, and they didn't want to make matters worse, so they agreed to Meiya International's request.

"That's it, Sister Liu, look at our products, which are completely herbal essences, and we have also fully disclosed the formula of the materials. Moreover, after market verification, we have not received a single complaint from customers. This is enough to prove , Healing Powder is safe and reliable.”

Before Jiang Ming entered the meeting room of Meiya International, he heard Lin Wanqing's words.

It can be heard that Lin Wanqing has lowered her status to a very low level and intends to beg the other party.

"Manager Lin, I understand what you said, but what should I say, public opinion is beyond our control. Once things escalate, it will cause great damage to Qing Shuiyan."

The gentle voice of a middle-aged woman came. Although her words were gentle, the meaning she expressed was very strong.

"Sister Liu, we have cooperated for many years, you know the reputation of our Meiya International, can't you talk about it again?"

Lin Wanqing was a little anxious and said this.

"Manager Lin, I've made it very clear. Qing Shuiyan can't bear the result of the fermentation of the problem. You should find someone else."

The middle-aged woman continued.

"Yanyan, let's go!"

While talking, the middle-aged woman pulled the woman next to her to go out.

Jiang Ming was stunned. The talks between the two sides collapsed. Isn't this too fast?
Lin Wanqing's calling Jiang Ming over was actually a pretense, using the identity of Jiang Ming's developer to invite Qing Shuiyan's team over.

The two parties meet in person, so that they can communicate more directly.

It's just that Lin Wanqing didn't expect that Qing Shuiyan's team would be so resolute, and she seemed a little dismissive of the various plans Lin Wanqing proposed.

The negotiation just now was actually at the last juncture. The manager named Sister Liu still rejected Lin Wanqing's proposal.

Seeing that the negotiation had no results, how could Lin Wanqing not be in a hurry.

"Jiang Ming, you are here, please introduce our products to Sister Liu and the others."

After seeing Jiang Ming coming, Lin Wanqing was overjoyed and said that Jiang Ming came just in time, so she had the opportunity to keep Qing Shuiyan and the others to continue the discussion.

As for whether we can talk about success in the future, I don't care about it, at least we can't let people go straight away.

The manager named Sister Liu didn't talk to Lin Wanqing. As a manager, Liu Linqing had seen too much of this method. It was nothing more than delaying a little more time so that she could find a chance for herself.

It's just that Liu Linqing knew that it was futile for the other party to do so.

Not to mention that there is a problem with Yuling powder in the market, and it is rumored that there are additives.Even recently, Qing Shuiyan's condition has problems, and Qing Shuiyan is not in the mood to perform her duties as a spokesperson.

This time I had the opportunity to come here, and I also considered that there would be opportunities for cooperation between the two parties in the future, so I brought the reluctant Qing Shuiyan to Jianglin.

Qing Shuiyan was extremely repulsed by this trip, as soon as she landed, she hurried back to the magic capital.Although she was dragged to Qingya International, Qing Shuiyan didn't say a word except for saying hello at the beginning.

As Qing Shuiyan's aunt Qing, how could Liu Linqing not know about this kind of behavior.

Based on this, Liu Linqing refused so simply.

Her own niece, Liu Linqing, knows it very well, and returning to the magic capital as soon as possible is the main task.
