Chapter 308 Done The preparation of graphene has been improved. After several adjustments, Lu Shan finally determined the specific process. We had originally planned to conduct the graphene battery assembly experiment right away, but the end of the year was approaching, and the graphene battery model and performance were a bit inconsistent, so we had to let the people in the factory go home and wait until after the New Year. Lu Shan has very high requirements for graphene batteries. The requirements for battery density, charging speed, volume and weight are far beyond existing products. According to comprehensive judgment, the performance requirements proposed by Lu Shan are more than fifty times that of lithium batteries on the market. After achieving these performance indicators, absolute safety is also required. With such high requirements, calculations and small experiments are naturally full of problems and errors often occur. Fortunately, Lu Shan was not discouraged. After all, things were moving in a good direction, so he just made adjustments little by little. Suddenly he thought of something, so he quickly contacted Wang Leiming. "Year-end bonus?" Wang Leimin was very surprised. It seemed that this factory had been established for less than a year? The factory was only established in the second half of the year, and it didn't produce anything, so where would the profit come from to pay out year-end bonuses?
No matter what he thought, Wang Leimin still listened to Lu Shan's arrangements and asked everyone to gather together. It was already the 20th day of the twelfth lunar month. Normally, people in Xia would go to work on New Year's Eve and then take a holiday until the 3rd day of the New Year. Departmental places have a longer work schedule, that is, New Year’s Eve or New Year’s Eve is postponed to the seventh day, and work resumes on the eighth day. That's all the time in a year. If you are from another place, you have to spend three or four days on the road. How can you celebrate the New Year? So Lu Shan had already clearly defined the holiday time, which is seven days before and eight days after the New Year, a total of half a month. He had to leave some time to go home and clean the house, right? When they heard that there would be year-end bonuses, Liang Wenping and others were surprised...but they didn't have too high expectations. They had been working there for too short a time and the factory hadn't sold anything, so it didn't seem like they deserved any year-end bonuses. The usual salary was already more than enough. Lu Shan looked at everyone and apologized to them: "I'm sorry, I should have distributed it to everyone a few days ago, so that you would have time to buy some New Year's goods and make other plans." Everyone was silent after hearing this. In my previous company, it was considered good to receive the year-end bonus on the 25th day of the twelfth lunar month. Lu Shan actually planned to send it out before the 15th day of the twelfth lunar month. He is so considerate. "I won't take up too much of your time here. Here are the list of names and the amounts to be distributed. If you work hard next year, you will definitely get more!" After saying that, Lu Shan handed the list to Zhang Leiming and left. Lu Shan also has to go to other companies to finalize the year-end bonus. Everyone has been busy for a year, so I have to say a few words about this, express my gratitude, and give some encouragement. It's not easy for anyone. Since Lu Shan left so quickly, people like Zhang Leimin and Liang Wenping subconsciously thought that his year-end bonus must be very low. When they opened it, they were all stunned. It's not too little, it's too high. Zhang Leiming received 30,000 yuan, Liang Wenping received 20,000 yuan, and the others received about 10,000 yuan. You know, this is only half a year. If it were a whole year, everything would have to be doubled. "This is not good..." The honest Liang Wenping was a little confused, and the even more honest Zhang Leiming was even more confused, but they finally decided to give out the money. After receiving his year-end bonus, Lu Shan hurried into the Singularity Laboratory to continue providing feedback on unexpected parameters.
