Technology overlord starts with new energy vehicles

Sitting down at the table of the R\u0026D personnel, Xu Yifan was not polite, picked up a pair of unused chopsticks, and hurriedly picked up several mouthfuls of food.

After eating the food, he raised the green stick in his hand to several battery R\u0026D personnel at the same table.

"Brothers, let's go!"

"drink!"

Immediately, several researchers raised the wine bottles at hand, drinking and drinking, drinking and drinking, and toasted and drank together.

During this period of time, Xu Yifan and several R\u0026D personnel have become very familiar. They are all in their twenties and thirties, and they often go to eat supper together and make skewers.

Occasionally, we will wash our feet together and have a massage!

Everyone has been surprised by this.

After taking a heavy sip of beer, Xu Yifan continued to chat with everyone as usual.

"It's almost Chinese New Year, how time flies!"

"In a blink of an eye, everyone has been coming to our company for several months."

"Well, it's the end of the year, is there anything you want to tell me?"

Xu Yifan asked with a smile.

Several developers said boldly.

"There's nothing to say, it's all in the wine!" A researcher raised the beer bottle and took a big gulp.

The rest of you also talked about your feelings in the Kyushu factory in the past few months.

"Working in our factory is very happy, there is no intrigue, and no layman directs the insider."

"The main reason is that Mr. Xu is so kind!"

"Well, apart from the fact that the laboratory equipment is not interesting, there is nothing to say about life."

"Yes, yes, I didn't expect to make so much money in a few months!"

"To be honest, I've never heard of a brother or sister who has a better working and living environment than ours. Mr. Xu would accompany us to drink, have skewers, and wash our feet from time to time!"

"The salary is also high. To be honest, I am a little embarrassed to get such a high salary!"

During the last wave of technological breakthroughs, several R\u0026D personnel directly earned more than 300,000 yuan, and with the salary of these months, they have a deposit of nearly 400,000 yuan!

It's only been less than half a year. If you have this income for the remaining half of the year, your annual salary will be one million!

This kind of salary is already the annual salary of the top researchers, especially there are several graduate students among them.

Everyone is naturally very satisfied with this.

"As long as everyone lives well here, I believe it will get better and better in the future!"

Raising his wine glass, Xu Yifan touched with several R\u0026D personnel in a void.

After taking a sip of beer, he said with some embarrassment.

"By the way, I have a heartfelt request for this year's holiday."

Guessing that there may not be a holiday, everyone showed hesitation.

Lu Jingping took a sip of beer and smiled: "Mr. Xu, just tell us what the arrangement is. I believe you will never treat us badly!"

After hesitating for a moment, remembering everyone's usual relationship with each other, this Mr. Xu has considered everything, and everyone was relieved and asked directly.

"Yes, yes!"

"If you have anything to say, just say it directly, we are not outsiders!"

With a sigh, Xu Yifan continued talking to everyone.

"Everyone already knows the current situation of our factory."

"What I would say is that today's scene is like cooking oil on fire. It looks like prosperity, but it's just a false prosperity. It can easily be destroyed."

"Our factory is about to face a huge crisis!"

"Now our product Kyushu mini does not have its own core technology after all, and the factory is just a small factory with little reputation."

"Now Kyushu Mini is just a local enterprise in a small fifth-tier city, except for the locals who have heard of this brand.

Looking at the province and the whole country, Kyushu is just a very small local enterprise with no reputation at all. "

Several R\u0026D personnel listened quietly, Xu Yifan took a sip of beer and continued.

"Our factory can have what it is now. First, our products are more conscientious. Second, we have found a blank market."

"But the market is too big, and it's not something that our small factory with insufficient production capacity and no reputation can fully eat.

Next year, as our shipments increase, there will definitely be large car companies looking at our market.

At that time, if there is a certain big car brand that wants to compete for this market, then we will not have any competitive advantage!

