When I was five years old, I helped my mother do test papers live, and I became popular

The recent cat, Xiao Mi, no longer sleeps on the sweeping robot, but lies on the balcony to bask in the sun.

It's not because it's better to supplement calcium after basking in the sun.

It's because the sweeping robot is broken.

Lin Shiqing saw that the robot vacuum could not suck dust and could only move, so she took it apart for repair.

After her repairs, the sweeping robot was completely broken and couldn't even move.

Cat Xiaomi naturally won't lie on things that can't be moved.

How nice to bask in the sun.

As soon as Ye Xiaotian returned to the dormitory, he saw the lazy cat basking in the sun, so he hugged it and put it on the table.

"Meow meow!"

The cat Xiaomi meowed a few times.

Still pretending to be stupid.

Ye Xiaotian smiled, clenched his right hand and stretched out, as if something mysterious was held in the fist.

Cats are extremely curious.

So Maoxiaomi brought the fat head closer, wanting to see what's inside.

Ye Xiaotian slowly raised his middle finger.

The internationally accepted gesture can not only humiliate people, but also provoke animals.

Mao Xiaomi grinned, obviously angry.

boom!
Ye Xiaotian slapped the cat's head with a slap, and then said with a smile on his face:

"Bad cat, let me show you something."

The cat who was shot on the head became even more angry.

His eyes were fixed on Ye Xiaotian.

He should be thinking about whether to bite him or not.

Bite him and he may be eaten.

But if you don't bite, you really can't relieve your anger.

Ye Xiaotian turned on the computer, and typed in the search engine:
How to make orange cat delicious.

Click Search.

Find a lot of solutions, as well as video explanations.

Ye Xiaotian put Mao Xiaomi in front of the computer, held the cat's head with his left hand so that he could see the screen, and then clicked on a video.

A young lady appeared in the video.

The young lady is holding a kitchen knife in her left hand and a cat made of dough in her right hand, and she is talking eloquently:
"How can the orange cat be delicious?"

"First boil the water, put the orange cat in the scald for half an hour, and then start to pluck the hair."

"Cut the orange cat into pieces, set up an oil pan, and put in the orange cat meat."

"Put chili peppers and stir-fry over high heat."

Mao Xiaomi may not understand what the young lady said.

But it definitely understands the actions in the video.

Kitten: Σ()

During the whole playing process, Mao Xiaomi's expression is the same as above.

Even after the playback ended, the expression remained unchanged.

Ye Xiaotian hugged the cat Xiaomi, then looked into its eyes, and asked with a smile:
"Do you still dare to ruin other people's takeaway?"

It turned out that Ye Xiaotian didn't want to scare it like this.

But this fat orange is too much.

It’s okay for you to steal one or two takeaways. The worst thing is that you don’t like the food and kick it down with jio.

Everyone is working hard.

Cats who waste food should be taught a lesson.

"Meow!"

Mao Xiaomi let out a cry, put on a cute look, and started acting cute, and kept rubbing Ye Xiaotian's hand with her fat face.

It is impossible to be angry, it is impossible in this life, and now I can only maintain my life by being cute.

Ye Xiaotian asked: "Are you aware of your mistake?"

"Meow!"

The cat yelled immediately.

Ye Xiaotian smiled and said: "I know I was wrong, I will lock you up for a while."

When the cat Xiaomi was put in the cage, its cute appearance disappeared, and it turned into a fierce grinning appearance.

Ye Xiaotian pointed to the computer screen and threatened: "Be safe, or I'll fire you later."

"Meow!"

The cat Xiaomi has become cute again.

Lin Shiqing came out and asked curiously: "Xiao Tian, ​​why did you lock Xiao Mi?"

"Meow!"

Mao Xiaomi quickly barked, wanting Lin Shiqing to let it go.

Ye Xiaotian glanced at it, smiled selectively, and then told his mother about Mao Xiaomi stealing food.

After listening, Lin Shiqing became angry.

Fortunately, she was worried before that if the fat orange didn't eat, he might be sick.

Those who dare to love have already eaten and drank outside.

How can you still value the cat food at home when you eat big fish and meat outside?

Lin Shiqing angrily leaned in front of the cage, pointed at Mao Xiaomi, and cursed:

"You scumbag, the food outside is better than the food at home?"

Ye Xiaotian was speechless.

Mom's focus seems to be biased.

Ye Xiaotian reminded: "Mom, it's not a question of whether it tastes good or not. The point is that this fat cat not only steals other people's takeaway, but also wastes food."

Lin Shiqing said: "Wasting food is a shameful act."

Ye Xiaotian glanced at Maoxiaomi, and suggested: "Mom, why don't we kill it, I heard that stir-fried cat slices are very delicious."

Cat Xiaomi:!

Lin Shiqing smacked her lips and said, "You can have this."

Cat Xiaomi:! ! !

"Meow!"

Mao Xiaomi quickly became cute, her fat body rolled around on the ground.

In order to save its life, it put on a cat face.

After half an hour.

Kitten is still alive.

Ye Xiaotian said directly: "It's shameful to be cute."

Then ignore it and go take a nap.

After taking a nap, Ye Xiaotian went to the laboratory.

Jiang Yuting is still in the laboratory, observing the chemical reaction of lithium-sulfur batteries.

This tool man, ahem, hardworking senior sister is so cute.

Ye Xiaotian came over and asked, "Senior Sister, didn't you take a nap?"

Jiang Yuting shook her head.

Ye Xiaotian pointed to the corner and said, "Go to the table over there and squint!"

Jiang Yuting shook her head and said, "No need, I'm not tired, just watch your junior brother do the experiment."

Ye Xiaotian asked suspiciously: "Can you understand?"

Jiang Yuting shook her head, feeling that she was hurt by a hundred critical strikes.

right!

I couldn't understand it so badly, I watched it all afternoon.

What a fool.

Ye Xiaotian said: "You'd better go over there and rest for a while, I'll call you again if something happens."

Jiang Yuting warned: "Junior brother, you have to be careful."

Then he walked to the corner depressedly.

Ye Xiaotian came to the side of the experiment and carefully looked at the battery model inside the device.

The lithium in the negative electrode is almost gone.

The reaction essentially stopped.

Ye Xiaotian muttered to himself: "The problem of the shuttle effect."

After the sulfur at the positive electrode obtains electrons, it will generate a polysulfide compound. The polysulfide passes through the separator to the negative electrode, and chemically reacts with lithium to consume lithium.

So the negative pole is almost gone.

This shuttle effect greatly affects the life of the battery.

If it can't be solved, then the manufactured lithium-sulfur battery is meaningless.

There are mainly two solutions.

The first is to start with the electrolyte.

The second is to start with the cathode material.

Ye Xiaotian took out two blank sheets of paper, and drew a simple diagram of a general battery reaction on one of them.

On the other one, a simple diagram of the reaction of the lithium-sulfur battery given by the system is drawn.

After carefully comparing the two pictures, Ye Xiaotian smiled faintly and said in a low voice:
"It's good to have a system."
