Lithium batteries are divided into lithium metal batteries and lithium-ion batteries, of which lithium-ion batteries can be charged and discharged repeatedly. However, the self-discharge performance of lithium metal batteries is lower, and if the closed welding is good, the service life can reach ten years, so lithium metal batteries are generally used in some inseparable equipment.

And the mobile phone battery we use every day is the lithium-ion battery. Lithium-ion batteries can be charged and discharged repeatedly, with safe and stable performance, and are essential batteries for daily electronics and electrical appliances. The world's first practical lithium-ion battery was invented by Sony.

However, there are many kinds of cathode materials for lithium-ion batteries, so the performance of the battery is also very different, and the polymerization polymer separator film in the lithium-ion battery was also invented after 2010, which is also an important material to improve the performance and safety of the battery.

Because of Shen Danqing's relationship, the Metal Research Institute began to study lithium iron phosphate battery technology as early as 92. They have been researching cathode materials for many years, experimenting with various cathode materials, and finally using carbon nanotube materials developed by the Institute of Nonmetallic Research, they added titanium oxide materials to carbon nanotubes to obtain a cathode material with very good performance. Later, Shen Danqing mentioned that they use polymer polymer materials as a separator, this special material can allow lithium ions to penetrate normally, but can prevent the penetration of non-aqueous electrolytes, so the safety performance of the battery is very stable, and it can also significantly improve the performance of lithium-ion batteries.

With these two technologies, the lithium-ion battery of Changsheng Investment Group has excellent performance and long battery life, which is far superior to other lithium-ion batteries on the market. So strictly speaking, Europe and the United States can copy out the balance car, but the battery performance can't catch up, and it may not be long before it runs out of power. In this way, there are still market prospects for balance cars. However, it cannot be denied that European and American companies will not copy the battery technology of Changsheng Investment Group.

It is also difficult to copy the lithium-ion battery technology of Changsheng Investment Group, it is a material technology, first of all, you have to have a non-metallic research institute and a chemical research institute, otherwise those two materials will not be able to start from a copycat.

When Shen Danqing was thinking, it was time to get off work, and Secretary Tang came in and reminded him: "Boss, it's time to get off work." This is a special reminder from Secretary Liu, he said that the boss will often think about problems and forget the time, but the boss must leave work on time, because the boss lady will wait for him to get off work in the garden at that time.

"Oh, so fast, then let's get off work!" replied Shen Danqing blankly, and after saying that, he stood up and walked out. Secretary Tang could hitchhike back to the community, and of course he followed immediately.

Secretary Tang has now become a pure work secretary, and he doesn't want to follow him after work, and then there are bodyguards to follow him, anyway, he won't deal with the company's affairs after work.

The next morning, Shen Danqing saw the real thing of the balance bike at Changsheng Seiko. It is not an experimental application, but a finished product sample with complete functions and beautiful appearance, because each product of the company must be approved by him before it is ready for mass production.

Since the reform of the mechanism of the research institute and the enterprises under its umbrella, each research institute has a product designer. So after they tried to produce the product, the designer basically designed the appearance at the same time, which saved time. Therefore, what Shen Danqing saw was a perfect product, which was not much different from the balance bikes of later generations, but the materials were better and the workmanship was more exquisite.

"Boss, are you still satisfied with your appearance?" asked Guo Dong with a look of hope on the side. This balance bike alone can set up an internal joint venture, and their mechanical technology research institute accounts for the largest proportion, so he will be the chairman of this internal joint venture in the future, so he cares about it.

After listening to Guo Dong's words, Shen Danqing didn't answer immediately, he squatted down and carefully inspected it before saying, "It's okay, let's officially produce it like this!"

"Is that a new company or is it put in Changsheng Seiko production?" asked Guo Dong intentionally.

"The old rule, a new in-house joint venture dedicated to production. In the future, there will be similar scientific and technological products, which will also be produced by this company. Shen Danqing said with a wave of his hand.

Hearing the boss's words, Guo Dong was finally relieved, so he boldly asked: "Then boss, can you name this joint venture! ”

"Well...... Shen Danqing said with his right hand supporting his chin, his fingers touching the bare and non-existent beard on his chin. And to the annoying question of choosing names, he had enough names! he was almost running out of the few drops of ink in his head.