The first point is that we are not well-known, if a certain car manufacturing brand also comes to enter this field.

When consumers choose a company they have never heard of, or a domestic brand or even a joint venture brand, they will definitely trust the brand they have heard of before.

This is the first point, the second point.

We have too few stores, and now there is only one in this city. How can we compare with those big car companies with 4S stores all over the country.

In just a few months, they can put cars similar to our Kyushu mini in brand stores across the country for sale.

At that time, the entire blank market will be quickly eaten away! "

"Joint ventures may not come, but domestic brands will definitely come, such as those brands that can't sell many cars a year, Shuanghuan Motor, Hafei Motor, Lifan Motor, even Chery, BYD and so on!"

According to Xu Yifan's description, several researchers thought about it, it seems that this is indeed the case, the Kyushu Automobile Factory is in danger!

Several R \u0026 D personnel present here are a little sighed.

"It turns out that our factory is so dangerous, I've always been more optimistic."

"I also thought that our factory was very profitable. I even wanted to buy a Kyushu mini to drive. It would be nice to drive around the city if I have nothing to do."

"The car needs of the elderly."

"A blank market is like a big cake. It's okay if no one has discovered it before. Now that it has been discovered, competitors will definitely be introduced."

After several R\u0026D personnel sighed, it was Lu Jingping who asked, "I don't know how you should deal with Mr. Xu?"

Since Xu Yifan can understand the problem himself, there must be a solution. Everyone is engaged in research and development, not economics and sales!

After trying the stewed prawns made by the chef, the taste is not bad, Xu Yifan replied.

"It's all up to you, Kyushu Factory must have its own core technology!

Let our products have advantages that other products of the same type do not have, and other car manufacturers cannot imitate the manufacturing technology in a short time. "

Stretching his chopsticks towards the braised carp, he took a big mouthful of the meat dish and took another sip of the wine, Xu Yifan continued.

"For the new energy vehicles we manufacture today, the three-electric system is the top priority.

Batteries, motors, electric controls.

Lithium iron phosphate battery can make the vehicle last longer, output more power current in a short time, and abandon the shortcomings of traditional batteries that are easy to age and need to be replaced in about two years.

The motor is equivalent to the engine of a traditional car. How much horsepower the vehicle can explode and how many kilometers the top speed can be maintained are all the functions of the motor.

The electronic control system fully allocates the transmission between the battery efficiency and the motor. A good electronic control system is responsive without the slightest delay, and the power is on call.

The reason why some good cars are easy to drive is largely due to their responsiveness, and the power will come up immediately with a touch of the toes.

However, some vehicles react slowly after stepping on the accelerator, or the power output fluctuates after stepping on the accelerator, which makes it difficult for people to feel easy to drive! "

Drinking, eating vegetables, cold pig ears are also good!

Xu Yifan continued to talk to several R\u0026D personnel who had stopped their chopsticks and listened carefully to what he said.

"Battery, motor, and electronic control, these are the three pieces of the new energy vehicle puzzle.

As long as these three pieces of the puzzle are put together completely, a new energy vehicle that is no less than a traditional fuel vehicle can be created, and the technology can even go further to achieve an overtake of ordinary fuel vehicles!

Among them, the battery is the most important thing, if we have an excellent battery.

It can achieve a longer cruising range, two hundred kilometers, three hundred kilometers, or even longer!

So even if some other big brand cars also enter this field, we have the strength to fight with them! "

It wasn't until Xu Yifan finished speaking that everyone came back to it.

"This, I understand!"

"Suddenly feel that working overtime is not impossible!"

"Our work is so important. I thought it was just icing on the cake. Ordinary lead-acid batteries can also be used."

"If the Jiuzhou factory is gone, I don't know where to find such a well-paid job and such a good boss!"

"Naturally, we should contribute to the company!"

Holding up the bottle to everyone, Xu Yifan took a sip of beer. "Thank you for your understanding!"

