- After the wedding, Su's father and Su's mother couldn't leave home, so they stayed for two days before returning home. The other people were not idle either. After a while of excitement, they all left one after another. Su Yunyi and Li wanted to go to the Human Resources Department to complete the registration procedures. The temporary arrangement was that Su Yunyi studied with He Xiuwen, and Li wanted to work under Wang Mei in the Finance Department. The two of them were undergraduates and had no work experience, so they had to find someone to supervise them first.
"Brother, why did the Human Resources Department set the levels of me and Su Yunyi so low? Are we that bad? Why don't you tell me and ask Brother Zhang to help us adjust the situation." Li Zhuang was about to speak to Brother Liu when Li Xiang stomped on the ground. He came over to complain and planned to go through the back door.
"Haha, Koala, tell your conscience, except for some people in the property management office, who else is worse than you? There are so many experts in the new energy laboratory, and Su Yunyi can get this level is already good." Li Zhuang knocked on his sister. head, teach her a lesson. Li Xiang's nickname was given by him, and he thought it was very appropriate at the time. Su Yunyi also likes to bark, of course when no one is around, otherwise he will definitely suffer physical pain.
Watching his sister leave dejectedly, Li Zhuang saw Brother Liu laughing: "Xiao Zhuang, when did my daughter get this nickname? I think it is very vivid and matches her well. Wesson Technology is a bit intellectually intensive. Gao, I guess you will become rich soon."
Li Zhuang smiled bitterly and said: "Brother Liu, it's not like you don't know the difficulties in the country. I'm thinking about how to open a breakthrough. Do you have connections with several automobile companies in the province?"
"No, we mainly make mobile phone batteries and laptop batteries, mainly for export. Lao Qi has some connections, but his company has not done any research on power lithium batteries. This technology is very high. Xiuwen said that you are now preparing to launch power lithium batteries. This is quite difficult, do you really think you can succeed?"
"Haha, of course, since I plan to engage in research and development, I am confident in this. However, pure electric vehicles may not be so easy. I plan to start with mild hybrid and full hybrid, and finally achieve full electric. Forget it, let's not talk about this? What about you? How did it go?"
When Brother Liu heard Li Zhuang mention Liu Jing's trouble, he couldn't help but sigh: "Now that the chaos is like this, it's a relief to go out. Xiao Zhuang, thanks to your help this time, there are many people from your company studying abroad in Citi Country Ah. Be careful, there might be spies. Bah, bah, look at my crow mouth."
"It's okay. If trouble does come, there's no point in pretending. Just take it step by step. It will come sooner or later." Li Zhuang is very optimistic. Larger R&D institutions either have commercial spies or people from relevant departments mixed in. . The real world is a world where thieves and robbers are rampant, which fully reflects the bad nature of human beings.
After sending Brother Liu away, Li Zhuang was secretly glad that Liu Jing's troubles were finally settled. This was not easy. He didn't think too much, turned around and got into the hexagonal building, very busy.
The Weisen Technology Tour Group did not stay in Australia for too long. There were many projects in the laboratory and the work pressure was high. Li Zhuang was busy recharging his batteries, mainly about materials science and ultra-precision processing, while He Xiuwen and Ackerman were busy working on a joint research team. He gave He Xiuwen a bunch of information, mainly about lithium battery technology, nanoelectrode preparation, electrolyte formula, and technical information on separator paper.
He Xiuwen was overjoyed after just scanning it, especially after seeing the process and technical description of the diaphragm paper. Diaphragm paper may not look like much, but it is actually in great demand. Currently, the annual domestic demand exceeds 50 million square meters. If electric vehicles are promoted on a large scale, the demand will far exceed this demand several times; the requirements are also not low, directly affecting important parameters such as battery internal resistance, discharge capacity, and cycle life. There are only a few domestic factories producing them. Performance is far from great. The separator paper currently used in Liuge's factory is either Citi's domestic product or Japanese product. High-quality batteries use single-layer PE separators, while ordinary ones use pp/pe/pp three-layer composite separators.
At present, the debate between lithium manganate and lithium iron phosphate as cathode materials for power lithium batteries is very fierce. Both have their own advantages and disadvantages, but like most domestic scientific researchers, He Xiuwen prefers lithium iron phosphate. The current domestic level in this regard is still average. Nanoparticles can only reach about 50 nanometers, which is quite far behind foreign countries. Foreign countries are already studying the preparation of 20 to 30 nanometers. Lithium iron phosphate has many advantages as a power battery, the two most important of which are excellent safety and cheap raw materials. It basically does not explode. However, it has many shortcomings and has been one of the focuses of research in recent years. There has been some progress domestically in the past two years, but not too much. Citigroup and Japan and South Korea are currently divided into two factions. Lithium manganate is the mainstream, and lithium iron phosphate is not without its ability to fight back. In the long term, lithium iron phosphate should still be the main direction.
