Chapter 150 The Perovskite Battery Craze
After the meeting, Yang Jiashan could not calm down for a long time. We are all human beings, why are you so showy?
He is very aware of the genius level of his boss. The person who can create room temperature superconductivity is definitely not an ordinary person. He is a top scientist spanning multiple fields of biology, chemistry, and physics.
But you are a bit too supermodel. The last time the Trailblazer 2 exploded was two weeks ago. Two weeks ago, you gave us an idea and asked us to design it. At least in Yang Jiashan’s plan It will take three months to optimize the Vulcan engine according to Chen Yuanguang's ideas.
But what did he see now? It only took Chen Yuanguang two weeks to come up with a complete rocket design plan. All the parameters were clearly stated for you. They only needed to do the feasibility. To verify, do ground tests.
And as an expert in the field of rocket engines, he can clearly see that the version of the plan given by Chen Yuanguang cannot be considered an optimization at all. It is a completely new engine design plan, with almost no trace of the Vulcan engine.
Whether it is staged combustion, external storage tanks, separation and recovery, etc., how can these rocket design ideas that have only been developed in the past ten years be the same as those on the Vulcan engine thirty years ago.
Yang Jiashan can also see the completeness of this plan. All the parameters are marked. Can it be incomplete?
It's like Falcon 9 copied and pasted its own engine design directly to you, with all the data clearly marked.
Yang Jiashan never thought about where Chen Yuanguang got this plan, but the application of the ablative nozzle in it made his eyes shine. It was completely designed to meet their needs.
Because the level of suppliers is uneven, multi-engine bundling may encounter the problem of uneven thrust. Adding ablative nozzles reduces the amount of parts and manual work to achieve the purpose of centralizing suppliers. Such a design idea whether it is SpaceX or Locke Neither Dyne nor ULA can be seen, let alone Europe.
If Europe had this level, it would not be so desperate that it would buy recyclable rocket launch technology from them.
If there is no other rocket engine design idea in adding ablative nozzles, then using an external storage tank to control the amount of low-temperature hydrogen and oxygen propellant to achieve the effect of controlling different engine thrusts, then It was completely Chen Yuanguang's own idea.
It is precisely because various signs prove that this engine came from Chen Yuanguang that Yang Jiashan feels so frustrated. He is also from the junior class of Xi'an Jiaotong University. He graduated with a doctorate in his early twenties, but under Chen Yuanguang Being vulnerable in front of others, in the field that I have been engaged in all my life, I am not as good as playing cross-border.
"Tianmin, boss, has he always moved so fast?" Because he had only joined Guangjia Aerospace for a shorter period of time, he came to Lin Tianmin and wanted to know from him what Chen Yuanguang was like in his early stages.
Lin Tianmin knew what the other party was shocked about, and he was equally shocked, but he was a little better than Yang Jiashan, "The boss also had a period of time when Guangjia Aerospace just started. He did everything himself, and then everyone only needed to do verification and Calculation work is enough.
But I haven’t seen the boss do this again for a long time. Later, we were allowed to do whatever we wanted.
It was probably because the Pioneer 2 launch failed and we were a little bit frustrated. It was exciting, so I started doing it myself again, and everyone did some auxiliary work.
This can be said to be a kind of path dependence. I never missed it, but when someone else took over and something went wrong, they would naturally respond habitually. On the previous path."
Lin Tianmin realized that he had said something wrong and quickly added: "Team leader, I didn't say what you meant. I was just explaining why the boss was so anxious and took it out himself. A set of plans, rather than letting everyone design it as we said in the previous meeting.”
Lin Tianmin felt that he was getting darker and darker, so he simply shut up and stopped talking.
After hearing this, Yang Jiashan patted the other party on the shoulder, thinking that you kid would still hint, "I know you don't mean it.
We should divide it into two groups and do it in one wave. Verification, the other wave will continue to design the engine according to our original plan. "
What Lin Tianmin can think of, Yang Jiashan can also think of, everything needs to be done by the boss, so what is your role?
Lin Tianmin, a newly graduated doctoral student, can accept to do some auxiliary work and accept that he will slowly grow in the process, but he cannot. He joined Light Armor Aerospace as an expert.
If he also does some auxiliary work, then why is his existence necessary?