"Of course, I'm not an unreasonable person!"

"In this way, I think our battery research and development has basically entered the final stage, and it should be completed in less than two months."

Xu Yifan asked Lu Jingping who was in charge of the entire research and development project.

Lu Jingping thought for a while and said solemnly: "Yes, if it is soon, it may be about a month."

"That's good. There is no way for everyone to go home and reunite with their families during the Chinese New Year. I will give you a subsidy of 10,000 yuan per person. If you need it, you can bring your relatives and friends over to celebrate the New Year.

In addition, when this research and development project is completed, I will give everyone a month's paid vacation to make up for the compensation for not being able to go home and reunite with relatives during the Chinese New Year! "

As soon as the solution came out, everyone breathed a sigh of relief.

Even if there is no compensation, everyone will do their best to share the burden for the factory, but who doesn't want to rest or spend time with their families.

This is very good, although there is no way to go home immediately, but you can make up for it later, everyone can understand the priority of things.

Everyone raised the cups in their hands and said solemnly.

"I will definitely go all out!"

"I knew Mr. Xu would never treat us badly!"

"Take a week's vacation for a month's vacation, we earned it!"

"President Xu, don't worry, after dinner, we'll go back to work!"

Holding up about one-third of the beer left in his hand, Xu Yifan signaled to everyone: "Thank you for your understanding, I did it, you can do whatever you want!"

Gudong Gudong, drink it dry in one gulp!

Seeing this scene, everyone also put away the beer or drinks in their hands.

Drink it all in one gulp!

After drinking and eating some food, Xu Yifan asked Lu Jingping beside him, "Our battery research and development is nearing completion. If we want to build a battery factory next, what equipment will we need?"

"Building a factory?" Lu Jingping was a little surprised.

Xu Yifan said affirmatively: "That's right, some large-scale equipment and technical personnel reserves, I think about it earlier, it's better to purchase it in a hurry than when it is needed, and it can save a lot of preparation time in the later stage!"

"In terms of factory construction, the overall lithium battery manufacturing process can be divided into the front-end process of pole piece manufacturing, the middle-end process of cell synthesis, and the back-end process of packaging.

The production goal of the front-end process is to complete the manufacture of positive and negative electrodes. The main processes are: mixing, coating, rolling, slitting, sheeting, and die-cutting.

The equipment involved mainly includes: mixer, coating machine, roller press, slitting machine, sheeting machine, die-cutting machine, etc. . . . . "

"There are many methods for preparing LiFePO4 cathode materials, which can be roughly divided into liquid-phase methods and solid-phase methods.

The liquid-phase method includes co-precipitation method, hydrothermal method, sol-gel method and other low-temperature synthesis methods.

Solid-phase methods include high-temperature solid-phase sintering, carbothermal reduction, and microwave sintering, each of which has different advantages and disadvantages. . . . . "

Lu Jingping mentioned various preparation schemes.

Xu Yifan finally chose to use the high-temperature solid-phase method.

The preparation method of this positive electrode material has the advantages of simple process, easy industrialization, easy removal of decomposition products to reduce impurities, easy control of preparation conditions, and relatively low equipment prices.

The disadvantage is that the crystal size of the positive electrode material produced is relatively large, the phase is uneven, and the calcination time is long at the same time, etc., and the new lithium iron phosphate battery produced finally has a certain performance attenuation compared with laboratory conditions.

After deciding on the general construction plan of the battery factory in the future, Xu Yifan gave Lu Jingping time to make a list of the equipment that can be confirmed to be used, and handed it over to the purchasing department to purchase equipment.

After talking about the business, we didn't drink too much. Everyone should eat vegetables, eat and eat, and plan to go back to work after dinner!

After eating with the R\u0026D department for a while, Xu Yifan came to the dinner table next to the managers of various departments.

drink!

After this reunion dinner, everyone should have a holiday for the next week, be on duty, and work!