He Xiuwen studied electrochemistry when he was studying for his Ph.D., and the electrolyte itself was the focus of his research. He has a high level of expertise in this area and has a number of patents in hand. I only knew a lot about the separator paper, and I had no intention of producing it myself. This time I saw the information that Li Zhuang obtained from some source, and I was overjoyed for a while.
"maleAs a researcher in the chemical industry department, you have to help me allocate a batch. I can guarantee that in two months, we will realize the mass production process research of 10-12 micron single-layer PE film. The mass production will be controlled at around 13-14 microns, which will not be better than that of foreign products. Poor, at least to achieve the same level, the research on ultra-thin composite membranes with better performance will be completed," he told Li Zhuang.
Having a powerful tool in hand increases your confidence.
Li Zhuang asked He Xiuwen to discuss with Zhou Qisen. He didn't know much about this, and he could only have a slight understanding. A month later, He Xiuwen told him that there was a way to produce uniform particles of 20-nanometer lithium iron phosphate. The joint research team had solved problems such as conductivity, oxidation, electrode crystallization, agglomeration of heavy-discharge particles and improvement of tap density.
"20 nanometers, are you right?" Li Zhuang, who had learned about the nanotechnology of lithium iron phosphate during this period, was shocked. At present, domestic large-scale preparation has just passed the 50-nanometer threshold.
"I have estimated that if we can achieve mass production of uniform particles of 10 to 15 nanometers, add improved ultra-thin multi-layer composite separators and electrolyte materials, and nanonize the negative electrode materials, we can achieve close to the theoretical ratio in the laboratory. With products with high capacity and nano-supercapacitors, electric vehicles will be easy to use.¡±
He Xiuwen¡¯s words are astonishing.
Of course, Li Zhuang also understands that it is not easy to realize lithium iron phosphate particles below 20 nanometers. The problem of reducing lithium iron phosphate to single-phase iron has always been troublesome, and this is a taboo for batteries unless the level of separators is developed to a very high level. It is estimated that the single layer is somewhat difficult. This problem can only be reduced by using a three-layer composite separator with special materials in the middle. However, there are some problems with the thickness of the three-layer composite separator, and it is not simple to manufacture.
This is a dilemma. Lithium iron phosphate particles cannot be made infinitely small. 10 nanometers may have exceeded its limit. The purity problem is not so easy to solve.
Li Zhuang misses carbon nanotubes and pure graphene supercapacitors a bit. As long as batch preparation can be completed, these problems can be easily solved. Based on the current level of Wesson Technology, it is estimated that it will take at least ten years. This area is now all about playing with concepts, as Zhou Qisen said, "If graphene is fooled by the scientific community, countless research institutes will go bankrupt."
"I have found a solution to the problem of low-temperature capacity loss of lithium iron phosphate, which is to prepare the relevant experimental materials again. It is a special metal compound that can effectively increase the specific capacity and tap density of lithium iron phosphate to reach The existing theoretical level of lithium cobalt oxide is even slightly exceeded."
"Also, if lithium iron phosphate power battery blocks are prepared in batches, the uniformity requirements are very high. Can you borrow your baby from the factory? Or you can raise the factory's automation module to the laboratory level, which can be easily solved," He Xiuwen said. Ever since the loudspeaker made an amazing appearance last time, he has been obsessed with it. Li Zhuang has been annoyed by him several times, but he never let him succeed.
Regarding the promising nickel-cobalt-manganese material, He Xiuwen has not forgotten it. He plans to solve the common problems of this material and use it in the fields of communication batteries and small power. Lithium manganate He plans to do some research to see who will have the upper hand in the future. If the wind is not going in the right direction, he can follow up at any time. Purely theoretical research takes a long time, and basic theoretical research in the laboratory is still relatively weak.
Li Zhuang always thought that he was greedy, but he didn¡¯t expect that this guy was not bad at all, or even worse. Fortunately, the tools are good now, otherwise he wouldn¡¯t know how much investment he would have to make to see the results.
After the "Ackerman Bow Incident" occurred, Li Zhuang reset the authority of laboratory personnel to use loudspeakers. Large-scale experimental systems can only be used when the laboratory director is present, so as not to cause additional burden on the loudspeakers and lead to leaks.
