"Hello everyone, I'm Wang Fan."

"This time, I would like to make a report to you, and the theme of the conference is - the performance of silicon carbon anode material ion batteries and the future prospects of the industry."

Wang Fan held the microphone, coughed lightly twice, and then looked at the crowd under the stage, he couldn't help but feel a little surging in his heart.

This world-class academic report.

Even if it was in the previous life, he struggled in the industry for decades.

It is also a point that has never been reached.

However, in this life, less than a year after coming, it was easily reached.

For a short time, he thought about it a lot, then put aside all distractions, recalled all the relevant process processes in his mind, and said slowly:

"I believe everyone knows that the silicon carbon anode material ion battery is based on today's silicon-based system."

"In the traditional sense, silicon-based cells have a huge volume effect in the charging and discharging process, and can achieve a 300% volume change in the silicon de-intercalation process, which can easily lead to particle differentiation and thus fall off the current collector."

"At the same time, electrode polarization, material differentiation, SEI mode reconfiguration, low coulombic efficiency and continuous capacity depletion are also important problems faced by silicon-based cells."

Wang Fan first threw out the current problems in the new energy industry, and extended it to the back little by little, which further attracted everyone's attention.

After all, scholars and experts came here to find out how Wang Fan solved the problem, so as to give themselves some inspiration.

Originally, he had a draft, but when it came to the back, he simply took off the draft, and ideas began to rush out little by little like wild horses.

"However, the advantages of silicon carbon anode materials are well combined to form an energy storage device with stable structure, good circularity and high capacity."

"By adjusting the proportion and size of the material mixture, such as high-precision nanologization, we can greatly alleviate the huge stress caused by the volume change of silicon, and at the same time, nano-silicon can shorten the transmission distance of LI+, which is conducive to improving the kinetic properties of the material."

"At the same time, because of the large specific surface area of silicon nanoparticles, SEI films are prone to excessive consumption of lithium salts, and the volume effect is easy to cause electrical detachment between particles, resulting in a decrease in reversible capacity and storage efficiency."

"On this basis, the addition of carbon composites can not only enhance the conductivity of the system, but also stabilize its interfacial properties, thereby improving the cycling stability and the ............ of charging and discharging life."

Wang Fan opened his first direction.

The scholars and experts in the audience listened fascinated.

At the same time, in order to further alleviate the volume expansion of silicon. To generate a stable SEI film, the silicon carbon anode ionic material adopts a new core-shell structure, which provides some volume for the volume expansion of silicon and reserves space to ensure that the surface carbon layer structure is not destroyed, and a stable SEI film is obtained..............."

"I, Nima, brothers, what is your situation, can you still understand?"

"Do you understand? Big brother upstairs, what are you talking nonsense, if I can understand, I'm standing on the stage now, with my hands on my hips. ”

"As an industry practitioner with a bachelor's, master's and doctor's degree in 985, I want to say that I can keep up at first, and it sounds quite energetic, but the more I go to the back, the more confused I listen, and when I am about 20 minutes, I already feel that I am listening to the book of heaven."

"You can understand every word when you break it open, and you don't know what you're talking about when you put it together."

………

At this time, with the official start of Wang Fan's academic report.

The traffic on the live streaming platform has finally stabilized.

It reached 800,000 people.

It's not more than a million, but it's very, very explosive.

You know, this is just an academic conference, not a live broadcast with goods, which has very strong professional restrictions and thresholds, and for the general public, they may not be able to accept the so-called academic conference exchanges for a lifetime.

Five o'clock in the afternoon.

In a round of applause.

Wang Fan concluded this academic report.

"Old Wu, after listening to the report."

"I seem to understand a little bit, it's like the Heavenly Spirit Cover has been opened a little, and I understand something in an instant."

Chen Wei, who was sitting in the audience, suddenly came with this sentence out of nowhere:

"It's no wonder that the boss gives us the opportunity to participate in more academic presentations like this."

"It's really good."

“………… The heavenly spirit cover opened a little, you kid really knows how to describe it. ”

Wu Zhilin, who was on the side, said angrily, and then added: "In the past three hours, as long as there is something in the stomach, there will be some insights, after all, they are all research in the same industry, and a considerable part of the experience can be used for reference." ”

"It's the same with our next hydrogen-oxygen combustion battery."

"Now I suddenly feel that the group of silicon carbon anode material ion batteries is a bit good, the starting point is much higher than ours, not to mention anything else, at least we can directly put into the work, and we can enter the future technology group of the boss and dock with all aspects."

Chen Wei touched his chin, looked at the other group around him, and opened his mouth with some envy.

As he spoke, Wu Zhilin glanced at Chen Wei: "Why don't you apply for a transfer now?" ”

Although Chen Wei said so, both he and Wu Zhilin knew that the future energy development direction of the laboratory was hydrogen and oxygen combustion batteries, and as long as they could survive the early stage, there would be a Zhuangkang Avenue behind.

Compared with sweet first and then bitter, Chen Wei still chose bitter first and then sweet.

"How can this be, Lao Wu, you underestimate me too much, I'm just talking casually, you don't know, I'm a little good when I'm young, no matter what, as long as I choose something at the beginning, I won't change."

While the two were arguing, Wang Fan on the stage was surrounded by a swarm of enthusiastic students as soon as he stepped down.

"Senior Wang Fan, I want to take a photo with you."

"Big Brother Wang Fan, I want an autograph."

"Professor Wang Fan, I want to ......"

……………

That's it.

Wang Fan signed the word for two hours with tears, and his hands were about to cramp in the back, plus being a tool man for an hour.

No way.

The promise made at noon now has to be swallowed in the stomach even if you break your teeth.

"Good fellows."

"It's really not human."

Wang Fan shook his already sore arm and walked out of the playground leisurely.

Although the report of this meeting has ended, scholars can still be seen everywhere in the playground, holding computers or pen and paper, discussing fiercely with each other, and arguing from time to time.

"That's great!"

"That's the beauty of academic exchange."

Wang Fan sighed to himself.

"Ding-dong ........."

Just as he was thinking about it, Wang Fan suddenly heard a mechanical sound in his ears.

"Congratulations to the host, the points have reached the first-level limit."

"Do you want to upgrade?"

In the next second, Wang Fan's personal attribute panel appeared directly in front of him.
