Chapter 575: Is it a crime to be a single dog?

July 26th.

After playing outside for more than half a month, Song Yao also missed the lazy cat at home. After returning home, she went to the cattery to pick up Er Miao, who was fostered, first.

Having an extra cat at home suddenly made it lively.

The two leaned on the chairs to rest, outside the window was the beautiful lake view,

After more than half a month, returning from the desolate Northwest land to the prosperous modern metropolis, they both felt dazed, but looking at the familiar residential area and house, they felt inexplicably stable.

Facts proved that Song Yao was overthinking, worrying that Er Miao would be depressed if she didn't see them for too long.

This guy seemed to have had a very comfortable life in the cattery, staring with two round eyes, running around in the living room, seeming even more energetic than the two of them who had just come back from shopping outside.

It hadn't been lived in for too long, and the house always had a moist atmosphere after being idle. After the two rested simply, they started cleaning and opened the windows to ventilate.

Two days passed.

A night rain washed the Kyoto sky.

Outside the window, the trees were moist, and the air carried a cool earthy scent.

Today is Monday, Song Yao went to shop and watch a movie with Zhang Qiong, who had just returned with her tutor, while he himself made a cup of coffee and entered the study leisurely.

The books Song Yao bought had arrived long ago. Although the originally empty bookshelf wasn't filled, it was much better than when they first moved in, full of book fragrance.

Besides books on economics, law, and mathematics, there was also a pile of novels.

"The Three-Body Problem," "A Madman's Diary"... "The Red and the Black," "The Old Man and the Sea," "Anna Karenina"...

He pulled out "The Old Man and the Sea," opened a page casually and read it. He had read it several times before, so he didn't have to struggle with where to start.

Compared to professional books, he actually rarely reads novels now. Maybe after becoming an adult, his utilitarianism is stronger, and he always wants to get something when reading books.

Occasionally flipping through books, there will be a sense of tranquility.

After reading for half an hour, Xu Qingzhou exhaled, opened the computer, relaxed enough, and it was time to do business.

The task is urgent.

Nowadays, the competition in the new energy field is in a white-hot stage, the Xia-Russia-Africa Resource Alliance vs. the US-Europe-Japan-South Korea Technology Alliance, forming a supply chain partition.

According to the development of the previous life, the Xia Nation will have an absolute advantage in this field in the next few years, for example, lithium iron phosphate (LFP) batteries cost 20% lower than Japanese and Korean nickel-based batteries.

And Europe and the US are trying to reconstruct the order through policy barriers and technological blockades.

Finally, in the era of lithium-sulfur batteries and nuclear fusion energy, the international landscape has changed again. Although the Xia Nation has not fallen behind, it can no longer dominate.

If he succeeds...

Maybe it can keep the country in a leading position.

International competition is so cruel, technological blockades, policy boycotts, etc., are all routine means, and the Xia Nation has been arranged by Europe and the US for decades like this.

For the institute's experiments, he plans to divide them into two directions, namely lithium dendrites and the shuttle effect, and promote them in groups simultaneously.

He had done some lithium dendrite experiments at MIT, and even had some data, because he understood all the current situations of lithium dendrites.

The more troublesome one is the shuttle effect, which can be said to belong to a field he is relatively unfamiliar with and needs to start from scratch.

Xu Qingzhou typed quickly, found relevant information on the shuttle effect, and he was used to looking at definitions first, then sorting out the experimental outline.

Before studying something, you have to figure out what it is first.

The shuttle effect is a capacity decay phenomenon in lithium-sulfur batteries caused by the migration of soluble polysulfides of intermediate products between the positive and negative electrodes.

Currently, the shuttle effect has three specific manifestations.

1. Positive electrode dissolution: Sulfur (S) generates polysulfides during discharge, which dissolve in the electrolyte.

2. Migration to the negative electrode: Crossing the diaphragm under the drive of concentration gradient, reacting with lithium metal to generate LiS/LiS.

3. Irreversible loss: Some polysulfides cannot return to the positive electrode, leading to loss of active substances, reduced coulombic efficiency, and corrosion of the lithium negative electrode.

Direct hazards, battery cycle life is rapidly shortened and overcharge risk, at the same time, it is related to lithium dendrites, which will accelerate lithium dendrites, thereby causing safety hazards.

The shuttle effect is one of the core problems restricting the commercialization of lithium-sulfur batteries. Currently, mainstream solutions are basically combining physical confinement, chemical anchoring, and catalytic conversion synergy, that is, positive electrode material modification, diaphragm improvement, or strong adsorption of polysulfides through chemical bonds (S-O, Li-N), etc.

Unfortunately, there is still no means in the world to completely solve the shuttle effect.

Currently, the institute has sent interview notices to 100 scholars who submitted resumes, and the interviews will officially start on August 1st, preparing to determine the personnel list before the 10th.

Most of the equipment has arrived in Kyoto and entered the installation stage.

At 6:30 PM, orange light shone from the southwest.

On the side of the road, Xu Qingzhou held his phone, followed the navigation prompts, and finally found the iron pot stewed goose sent by Song Yao.

He originally planned to cook some noodles to deal with it, but Song Yao called and asked him to come out to eat. This girl probably saw him staying at home for a few days again and wanted him to come out for a walk.

As soon as he entered the shop, he saw two girls in the corner waving at him.

"There are so many people even on Monday." Sitting next to Song Yao, looking at the crowded shop, Xu Qingzhou smacked his lips.

"The taste here is very good, it's full every day, I made an appointment on Friday."

Zhang Qiong smiled.

While speaking, she was also looking at Xu Qingzhou. They hadn't seen each other for almost two years, he was a bit tanned, and his appearance was more mature.

Song Yao handed over a drink and said: "We bought you milk tea."

"New product? I suspect you are taking me to step on a pit..."

Xu Qingzhou narrowed his eyes.

"I also bought a new product." Song Yao shook the cup in her hand.

Xu Qingzhou inserted the tube, took a sip, and commented: "The taste is not bad."

Seeing Song Yao looking at himself, eager to try, he handed the milk tea over, and saw Song Yao take a big sip, "Better than mine."

"Heh, I won't change with you."

"As if anyone wants to."

"You two, I'm still here."

Zhang Qiong looked at the two flirting people and reminded them faintly opposite.

Is it a crime to be a single dog?

She had long been used to the changes in Song Yao's persona. Coldness or something, completely non-existent. When shopping, she was thinking about buying something for Xu Qingzhou.

"Husband slave."

A word suddenly popped into Zhang Qiong's mind.

Song Yao is not cold, but only has Xu Qingzhou in her eyes.

Will Xiaoyao suffer a loss?

Zhang Qiong shook her head in her heart, a bit funny, secretly saying she was worrying blindly, these two were already married, quite happy.

Besides, if she had such an excellent partner, she would probably stick to the other party too.

Xu Qingzhou, indeed quite good.

On this side, Xu Qingzhou handed his milk tea to Song Yao, picked up Song Yao's original cup and took a sip, and also noticed the resentment of the girl opposite, so he put the milk tea down and asked with a smile: "Your boyfriend didn't come?"

Zhang Qiong: "?"
