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

    Shen Wei has a good family background and has learned piano and dance since she was a child.

    This time she will also represent the freshmen performance party and will play the piano.

    ? It was originally a solo performance, but the art department teacher who rehearsed the party said that the solo performance was rather monotonous, so it was changed to a duet performance and a backup dancer.

    Partnering with Shen Wei is Bai Chen, a sophomore from the Art Department, the same boy in a white shirt who gave Shen Wei a McDonald's.

    Perhaps Yenching University has a tradition of romance and literature and art, but Bai Chen is immediately attracted to Shen Wei, a southern girl with a pure temperament and a pleasant appearance.

    When rehearsing the party with Shen Wei, she took care of Shen Wei very much, and of course showed courtesy.

    A boy from the art department and a senior in a senior year, there are many ways to chase girls and there is no shortage of romance.

    Explain playing skills to Shen Wei, buy drinks or food similar to McDonald's for Shen Wei, and give a notebook and other small gifts from time to time.

    No matter how stupid Shen Wei is, she still knows what Bai Chen is thinking.

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

    It was true that she was very hungry during the rehearsal, but Shen Wei didn't 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 apologized and said: "I'm really not hungry, senior, you can eat."

    At this time, the fat man who was rehearsing the chorus, also freshman Yang Xin, was not polite at all. He grabbed the hamburger and said, "Hamburger! I like 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 remembered that when she went to the Internet cafe with Chen Xiao to surf the Internet, she saw the precautions for college freshmen on the bbs - senior brother, fire prevention, theft prevention and prevention.

    Thinking of this, Shen Wei bared a smile.

    Bai Chen was taken aback by this smile, what a clean and contagious smile it was.

    Gao Miao handed the tool to Chen Xiao, and jokingly asked, "Did your girlfriend call just now?"

    Chen Xiao took the tool and started to work seriously, "High school classmate."

    Gao Miao asked again: "Girls"

    Sure enough, women have the potential to gossip.

    Chen Xiao didn't hide anything and said, "A female classmate with a good relationship."

    Gao Miao chuckled, "Where do you study?"

    "Yanjing University, Sister Miao Miao, you are a bit gossip!"

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

    Gao Miao seemed to think of something that she could recall endlessly.

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

    You understand it!

    Still Xiaoxiao?

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

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

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

    Because the best negative electrode material for ternary lithium batteries is graphene, not rough carbon powder.

    Ternary lithium batteries are best to use nano-scale polymers. Diaphragms, so that ions can pass through smoothly while other substances in the solution do not pass through, increasing 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-diaphragm, only fiber membrane and carbon powder, so this is a simple version of the ternary lithium battery.

    In addition, Chen Xiao also packaged a traditional lithium cobalt oxide battery.

    Because the packaging technology is much better than Gao Miao's own thinking, the performance and stability of the battery are also very high.

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

    She and the team members have been tinkering with something that didn't work for more than half a year, and now it's done?

    After you finish, you can write a thesis. Not only can you write a thesis, but you can also submit it on time.

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

    Chen Xiao installed an aluminum film on the outside of the two lithium batteries, and then put a label on them, ready to test them later.

    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 aluminum foil, an adhesive, and an inner heat-sealing layer, there is no such condition in the laboratory.? After tinkering, aluminum film was used.

    The aluminum film can also improve the explosion resistance of the battery.

    "Eat first and then experiment?"

    Chen Xiao was not too polite, and ate a box lunch with Gao Miao, and ate the whole chicken leg by the way.

    In the quiet laboratory, only the sound of two people eating.

    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 together for the postgraduate entrance examination and I could get into a better university. If we can meet you in the first year of research, we will be there  In the second year of research, we can do scientific research and make papers together, and we don¡¯t have to rush to catch up with the progress now.¡±

    Chen Xiao gnawed on the chicken leg and said, "Sister Miao Miao, don't dream, I was just in the first year of junior high when you were freshman."

    Listening to Chen Xiao's serious calculation of the time account, Gao Miao couldn't help but grin.

    After the meal, the two of them were unwilling to procrastinate any longer.

    Start a series of tests on the battery.

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

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

    Among them, the capacity of lithium cobalt oxide battery with 18650 battery specification can reach 2000mah, the voltage can be stabilized at about 3.6v, and the energy density can reach 150mahg.

    The energy density of the ternary lithium battery has reached 210mahg, and the capacity can reach 2700mah.

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

    Ordinary enterprises can produce qualified industry products, while excellent enterprises formulate industry standards.

    Obviously, the current standard is set by Sony.

    The performance of lithium cobalt oxide batteries is already comparable to that of Sony's standardized lithium batteries.

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

    Although the ternary lithium battery is not the first invention of Chen Xiao (the use of three kinds of lithium-containing compounds as the positive electrode is the ternary lithium battery), Chen Xiao is definitely the first time to sort out and make a mass-produced and very stable battery.  ternary lithium battery.

    When Chen Xiao reported the last data and Gao Miao wrote the data, the laboratory fell silent.

    It worked!

    It worked!

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

    "ah!!"

    Gao Miao yelled excitedly, ran over to hug Chen Xiao, and shouted loudly: "Xiaoxiao! We succeeded! Woohoo! We succeeded!"

    Because of excitement, Gao Miao and Chen Ling stuck together.

    Um!

    Great feeling.

    Chen Xiao coughed twice and said, "Senior sister, we can prepare the thesis now."
