She originally thought that this son-in-law was a more or less reliable person, although she didn't particularly like it, but she could pinch her nose and admit it.

No matter how many shortcomings he has, it's not a big problem.

As long as his daughter likes it, as long as he can make her happy, it doesn't matter if he has money or not, whether he has the ability or not.

But now it seems that some things in life are destined to fail.

"Shen Chong, you make it clear, this is the research result of a team of hundreds of people who spent several years of hard work and hundreds of millions of dollars, which represents the next important development direction of China's battery energy industry and is an important policy for China to carry out technological competition with countries around the world! Why do you say no with empty words and white teeth! If you're at this level, then I'm afraid I'll really have to reconsider the matter between you and Zhishu. ”

The atmosphere in the study suddenly became heavy, and Shen Chong, who was in a hurry, instantly sobered up.

Not good!

I didn't expect to be careful and careful, but I still poked out the basket.

He was a little embarrassed, not long ago, he personally promised the child's mother that he would have to treat his mother-in-law more, and endure more.

I never thought that I would give up all my efforts for a while, forget it, and let it go.

He apologized with an embarrassed smile, "Auntie, I'm sorry, I'm talking nonsense." Don't care, sorry sorry. ”

After saying that, he wanted to slip away, but Qin Yun was really angry, and he didn't plan to let go of this arrogant person.

Although she just said angry words, she wouldn't really beat the mandarin duck on this matter, and she couldn't beat it.

But the mother-in-law felt that she should teach this son-in-law a good lesson to her son-in-law who was indiscriminately pointing at him with some talent, so as to save a similar situation in the future.

Qin Yun has dealt with many crazy people, and when she was young, she offended people because of academic battles, and she has her own views on genius.

Properly suppressing geniuses can allow him to learn to be low-key and humble in the rest of his life, and to be able to really calm down and do things.

"Shen Chong, stop."

Qin Yun's calm voice sounded behind Shen Chong.

He paused.

Alas, he couldn't leave, he turned around and gave his hands again and again, "Auntie, I was wrong, I was really wrong." You can just take what I just said as a gust of wind, and you can pass it with a breath. ”

Qin Yun shook his head, moved the chair to the side slightly, and patted another stool, "Since you said that there is a problem with the material of the polymer separator, then I am really interested in hearing your opinion." ”

"How can there be any high opinions, it's all nonsense."

Shen Chong's vest was a little cold.

The mother-in-law suddenly calmed down after her anger, which was obviously the calm before the storm.

The more calm she is, the more terrifying she looks, and she can bring a strong sense of oppression.

The mother-in-law's emotional regulation and camouflage ability are exactly the same as the child's mother!

Lao Lin also learned from her!

"I don't think you're. You didn't mention the electrode, electrolyte and metal shell coating, and you didn't pick the discharge stability and voltage of the battery. As soon as you come to focus on the polymer diaphragm, it means that you have an idea in your heart. How did you come up with the two-year threshold, let's talk about it. ”

Her tone was calm, but there was no room for negotiation.

Her subtext is, if you don't say a door, then don't think about leaving today!

Shen Chong sighed secretly, yes, there is no way.

There is a road in heaven that you don't take, and there is no door to hell, you have to break in, take it!

He stepped forward with a light cough, "Then I'll talk a little bit about it?" ”

Qin Yun suddenly felt that this son-in-law's momentum was slightly different from before, and his heart was secretly dark, he was really as arrogant as rumored.

What an arrogant late student!

"Okay, I'll hear you."

She said.

Shen Chong smiled, "This is a woven diaphragm based on polypropylene, right?" ”

"Yes."

Shen Chong said again: "Polypropylene separator, also known as PP separator. At present, the best in the world are island countries and the United States. Auntie, do you hope that the company you invested in will break the monopoly of other countries in the field of separators while conquering the technology of lithium iron phosphate batteries? ”

Qin Yun was slightly surprised when she saw that he had said the point, and nodded: "Yes, although our country is strong now, it has won and lost with other countries in many fields. For battery separators alone, we will be made billions of profits every year. At present, we can only replace low-end products, and high-end products are extremely dependent on imports. ”

Shen Chong continued: "Then I can only say that Auntie, you are thinking too much. The next step of this project should be to improve the weaving, synthesis and purification process to try to improve the stability and mechanical properties of PP separators, right? ”

Qin Yun was really shocked this time.

The key part of the paper she just read did mention the direction of research and investment in this step.

