When the temperature of the electric vehicle battery is low, the battery life will be fractured, or even more, and the main reason for this is that the internal resistance of the battery increases, and the viscosity of the electrolyte increases, resulting in a decrease in conductivity.

At present, the main methods to solve this problem are mainly to alleviate the low-temperature performance attenuation of lithium-ion batteries through physical heating, which is useful and must be available, but it is still not perfect

Or choose a battery type with better low temperature resistance, for example, ternary lithium-ion batteries have better charging and discharging performance at low temperatures than lithium iron phosphate batteries, but this battery is less safe than lithium iron phosphate.

Now, the LZ-1 compound that Dr. Li stumbled upon can solve this problem perfectly.

The company's laboratory is further testing the future commercial viability of this compound in lithium batteries.

For example, more extreme performance under various temperature, voltage and current conditions, including capacity, cycle life, safety, etc.;

Also see if it will produce adverse chemical reactions or affect the battery structure after a long time.

If the specific commercial use is concerned, it must also depend on the cost of synthesis, if the cost is too high, commercialization is impractical.

Finally, whether it meets the requirements of environmental protection, Wu Zhou does not want what his company invents to eventually cause harm to human health and the natural environment.

When the data in the laboratory was not completely out, Wu Zhou had already pushed the final result from the system.

There is no need to go into detail in terms of performance, the data is clearly there.

It is only necessary to add about 1% of the content of LZ-1 to the battery liquid, which can bring about 20% or more of the battery reserve at room temperature, and when the climate is cold, it is 100% improved.

In terms of long-term use, it is also very safe, and it can even be said that the safety of the current battery has been improved.

After Wu Zhou read all the data, he couldn't suppress a smile on his face, and then took out his mobile phone.

On the other side, in the BYD workshop, Mr. Wang wore the same work clothes in the workshop and inspected the operation of each production line.

He has a very strong sense of pride in his company, many years of hard work, BYD is a collection of automobiles, batteries, electronics, new energy and other diversified industries in one of the high-tech enterprises, with a complete industrial chain from batteries, motors to electronic control independent research and development and production capacity, which is a lot of competitors can not match the integration of the whole industry chain advantage.

At this moment, his Huawei phone rang, and he glanced at the phone screen, only to find that it was an unfamiliar number.

After hesitating for a moment, he still answered the phone, because there are not many people with his private number, and as for those advertising sales, real estate agents and the like can't call at all.

"Hello, Mr. Wang, I am Wu Zhou of Aiying Group." Mr. Wang listened to a gentle and polite voice on the other end of the phone, and was slightly stunned.

Subconsciously I wonder if I've met a liar.

Although Wu Zhou has not been in contact with him, as the largest snack brand in China, the largest mask brand, and the name of the first good in China, he must know it. Although Mr. Wang has never seen Wu Zhou in person, he still has some admiration for Wu Zhou from the bottom of his heart.

At the beginning, their company also wanted to help the country produce emergency masks, but later found that it seemed to be a little redundant. Because Aiying Group has produced abundant masks, and in the process of this matter, Aiying's series of actions have also been tracked by the official media in an all-round way, and in 2019, a total of tens of billions of companies were sold, and tens of billions of dollars were donated

This is a true patriotic entrepreneur who spares no expense, and he admires people like Wu Zhou.

"Hello, Mr. Wu, I'm Wang Chuanfu." Mr. Wang replied, a little vigilant in his heart, and the assistant next to him glanced at the number displayed on Mr. Wang's mobile phone for the first time, and then immediately contacted the relevant personnel to inquire about the ownership of the number.

However, Mr. Wang on the other end of the phone was the person on the other end of the phone by default, who was Wu Zhou, and continued, "I don't know what happened to Mr. Wu's call this time?" I didn't ask Wu Zhou where he knew his phone number.

Wu Zhou got straight to the point, "I want to talk to you about a cooperation project on lithium-ion batteries. ”

"Lithium-ion batteries?" Mr. Wang was surprised, and even a weird smile appeared on his face, thinking in his heart that the person opposite was most likely a liar, and looked at the assistant beside him. The assistant is still checking according to the number on his mobile phone at the moment, and he hasn't found it yet.

"Isn't Aiying Group mainly engaged in food and masks? What does it have to do with lithium-ion batteries? Mr. Wang asked with a smile and expressed his confusion.

Wu Zhou also heard the doubts in Mr. Wang's heart from Mr. Wang's tone, but he didn't care and continued, "Our company has a lot of projects, and this point can't be said clearly on the phone for a while. I won't say much about this, let's get straight to the point, our company has a new material research and development department, and a new compound has been discovered, which we call LZ-1, and adding it to the electrolyte salt can greatly improve the performance of lithium-ion batteries," Wu Zhou roughly said some data parameters.

At the beginning, Mr. Wang on the other end of the phone also glanced at the assistant next to him, and the assistant's face was red at the moment, his forehead was sweating, and he still shook his head.

But then after hearing the series of data that Wu Zhou said, Mr. Wang no longer looked at his assistant at the moment, but communicated with Wu Zhou on the phone to get more detailed data.

After going back and forth, he heard a lot of details, and even very professional details, Wu Zhou could answer them one by one and give detailed reasons.

The level of professionalism is as if he is communicating with a senior R&D person within the group.

"Mr. Wu, it's convenient for me to go to your company, I'm very interested in this compound."

"Of course, I welcome Mr. Wang."

Although there were still doubts in his heart, Wang always felt that Wu Zhou might be 'wrong'.

About half an hour after he hung up the phone with Wu Zhou, the assistant gave him a preliminary investigation report, and after reading it, Mr. Wang realized that his understanding of Wu Zhou was too one-sided.

"So many cross-borders?"

I used to think that Wu Zhou sold a lot in snack companies, and the plate was very large, but I didn't expect it to be so big, and there are a lot of cross-border industries, food, masks, biomedicine, and mechanical design and processing, etc.

BYD can cross the border because of decades of accumulation and accumulation, but Aiying Group has only been a few years, and the point is that it seems to have done well, even if it has just entered the medical field, there are already products presented, and it is also the world's leading achievement, not only the leading in China.

"So many patents? Most of them are invention patents? ”

The patent applied for by Aiying Group is even more outrageous.

Authorized + applied for patents, a total of 3387, of which 2322 are invention patents, 698 practical patents, 367 appearance patents, and most of them are applied for this year, and after a closer look, you can see that many of these patents seem to be patents with actual commercial value, but because the application details are not disclosed, so you can't see the specific role of these patents, but looking at the general introduction of these patents, you can also understand that they are some technologies that can be really landed.

Of course, the most important thing is that the vast majority of them are invention patents and utility model patents, not appearance patents with little technical content.

Invention patents refer to new technical solutions proposed for products, processes or their improvements;

A utility model patent refers to a new technical solution for the shape, structure or combination of a product that is suitable for practical use;

A design patent refers to a new design of a product that is aesthetically pleasing and suitable for industrial application based on the shape, pattern or combination thereof, as well as the combination of color and shape and pattern.

The term of patent protection for invention patents is 20 years, while for utility patents and appearance patents is 10 years. From this, it can also be seen which patent is more technical.

On the last page of the information, he finally saw the invention patent application for the LZ-1 new material that he had just communicated with Wu Zhou.

"Arrange for me to get the earliest plane to Cloud City, immediately, quickly."