Since the big speaker was relocated, there has been no expert system in charge of the Liuge factory. Now it is mainly controlled by the lf3 lithium battery manufacturing expert system, which is certainly not comparable to the big speaker. When He Xiuwen saw that scene, he always missed it very much. He always tried to persuade Li Zhuang to let the main computer of the Hexagon Building participate in the factory management. Of course, he didn't know the name of the big speaker, he only knew that it was much more powerful than the already advanced system.
When it comes to lf3, Li Zhuang has a dark heart. His broken computer cost less than 2 million, but he sold it to the factory for 8 million, including the labor of his intelligent production laboratory, which currently only has an automated construction project team. The cost is only a little over two million. The equipment and hardware modification costs for manufacturing the expert system are all paid by the factory. Even so, thirty sets have been sold, but they are all concentrated in the inner circle of Director Yang and Brother Liu. People outside who have money cannot buy them.
Li Zhuang doesn¡¯t want Big Speaker to be involved in the management of the lithium battery factory. He Xiuwen has been using large speakers to conduct super experiments during this time. The ultra-precision experimental expert system can indeed greatly improve the efficiency of experiments. In just one month, He Xiuwen came to the experimental conclusion that would have taken several years to complete.
Lithium battery factories will be a place of right and wrong in the future. Energy is really a headache. Even if it is too bad, it will not be competitive; ordinary profits are not high; power battery modules are very profitable. If the capacity is increased too fast, it will undoubtedly trigger the prying eyes of commercial espionage.
He Xiuwen is a very rigorous person, but he does not understand the industrial foundation as well as Li Zhuang, and the technical difficulties are probably not enough, so what he says is inevitably discounted. It was not until the end of November that the entire joint research team completed all the production processes, required equipment and modification parameters. This is the highest efficiency that a super team of nearly 60 people can achieve, with tens of millions invested in equipment and instruments, more than 20 Ph.D.s, and nearly 30 masters to increase the efforts of the super assistant of the loudspeaker.
"The basic level in China is really poor." Li Zhuang thought of this and wondered whether it was necessary to establish a new equipment manufacturing system in the industrial zone. When the joint research team encountered unsolvable difficulties, Li Zhuang and his apprentice Lu Tong took matters into their own hands and managed to modify some equipment.
Fully realizing the pain of searching for equipment and suitable instruments everywhere, he had to call Li Hui again: "Director Li, it's me, Li Zhuang."
The output value of the development zone has increased significantly this year, and it has become the most important industrial zone and the largest tax source base in K city. Li Hui was promoted to deputy director of the deputy division-level management committee last year, but is unable to be promoted for the time being. The deputy mayor in charge of industry is also the secretary, but he basically does nothing. The newly transferred director felt uncomfortable, but there was nothing she could do about it. She had brought all the people in the industrial area here and they only recognized her. Of course, the power of her family is the most important factor. Her uncle is the deputy governor in charge of industry and visited the industrial zone last month.
"Mr. Li, hello, hello. I, the little director, am nothing in front of you, let alone a deputy," Li Hui said with a smile.
Time is always tight in Lizhuang, and acquaintances are too lazy to be polite and get straight to the point: "I think there is still an equipment and instrument industry missing in the city. Is there any place that can be expanded? It is very inconvenient for me to change the equipment here."
¡°As long as you want to continue to expand, space is not a problem. We don¡¯t have many aborigines here,¡± Li Hui said.
"That's good. By the way, you said last time that some relatives in the city government want to invest. I already have some technical reserves in hand. You can tell them. If they are interested, they can come to our administrative building to talk. "
"Okay, I'll bring them here tomorrow."
How to grade? Li Zhuang felt that he needed to talk to He Xiuwen and others about how to maximize profits.
Meeting room in the administrative building.
When Li Zhuang came in, the joint research team was already seated. Seeing Li Zhuang come in, He Xiuwen handed him a detailed report.
The more Li Zhuang looked at it, the more he felt that he had underestimated them. These elites were very devoted to research and were not stupid when thinking carefully.
The recommendations of the joint research team are as follows:
? 1. Implement technology grading, and first provide information comparable to foreign levels to factories that are willing to invest. The patent legal department is already processing it. Achievements that exceed too many levels will not be patented for the time being, and will be kept in the laboratory for small-scale trial production. After gradually improving the process flow and equipment manufacturing, they will be gradually provided to them in order to maximize profits and protect the technical secrets of the laboratory.
