Monster Catching Daddy

Chapter 440 Pretend to Harvest Twice (Second Change)

At present, the ternary lithium battery developed by Huaguo has several major drawbacks, the first of which is safety.

Due to its poor stability, once the internal short circuit or the positive electrode encounters water, it is easy to generate an open flame and cause an explosion.

But these problems can be improved by strengthening the external protection and improving the safety performance of the battery itself.

The advantages of ternary lithium batteries are also obvious. After technical improvement, adjustment of formula and perfect structure, its nominal voltage can reach 3.7V, and its energy density is higher. In the case of battery packs with the same weight and volume, ternary lithium batteries can Reserve more power.

In short, compared with lithium iron phosphate batteries, new energy vehicles using ternary lithium batteries can run faster and farther.

This is a huge advantage that lithium iron phosphate batteries cannot match in the short term. Consumers have to consider a lot when buying things, and battery life is especially important.

This is very realistic. What consumers care most about is how long it will take to charge the car once I bought it, and how far it can run.

Shen Chong vomited out all the information he had learned in his previous life when he helped others to obtain patents.

"The first is to strengthen external protection, as long as it can withstand extreme car accidents. If it exceeds the extreme, people will kneel on the spot, and it doesn't matter whether the car burns or not. The so-called safety is relative, and fuel vehicles will spontaneously ignite Well, electric vehicles are of course the same. Then, through the battery management system to achieve the ultimate in overcharge protection, over-discharge protection, over-temperature protection and over-current protection, the performance of the ternary lithium battery pack can be greatly improved. It is safe and meets the standard that can be used in batches!"

He sums it up like this.

Qin Yun frowned. Of course she knew the direction, but she felt that it might not be so easy to implement.

She believes that perhaps through continuous technological progress, the lithium iron phosphate battery can close the other gaps and win the final victory on the premise that its safety is better than that of ternary lithium.

"Who knows how many years it will take to develop what you said? You also said that it is a huge system evolution process."

Shen Chong smiled, "Auntie, you are so far apart. The essence of the battery management system is a software system. I know this well. The evolution speed of software systems is faster than you can imagine. Let me give another example, three Lithium-ion batteries also have a shortcoming, charge and discharge life, right?"

Qin Yun nodded, "Yes, the performance will decay to only 55% after [-] charge-discharge cycles. Lithium iron phosphate batteries have a great advantage in this regard."

Shen Chong shook his head, "No, as long as the management system is improved and the charging and discharging process is controlled at 25%~75% every time, after three thousand charging and discharging cycles, the battery capacity can still be maintained at about 70%! In addition, the battery regeneration Technology will evolve too."

Qin Yun finally realized something was wrong, "Where did you get the data?"

Brother Shen is a little confused, let me go, I accidentally said too much, who would have thought that in the previous life, the data would not be kept secret at all, and it has not come out here yet!

He bit the bullet and took out a pen and paper, and said, "I figured this out myself, or I'll do the math for you, auntie? It's a bit long, and it will take about seven or eight hours."

Qin Yun waved her hands when she heard the words, "Forget it, let's just pretend that the data is accurate."

Shen Chong immediately changed his words, "When it comes to cycle life, lithium iron phosphate batteries still have a disadvantage at low temperature, right? For example, in winter in Northeast China, it only needs [-] charge-discharge cycles when it is below minus ten degrees Celsius. Things are scrapped! Therefore, before the technology is completely innovated, lithium iron phosphate batteries will undoubtedly fail! This is consistent with the disadvantages of the previous PP separator, so we have to sell it to the north? Or there is also extreme weather in the south, what should we do?"

Qin Yun's mouth opened wide. What Shen Chong found was indeed a deadlock. The research team just verified this matter last month.

He even came up with this purely with his brain!
What kind of son-in-law did my daughter find for me?
He is ten times more talented than rumored!
No, a hundred times!
Qin Yun really didn't expect that a simple academic discussion tonight would make herself speechless.

She was dying, "but the problem of performance degradation at low temperatures can be overcome slowly through research."

Shen Chong, who already knew the conclusion, shook his finger, "No, it can't be overcome, at least within ten years. Lithium iron phosphate batteries can only be used on buses and buses with larger spaces, and they are only used in warm climate areas. In extreme temperatures, it is replaced by a gasoline car. In the field of private cars with a wider market, it is bound to fail!"

God knows that this is the first time he has sentenced Qin Yun to death in a short period of time.

Tech copy master Shen Chong perfectly explained the truth, no matter how decent a person is, when they take advantage of the foresight to pretend to be aggressive, they may lose their self-control ability, and then get carried away with complacency and don't know how to advance or retreat.

Qin Yun was completely silent, looking at this frightened guy for a long time before he could say a word.

Qin Yun was indeed persuaded by him, and lost in this academic debate between mother-in-law and son-in-law.

If an outsider knew about it, his jaw would drop in shock.

Qin Yun has debated countless times with others in his life, winning more than losing.

But it was the first time in history that he lost so quickly.

It was the first time that he lost so thoroughly.

It was the first time to lose to a junior who was more than 20 years younger than her!
Seeing that the mother-in-law stopped talking and looked at herself with a strange and unpredictable look, Brother Shen's right hand, which he had not had time to retract after shaking his fingers, was fixed in mid-air.

It's over, it's over, it's over!

I'm overplaying it again!

"Auntie, listen to me..."

Qin Yun interrupted him, "Shen Chong, are you interested in changing your career? Otherwise, you will come to Shenglin Group? You don't want to make a good country for your daughter?"

Qin Yun didn't say something clearly. According to her previous understanding of Shen Chong, this son-in-law is a genius who can lead the times in any industry!
Yes, if Qin Yun's other students are geniuses, she herself is also a genius.