After thinking for a few minutes, he finally came up with a passable name, he thought like this, this balance bike is to be smuggled to Europe and the United States, so you can't use the Chinese name that only Chinese can understand, to Chinese and English is a meaning, and it can't be transliterated, so he thought of meteors, meteors are comets, which are planets that move freely and freely, free from the shackles of galaxies. It represents the meaning of free movement, which is very suitable for the product positioning of the balance car. So he said to Guo Dong: "The balance bike is called a shooting star! As for the name of the joint venture, it will be called Envision Technology Group Co., Ltd. ”

"Meteor Vision?" Guo Dong listened to the boss's words and recalled it in his mind, thinking that it was not bad and not old-fashioned. So he smiled and said: "Thank you boss for the name, it's very good, it's not only catchy but also has far-reaching meaning." The most important thing is that Meteor also has an English word, the word is called meteor, which is very simple and foreigners can understand at a glance. ”

That's what I thought, taking a name as we understand it in China, the English noun is too long, and it becomes a hard combination, which may make a joke, so I chose such a simple name. I originally wanted to call it Hot Wheels, but how do you translate it into English!" Shen Danqing also said with a smile.

"Dean Guo, how is this control signal set up, tell me, let me try. Shen Danqing then asked Guo Dongdao.

"We've made changes based on what you said, we have set up five gears, four forward gears and one reverse gear. The first gear is five yards, the second gear is ten yards, the third gear is fifteen yards, and the fourth gear is twenty yards. Unlike a car, the start is not in first gear, but a state of slow sliding, and you have to step on the first gear before you officially walk.

Because there are four forward gears, I set up a downshift sensor that downshifts one gear every time I step on it. We set the gears on the front and back, with the feet moving forward to increase the gear, and the heel force to decrease the gear.

We designed the brakes, on the left, the left heel point is the brake. Unlike a car, this brake is applied slowly, which is to prevent a person from falling forward under the action of inertia.

The rest of the settings are pretty much the same as you said, the right heel point is the reverse gear, the right toe point is the right turn, and the left toe point is the left turn. Guo Dong explained in detail.

"Well, it's a good design, and it's in line with people's habits. Dean Guo, is there electricity?" Shen Danqing nodded in agreement, and then asked.

"With electricity, you just test it, and our battery can last for two hours on a full charge. And we used the fast charging technology you mentioned, and it can be fully charged in ten minutes. Guo Dong replied proudly. You can walk a long way in two hours, forty kilometers in twenty yards, of course! That's ideal, but you can only walk 25 to 30 kilometers. This is a scooter, just to walk around the neighborhood, such as going to the supermarket to buy vegetables in the market or something.

Shen Danqing tried a few laps in the wide corridor of the office building, and it was very stable, which really deserved to be a balance car. He deliberately tried to apply the brakes again in the case of 20 yards, and it was also very smooth, really slow braking, it seems that they used intelligent braking technology, and the braking method at each speed is different, so that the user will not fall.

"Hahahaha! Dean Guo, it's really good, I think it can be mass-produced. By the way, hurry up and make one for me, I'm going to take it back for my daughter to play with. Kids will love this stuff. When it's done, send someone to send it to the company, Dean Guo, can you do it today?" Shen Danqing played with a childlike heart, and then said with a laugh.

"No problem, as long as the design is out, it will be easy to make again, and I will send someone to bring it to you in the morning." Guo Dong said with a ticket.

Indeed, in the electronic age, as long as the design is made, the production of products is as simple as copying, and the quality will remain at a fairly high level. Although Envision has not yet been established, Changsheng Seiko can produce it. It's just that the positioning of the company is different, and Shen Danqing is divided into two companies.

"Dean Guo, then let's do it! Produce a few more films, there may be some shots that need more than one balance bike. I'm going back to the company, goodbye!" Play and play, it's important to get down to business, now that it has been accepted, Shen Danqing doesn't want to waste any more time, and says goodbye to Guo Dong.

"Goodbye!" Shen Danqing finished speaking and left. Guo Dong just said goodbye to his back.

The drone has not yet been developed, mainly because Shen Danqing's requirements are too high, and he must keep the flight flat even when there is wind. The body is so light, the software engineer of SoftNews really wants to cry without tears.

Shen Danqing's early application of intelligent drones is for filming. As for the use of express delivery, it cannot be achieved without electronic maps and positioning technology.

The most important thing in shooting is stability, which is why he put forward such strict requirements. It's not to deliberately embarrass them, but it's true.

Back at the company, Shen Danqing first went to the 20th floor to tell the good news to the dragon company, and then returned to the office on the top floor.

At this time, Li Zhengyu is no longer in the company, and he is shooting future smart life advertisements in the community. Speaking of advertising, the Chinese New Year is approaching, and the advertisements of various enterprise groups have to be filmed again, and the advertisements for the New Year are different, so the dragon company is very busy during this time and has stopped making movies.
