Rebirth of the New Farmers in the 1980s

Luan Feng had already run out to meet the triumphant warrior, but what he said was very unpleasant to listen to.

"Zhang Xuan! If you come back two days later, you won't be able to see me."

Zhang Xuan had a question mark on his face: "Are you going to die?"

"You're finished. Wan Feng and I are going to play in the south, so of course you won't be able to see me."

Listen, what you said, others thought you were going to drive west.

"I'm going to the south too."

"Didn't you agree to help me take care of the factory with Jiang Min at home? Why did you change your mind again? Are you sure?"

Wan Feng didn't find it strange that Zhang Xuan wanted to follow her to the south. If she didn't ask to go, it would be a ghost.

But asking to go and being able to go are two different things.

Just in case, Wan Feng also applied for her when applying for the border defense certificate this time, of course using someone else's name.

Her registered permanent residence is in Longjiang, and Wan Feng is not capable of going back and forth to Longjiang within two or three days to apply for a border defense certificate for her.

In the late 1980s, it was not too difficult to obtain a certificate. Even if it was impossible to obtain a false certificate, Wan Feng was confident to get in.

It's not too difficult to just put a stamp on the photo.

"Just let Jiang Min and Erman watch the factory. I'm afraid you'll get lost outside because you're so confused."

"What are you talking about, you mean I'm that dead man?" Luan Feng rolled her eyes dissatisfied.

Zhang Xuan smiled slyly: "You said it yourself."

Luan Feng showed her family's unique Nine Yin White Bone Claw on the spot, chasing Zhang Xuan all over the yard.

Wan Feng didn't have time to watch his two women running in the yard, because it was useless to watch, and he didn't dare to straighten his back when he saw the reaction. It would be better not to watch if he was ashamed.

So, when the two women were chasing after each other, Wan Feng went back to the factory to see what Yang Li and his classmates were doing now.

When Wan Feng came to Yang Li's laboratory, Yang Li and her classmates did not conduct any experiments, but were reading some books.

"Mr. Wan, although we majored in chemistry, we didn't have much contact with lithium in school, so what we do now is to read all the books related to lithium ions, fully understand the advantages and disadvantages of lithium, and lay a solid foundation for the future. The coming experiments are used as theoretical reserves.”

Wan Feng didn't question Yang Li's statement at all, this is what they should do.

He was really worried if they did experiments as soon as they came up. Lithium is not a good thing, otherwise Samsung's mobile phone would not become a bomb.

"Mr. Wan, we read these Chinese and foreign books. Although the lithium battery was successfully developed at Bell Labs in 1970, it has not been commercialized for so many years. Mr. Wan, are you sure that this thing can be used as a commercial battery?"

Although the lithium-ion battery was successfully researched in the 1970s, it was not until May 1991 that the real commercial use was made, and the first lithium-ion battery for mobile phones was produced by Nippon Hinashi, officially pushing the lithium battery to the market.

Of course Yang Li and the others didn't know.

Lithium is a very reactive alkali metal that provides high voltages. It can provide a voltage of 3V, while the lead storage battery has only 2.1V, and the carbon-zinc battery has only 1.5V.

Another characteristic of lithium is its lightness. It is the lightest of all metals, so light that it can float in kerosene. Moreover, lithium ions have a small ion radius, so lithium ions move more easily in the electrolyte than other large ions.

These are the advantages of lithium-ion, but it also has disadvantages.

Because of its exceptional activity, it can react with water and oxygen, and it can react with nitrogen at room temperature.

Therefore, it is very difficult to preserve it. Whether it is in water or in kerosene, it will float up and burn. Chemists finally had to force it into vaseline oil or liquid paraffin. As a result, the storage, use or processing of metal lithium is much more complicated than other metals, and has very high environmental requirements.

In summary, lithium batteries have not been used for a long time.

But these problems are not difficult for Wan Feng, although he is not a chemist and does not understand the working principle of lithium-ion batteries.

But in his last life, when he was idle and wasted on the Internet, he had studied many messy things. He had no other purpose but curiosity, and wanted to see how those messy things work and what they are used for. material.

These messy things cover almost 360 lines, ranging from needles and brains to rockets and missiles.

Some of them are forgotten after a long time, but he still remembers the things that are closer to his rebirth.

The lithium battery is probably the thing he remembers more.

Lithium-ion batteries have been Baidu several times, and some general things are more or less impressive.

When lithium-ion batteries are used on a large scale, they are composed of positive and negative electrodes, separators and electrolytes. Graphite and carbon are used for the negative electrodes, lithium cobalt oxide is used for the positive electrodes, and organic solvents such as lithium salts are used for the electrolyte.

Wan Feng knew all these things when they were written, but Wan Feng didn't know how to combine them. Anyway, when Yang Li and the others were formally experimenting, they would add a casual reminder to them, maybe they would succeed.

"Don't worry, I'm here this time to ask you, our laboratory building is completed, how many offices and laboratory storage rooms are divided into your chemistry group, you can see where your laboratory is located Best, then make a list of all the experimental equipment, materials, etc. that you need, and the company will purchase them. If you don’t have them in your country, you can get them from the Soviet Union. You must hurry up. I will bring these lists with me when I go to Longjiang again. Walk."

"Okay! We'll do this right away."

"It's better to write it in detail, and we can do it all at once, so as not to have to look for it all over the place."

Wan Feng felt that buying these things would cost him a lot of money, and it was definitely not something he could get back with a small amount.

Of course, if this amount is done on the Soviet side, it will be greatly reduced.

Seeing that it was already noon, Wan Feng drove to Wahou Daji to pick up Zhan Honggui and the others. He would show them around his factory in the afternoon.

After seeing Zhan Honggui and the others, Wan Feng took them to a snack bar, ordered a few small dishes and had lunch.

"I will take you to visit my factory in the afternoon."

"Didn't you say that your factory produces motorcycles? Is it true?" Wang Zhonghai questioned.

"Are you here these two days just waiting to die? Do you know the truth even after hearing it? Let me tell you, there are two types of motorcycles produced here. Have you seen Jiangwei 70? Have you seen Nanwan 100? ?”

Wang Zhonghai nodded.

Wan Feng turned to the Wahou Machinery Factory a few hundred meters away from the window and said, "Did you see that factory with smoke coming out of the chimney? That factory produced Jiangwei 70, and they now have a production capacity of 300,000 units."

"Is Jiangwei 70 produced by that humble factory?"

"This is the main factory. A branch factory was built in Yawan last year. Otherwise, there would be no output of 300,000 units."

"Your place is really a magical place, you can make anything." Zhan Honggui admired sincerely.
