Starting Off With A Blacksmith Workshop Chapter 168

Among the main parts of electric vehicles, the battery is the first to be solved, which is the main factor that determines the mileage.

At present, there are several types of batteries on the market, lead-acid batteries, nickel metal hydride batteries and lithium-ion batteries.

Lead-acid batteries are mainly used in current electric bicycles, and 95% of the electric bicycles running on the streets and alleys use this kind of battery.

Ni-MH batteries are mainly used in hybrid vehicles, and brands such as Ford, Honda, and Chevrolet use this type of battery.

In the end is the rising star lithium-ion battery, which is also the main energy source of pure electric vehicles on the market.

One of the electric cars with a license plate that has carried it forward in the market is that it can't stop the license plate. Of course, many domestic brands have followed suit.

The most popular at this stage is undoubtedly a small car from Wuling, which uses lithium batteries.

Now the most commonly used and the largest amount of lithium batteries are also divided into lithium iron phosphate batteries and ternary lithium batteries.

These two batteries have not been distinguished so far, and it can only be said that each has its own advantages and disadvantages.

The most important batteries are these three types now, and there is also a graphene concept battery on the market now,

But this kind of battery is often said now, and it is really just a concept. What is widely said to be a graphene battery on the market should be called a black gold battery.

What is the black gold battery? In fact, the positive electrode material is an alloy with graphene added, not a pure graphene battery, but only a little graphene additive is added to the positive electrode on the basis of the lead-acid battery.

The real graphene battery is actually a lithium battery, but it is a lithium battery that exists as a negative electrode material in the battery.

Thinking of these types of batteries, of course he has to choose a main strategy direction,

Lithium batteries are the most suitable for use in electric vehicles. The main problem to be solved is the capacity of lithium batteries, and at the same time, the discharge current of large currents must also be taken into account.

Of course, it is necessary to solve the problem of the number of full charge and discharge times. The number of full charge and discharge times of a general ternary lithium battery can reach about 800 times.

When it reaches 800, its battery capacity may become smaller, becoming only 80% of its original capacity,

The batteries used in electric vehicles have to face the release of large currents, which makes them undergo more severe tests.

So after he selected the lithium battery as the research direction, the three problems he had to solve were capacity, high current discharge and charge and discharge times.

With the direction, everything becomes easy to say, don't forget that he is a man with analytical eyes,

In the following time, he began to specialize in solving three problems. In fact, it was three problems, but in fact it was only two problems.

As long as the negative electrode material is replaced with pure graphene in lithium batteries, the two problems of battery capacity and high current discharge will be solved.

And after these two problems are solved, it is the problem of low charge and discharge times unique to graphene lithium batteries.

This night, three years have passed, and his research on graphene materials has just begun.

The next day, I ran to the company early in the morning, dragged Liu Xiaodong and ran outside,

As for Liu Xiaodong, he was dragged to the company's parking lot with a dazed expression and didn't know what happened.

When he managed to catch his breath and was about to ask something, Li Zhenhua held his head and stuffed him into the car that he had replaced with a Shelby GT500.

Immediately afterwards, before he could react and the seat belt hadn't been fastened, he heard the roar of his own car's engine.

The 5.2L, V8 engine and the unique production of the supercharged engine reached his ears, which made the invisible flesh on his face tremble, and he hurriedly put on the seat belt.

Feeling the feeling of pushing back, his whole body was pressed against the seat.

This is also the first time that Li Zhenhua used this kind of ejection to start in reality. The car quickly left the factory and drove towards the south.

Liu Xiaodong, who finally regained his strength, took a deep breath before speaking.

"Brother, please drive slowly, I haven't lived enough yet, you can't let Wang Mei become a widow at a young age,

I don't want someone to sleep with my wife, use my property, and beat my baby in the future.

Calm down, slow down, slow down, slow down!

Hey, that's right, that's right, why are you driving so fast? "

Li Zhenhua, who drives fast, has never discovered that this fat man actually has some talkative attributes. If he hadn't been driving fast this time, he really wouldn't have forced this attribute out of him.

His speed also slowed down when Liu Xiaodong was speaking.

"Fatty, let's go to buy a car, today we have to buy a lot of cars, it's really impossible if we don't hurry up!

After all, there are quite a lot of shops to visit! "

After he finished speaking, Liu Xiaodong, who was already very confused, became even more confused now.

'His old Poussin is finally willing to change? I got the hang of it and went to buy a car.

Ugh? No, you have to go to a lot of shops, this is not taking money as money! '

With this in mind, Liu Xiaodong asked him.

