Chapter 562: Song Yao likes to play with contrast

The black business car drove smoothly on the asphalt road. Inside the car, the topic transitioned to energy security.

"Energy is a strategic stronghold of the country. We also discussed at the meeting last month, preparing to increase R&D investment in this area."

Du Changdao sighed and said.

Xu Qingzhou nodded in agreement. Europe and America are gradually raising technical thresholds, slowing down the development of Xia Nation's technology through technical blockades and supply chain restrictions.

In the next few years, the international environment will be more complex.

"Currently, the international environment is increasingly complex. The United States treats us as a major competitor, attempting to contain our development in major fields, causing constant trade friction, and even intensifying. The energy field is the focus of competition in the future."

Wang Tong said, his deep gaze looking at Xu Qingzhou, and asked curiously: "What do you think is the direction of future energy development?"

"Lithium-sulfur batteries and controllable nuclear fusion."

Xu Qingzhou answered without thinking. Although controllable nuclear fusion is still stuck on PPT and cannot be commercialized, it is definitely the most promising clean energy.

Wang Tong thought for a while and pondered: "Lithium-sulfur batteries... but the hot one currently seems to be solid-state batteries."

"That's right, solid-state electrolytes are non-flammable, completely solving the risk of thermal runaway in traditional lithium batteries, and the theoretical energy density has reached 500-900 Wh/kg, which can basically support electric vehicles for a range of over 1,000 kilometers."

Xu Qingzhou continued with a smile: "And the theoretical energy density of lithium-sulfur batteries can reach 2600 Wh/kg, which is several times that of solid-state batteries. Of course, this requires us to make breakthroughs in materials science, which is also one of the meanings of the Kyoto Institute of Materials."

Now the mainstream voice leans towards solid-state batteries, which, by virtue of their safety and energy density advantages, can certainly become the mainstream of power batteries before 2030.

However, with Xu Qingzhou, this cheater, things are a bit different.

Maybe... it can make the lithium-sulfur battery era arrive early.

Du Changdao fell into deep thought. He has always been in the field of education and was also engaged in technology before entering politics. He understands the predicament of lithium-sulfur batteries better than Wang Tong. Wanting to develop lithium-sulfur batteries is very difficult.

Whether it is lithium dendrites or the shuttle effect, they are all big mountains.

But...

Things always develop in twists and turns. Perhaps, this young man in front of him can bring surprises to Xia Nation?

Xu Qingzhou smiled, paused, and said: "As for nuclear fusion, it is considered the 'high ground' of future energy and is the next goal of the institute."

"Professor Xu is also involved in nuclear fusion?" Wang Tong was puzzled.

"Involved."

Although Xu Qingzhou specializes in quantum mechanics, he was quite interested in particle physics and nuclear fusion physics before, and had exchanges with many top scientists at that time.

"I have witnessed the development of Xia Nation over the past few decades. It can be said that every day is changing with each passing day... This is inseparable from the contributions of scientists like you who are fighting on the front line."

"You are over-praising..."

After chatting about technology simply, the topic became relaxed. Wang Tong appropriately led to the life of the two in Boston, saying that he had stayed abroad for a few years and was very unaccustomed to it.

The group had a simple meal at the arranged hotel. Because they knew that Xu Qingzhou and Song Yao had taken a flight for more than ten hours, there were not many complicated ceremonies.

The two said goodbye to Wang Tong, Du Changdao, and others at the hotel entrance, took the business car just now, and at 11:30 AM, finally returned to their long-lost little nest.

Pushing the door in, the room carried a faint damp smell of not having been lived in for a long time.

"Finally home."

Xu Qingzhou sat on the suitcase, exhausted.

Song Yao moved a slightly lighter one, and he handled the other three large suitcases alone. I don't know how School Beauty Song packed the clothes; each suitcase was like a lead ball stuffed inside.

Unlike Xu Qingzhou, Song Yao was still beautiful, still a cold and pretty little fairy. Looking at the sweating Xu Qingzhou, she despised: "Weakling."

"Heh, you try carrying these three suitcases back and forth."

Xu Qingzhou retorted.

Song Yao curled her lips and didn't speak, letting out Er Miao who had been locked in the box for more than ten hours.

Seeing the familiar environment, the tabby cat's eyes regained some spirit, wagging its tail and patrolling the territory in the room.

Song Yao clapped her hands, took a broom and a rag, and went into the bedroom to clean up.

The two spent an afternoon cleaning the house inside and out.

5:00 PM, the sun shot from the southwest, penetrated the glass, and fell on the corner of the sofa. Er Miao lay lazily in the sun.

Due to the time difference, both of them were a bit drowsy.

Xu Qingzhou played with School Beauty Song's hair with his hands, looked at the living room, and the four suitcases were stuffed into the second bedroom, so it was no longer crowded. He thought of more important things and said: "Should we find a time to settle the house first?"

Yandongyuan is certainly more comfortable than staying in a hotel, but this is not his own after all. This may be the house complex of Xia Nation people, especially after marriage, there must be a house of one's own.

Song Yao nestled in Xu Qingzhou's arms, lazily saying: "Hmm, let's go see it the day after tomorrow, you don't have anything else, right?"

"No."

Xu Qingzhou shook his head. Tomorrow is Friday, and he made an appointment with Ji Yunshi to see the construction of the institute, and then visit the two former supervisors. Saturday is just empty.

"We will go see the house on the morning of the day after tomorrow, and Jiahui and the others will come over in the afternoon."

Song Yao had already arranged the weekend full, and after finishing, took a deep breath, cheered up and stood up, "Let's go, go out to buy vegetables."

"Order takeout."

Xu Qingzhou felt troublesome and didn't want to move, pulled Song Yao back, traveled for more than ten hours, and it was so comfortable to lie down and recharge.

Song Yao rubbed the face of the boy under her, pinched her throat and said: "Xu Qingzhou~ this is the first meal at home."

That weak voice, even Song Yao herself had a goosebump.

Too artificial.

How did she gradually learn this thing.

However, Xu Qingzhou eats this set very much. When pretending to be a weak little girl, this guy enjoys it very much. By the way, exclude it when doing bad things with this person. The more miserable the call, the harder Xu Qingzhou works, and she is even more miserable...

Too perverted.

Song Yao despised Xu Qingzhou again in her heart.

"I want to sleep." Xu Qingzhou laughed, with a fatigue after staying up all night. Of course, for his current age, his body is in its peak, unlike before, when he came back from a business trip, that feeling of sudden death came wave after wave.

"Xu Qingzhou~" Song Yao called out delicately.

Xu Qingzhou secretly sighed that this girl is good at contrast, acting cute and so on, coming at her fingertips.

"Xu Qingzhou~"

Xu Qingzhou remained unmoved. He must go out. This is the first meal at home after all. He should do it himself, but he inexplicably wanted to listen to a few more sounds.

Song Yao also saw that this guy was secretly enjoying it, so she cooperated and called a few times, just as charging him.

But seeing this person squinting, without the consciousness of getting up, she pulled a small face: "Xu Qingzhou."

This time you can't say she is violent, it is clearly you who are looking for a beating.

Song Yao thought in her heart.

Sure enough, she saw Xu Qingzhou get up nimbly, full of energy.

"Go go go."
