A week later, Pang Xuelin once again appeared in New York on a special plane.

Pang Xuelin first went to the United Nations Building to meet with the new UN Secretary-General Dewey Clive and PDC's rotating chairman Pritt Leslie. After that, Pang Xuelin went directly to the Strategic Defense Board of the Planetary Defense Council not far from the UN headquarters.

"Director Vader, nice to meet you!"

"Professor Pang, is there anything wrong with me?"

Wade was obviously a bit surprised by Pang Xuelin's arrival, and went straight.

After five years without seeing it, Vader didn't seem to have changed much. He was holding a cigar, and the smoke shrouded his grim face.

Cheng Xin, who was behind Pang Xuelin, winked. Cheng Xin led his followers out of Wade's office, and had not forgotten to bring the door before leaving.

Pang Xuelin stepped forward, casually pulled the swivel chair in front of the desk, sat down opposite Vader, and laughed: "Mr. Vader, five years ago, I asked you if you would like to work in the office of the walled person. You choose I refused. Now, I would like to ask, would you like to work in the Galapagos Islands? As long as you are willing, you are the chief executive officer of Starring City, Starring City and Starring Advanced Institute for the next 20 years All construction and development of yours will be led by you. "

Vader took a deep sip of the cigar, smoky, covering up the subtle changes in his face.

"why me?"

Vader coldly.

A member of the Wall's Office and the Star City Chief Executive Officer have completely different powers.

Today's Starring City, whether in academia or internationally, is a famous presence.

The only port city designated by the wallists has invested heavily in basic science. There are even rumors that Star Circle is preparing to develop controllable fusion technology.

Apart from that, the star PDC alone of up to 50 billion US dollars per year is enough to make anyone salivate.

Therefore, Wade seemed a little surprised by Pang Xuelin's sudden proposal to serve as the chief executive officer of Star Circle.

Pang Xuelin laughed and said, "I am very optimistic about you. In fact, I was optimistic about you five years ago. Your overall planning ability and firm conviction during the implementation of the ladder plan are all I need. In addition, I see ambitions in your eyes. I need someone like you to **** the Starring City, and the future of humanity also needs someone like you. I believe you can bring glory to the Starring City. And I listen to Vadim Say, you seem to be tired of the position of Director of PIA, and you want to go to the future through hibernation! I hope you can work for me for twenty years before hibernation! "

"Then what can you give me?"

There was no change to the watch on Vader's face.

Pang Xuelin said: "Absolute power! But there is a premise, I want you to complete all technical accumulation of controllable nuclear fusion, modern agricultural factories, and electromagnetic orbital space launch systems within twenty years!"

Wade frowned: "Professor Pang, your request is a bit high. I am afraid that the investment of 50 billion US dollars each year may not be enough."

Pang Xuelin smiled lightly: "How much profit do you think an ultra-high-density energy storage battery can bring to StarCity every year?"

"Ultra-high-density energy storage batteries?"

Vader's face was surprised.

Pang Xuelin nodded.

The ultra-high-density energy storage battery is naturally the kind of super battery brought from the wandering earth world.

Although in a short period of time, it cannot make rapid progress in human energy technology, it can profoundly change the global energy structure.

The three-body world can already mass-produce high-purity graphene materials on an industrial scale. It is not too difficult to manufacture super energy storage batteries in the stray earth.

In fact, in the three-body world, there is also the concept of graphene batteries.

But this is not an accurate concept. To be precise, basically, a little graphene is added to the material to improve the partial energy of the lithium battery. It can be called a graphene-based lithium ion battery.

In the laboratory, scientists have been able to increase the specific energy of graphene-based lithium-ion batteries to more than 600wh / kg, which is twice the current best lithium batteries on the market.

Moreover, this battery requires only 8 minutes for a single full charge, has a service life that is four times that of traditional hydrogen batteries, twice that of lithium batteries, and weighs only half that of traditional batteries. This is a revolution in the field of energy storage batteries. Breakthrough.

But this is just the data in the laboratory. It is basically dumb to the practical stage.

The reason is simple. First, the cost of all-graphene batteries is very high, and the preparation is difficult, and mass production is almost impossible. Some of the amazing data released now are basically graphene batteries with extremely high purity, which only appear in the concept stage or in the laboratory.

Secondly, the role of "doped graphene batteries" on lithium batteries is as a conductive agent or electrode-embedded lithium material, but compared with the traditional low cost of conductive carbon and graphite, the former can not improve the energy to attract manufacturers.

Third, the high specific surface area of ​​graphene materials is not compatible with the current technical system of the lithium ion battery industry.

In addition, issues such as the impact of other materials and the difficulty of dispersion processes have restricted the application of graphene in lithium batteries.

And in theory, the theoretical capacity of pure graphene anode materials is only 0.78KWh / kg, which is much better than the lithium batteries on the market, but compared with the theoretical capacity of 10kwh / kg of the legendary lithium-air battery, The two are not at the same level at all.

What Pang Xuelin wants to do is the official lithium air battery. In the stray earth world, it has a more accurate name, graphene-based lithium air battery.

Lithium-air batteries are not a new concept.

Since the oxygen in the air is used as the active material on the positive electrode, the theoretical capacity density of the positive electrode is infinite, and the capacity can be increased.

In addition, if the negative electrode uses metallic lithium, the theoretical capacity will be one digit higher than that of a lithium-ion rechargeable battery.