"Is this the attribute of your nouveau riche who finally can't bear it? What car are you going to buy?

I'll give you a staff officer. In fact, just buy a car that can block your face.

And you see, when I usually go out, don't I leave this gt500 at home to collect ashes? It's still four circles long. "

As soon as the two talked, the car was about to leave the boundary of the village of calligraphy and painting at a very high speed.

"I didn't buy a car for myself this time. I went to buy scientific research materials. I just checked when I was eating in the morning.

The cars in the F7 Motor City are quite complete, and the voice of the lady over there is quite nice.

Especially the sales crown, let's go there for a stroll.

Try to buy all the pure electric vehicles today and get them back! "

At this time, Liu Xiaodong finally understood what he meant. He really planned to buy a car, and the one he bought should be used for dismantling and researching.

It's just that the things mentioned in the middle are a bit interesting. What kind of F7 car city, the little sister surnamed Qiao, this fat man said he didn't understand at all!

"I've only been talking to you for a few days, and you're starting to do it now? It's pretty fast!

But didn't we talk about developing electric motorcycles? Why do you want to buy so many new energy vehicles! "

"Hey, the big difference is not bad, they are all about the same, the electric motorcycles on the market don't have much reference value,

There are only two that have reference value, one don't touch my big pedal, and the other is Harley's street car, but it's not easy to do in China, so let's work **** the four-wheeled car first,

When I research this thing thoroughly, is electric motorcycle still a thing?

Feel at ease! "

While chatting, the two drove towards their destination.

The 60-kilometer journey was driven by him, and he arrived at the place in less than half an hour.

After arriving at the destination, a Shelby drove into the car city, which was still very eye-catching. All the salesmen in the car city looked helplessly at the people in the car outside, their eyes shining brightly.

As soon as the two entered the Auto City showroom, a gorgeous sales lady in a slim suit stood in front of them,

Bending and bowing at the same time, the scene almost made the little stick lose control, especially when the deep V neckline bowing belt was tight.

The two were dazzled as if they had walked into the concubine selection scene.

On the other hand, Liu Xiaodong poked his waist and whispered something in his ear.

"I figured out that when I came to Shuicheng to play, why did one of the technicians I had a regular appointment with disappear? It turned out that they all came to Checheng as salesmen.

This can be regarded as a way out, it is all sales, but in the past it was me who sold myself, but now I am using myself to sell cars! "

Liu Xiaodong's words made him instantly understand something, and he nodded calmly. It seems that he saw an acquaintance in the sale of this plate.

Afterwards, the two chose the best-looking one at the concubine selection site, and let her walk around the exhibition hall with her.

And the one who was chosen was actually not at peace in her heart, two of them, and she was the only one chosen,

I don't know what to do tonight, but when I think of the commission for selling the car, I'm ruthless,

I can't bear to lose my body and can't sell the car.

In the following time, Li Zhenhua talked about the model, and the salesman took the two of them to see, such as the Madou 3 that couldn't stop the car, the Han of BYD, etc., and finally looked at the Gameboy.

But for this sale, she regretted it a bit, because the two of them have not said to buy any cars so far, and all the cars they saw were new energy, so she would not get one if she sold it like this. What a commission!

But since this is already the case, I can only bite the bullet and continue to introduce.

After walking around for a while and returning to the front desk of the exhibition hall, the sales lady's legs were almost slack, but she didn't see these two people buying a car.

Just when she was about to speak, she heard the thin man opposite.

"Miss, do you remember the models I just saw?"

The little sister looked at him with some doubts, but nodded.

"Well, go to your manager to prepare a contract. I want all the cars I have seen before."

As soon as he said these words, the expression on the young lady's face immediately changed. This was a big surprise.

This is much more profitable than selling a luxury car. UU Reading www.uukanshu.com How many cars did the other party see just now?

Ten or twenty? The young lady arranged the two of them, and then quickly ran to the manager's office.

The order of so many vehicles also attracted the attention of the manager here, and trotted all the way to the two of them.

Of course, the young lady just followed behind as well. Li Zhenhua looked at the manager who was nodding and bowing, and the salesman behind him who was frowning at him, and suddenly felt that something was going to happen behind him.

He struggled in his mind for a long time, and then said to Liu Xiaodong who was beside him.

"Fatty, I'll leave the rest to you. You can figure it out. If our company's department is short of cars or something, let's buy them together today.

The sales of the cars I ordered are counted on the sales just now, and you have the final say on the rest.

I won't stay here any longer, I'll leave in one of them first. "

After saying this, he walked directly into the exhibition hall.