Turing adjusted the model, Marie continued to improve the technology, and Poincare made sure the mathematical logic was correct and changed the logic as the technology changed. Finally, the work was done on the 26th day of the twelfth lunar month. Lu Shan stretched comfortably and finally returned to Jiangcheng County. After returning home, Lu Shan took the initiative to help his parents clean the house. They had been busy outside for a year and only had time to go home at this time. Sometimes, Lu Shan thought about calling it a day in this life. After all, the three companies were enough for him to live a worry-free life. No matter how much he achieved, it would still be a lifetime. So why work so hard? On second thought, the existence of the Singularity Laboratory is a mysterious thing. Why did it appear and where will it lead human civilization? Seeking answers to these questions is the meaning of life. If you have money, you can play all the time, but what if you get tired of playing all the games? What will they do? Most likely they will fall into depravity. That girl island, those outrageous quirks, are all tied to the richest people. Lu Shan is not very interested in these things, and exploring the world is more attractive. If you can watch the world change and become better because of your efforts, that sense of accomplishment is greater than just lying down and doing nothing. While he was daydreaming, Lu Dehai slapped him in the face: "I'm talking to you! Why are you daydreaming?" "Hmm? Oh!" Lu Shan realized that he was distracted. Lu Shan rarely gets distracted. He usually has something to do and is very focused. Perhaps it was because he was back home and the atmosphere was relaxed, so he didn't have so many things on his mind, and his mind was free. "Oh what! I'm asking you something." Lu Dehai frowned. Why was his son still in a daze? Was he working too hard? "What did you ask just now?" "Asking you when you'll bring your girlfriend home!" Lu Dehai said unhappily, "The son of the family next door has already brought his girlfriend home." "Ah? This is too fast." Lu Shan hesitated, "I haven't had time to think about this." "It's time to think about it." Lin Yan said softly at this time, "We can rest assured if you find someone who knows how to take care of you. You are so busy outside, and you don't know how to take care of yourself." "I'm not that fragile. I've always been healthy!" Lu Shan responded with a few words and then changed the subject. After the meal, Lu Shan also sighed that he had finally reached the age where he was urged to get married. Just now, Lin Yan actually said that someone came to introduce a girl to a blind date. Are people in this era so anxious? Suddenly I remembered some news and rumors I had read before, saying that college students would go on blind dates when they returned home during the holidays, and the right people would even continue to study after getting married and having children. However, Lu Shan did not agree with this, and it was better for him to concentrate on his studies. The choices you make when you are too young may not be the right ones. Moreover, it is difficult to concentrate on your studies when you have children and a family. If you see the upper limit of your scientific research, getting married and having children is understandable. "Well, I've recently started a new project. I'll consider it after I'm done with this busy period." Lu Shan said it very tactfully. Lin Yan knew that he was trying to comfort her. I couldn't help but nag him a few more times to let him know that he should take care of himself and find someone to talk to if he felt depressed. "Okay! Okay!" Lu Shan knew that his parents meant well and agreed quickly. The days of the Spring Festival were very...ordinary, just like those of other Xia people. It is both tasteless and full of atmosphere, some new things appearing and some traditions slowly disappearing. The overall feeling is that everyone celebrates the New Year in a very hurry, as if they were just punching a check-in, and that's all that matters.
During the Spring Festival holiday, Lu Shan's house was crowded with relatives visiting. Lu Shan's parents couldn't accept everyone who came, otherwise they would have no time to celebrate the holidays every day. It was the first time that Lu Shan knew that his family had so many relatives. He had always thought that his family was a small family with few relatives. Later, when they were introduced, he realized that he had to use a mind map to understand the relationship between these relatives. The son of my brother-in-law from my great uncle's side, the daughter of my aunt's cousin... Lu Shan's ability is enough to win the Nobel Prize and the Fields Medal, but his logical ability almost forced him to develop software for kinship relationships. He had to push it bit by bit every time, which was so tiring. It would be better to just enter the relationship directly to get the name. It is true that if you are poor in a busy city, no one knows you, but if you are rich in the mountains, you have relatives. Relatives come here just to reminisce about the past, and then hope to register with Lu Shan, line up, and arrange their family's work and life. Everyone knows that Lu Shan is running a company, but they don't care how much money he makes from research, they just think that running a company means he must be rich. Lu Shan did not reject all of them, but selected people based on their qualifications. He gathered talented people regardless of their relationship with them. There was no need to do this for fame. Arrange what can be arranged, arrange what can be arranged, give those who can learn the opportunity to learn, and for those who really can't, let them practice more before trying again. In addition to relatives, more people came during this Spring Festival holiday from the