But Shen Chong didn't see that part of the paper.

In addition, this matter is a top secret, and no third person in the world knows about it except her students and herself!

"How do you know?"

As soon as Shen Chong looked at Qin Yun's face, he knew that he was completely right.

The bankrupt enterprise in the previous life knelt in this direction.

"It's useless, it's not innovative, no matter how much it is improved, it can't pass the two-year ceiling! The diaphragm made by this weaving process of Auntie lacks inert molecular coverage on the surface, and the alkaline corrosion resistance can only be increased by 50% at most! In addition, China's land is vast, the temperature difference between the north and the south is huge, the temperature in the north is low in winter, the low temperature resistance of PP diaphragm is very poor, in the northeast of the country to say two years, one year will have to be brittle cracking, along this process, from the beginning of the wrong road, the deeper will only be wrong! ”

Since the mother-in-law sincerely begged for a slap in the face, Brother Shen decided to fulfill it.

The so-called easy nature of the country is difficult to change, some things really can't be helped, once his engine is ignited, he can't brake the car.

Qin Yun argued angrily, "Your inference is completely groundless, how can you make a conclusion without the support of experimental data?" ”

Shen Chong smiled proudly, ignored his mother-in-law's question, and said to himself: "At present, the main emerging market in the domestic battery industry is new energy vehicles. So let me ask you a rhetorical question, putting aside the point of corrosion resistance, just talking about low temperature. In the future, the new energy vehicle manufacturers that use your batteries will have to only sell in the south and not in the north? Or do you have to make it impossible for consumers to drive to the north? Can this product be sold? Is there any value in doing a project without a market? ”

Qin Yun stood up from the chair, "I asked where your conclusion came from, don't talk about other places!" ”

Shen Chong took the pen and paper and sighed, "Okay, let's analyze it." ”

After speaking, he began to write and draw on the paper, first writing out the molecular formula of the main material of the polypropylene separator, and then writing the molecular formula of the excipients.

"The result of this weaving process is this ......"

"Under alkaline conditions, the process of potential transfer is ......"

"After the battery is fully charged, all the lithium ions are on this side, and the electrons will continue to hit the other side, changing the electricity price in the polymeric film, no matter how small the probability of a reaction is, it is still unavoidable."

"To sum up, the weaving process like the current one, no matter how you change it, it's useless!"

Qin Yun didn't believe it at first, snatched the full amount of scratch paper from Shen Chong's hand, and read it all the way at a very fast speed.

The more she looked at it, the more frightened she became, and the more she looked at it, the more unbelievable it became.

Although this is not her most professional field, her knowledge is often the same, and Qin Yun's personal knowledge is very wide, including physics, chemistry, and machinery.

Her broad knowledge and broad view of the big picture are the fundamental reasons why she has been able to bring out many students who have made great achievements in various fields.

Whether there is a real guy in what Shen Chong wrote, she can know at a glance.

After a long time, she put down the piece of paper and was speechless for a long time.

The logic is rigorous, the formula is correct, and the inferences are reasonable, this is only her most preliminary judgment.

But what's even more terrifying is that Shen Chong told her students all about the next direction of research and development.

Even for each stage of the study a complete inference, each time, he guessed the lower limit of each stage of the study.

"Auntie, although science needs practice to prove, perhaps there is a lower and upper limit for every research progress. If your student's research can push every step to the limit, even in the middle of the process, it may be able to barely reach a lifespan of three to five years. But I can only regret to tell you that my judgment is that every time the research progresses at the lower limit, it does not exceed two years in the end! ”

Shen Chong picked up the paper and explained line by line.

His conclusions are certainly well-founded and seamless.

It seems to be an inference, but in fact, it is simply a retelling of the demise of the unlucky company in the previous life.

It was based on facts, and he almost didn't bring out other people's experimental data.

It's not that he doesn't want to, it's that he doesn't know, that thing is secret after all, so he can only disguise what has happened as an inference.

But Qin Yun knows how to do it, and he can get a glimpse of the leopard.

Theory is the premise of practice.

Practice is the support of theory.

"You've done this before? Where is your lab located? ”

What Shen Chong wrote was too real, Qin Yun changed his previous judgment, thinking that he was not empty and white-toothed, but he didn't expect that he would still have the energy to dabble in other aspects in such a busy state, and his research would be so in-depth.

