Currently, the ternary lithium battery developed by China has several major disadvantages, the most important thing is safety.

Due to its poor stability, once the internal short circuit or the positive electrode encounters water, open flames are likely to occur, which will cause detonation.

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

The advantages of ternary lithium batteries are also obvious. After technological improvement, adjustment of formula and perfection of structure, the nominal voltage can reach 3.7v, with a larger energy density, and the same weight and volume battery pack, ternary lithium batteries can store more electricity.

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 need to consider a lot when buying things, and battery life is particularly important.

This is very realistic. What consumers care most about is how long it takes for me to recharge this car on a single charge and how far it can travel.

Shen Chong vomited all the information he learned when he helped him get a patent for others in his previous life.

"First, strengthen external protection, as long as you can withstand extreme car accidents. If you go through extremes, people will kneel on the spot, and it doesn't matter whether the car is burned or not. The so-called safety is relative, and fuel vehicles will also spontaneously ignite, and of course the same is true for electric vehicles. Then, through the battery management system, the overcharge protection, over-discharge protection, over-temperature protection and over-current protection are achieved to the extreme, which can greatly improve the safety of the ternary lithium battery pack and meet the standards that can be used in batches!"

He concluded so.

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

She believes that perhaps lithium iron phosphate batteries can narrow other gaps under the premise that their safety is better than ternary lithium and thus win the final victory.

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

Shen Chong smiled, "Auntie, you are like a mountain. The essence of a battery management system is a software system, and I can tell you the truth. The evolution of the software system is as fast as you imagine. Let me give you another example. Another defect of ternary lithium batteries is the charging and discharging life, right?"

Qin Yun nodded, "Yes, the performance will decay to only 55% after nine hundred charge and discharge cycles. 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 will be controlled at 25% to 75% each time. After three thousand charging and discharging cycles, the battery capacity can still be maintained at around 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 there and accidentally said too much. Who would have thought that the data was not confidential in the previous life, and it has not come out yet!

He took out the paper and pen and said, "I calculated this myself, otherwise I will calculate it for you to do it for my aunt. It's a bit long and it will take about seven or eight hours."

Qin Yun waved her hand when she heard this, "Forget it, let's just pretend that you said the data is accurate."

Shen Chong immediately changed his words, "When it comes to cycle life, lithium iron phosphate batteries have a disadvantage under low temperature conditions, right? For example, in the winter in the northeast, it only takes 100 charge and discharge cycles, and this thing is scrapped! So, before the technology is completely reformed, lithium iron phosphate batteries will definitely fail! This is consistent with the disadvantages of the previous PP diaphragm. You can't sell them in the north, right? Or there are extreme weather in the south, what should I do?"

Qin Yun opened her mouth wide, and Shen Chong found out that it was indeed a dead knot. The research team just verified the matter last month.

He actually made this come out purely by his brain!

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

He is ten times more genius than the rumored one!

No, a hundred times!

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

She struggled dyingly, "but the problem of performance decay at low temperatures can be overcome slowly through research."

Shen Chong, who had already known the conclusion, shook his finger, "No, it cannot be overcome, at least it cannot be solved within ten years. Lithium iron phosphate batteries can only be used on buses with larger spaces, buses, and are only fixedly placed in warmer climates, and replaced by fuel vehicles in extreme temperatures. In the field of private cars with a wider market, it will definitely fail!"

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

Shen Chong, the technology copyist, perfectly interprets a truth that even the most decent people may lose their self-control when they take advantage of the foresight and pretentiousness, and then be complacent and do not know how to advance or retreat.

Qin Yun was completely silent and could not say a word after watching this proud guy for a long time.

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

If someone outside knows it, he may be shocked to fall.

Qin Yun has debated with others countless times in her life, with more victory and less loss.

But losing so quickly is the first time in history.

It was the first time I lost so thoroughly.

It was the first time I lost to a junior who was over 20 years younger than her!

Seeing that his mother-in-law stopped talking, she looked at him with a strange and unpredictable look. Brother Shen shook his finger and had no time to close his right hand in the air.

It's finished, it's finished!

I'm over-pretending 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? Don't you want to build a great country for your daughter?"

Qin Yun didn't say anything thoroughly. Based on her past understanding of Shen Chong, this son-in-law is a talented person who can lead the era in any industry!

Yes, if Qin Yun’s other students are geniuses, she herself is also a genius.

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

Shen Chong really wants to cover his face, he is worthy of being Lao Lin’s biological mother!

He always pulls people, and you two mothers are really printed on the same mold!

"Ahem, auntie, it's time to eat. Otherwise, you'll be hungry and Xinxin's mother won't spare me."

He quickly ran away, turned around and ran away.

The child's mother asked that he could enter the left ear and exit the right ear without any burden.

But today I'm afraid I offended my mother-in-law a little deeper, Shen Tai Chi will leave you!

Next, Shen Chong saw what the thrilling and decisive movements were like Lao Jiang. Qin Yun was picking up food on the dining table with elegant movements but windy wind, while on the other hand, she called her student, the chief engineer who controlled the company on the spot.

"Stop researching lithium iron phosphate batteries, keep all the information, and start from now on, and I will give you the specific research plan in three days."

With such a major decision, there was no intention of resisting and questioning on the other side of the phone.

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

"No, before coming up with results, ask all project personnel to sign a new confidentiality agreement."

"OK!"

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

The little nanny Tang, who was waiting beside him, quickly got up and went straight to the kitchen. She knew Teacher Qin's habits.

He was checking Xinxin's homework on the other table, but secretly looked at Shen Chong here and was smacking his tongue.

I really didn't see that my mother-in-law, who is not fat, is very fed and is almost half as good as hers!

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

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

Today I beat my mother-in-law in the face so badly that she had no project. I had to do something to save her relationship.

He had already prepared all kinds of ingredients in the kitchen, so he just fryed it and acted quickly. After more than ten minutes, he served three more dishes.

"Auntie, please."

Qin Yun tried to grab two bites, "It's good, it's better than Xiao Tang's skills. If you want to participate in the competition, you can win the prize."

Chen Kuangren quickly became modest, "Auntie has been too proud, so he dare not take it."

Xinxin came over from the side and slandered the scene, "Grandma is right! Dad can get the first place! Because Dad is a human being, Dad is the best!"

In Xinxin's heart, a father is the best in everything!

Brother Chen covered his face.

Sure enough, Qin Yun asked Xinxin with a smile, "Who is better, dad or grandma?"

This made Xinxin stumped.

She thought for a long time and asked tentatively: "Dad is running fast? Grandma is old?"

Xinxin thought, Dad must have something better than grandma, but grandma also has something better than dad.

Shen Chong decided to turn around and instill an important concept in Xinxin. Age is not an advantage for women. Even if this is Xinxin, your grandmother, you can’t just say it casually!

"Xinxin has become a little slippery."

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

Mr. Chen hesitated a little. In fact, the real core of Shichu Technology is in the transformed ranch, but he responded, "Yes."

"I heard that your company's enterprise server system was written by you? Do you have any research on artificial intelligence and big data?"

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

Qin Yun was speechless.

Aren’t you crazy just now? When you talk about what you are best at, you will know a little bit?

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

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

Shen Chong: "Ha?"

This is OK?
