Chapter 150 Perovskite Battery Boom

After the meeting, Yang Jiashan couldn’t calm down for a long time. We are all human beings, why do you have to be so showy?

He was well aware of the genius of his boss. The one who could create room-temperature superconductivity was definitely not an ordinary person. He was a top scientist in multiple fields including biology, chemistry and physics.

But this is a bit too much. The last explosion of Pioneer 2 was two weeks ago. Two weeks ago, you gave us an idea and asked us to design it. According to Yang Jiashan's plan, it will take at least three months to optimize the Vulcan engine according to Chen Yuanguang's idea.

But what he saw now was that Chen Yuanguang had only spent two weeks to come up with a complete rocket design plan, with all the parameters clearly marked out for him. They only needed to do feasibility verification and conduct ground tests.

Moreover, as an expert in the field of rocket engines, he could clearly see that the plan given by Chen Yuanguang could not be considered an optimization at all. It was a completely new engine design plan, and there was almost no trace of the Vulcan engine.

Whether it is staged combustion, external tanks, separation and recovery, etc., these rocket design ideas that have only appeared in the past decade, how could they be something that was on the Vulcan engine from thirty years ago.

Yang Jiashan could also see the completeness of this plan. All kinds of parameters were marked out. How could it be incomplete?
It’s as if Falcon 9 directly copied and pasted its own engine design plan for you, with all the data clearly marked.

Yang Jiashan had wondered whether Chen Yuanguang got this solution from somewhere, but the application of ablative nozzles in it caught his eye, as it was designed entirely according to their needs.

Because the quality of suppliers varies, bundling multiple engines may encounter problems with uneven thrust. Adding ablative nozzles will reduce parts and manual workload to achieve the goal of concentrating suppliers. Such a design idea is not seen in SpaceX, Rocketdyne, or ULA, let alone Europe.

If Europe had this level, it would not have fallen to the point of having to buy reusable rocket launch technology from them.

If adding the ablative nozzle does not show any other rocket engine design ideas, then using an external tank to control the amount of cryogenic hydrogen-oxygen propellant to achieve the effect of controlling different engine thrusts is completely Chen Yuanguang's own idea.

It is precisely because all the signs prove that this engine came from Chen Yuanguang that Yang Jiashan feels so frustrated. He is also a graduate of the junior class of Xi'an Jiaotong University and graduated with a doctorate in his early twenties, but he is no match for Chen Yuanguang in the field he has been engaged in for a lifetime.

"Tianmin, has the boss always moved so quickly?" Because he had joined Guangjia Aerospace for a shorter time, he approached Lin Tianmin, wanting to learn from him about what Chen Yuanguang was like in the early stages.

Lin Tianmin knew what the other party was shocked about, and he was also shocked, but he was better than Yang Jiashan, "When the boss first started Guangjia Aerospace, there was a period of time when he did everything himself, and then everyone only needed to do verification and calculation work.

However, I haven’t seen the boss do this for a long time. From now on, he lets us do whatever we want.

I guess it was because of the failure of the Pioneer 2 launch that they were a bit upset, so they started to do it themselves again, and everyone did some auxiliary work.

This can be said to be a kind of path dependence. I have never missed a thing, but when problems arise after others take over, they naturally return to the previous path out of habit. "

Lin Tianmin realized that he had said the wrong thing, and quickly said, "Team Leader, I didn't mean what you said. I was just explaining why the boss was so anxious to come up with a plan himself, instead of letting everyone design it as he said in the previous meeting with us."

Lin Tianmin felt that the more he explained, the worse the situation became, so he simply shut up.

After listening to this, Yang Jiashan patted the other person on the shoulder, thinking that you are still good at hinting, "I know you don't mean that.

We still divided into two groups, one to do verification, and the other to continue designing the engine according to our original plan."

What Lin Tianmin could think of, Yang Jiashan could obviously think of as well. If the boss has to do everything, then what is your role?
Lin Tianmin, a newly graduated doctoral student, can accept doing some auxiliary work and slowly grow in the process. But he can't. He joined Guangjia Aerospace as an expert.

If he also does some auxiliary work, then what is the necessity of his existence?

