When the temperature of electric vehicle batteries is low, the battery life will be broken or even more. 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 to alleviate the low-temperature performance degradation of lithium-ion batteries through physical heating. It is definitely useful, but it is still not perfect.
Or choose a battery type with better low-temperature resistance. For example, ternary lithium-ion batteries have better charge and discharge performance at low temperatures than lithium iron phosphate batteries, but this battery is less safe than lithium iron phosphate.
But now the LZ-1 compound that Dr. Li accidentally discovered can perfectly solve this problem.
The company's laboratory is still further testing the future commercial feasibility of this compound in lithium batteries.
For example, performance under more and more extreme temperature, voltage and current conditions, including capacity, cycle life, safety, etc.;
Also check whether it will produce adverse chemical reactions or affect the battery structure after a long time.
For specific commercial use, it will definitely depend on the synthesis cost. If the cost is too high, commercialization will be unrealistic.
Finally, whether it meets environmental protection requirements, Wu Zhou does not want the things invented by his company to end up harming human health and the natural environment.
Before the data in the laboratory was fully released, Wu Zhou had already pushed the final results from the system.
There is no need to go into details about performance, the data is clearly there.
It seems that only about 1% of LZ-1 needs to be added to the battery liquid to bring about more than 20% of the battery reserve capacity at room temperature. As for the cold climate, it is a 100% increase.
In terms of long-term use, it is also very safe, and it can even be said to have improved the safety of current batteries.
After Wu Zhou read all the data, he couldn't hold back the smile on his face, and then took out his mobile phone.
On the other side, in the BYD workshop, Mr. Wang was wearing the uniform work clothes found in the workshop, inspecting the operation of each production line.
He has a very strong sense of pride in his company. After years of hard work, BYD is a high-tech enterprise integrating automobiles, batteries, electronics, new energy and other diversified industries. It has a complete industry from batteries, motors to electronic controls. The chain's independent R&D and production capabilities are advantages of whole-industry chain integration that many competitors cannot match.
At this moment, his Huawei phone rang. He glanced at the phone screen and found it was an unfamiliar number.
After hesitating for a moment, he still answered the phone because there weren't many people with his private number, and as for those advertisements and promotions, real estate agents and the like couldn't get in at all.
"Hello, Mr. Wang, I am Wu Zhou from Aiying Group." Mr. Wang was slightly startled when he heard a gentle and polite voice coming from the other end of the phone.
Subconsciously I thought I had met a liar.
Although he has not come into contact with Wu Zhou, as China's largest snack brand, largest mask brand, and China's first good reputation, he must be aware of it. Although Mr. Wang has never met Wu Zhou in person, he still admires Wu Zhou from the bottom of his heart.
At first, their company also wanted to help the country produce emergency masks, but later found that it seemed a bit redundant. Because the Aiying Group produced sufficient masks, and during this incident, Aiying's series of actions were also tracked by the official media. In 2019, a company that sold tens of billions of masks in total actually donated more than 100,000 masks. Ten billion
This is a truly patriotic entrepreneur who spares no expense. He admires people like Wu Zhou very much.
"Hello, Mr. Wu, I am Wang Chuanfu." Mr. Wang replied, feeling a little wary. The assistant next to him immediately glanced at the number displayed on Mr. Wang's mobile phone, and then immediately contacted the relevant personnel. , I want to check the owner of this number.
However, Mr. Wang on the other end of the phone assumed that the person on the other end of the phone was Wu Zhou, and continued, "I wonder what Mr. Wu is calling this time?" He did not ask Wu Zhou where he got 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 battery?" Mr. Wang was surprised, with a weird smile even appearing on his face. He thought to himself that the person opposite was probably a liar, and looked at the assistant beside him. The assistant is still searching based on the number on his mobile phone, but he hasn't found it yet.
"Isn't Aiying Group mainly engaged in food and mask business? What does it have to do with lithium-ion batteries?" Mr. Wang asked with a smile, expressing his confusion.
Wu Zhou could also hear the doubts in Mr. Wang's heart from Mr. Wang's tone, but he continued without paying attention, "Our company has many projects. I couldn't explain this clearly on the phone at the moment. Mr. Wang can ask his assistant to check it out later." The business scope of our company. I won’t say much about this, and will go directly to the topic. Our company has a new material research and development department. We have discovered a new compound, we call it LZ-1, and add it to the electrolyte salt. In the end, the performance of lithium-ion batteries can be greatly improved." Wu Zhou briefly talked about some data parameters.
When Mr. Wang on the other end of the phone just started, he glanced at the assistant beside him. The assistant's face was red now, sweat was pouring from his forehead, but he still shook his head.
But after hearing the series of data Wu Zhou said, Mr. Wang no longer looked at his assistant at this moment, but communicated with Wu Zhou on the phone for more detailed data.
After going back and forth, he heard a lot of details, even very professional details, and Wu Zhou was able to answer them one by one and give detailed reasons.
That level of professionalism was as if he was communicating with a senior R&D personnel within the group.
"Mr. Wu, could you please come to your company? I'm very interested in this compound."
"Of course, I welcome Mr. Wang."
Although he still had doubts in his heart, Mr. Wang felt that Wu Zhou might be 'wrong'.
The assistant gave him a preliminary investigation report about half an hour after he hung up the phone with Wu Zhou. After reading it, Mr. Wang realized that his understanding of Wu Zhou was too one-sided.
"Crossing so many fields?"
I used to think that Wu Zhou sold a lot in the snack company and the plates were very big, but I never expected that it would be that big, and there are quite a lot of cross-border industries, including food, masks, biomedicine, and mechanical design and processing. Etc., etc.
BYD's ability to cross-border is the result of decades of accumulation, but Aiying Group is only a few years old, and the point is, it seems to be doing well. Even in the medical field, which has just entered the industry, it has products. It’s a world-leading achievement, not just a domestic one in China.
"So many patents? Most of them are invention patents?"
The patent applied for by Aiying Group is even more outrageous.
There are a total of 3,387 patents authorized and applied for, of which 2,322 are invention patents, 698 utility patents, and 367 appearance patents. Most of them were applied for this year, and after a closer look, you can see that among them Many patents seem to have actual commercial value. However, because the application details are not disclosed, the specific functions of these patents cannot be seen. However, looking at the general introduction of these patents, it can be understood that they are all practical applications. Technology that is actually coming to fruition.
Of course, the most important thing is that most of them are invention patents and utility model patents, rather than appearance patents with little technical content.
Invention patents refer to new technical solutions proposed for products, methods or their improvements;
Utility model patents refer to new technical solutions proposed for the shape, structure or combination of products that are suitable for practical use;
A design patent refers to a new design that is aesthetically pleasing and suitable for industrial application, based on the shape, pattern, or combination of a product, as well as the combination of color, shape, and pattern.
The patent protection period for invention patents is 20 years, while utility patents and appearance patents have a 10-year term. From this we can also see which patent has more technical content.
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 the earliest flight to Yuncheng, immediately, quickly."