media, including mainstream traditional ones, and more from personal media, such as bloggers. Jiyue pioneered the field of personal media, and now many people have started working as bloggers part-time or even full-time. This group of people naturally choose hot topics, and Lu Shan is a good choice, as he is already more popular than celebrities. Of course, Lu Shan's family would not let media people in, but other neighbors started this business. "Why don't we just move?" Lu Shan sighed. There are so many people in the corridor every day, and some people go out with their parents to interview. Life has been seriously affected. Lu Shan finally understood why rich and famous people would buy those villas and mansions, because they want to screen out the people around them. Lu Dehai objected, saying that as long as they had a house to live in, it would be enough. He also taught Lu Shan that although there were many people here, they just needed to keep a normal mind, not put on airs, and chat with others when they had time. After a while, there won't be so many people. Lu Shan followed his father's advice. Facts proved that his father's wisdom was quite correct. Gradually, he got used to the lifestyle of Lu Shan's family. As soon as the Spring Festival holiday was over, Lu Shan couldn't wait to go to the factory in Jiangzhou to prepare for the final production. As the official working day arrived, everyone got into work mode. On the tenth day of the first lunar month of the Chinese New Year, the atmosphere in the graphene experimental site was very tense and no one dared to speak. Today was the day when the graphene battery officially rolled off the production line and everyone was very nervous. Zhang Leimin, Liang Wenping and other people at the management level stood beside Lu Shan, with different expressions on their faces. The former wanted to see if his idea for so many years had any chance of success, while the latter thought that if it didn't work, he would have to learn from the people in Jiangyang Province and go to Nanyue Province to work. In essence, both hoped that Lu Shan's battery would succeed. Lu Shan was very relaxed. His previous improvements to the chemical vapor deposition method had fully proved how accurate his model was. Besides, the battery was not a temporary experiment. He had always done small experiments. Today, he was just putting the parts of the toy together. There was no need to be nervous. The workers were seen rolling the graphene material into a circle, stuffing it into a battery shell prepared in advance, and finally dripping in chemical liquid and then sealing the lid. The entire process is done manually. Because the batteries are relatively small and the production line is not yet precise enough, we can only do this for now. When the production line is upgraded in the future, it can be fully automatic. Everything can be prepared in advance, folded automatically, and sealed together with the outer shell. Not much chemical liquid is required, and it can be injected with a precise pressure injection head. Today's focus is to see whether graphene batteries can be used and how easy they are to use. The problems with production lines are slowly being solved. "It's offline, take a look!" Zhang Leimin handed the newly-produced graphene battery to Lu Shan with excitement. Lu Shan looked at the fingernail-sized graphene battery and felt quite satisfied. After all, it was rare to achieve this size. "Take it for testing." Lu Shan handed the graphene battery to Zhang Leimin without further ado. Zhang Leimin had been researching this for more than a decade, and now that he had finally seen the real thing, he was more excited than anyone else. Testing takes time, and the testing method is not difficult. Basically, we produce a few samples and use one to test whether the voltage is sufficient. This can be directly installed on the mobile phone to know whether it can be adapted or not. Some modification and conversion are required.
One is to check the power, the other is to check the charging efficiency. One is to check the safety, that is, to see whether it is drop-resistant, flame-retardant, what happens at low temperatures, and what happens at high temperatures. Anyway, just put it in the mobile phone and watch it, and record the data on the testing instrument. The other data detections were quite slow, but the charging detection was quite fast since it was not charged at the beginning. "It only takes ten minutes to fully charge, and the battery capacity is up to 20000 mAh!" "Okay, got it." Lu Shan thought about it for a moment. According to the current battery architecture that leaves room for improvement, if the performance can be squeezed within a safe range, the maximum capacity can reach 30000 mAh. However, there is no need to reach this level. The market cannot be oversaturated all at once. Besides, even if it is 15000 mAh, it is worthy of consumers. Nowadays, even Nokia's DIY battery can only reach 2000 mAh. In comparison, the gap is too obvious. Even after more than a decade, when large-screen smartphones are everywhere, the battery capacity is only around 6000 mAh. Because the phone is so small and thin, the battery has to be so big, and it is considered amazing if it can reach 8000 mAh. A 20000 mAh battery is consumed bit by bit over a long period of time, so I could only do a brute force test, turning on the phone's flashlight while keeping the screen on. It took me three days to finally get electricity working. Lu Shan was very satisfied. Even if smartphones became popular in the future, he could use it for two days without stopping, which saved him a power bank. Later, everyone kept a power bank with them, and Lu Shan himself was no exception. It was really too frustrating. After going out for a day, the phone could not be fully charged, and the experience was too bad. (End of this chapter)