Therefore, Yang Jiashan chose to walk on two legs. He hoped to design a better engine than his boss to prove his own value.

On the other hand, Lin Jia, who 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 here there is an airport with direct access." Lin Jia smiled after meeting Chen Yuanguang.

When Chen Yuanguang and Lin Jia were hugging, he was thinking that hugging Shi Huilan in the future should not be considered cheating, "This place is not bad, it allows me to see the comprehensiveness of China's infrastructure.

The infrastructure level of third-tier cities is still no less than that of first-tier cities.

I am quite used to it. China has provided me with first-class scientific research facilities here, and I can also visit and even use laboratories in some sensitive areas.

I don’t even want to go back to Shenhai anymore.”

Lin Jia sighed: "Is this what it means to be happy here and not miss your homeland?"

"Isn't the building we took across from the West District of Huashan Hospital in MH District used as a human hibernation center? At the opening ceremony this morning, because Huashan Hospital and we jointly operated it, Shenhai officials also sent leaders to participate. They are still asking when you will return to Shenhai.

The leaders of Shenhai University are very concerned about you, including Jiaotong University, which is going to set up a superconductivity research center and hopes to invite you to be the dean.

By the way, Jiangcheng University wants to award you an honorary doctorate degree. They hope to discuss strategic cooperation with Guangjia Aerospace, and hope that we can recruit more people from Jiangcheng University."

Generally speaking, company founders have preferences for their alma mater and will recruit more people from there, such as Xiaomi recruited from Jiangnan University, Tencent recruited from Pengcheng University, and Ali also prefers local Zhejiang students.

However, due to the special nature of Guangjia Aerospace, the majority of their students come from major aviation colleges, while students from Jiangnan University do not account for a large proportion.

Before the discovery of room-temperature superconductivity, everyone thought it was nothing, and Jiangnan University was not very enthusiastic about it. After all, Jiangnan University does not have an advantage in the field of light armor aerospace, which is its main business.

Now it is different. With the halo of Guangjia Aerospace, some private institutions counted the proportion of college graduates in Guangjia Aerospace, and Jiangnan University had a very low proportion. Netizens joked that it was because of its poor quality. When the leaders of Jiangnan University saw this, they couldn't help but asked Zhang Yi to contact Lin Jia as soon as possible. Zhang Yi is the director of the Resource Development Office of the Jiangnan University Alumni Affairs and Development Liaison Office mentioned above.

Chen Yuanguang said: "No problem. We also need to recruit a lot of comprehensive talents, not just in the field of aerospace. In fact, we have demand in the fields of materials science, condensed matter physics, chemistry, and mechanics."

Lin Jia nodded, "I think so too. It's mainly because of the company name. In addition, we frequently launched rockets to the outside world, which led people to think that we were an aerospace company and only recruited students majoring in aerospace. The efforts in recruitment publicity were far from enough."

This is a fact. Guangjia Aerospace has reusable rockets, space stations, and even trains its own astronauts. Their image in the outside world is no different from that of SpaceX. Even though room-temperature superconductivity has broken the circle on a global scale this time, room-temperature superconductivity is more seen as the credit of Chen Yuanguang rather than Guangjia Aerospace.

Therefore, most of the resumes that Guangjia Aerospace received during recruitment were more or less related to aerospace. Some had undergraduate majors in aerospace but switched to other majors during graduate school, some switched to aerospace during graduate school, and some have always been in the aerospace category.

The outside world still believes that universities like Jiangnan University have realized that Guangma Aerospace has an urgent need for almost all science and engineering students, so they hope to establish a closer connection with Guangma Aerospace.

Lin Jia continued: "Then Tesla wanted to talk to us. They wanted to get authorization for the second batch of perovskite batteries. It was said that Musk couldn't stand that his Cybertruck didn't have perovskite batteries.

After Ideal and Xiaopeng released their MPVs one after another, they used the energy-replenishing function of perovskite batteries as the focus of their publicity.

Xiaopeng X9 has been released. Perovskite batteries are rare, and the actual increase in battery life is greater than the theoretical increase in battery life.

