Rebirth 1999: Opening the Age of Black Technology

On September 30, Yenching University will hold a party to welcome the National Day and new students.

Shen Wei came from a good family and studied piano and dance since childhood.

This time, she will also perform a party on behalf of freshmen and will play the piano.

It was originally a solo performance, but the art department teacher at the rehearsal party said that the solo performance was rather monotonous, so it was changed to double performance and backing dance.

The partner with Shen Wei is Bai Chen, a sophomore in the art department, that is, the boy in a white shirt who gave Shen Wei a McDonald's.

Yenching University may have a tradition of romance and literature. Bai Chen was immediately attracted to Shen Wei, a southern girl with a simple temperament and a pleasant appearance.

When rehearsing the party with Shen Wei, she took good care of Shen Wei, and of course she was also diligent.

The boy in the art department is also a senior in the senior year. There are many ways to chase girls, but there is no lack of romance.

Explain the technique of playing to Shen Wei, buy Shen Wei a drink or food similar to McDonald's, and give a notebook and other small gifts from time to time.

No matter how stupid Shen Wei was, she knew what Bai Chen was thinking.

She called Chen Xiao just to talk about the troubles she encountered.

She was really hungry during the rehearsal, but Shen Wei didn't go to pick up Bai Chen's hamburger. She smiled and said, "Thank you, senior, I'm not hungry yet."

Bai Chen put the hamburger in front of Shen Wei and said, "You're welcome, eat it quickly."

Shen Wei said apologetically, "I'm really not hungry, senior, please eat."

At this time, the fat man who was rehearsing the chorus, Yang Xin, who was also a freshman, was not polite at all. He grabbed the hamburger and said, "Hamburger! I like to eat it the most! Thank you, Senior Bai."

Yang Xin opened the outer layer of paper and ate the hamburger in two bites, leaving Bai Chen with a messy face.

Shen Wei suddenly thought that when she went to the Internet cafe with Chen Xiao to surf the Internet, she saw the precautions for college freshmen at BBS—Senior Brother Fire, Burglary and Prevention.

Thinking of this, Shen Wei burst into a smile.

This smile made Bai Chen crazy, what a clean and infectious smile.

Gao Miao handed over the tools in his hand to Chen Xiao, and asked jokingly, "Is it just a call from my girlfriend?"

Chen Xiao took the tool and started to work seriously, "Classmate from high school."

Gao Miao asked again: "Girls"

Sure enough, women have the potential to gossip.

Chen Xiao didn't hide it and said, "A female classmate who has a good relationship."

Gao Miao laughed, "Where do you study?"

"Yenjing University, Sister Miao Miao, you are a bit gossipy!"

Gao Miao patted Chen Xiao on the shoulder, "One south and one north, Xiaoxiao, it's not my sister who is gossiping, it's this feeling, I understand! Hey!"

Gao Miao seemed to have thought of something that made her endlessly reminisce.

Chen Xiao stared at Gao Miao and couldn't help but want to complain.

you got it!

Still Xiaoxiao?

At eight o'clock in the evening, Chen Xiao spent a whole day to complete the packaging of the simple version of the ternary lithium battery.

The weather in the laboratory was not too hot, but Chen Xiao was already sweating profusely.

Why is it a simple version of the ternary lithium battery?

Because the best anode material for ternary lithium batteries is graphene, rather than rough carbon powder.

It is best for ternary lithium batteries to use nano-scale polymers. Separator, so that ions can pass through smoothly and other substances in the solution do not pass through, improving the energy density of the battery.

However, due to the limitations of technology and materials of the times.

There is no graphene, no polymer nano-separator, only fiber membrane and carbon powder, so this is a simple version of the ternary lithium battery.

In addition, Chen Xiao also encapsulated traditional lithium cobalt oxide batteries.

Because the packaging technology is much better than what Gao Miao thought about, the performance and stability of the battery are also very high.

"It's done?" Gao Miao's eyes were shining!

She and the group members have been fiddling with something that has no effect for more than half a year, and now it has become?

Once you are successful, you can write a dissertation, not only can you write a dissertation, but you can also submit it on time.

When Chen Xiao was making packaging just now, Gao Miao was worried that Chen Xiao was hungry, so he went to the cafeteria to buy Chen Xiao rice and a piece of braised chicken thigh.

Chen Xiao put aluminum film on the outside of the two lithium batteries, and then put a label on it, ready to test for a while.

Why not use aluminum plastic film?

Because the aluminum-plastic film is a multi-layer film composed of an outer nylon layer, an adhesive, an intermediate layer of aluminum foil, an adhesive, and an inner heat-sealing layer, the laboratory does not have this condition, so the aluminum film is used.

The aluminum film can also improve the battery's explosion resistance.

"Eat first and then experiment?"

Chen Xiao was not polite, and had lunch with Gao Miao, and by the way, he ate the whole chicken leg.

There was only the sound of two people eating in the quiet laboratory.

Gao Miao couldn't help sighing and said, "Why didn't I meet you earlier? If you were my classmate in the first year of freshman year, maybe we could review the entrance exam together, and I could get into a better university. If I can meet you in the first year, we will be there. In the second year of research, you can do scientific research and get papers together, and you will not be in a hurry to catch up with the progress now.”

Chen Xiao nibbled at the chicken leg and said, "Sister Miao Miao, stop dreaming. I was just in the first year of junior high when you were a freshman."

Gao Miao couldn't help but burst into a smile after listening to Chen Xiao's serious calculation of the time.

After the meal, the two of them didn't want to drag their time.

Start doing a series of tests on the battery.

Including battery energy density, battery capacity, battery anti-knock performance and so on.

At eleven o'clock in the evening, all the data came out.

Among them, the capacity of the battery-sized lithium cobalt oxide battery can reach ~www.readwn.com~ The voltage can be stabilized at about 3.6V, and the energy density can reach 150mAhg.

The energy density of the ternary lithium battery reaches 210mAhg, and the capacity can reach 2700mAh.

The anti-knock performance is also very good, reaching the line standard specified by Sony for lithium batteries.

Ordinary companies can produce qualified industry products, while excellent companies set industry standards.

Obviously, the current standard is set by Sony.

The performance of the lithium cobalt oxide battery is comparable to that of the standard lithium battery produced by Sony.

If Chen Xiao has a standardized production workshop, the performance of lithium cobalt oxide batteries will be even stronger.

Although the ternary lithium battery is not the first invented by Chen Xiao (using three lithium-containing compounds as the positive electrode is the ternary lithium battery), but Chen Xiao is definitely the first time to sort out and make it that can be mass-produced and is very stable ternary lithium battery.

When Chen Xiao reported the last data and Gao Miao wrote down the data, the laboratory was quiet.

It worked!

It worked!

Success came so suddenly, yet so clean and logical and organized!

"what!!"

Gao Miao screamed with excitement, ran over to hug Chen Xiao, and shouted: "Xiao Xiao! We succeeded! Woohoo! It's successful"

Gao Miao stuck with Chen Xiao because of his excitement.

Um!

Great feeling.

Chen Xiaoxiao coughed twice and said, "Senior sister, we can prepare the paper."