Shen Chong spread his hands, "There is no laboratory, I haven't studied this too deeply, I just read some papers." ”

"You can get to this point just by reading papers?"

Qin Yun's eyes widened, and he felt that he was talking nonsense.

It's not that she hasn't seen the world, she has seen more of the world, and the research level shown by Shen Chong is not particularly exaggerated, as far as the project team that her students are now leading can naturally reach it after steady progress.

But what she is afraid of is that the result is really as Shen Chong said, which means that a billion dollars of funds have been wasted at every turn, and only some patents that may or may not be useful can be left behind.

It's not just money that's lost, it's time, it's the market.

The competition in science and technology has always been like this, losing step by step, losing step by step.

Unless a genius can be born, he can drag this field to catch up with him with his own strength.

Is Shen Chong such a genius?

But even if he was, he couldn't have focused his energy on this, how did he think of so much?

Just brains?

So what do we spend so much money on to raise the R&D team?

Since he has already started to pretend to be forced, Brother Shen can only continue shamelessly, "Ahem, I really don't have a laboratory!" Auntie, please rest assured, we didn't go on a different line and didn't crash. I'm not going to steal business with you. ”

Qin Yun said angrily, "I've never been afraid of competition, not to mention that what I'm earning now will be your daughter's sooner or later!" ”

Shen Chong was slightly embarrassed, and he said the wrong thing again, he quickly changed the topic, "In fact, there is a way to solve the problem of diaphragm, you can use composite film, of course, the weaving process has to be changed again......

Anyway, it's all inferences, so let's just continue to push it deeper, so as to save the mother-in-law from holding on to the previous question.

Then he began to write again, moving out the polymer materials developed by another company in his previous life.

He doesn't know the specific process, but he knows the result, and he doesn't need to talk too much to Qin Yun, give a range of physical and chemical properties to the final product, and then just point out the manufacturing process of the composite film.

It's just like talking to someone who knows how to do it, you don't need to be meticulous, as long as Qin Yun is given the right direction, she can make people come up with finished products, it's nothing more than spending money and time.

After a long time, Qin Yun was shocked again after reading the second scratch paper, "This is also what you deduced with theory?" ”

Shen Chong nodded, "That's right." ”

The mother-in-law was speechless.

She had seen many geniuses and had heard of Shen Chong for a long time, but the truth was still completely beyond her comprehension.

Does this son-in-law have a laboratory in his head?

Brother Shen was a little embarrassed to see his mother-in-law being shocked and scorched on the outside and tender on the inside.

And even if she turned to develop a new polymer separator to barely extend the life of lithium iron phosphate batteries, the project was doomed.

At best, she will be able to achieve part of her goal, and this new diaphragm will indeed break the foreign monopoly, but that is about it.

Shen Chong decided to say something more, just slap his mother-in-law in the face, and then watch her waste money, and his conscience can't help it.

Besides, she's right, she's wasting Shin Shin's money!

So, I'll just slap a sweet date.

"Auntie, listen to me again, in fact, what I really want to deny is not the polymer separator process, what I deny is the research direction of lithium iron phosphate batteries!"

Qin Yun could no longer hide her shock, "What do you mean by this?" ”

"What I mean is that at least within ten years, lithium iron phosphate batteries will not be able to solve the demand for new energy vehicles, and they are destined to be eliminated by another product. The energy density of lithium iron phosphate batteries is too low, and the cost of power storage per unit volume is too high. ”

Qin Yun reacted very quickly, "Is the other product you are talking about a ternary lithium battery?" It's impossible, that thing has completely failed in the market bidding and is on the verge of elimination, and the security is too low! ”

Brother Shen is very helpless, how can I do it, I will give you benefits, and I have to slap you in the face by the way?

Shen Chongzhen didn't deliberately want to embarrass Qin Yun.

He didn't dare to look down on his mother-in-law, he was really powerful, and the information he wrote was very brief, but Qin Yun swept it all over and grasped the main points.

At present, Qin Yun is a little behind in this field, and it is only behind the achievements of tens of billions of funds smashed by large enterprises in Shen Chong's previous life.

It's not that he is old Shen Niucha, he just copied the achievements of others.

He sighed, "Okay, Auntie, I'll tell you about how ternary lithium batteries can break through the safety drawbacks." ”

"Okay, I'll hear you."

He never dreamed that he didn't write a song and copy a public song, and he went around in a big circle, and finally caught a point where the world was not as good as his previous life, and became a science and technology copyist.
