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 produce an open flame, which will cause an explosion.

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

The advantages of ternary lithium battery are also obvious, after technical improvement, adjustment of formula and perfect structure, its nominal voltage can reach 3.7V, the energy density is larger, the same weight and volume of battery pack, ternary lithium battery 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 of lithium iron phosphate batteries that cannot be compared in the short term, and consumers have to consider a lot when buying things, and battery life is especially important.

This is very realistic, and what consumers care about most is how long it will take me to buy this car and how far it can run on a single charge.

Shen Chong spit out all the information he learned when he helped his partner to make patents for people in his previous life.

"The first is to strengthen external protection, as long as it can withstand a car accident in an extreme situation. If it is more than extreme, everyone will kneel on the spot, and it doesn't matter if the car burns or not. The so-called safety is relative, fuel vehicles will spontaneously combust, and electric vehicles are of course the same. Then, through the battery management system, the overcharge protection, over-discharge protection, over-temperature protection and over-current protection can be used to the extreme, which can greatly improve the safety of the ternary lithium battery pack and reach the standard that can be used in batches! ”

He summed it up this way.

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

She believes that perhaps after continuous technological progress, lithium iron phosphate batteries can narrow other gaps under the premise that their safety is better than that of ternary lithium, and then win the final victory.

"Who knows how many years you're talking about? As you said, it's a huge phylogenetic process. ”

Shen Chong smiled, "Auntie, you are like a mountain, the essence of the battery management system is a software system, and I know this." Software systems are evolving faster than you think. Let me give you another example, there is also a defect in ternary lithium batteries is the charge and discharge life, right? ”

Qin Yun nodded, "Yes, after nine hundred charge-discharge cycles, the performance will decay to only 55% left." Lithium iron phosphate batteries have great advantages in this regard. ”

Shen Chong shook his head, "No, as long as the management system is improved, the charging and discharging process is controlled at 25%~75% every time, and after 3,000 charging and discharging cycles, the battery capacity can still be maintained at about 70%!" In addition, battery regeneration technology will also be developed. ”

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

Brother Shen was a little confused, I went, and accidentally said too much, who would have thought that the public data in the previous life was completely unconfidential, and it hadn't come out yet!

He took out a pen and paper and said, "This is also my own calculation, otherwise I will calculate it for your aunt?" It's a bit long, about seven or eight hours. ”

Qin Yun waved his hand when he heard this, "Forget it, let's just say that the data is accurate." ”

Shen Chong immediately changed his words, "When it comes to cycle life, lithium iron phosphate batteries have a performance drawback at low temperatures, right?" For example, in the winter of the Northeast, it is below minus 10 degrees Celsius, and only 100 charging and discharging cycles are needed, and this thing will be scrapped! Therefore, before the technology is completely revolutionized, the lithium iron phosphate battery will definitely fail! This is consistent with the disadvantages of the previous PP diaphragm, and you can't help but sell the north, right? Or maybe there is also extreme weather in the south, what should I do? ”

Qin Yun's mouth was wide open, and what Shen Chong pulled out was indeed a dead knot, and the research team had just verified this matter last month.

He actually pushed this out of his brain!

What kind of son-in-law did my daughter find me?

He is ten times more genius than rumored!

No, a hundredfold!

Qin Yun really didn't expect that a simple academic discussion tonight would make her dignified bull speechless.

"But the problem of performance degradation at low temperatures can be slowly overcome through research." ”

Shen Chong, who already knew the conclusion, shook his fingers, "No, it can't be overcome, at least it can't be solved in ten years." Lithium iron phosphate batteries can only be used in buses and buses with larger spaces, and are only fixed in warm climate areas, and replaced by fuel vehicles in extreme temperatures. In the wider private car market, it is bound to fail! ”

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

Shen Chong, a science and technology copyist, perfectly interprets the truth, no matter how decent a person is, when he pretends to be forced with the advantage of foresight, he may lose his self-control, and then get carried away and do not know how to advance or retreat.

Qin Yun was completely silent, looking at this stunned guy for a long time and couldn't say a word.

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

If an outsider knows, I'm afraid my jaw drops.

In Qin Yun's life, he has debated with others countless times, winning more and losing less.

But for the first time ever, he lost so quickly.

It's the first time I've lost so completely.

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 instead looked at herself with a strange and unpredictable look, Brother Shen's right hand, which he hadn't had time to collect after shaking his fingers, was fixed in the air.

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

I'm overdoing it again!

"Auntie, listen to me......"