2. Invest in establishing the laboratory¡¯s own equipment manufacturing industry. It does not need to be large-scale in the initial stage, as long as it can meet the needs of existing equipment modifications, and mass production will be gradually achieved in the future.
3. It is recommended to establish a complete industrial chain of lithium battery positive electrodes, negative electrodes, electrolytes and separator papers locally, and at the same time authorize one or two factories in other areas to expand coverage and reduce attention. Diaphragm paper requires major investment and is very complex.
4. For power battery modules, we will first provide some samples to automobile companies in the province, produce them in small batches, limit supply, and gradually expand production. Later, we will slowly improve performance according to the market, maximize practicality, and reduce costs.
These people were quite thoughtful, so Li Zhuang felt there was no problem. In terms of details, the Legal Affairs Department and the General Affairs Department need to carefully consider them to fill loopholes and reduce risks as much as possible.
"Battery endurance, price, policy, and interest group interference must all be considered. We originally discussed mild hybrid and full hybrid solutions, and the pure electric aspect will be used as a demonstration first. Dr. He, do you have connections in the automobile company? I saw that the province The largest car companies in the country are developing electric buses and electric cars."
As soon as Li Zhuang finished his words, He Xiuwen laughed "hehe". He felt confused and asked, "Is there any problem?"
"Li Zhuang, how big do you think the lithium battery circle is? I only need to find two people to cover all the R&D units in the province. The directors of several units all graduated from three schools in the province. The circle is very small. of.???Now we want to sell all types of lithium batteries, as long as they can make money. I asked my uncle and others to continue to expand investment. We now have reserves. In the future, we can sell technology and products. Anyway, we can sell whatever we have. "
Li Zhuang was speechless and didn't know what to say, but in the end he emphasized, "Don't set the price too low, otherwise the sales volume will not increase, and the future of electric vehicles will be far away."
"I know, I've been playing this for a long time and I'm good at it, so don't worry." He Xiuwen was full of confidence.
After the meeting, Li Zhuang found Zhang Kai and asked about the preparations for the business department, saying that this department must be established as soon as possible.
"Don't worry, I'm ready, everyone has been found." Zhang Kai couldn't help but despise this guy who was a bit arrogant in his work. He thought earlier than Li Zhuang. When the joint research team was reorganizing the lithium battery project, he had already found it. Picked the candidate. One of his high school classmates, named Wang Zhijie, was the sales manager of a battery company in the south. He had rich experience in this industry. Zhang Kai hired him as the deputy manager of the business department, responsible for the sales and contact of battery technology and related equipment, and worked with Brother Liu works with the sales manager of Qidong lithium battery factory.
Wesen Technology¡¯s current scale is not small among domestic R&D companies. Wang Zhijie didn¡¯t know much about the actual situation before coming here, and he was a little reluctant to come. He now earns a good income. For Zhang Kai's sake, he reluctantly came once. After learning about the actual situation of the company, he had no intention of leaving. Instead, he asked Zhang Kai to help him secure this position.
He Xiuwen was not bragging. In fact, the energy of the joint research team was far greater than Li Zhuang imagined. In less than two weeks, Zhou Qisen, tempted by Wesson Technology¡¯s power lithium battery samples and power management system, signed a dozen cooperation agreements with three automobile companies in the province, and will work with them to develop, fully hybrid and pure electric vehicles. .
The addition of new talents means fresh blood, which is a good thing. It is also a good thing that the gap can be opened smoothly in the energy field.
Li Zhuang was very happy during this period. He became a father and had a son.
When Li Zhuang arrived at the Central Hospital, he was still thinking about what his son would look like, like him or Lisa. When we arrived at the hospital, we found out that he was a beautiful mixed-race child, more like Lisa, but his eyes and outline still resembled his. What he is most proud of is having a pair of bright big eyes, and now he has just inherited it.
Li Zhuang, who was carrying his son around like an ordinary father, thought of another child he was about to give birth to. What should he name it?
As for the name of the super loudspeaker that was originally planned, I don¡¯t dare to think about it now. Let¡¯s not say whether Lisa agrees or not. It is estimated that the big and small speakers will have to argue and rearrange the seats. If it was arranged, he would probably have to filter his brain again. He was tired of being called wrong all the time.
At the end of December, when Li Zhuang was rushing to manufacture the lf3 needed by Liu Ge's factory on the 16th floor, he received a call from Liang Can.
"Azhuang, it's me. I'll arrive at the provincial capital international airport tomorrow. You can arrange for people to pick me up. There should be about twenty of them. Remember, I want to make your master look good!"