So Yang Jiashan chose to walk on two legs. He hoped to design a better engine than his boss to prove his worth.
On the other hand, Lin Jia, who had presided over the opening ceremony of the Human Hibernation Center, flew to Mianyang to see Chen Yuanguang.
“Mianyang is more developed than I thought. Even Suzhou doesn’t have an airport, but there is a direct airport.” Lin Jia beamed after seeing Chen Yuanguang.
When Chen Yuanguang and Lin Jia hugged, he was thinking that hugging Shi Huilan in the future would not be considered cheating. "It's not bad here. It allowed me to see the comprehensiveness of China's infrastructure.
Third-tier cities still have infrastructure levels that are no less than those of first-tier cities.
I am quite used to it. China has provided me with first-class scientific research facilities here. I can also visit and even use some laboratories in sensitive fields here.
I don’t even want to go back to Shen Hai. "
Lin Jia said with emotion: "Is this why I am happy to miss Shu? "
"Isn't the building we took across from the west area of Huashan Hospital in MH District used as a human hibernation center? At the opening ceremony this morning, because it is jointly operated by Huashan Hospital and us, Shenhai officials also sent leaders to attend. They were still asking when you would return to Shenhai.
The leaders at Shenhai are very concerned about you, including the establishment of a superconducting research center at Jiaotong University, and they hope to ask you to be the dean.
By the way, Jiangcheng University wants to award you an honorary doctorate. They hope to discuss strategic cooperation with Guangjia Aerospace. I hope we can go to Jiangda to recruit more people. ”
Generally speaking, company founders will have a preference for their alma mater and will recruit more people from their alma mater, such as Xiaomi from Jiangsu University, Echang from Pengcheng University, and Ali also prefers local students from Zhejiang. .
But because of the special nature of Guangjia Aerospace, the majority of them are students from major aviation colleges, but the proportion of students from Jiang University is not large
at Normal Temperature. Before the discovery of superconductivity, everyone thought it was nothing, and Jiangda was not very enthusiastic about it. After all, Jiangda did not have an advantage in the field of light armor aerospace.
Things are different now. The halo of Guangjia Aerospace has been added. Some private organizations have calculated the ratio of employees in Guangjia Aerospace to universities. The proportion of Jiangda University is very low. This is ridiculed by netizens because the level is not good. The leaders of Jiangda University couldn't bear it after seeing it. Zhang Yi quickly contacted Lin Jia. Zhang Yi is the director of the Resource Development Office of the Jiangnan University Alumni Affairs and Development Liaison Office mentioned earlier.
Chen Yuanguang said: "No problem. We also need to recruit a lot of comprehensive talents, not just in the aerospace field. In fact, we have a lot of experience in materials science, condensed matter physics, chemistry, and mechanics. There is demand in these fields."
Lin Jia nodded, "I think so too, mainly because of the company name, and because we have frequently launched rockets to the outside world before, people think that we are an aerospace company. The main company only recruits students majoring in aerospace, and the recruitment promotion is far from enough. "
This is a fact. Light Armor Aerospace is both a recyclable rocket and a space station, and it even needs to. To cultivate their own astronauts, their image to the outside world is no different from that of SpaceX. Even if room temperature superconductivity breaks through the circle on a global scale this time, room temperature superconductivity is regarded more as the contribution of Chen Yuanguang rather than the light armor aerospace industry. .
Therefore, most of the resumes received by Guangjia Aerospace during recruitment are more or less related to aerospace. Some have undergraduate degrees in aerospace and have switched to other directions during their postgraduate studies. Some have switched to aerospace as postgraduates, and some have been in aerospace. In major categories.
The outside world still believes that universities like Jiangnan University have realized that Guangjia Aerospace has an urgent need for almost all science and engineering students, so they hope to establish a closer connection with Guangjia Aerospace.
Lin Jia continued: "Then Tesla wants to talk to us. They hope to obtain authorization for the second batch of perovskite batteries. It is said that Musk cannot stand that his Cybertruck does not have Perovskite battery blessing.
After the MPVs of Ideal and Xpeng were announced one after another, the energy supplement function of perovskite batteries was the focus of their promotion.
Xpeng X9 has been released. Perovskite batteries are rare battery products that actually increase battery life more than theoretically.