Qin Yun interrupted him, "Shen Chong, are you interested in changing careers?" Otherwise, you come to Shenglin Group? You don't want to lay a great foundation for your daughter? ”

Qin Yun didn't say something thoroughly, according to her past 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 geniuses.

Then Shen Chong can only be said to be a god!

Shen Chong wanted to cover his face very much, he was worthy of Lao Lin's biological mother!

Pull people at every turn, you two mothers are really printed in a mold!

"Ahem, Auntie eats, it's time to eat. Otherwise, you will be hungry, and Xinxin's mother will not spare me. ”

He hurriedly slipped away, turned around and ran.

At the request of the child's mother, he can go in and out of the left ear without any burden.

But today, I'm afraid I'll offend my mother-in-law a little deeply, Shen's Taiji will go to you!

Next, Shen Chong saw what it means to be as vigorous and resolute as an old ginger, Qin Yun was at the dinner table with elegant but wind-swept vegetables, and on the other hand, she called her student, the chief engineer who held the company in the company.

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

With such a major decision, the other side of the phone did not have the slightest intention of resisting questioning.

"Okay teacher, does this need to be publicly announced?"

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

"Okay!"

Hanging up the phone, Qin Yun tried to pick up the dishes again, but suddenly had a meal and found that there were not many dishes left on the table.

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

was checking Xinxin's homework on the table on the other side, but secretly looked at Shen Chongzhi here.

I really didn't see it, but the mother-in-law who didn't look fat ate a lot of food, and she was about to catch up with half of herself!

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

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

Today, I made my mother-in-law's face miserable, and I had to do something to save the relationship.

The kitchen had already prepared all kinds of ingredients, so he just stir-fried them, and after ten minutes, he served three dishes.

"Auntie, please."

Qin Yun tried to take two bites, "It's good, it's better than Xiao Tang's craftsmanship, you have to go to the competition to win the prize." ”

Shen Madman hurriedly humbled himself, "Auntie is too prestigious, I don't dare to be it." ”

Xinxin came over from the side and demolished the stage on the spot, "Grandma is right!" Dad can take first place! Because Dad is Superman, Dad is the most powerful! ”

In Shin Shin'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, "Who is more powerful, dad or grandma?" ”

This stumped Shin Shin.

She thought for a long time and asked tentatively, "Daddy is fast?" How old is grandma? ”

Xinxin thought about it, Dad must be better than Grandma, but Grandma is also better than Dad.

Shen Chong decided to turn around and must instill an important concept in Xinxin, a woman's age is not an advantage, even if this is Xinxin's grandmother, you can't just say it!

"Shin Shin has become a little slippery head."

Qin Yun was not angry, touched the back of Xinxin's head, and then said casually: "Shen Chong, is your current company only doing that tuning software?" ”

Mr. Shen hesitated slightly, in fact, the real core of Stone Hammer Technology was in the ranch that was being transformed and formed, but he responded, "Yes." ”

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

This is Shen Chong's professional field again, nodded, and forcibly said modestly, "It's okay, I know a little bit about it." ”

Qin Yun was speechless.

Aren't you crazy just now, when it comes to what you're best at, you know a thing or two?

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

"In this way, according to the improvement direction you just proposed, the ternary lithium battery should be successfully developed within half a year, and I will outsource all the battery management system business to you on behalf of Shenglin Group, and your stone hammer technology will become the core supplier of Shenglin Group, how about it?"

Shen Chong: "Huh? ”

Is that okay?

I accidentally got another big business?

But I'm going to sell the whole company and cash out at a high price!

Seeing him in a daze, Qin Yun said again: "No, you're planning to sell Stone Hammer Technology, right?" ”

"Huh? Auntie, how do you know? What did Xinxin's mother say? ”

"No, I guess."

Brother Shen is simply terrifying, your vision is too vicious, others invested in me to investigate my four major controlling parties and didn't guess it, you actually guessed it!

Am I so exposed?

If it is discovered, will it be a price reduction?

He began to suffer from 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 this later, but I will definitely be able to take it, but how to operate it will be decided when the time comes."

"Just have your words, don't worry, although I use your daughter's money, I won't treat you badly."

The 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 a new question came up to her coldly, "Shen Chong, I have considered using the radioactivity of metal isotopes to develop a slow-release nuclear power supply, do you think this direction will be a bit fantastical?" ”

She really regarded Shen Chong as a super genius, and even asked about this kind of wild way.

Brother Shen shook his head on the spot, "It's unrealistic, at least I don't have an idea now." ”

As he spoke, a thunderbolt exploded in his head.

Metal isotopes?

Isotopes of iron!

The iron thief who haunts Panhua City!

Pregnant!