Then Shen Chong can only be called a genius!
Shen Chong really wanted to cover his face, as expected of Lao Lin's own mother!
Pulling people at every turn, you two mothers are really printed out of the same mold!
"Ahem, auntie, it's time to eat. Otherwise, you'll starve to death, and Xinxin's mother won't let me go."

He quickly slipped away, turned around and ran.

According to the child's mother's request, he can go in the left ear and out the right ear without any burden.

But today I’m afraid I’ve offended my mother-in-law a little too deeply, Shen’s Tai Chi will leave you!

Next, Shen Chong saw what it means to act vigorously like an old ginger. Qin Yun, on one side of the dinner table, moved gracefully but swept away vegetables, and on the other hand, she gave them to her student on the spot, the president who holds a controlling stake in the company. The engineer is on the phone.

"Stop the research and development of lithium iron phosphate batteries, keep all the information, and focus on ternary lithium batteries from now on. I will send you the specific research plan in three days."

With such an important decision, the other side of the phone didn't even have the slightest intention of resisting doubts.

"Good teacher, does this matter need to be announced publicly?"

"No, all project personnel are required to sign a new non-disclosure agreement before delivering results."

"Row!"

After hanging up the phone, Qin Yun tried to pick up some food again, but suddenly stopped and found that there was not much food left on the table.

Nanny Xiao Tang who was waiting by the side quickly got up and went straight to the kitchen. She knew Teacher Qin's habits.

Shen Chong, who was checking Xinxin's homework on the other side of the table, secretly looked at him and clicked his tongue.

I really didn't see it, the mother-in-law, who is not fat, has a big appetite, almost catching up with half of my own!

Qin Yun turned her head and looked at Shen Chong, "Shen Chong, go to the kitchen and cook me two dishes, I will try your skills."

Chef Shen immediately got up and went straight to the kitchen, "Okay!"

I beat my mother-in-law so badly today, she lost all the projects, and I have to do something to restore the relationship.

All kinds of ingredients had already been prepared in the kitchen, so he just fried them very quickly, and served three more dishes in ten minutes.

"Auntie, please."

Qin Yun tried to squeeze two bites, "It's not bad, it's better than Xiao Tang's craftsmanship, you can win prizes if you go to participate in the competition."

Shen Kuangren hastened to be humble, "Auntie has been praised too much, I dare not be her."

Xinxin came over from the side to disrupt the stage on the spot, "Grandma is right! Daddy can get No.1! Because Daddy is Superman, Daddy is the best!"

In Xinxin's heart, Superman's father is the most powerful in everything!

Brother Shen covered his face.

Sure enough, Qin Yun asked Xinxin with a smile, "Then who is better, father or grandma?"

Now Xinxin was stumped.

She thought for a long time, and asked tentatively, "Dad runs fast? Grandma is older?"

Xinxin thought, Dad must be better than grandma, but grandma is also better than dad.

Shen Chong decided to instill an important concept in Xinxin when he turned around. Old age is not an advantage for a woman. Even if this is Xinxin's grandmother, you can't just say it casually!

"Xinxin has become a little cunning."

Qin Yun was not angry, but touched the back of Xinxin's head, and said casually, "Shen Chong, does your current company only make some kind of tuning software?"

Mr. Shen hesitated a little. In fact, the real core of Stone Hammer Technology is in the pasture that is being transformed, but he responded, "Yes."

"I heard that you wrote your company's enterprise server system yourself? Do you have research on artificial intelligence and big data?"

This is Shen Chong's professional field again. He nodded and said modestly, "Fortunately, I know a thing or two."

Qin Yun was speechless.

Weren't you crazy just now, when you talk about what you are best at, you know a thing or two?

Seeing that the mother-in-law's expression was wrong, Shen Chong quickly changed his words, "Well, this is my specialty."

"Well, according to the improvement direction you just proposed, the ternary lithium battery should be successfully developed within half a year. On behalf of Shenglin Group, I will outsource all the business of the battery management system to you. Your Stone Hammer Technology will become Shenglin Group. How about your core supplier?"

Shen Chong: "Huh?"

Does this work too?
I accidentally took another big business?

But I plan to sell the whole company and cash out at a high position!
Seeing him in a daze, Qin Yun said again: "No, you are planning to sell Stone Hammer Technology, right?"

"Ah? Auntie, how do you know? Xinxin's mother said it?"

"No, I guessed."

Brother Shen is simply horrifying. Your vision is too vicious. I investigated my four major controlling parties who invest in me and didn't even guess it. You actually figured it out just by guessing!

How obvious am I?
If it is discovered, will the price be lowered?

He began to worry about gains and losses again.

Qin Yun asked him again, "Or set up a joint venture company, what do you think?"

"Auntie, let's talk about it at that time, but I will definitely be able to pick it up, but how to operate it will be decided at that time."

"It's enough to have your words. Don't worry, although I use your daughter's money, I will not treat you badly."

Mother-in-law's words always sounded wrong, but Shen Chong didn't bother to think about it carefully.

Qin Yun continued to eat this meal, and she suddenly asked a new question, "Shen Chong, I have considered using the radioactivity of metal isotopes to develop a slow-release nuclear power source. Do you think this direction is a bit out of the blue?"

She really regarded Shen Chong as a super genius, and even asked such wild ways.

Brother Shen shook his head on the spot, "It's unrealistic, at least I have no idea now."

While he was talking, a thunderbolt exploded in his head.

Metal isotopes?
Isotopes of Iron!
radioactivity?
The iron thief who haunted Panhua City!

Got it!