Musk retweeted a video of a YouTube technology blogger reviewing the Xiaopeng X9 on Twitter, saying that their Cyber ​​​​Pickup will also be equipped with perovskite battery technology.

Although they haven't reached an agreement yet, Musk has already said that their executives in Greater China are very eager and would rather make concessions on the price of patent licensing."

At the launch of Xiaopeng X9 not long ago, they promoted perovskite batteries as a major highlight.

Because the X9 is an MPV similar to Toyota Alpha, and feels a bit like a van, its body is very long, and the entire 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 photoelectric conversion effect will only take effect and convert light energy into electrical energy when the light intensity reaches a certain level.

In the past, many car companies have tried this, including Toyota and Toyota, but they were limited by solar cells and did not achieve very good results.

This time, with the support of perovskite batteries, Xiaopeng X9 is no longer a useless thing, but a must-have configuration.

Yes, perovskite batteries are an optional feature for Xiaopeng X9, and it costs 2 yuan to install.

According to offline data collected by DoCar.com, more than 70 percent of car buyers have chosen this function.

Not only did Xiaopeng promote this feature at its own press conference, a number of car reviewers also promoted this feature as a rare highlight.

Some car reviewers drive the Xiaopeng X9 for long distances just to test the endurance of the perovskite battery: "Xiaopeng X9 claims that their perovskite battery can provide them with a range of more than kilometers, which fluctuates according to the light conditions in different places.

Today we drove the Xiaopeng X9 from Shenhai to Pengcheng to test how powerful the energy replenishment function of its perovskite battery is.

I ran 200 kilometers, and its battery management module showed that 50 kilometers of these 200 kilometers were powered by perovskite batteries, which is 25%. Of course, this was due to sufficient sunlight.

Just now we were in a charging state. After charging for four hours, the perovskite battery can now provide a range of 50 kilometers. That is to say, it can provide 50 kilometers of range in four hours. So even if our car runs out of power, we only need to park it in the sun for most of the day to restore some range and allow us to run to the nearest charging station. Can you bear this?

At this price, the Xiaopeng X9 is definitely a qualified MPV. With the support of perovskite batteries, it has completely eliminated its shortcomings. Before, we would worry about such a large MPV, which might be used at any time. What if the battery runs out of power? What if we forget to charge it?

Now I think solar fast charging is a particularly good solution. I estimate that its actual range is more than 800 kilometers. MEGA is getting nervous. Xiaopeng has made a good start. If you don’t come out, Xiaopeng’s first-mover advantage is likely to occupy your market. "

The result is that these self-media can replenish nearly 250 kilometers under sufficient light.

You have to know that this is an MPV with astonishing weight and volume, and this data has even gone viral in terms of publicity.

This also made a number of new energy vehicle companies realize that originally only the extended-range model could solve users' range anxiety, but now there is a new option, which is the perovskite battery.

As the first to take the plunge, Xiaopeng X9, with a price tag of RMB 30 to 40, is the most expensive model in the Xiaopeng series. However, it has been the best-selling model since its launch, ranking first in sales volume in the MPV category.

People in foreign countries, especially in Southeast Asia, South America, Africa, and the Kangaroo Country with abundant sunlight, are quite envious of the Xiaopeng X9. Distributors in Southeast Asia and the Kangaroo Country have already come to discuss cooperation.

Chery, which sells the best cars overseas, was approached by their long-term partners, asking them if they had any models equipped with perovskite batteries. This is a hot topic among knowledgeable new energy vehicle consumers.

At the same time, perovskite batteries are a powerful tool for Chinese companies' exports in the field of new infrastructure. Originally, China's photovoltaic module exports relied on price wars. With the support of perovskite batteries, Chinese photovoltaic companies have established a price alliance and uniformly raised prices 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, the Kangaroo Country and the Maple Leaf Country.

The direct output value brought by perovskite exceeded 500 billion RMB, which also triggered a hype in the A-share market.

Compared with China's new energy vehicles, Tesla has been gradually losing its advantages. The main reason why it can sell better than China's new energy vehicles overseas is because of its first-mover advantage. Once China's new energy vehicles have strengths that Tesla cannot match, the first-mover advantage will be offset.

No wonder Musk is anxious.