Musk reposted a video of a YouTube technology blogger reviewing the Xpeng X9 on Twitter, saying that their Cybertruck will also be equipped with perovskite battery technology.
Although they haven't reached a conclusion yet, Musk's words have been released. Their executives in Greater China are very eager and would rather compromise on the patent licensing price. ”
At the Xpeng X9 launch conference not long ago, they promoted perovskite batteries as a highlight.
Because the X9 is an MPV similar to the Toyota Alpha, it feels a bit like a van. , so its body is very long, and the overall roof is a flat surface, which is very suitable for adding solar cells on it.
Traditional crystalline silicon cells have limited photoelectric conversion efficiency, and the light intensity reaches a certain level. , the photoelectric conversion effect will take effect, and light energy will be converted into electrical energy
Many car companies have made attempts in the past, including Liangtian, but they were limited by solar cells and did not achieve good results.
This time, with the support of perovskite batteries, Xpeng X9 is no longer useless, but a must-have configuration.
Yes, the perovskite battery is an optional feature for the Xpeng X9, which costs 20,000 yuan.
According to the offline data collected by Know Car Di, more than 70% of car buyers have purchased this feature.
Not only did Xpeng hype this feature at its own press conference, but many car reviewers also promoted this feature as a rare highlight.
Some car reviewers drive the Xpeng X9 for long distances just to test the battery life of the perovskite battery: “Xpeng X9 itself advertises that their perovskite battery can provide them with a battery life of more than 200 kilometers. The local lighting conditions have fluctuated. Today we drove the Xpeng X9 from Shenhai to Pengcheng to test how powerful its perovskite battery is.
I ran 200 kilometers, and its battery management module showed that of the 200 kilometers, 50 kilometers were run on the power provided by the perovskite battery, which is 25%. Of course, this has sufficient light.
We were in a charging state just now. After four hours of charging, the perovskite battery can now provide 50 kilometers of battery life, which means that it can provide 50 kilometers of battery life in four hours. , then even if the car runs out of battery, we only need to park it in the sun for most of the day to restore a little battery life and let us run to the nearest power station. Can you bear this?
Xpeng X9? The price is definitely a qualified MPV. With the blessing of perovskite batteries, it has no shortcomings. In the past, we would worry about such a large MPV. We may need to use it at any time. What should we do if the battery runs out? What to do if you forget to charge.
Now I think solar accelerated charging is a particularly good solution. I estimate that its real battery life is over 800 kilometers. The rational Mega is nervous. ”
The result is that this group of self-media can replenish energy for nearly 250 kilometers under sufficient light.
You must know that this is an MPV with an amazing weight and volume. This data is in the publicity The level has even gone out of the circle
This has also made many new energy car companies realize that only range extension can solve users’ battery life anxiety. Now there is a new option, which is perovskite batteries. .
As the first to hit the market, the Xpeng X9 is priced at RMB 300,000 to RMB 400,000, making it the most expensive among the Xpeng series. It has been the best-selling model since its launch, with sales volume ranking second among MPVs. Ranked first in the category
Foreign countries, especially places with sufficient sunlight such as Southeast Asia, South America, Africa, and Kangaroo Country, are quite enthusiastic about the Xpeng X9. Among them, dealers from Southeast Asia and Kangaroo Country have already come to discuss cooperation.
Chery, which sells the best products abroad, their long-term partners also came to them and asked if they had any models equipped with perovskite batteries. This is a hot topic for knowledgeable new energy vehicle consumers. .
At the same time, perovskite cells are a powerful export tool for Chinese companies in the field of new infrastructure. Originally, China’s photovoltaic module exports relied on price wars. With the blessing of perovskite cells, China’s photovoltaic Enterprises have established price alliances and raised prices in a unified manner in order to reap this wave of price dividends.
Including Chinese infrastructure companies, they have received many large orders for photovoltaic power stations in Europe, Kangaroo Country and Maple Leaf Country.
The direct output value brought by perovskites has exceeded 500 billion RMB, which has also triggered a hype boom in Big A.
Compared with China's new energy vehicles, Tesla has gradually lost its advantage. It can sell better than China's new energy vehicles overseas mainly because of its first-mover advantage. Once China's new energy vehicles have special characteristics, The first-mover advantage will be offset by the long board that Sla cannot match.
No wonder Musk is anxious.