However, lithium-air batteries also have a fatal flaw, that is, lithium hydroxide, a solid reaction product, can accumulate on the positive electrode, and the contact between the electrolyte and the air is blocked, causing the discharge to stop.

In the wandering earth world, scientists have developed a two-dimensional graphene film with a large specific surface area, which allows lithium hydroxide formed by solid reactions to accumulate on the film, thereby solving this long-standing problem that has plagued the battery industry.

This technology is quite mature in the stray earth world, and in the three-body world, because of the breakthrough in the industrial production of high-purity graphene, as long as it continues to invest in this direction, Pang Xuelin expects to make such batteries in three years.

Wade was somewhat uncomfortable with the so-called ultra-high-density energy storage battery. After a moment of groaning, he looked up and said, "Professor Pang, I hope I can go to Star Circle to see if you agree with your request. The results seen down in Star Circle. "

Pang Xuelin laughed and said, "Welcome anytime!"

...

Down from the PIA headquarters, Pang Xuelin saw Cheng Xinzheng chatting with Vadim.

Seeing this modest aerospace engineer, Pang Xuelin was a little emotional.

If according to the original play, Vadim was already killed by Vader at this time, but now he still lives well and can see that his life is not bad.

"Cheng Xin, we should almost go!"

"Oh, okay, Brother Vadim, then I'll go first, and I'll get in touch later!"

Pang Xuelin and Cheng Xin got into the car. Cheng Xindao said, "Professor Pang, what did Director Wade say?"

Pang Xuelin laughed: "He said that he would follow me to Star Circle, if Star Circle meets his requirements, he would agree."

Cheng Xin nodded and didn't ask any more.

When the convoy returned to the Hilton Hotel, Pang Xuelin discovered that the hotel's security guards were much tighter than before.

When he got out of the car, he saw a UN official hurriedly greeted him and said, "Professor Pang, I'm Bryant, the liaison officer of Radiaz, who is a face-to-face. Radiaz wants to see you!"

Pang Xuelin couldn't help it.

He didn't have much contact with Rediaz. In fact, apart from the two round tables, the two had basically no contact in private.

Rediyaz is busy promoting the research and development of stellar hydrogen bombs every day, while Pang Xuelin takes care of his own Star Circle City. In addition, he has been hibernating in recent years, and the two have no intersection at all.

What did Rediaz find for himself at this time?

It is impossible to say that someone has cracked his strategic idea.

None of his stellar hydrogen bombs have been made, let alone that weird fear.

With such questions, Pang Xuelin met Rediaz in the reception room of the president's room.

"Hello Professor Pang!"

"Hello Mr. Rediyaz!"

The two shook hands for a moment.

Pang Xuelin opened the door and said, "Mr. Rediz, is there anything wrong with me this time?"

"I'm fine," Ladiaz laughed. "I just want to come and talk to you. I'm going to hibernate soon."

"Ok?"

"The stellar hydrogen bomb requires powerful computing power. The current level of supercomputers cannot support such a project. I can only wake up after the supercomputing is fruitful."

"So it is."

Pang Xuelin nodded.

Radiaz was silent for a moment and said, "Professor Pang, in fact, I knew that half a year ago, it was true ... Taylor and I are old rivals. I can guess what he thinks, and I believe he can also guess. It came to my thoughts. It ’s just that the ETO people did n’t expect that this incident would be counterattacked by you. Instead of solving the idea that the face wall plan may be questioned by the public, it put the development of ETO in trouble. I am today Come here, one is to express gratitude to you, the other question, I want to ask is, if my plan was cracked by ETO, but ETO is not announced, but only inform the three-body civilization, let them in the last battle When you are ready, do such plans make sense? "

Pang Xuelin smiled slightly: "Mr. Rediyaz, I once said that the plan is not static. Our face-to-face plan can be appropriately modified at any time according to the latest technological development of human beings. As for whether it can work, it is not something we have to consider. We only need to fulfill the duties of a face-off, and leave the rest to our descendants to solve it. We must learn to trust them. ! "

Rediaz thoughtfully: "Professor Pang, I see."

Next, Pang Xuelin and Rediaz relaxed and exchanged some views on the current international political and economic situation.

That night, Pang Xuelin and Rediaz ate a meal together.

Early the next morning, Rediyaz went to the hibernation center and was ready to hibernate.

Two days later ~ lightnovelpub.net ~ Pang Xuelin and Vader took a special plane to the Star Circle City for inspection.

A month later, Vader agreed to take over Starring's request.

In the same month, Pang Xuelin established a graphene lithium air battery research and development team.

Six months later, in February of the crisis era, Pang Xuelin returned to China with Cheng Xin and held in-depth talks with senior Chinese officials.

In March, China announced that it would provide further support for the construction of the second phase of the Star Circle City.

At the same time, Pang Xuelin went to look at Zhuang's mother and the Li Yao couple.

Zhuang's mother has remarried, and her life is OK.

Pang Xuelin asked her if she would like to work and work in Xinghuan City. After a long time of consideration, Zhuang's mother chose to refuse.

In April of the same year, Pang Xuelin and Cheng Xin returned to Xinghuan City. Pang Xuelin left Wade with an outline of the technological development of the Xinghuan Institute for the next thirty years, and then went into hibernation with Cheng Xin.
