Start a blacksmith shop

Chapter 171
There was a smile on Liu Xiaodong's thinned face, it was a kind of smile that all men could understand.

In the exhibition hall, according to the memory just now, I found the largest car among them, and the sales lady behind him followed behind, holding a stack of car license plates in her hand.

Seeing the Gaohe he picked out, he quickly pulled out two cards belonging to this car from a stack of cards,

He ran to his side and handed over the two cards, but he didn't go to accept the two cards.

"You go and tell your manager first, sign the car purchase contract for this car first, and let my brother give the money first,
I'm in a hurry, so I have to drive this car back first! "

Sending the sales to the front, he himself carefully looked inside the car,
The overall feeling of the car is a sense of advanced technology. For those who don't like it, these things seem a bit gimmicky, but this does not hinder the display of technology on this car.

Soon the sales lady ran over with all the information about the car in her hand,

Even those 7cm stiletto high heels couldn't stop her running speed.

"Sir, I have brought all the documents here, now you can drive this car directly, and you have applied for the license plate in advance.

I will take you to the vehicle management office for the listing and transfer of ownership later. "

As a result, the file bag handed over by the other party was thrown into the second row of the car, and he didn't show politeness to the salesman, and went straight to the second row and sat down.

"That's fine, since you are in charge of the ownership transfer, you can drive the car, and I'll just take care of the car!"

The salesman nodded, and told him to wait a moment, and when the salesman came back, he was carrying a pair of flat shoes in addition to the bag he was carrying.

After getting in the car, he took off his high-heeled shoes, got in the car and left the exhibition hall, heading for the vehicle management office.

The car got out of Checheng, and after driving for a while, the young lady driving in front did not go straight to the car management office.

Instead, he sensibly turned a corner on the road and drove onto a small road with no one there.

The car stopped, put on the high heels again, took out a document from his bag and handed it to him.

"This is my medical report, please rest assured to accept my next service, sir, and leave everything to me!"

As he spoke, he came to the second row from the driver's seat, and then the battle started, and the car rose and fell with the ups and downs.

That is to say, there was no one around, and anyone would definitely see a pair of long legs in high heels appearing on the car window.

After the battle, the sales lady swallowed what was in her mouth, cleaned up all the traces, put on her flat shoes again, and walked towards the vehicle management office with the windows open.

For him, this incident is just a quick meal. No matter how delicious the food at home is, it will always get boring after eating. It feels good to reconcile the taste once in a while.

The efficiency of the vehicle management office is very high, it should be that Checheng has taken a special way here.

After all the formalities were completed, he drove directly towards home. As for Miss Surprised, she had nothing to do with him after completing the vehicle formalities.

On the way, I made a phone call with Liu Xiaodong, and the two made a simple confession, and then drove home in peace.

The driving of this Gaohe is not bad, and the interior is full of technology. It is worthy of being one of the three Internet Musketeers. The gadgets made by Ding Sanshi are always at the forefront of the times.

The car did not drive directly back to the new home, but instead drove directly into the Shuzhen factory area, where he built a workshop specially for himself.
It is said that it is a workshop, but it is actually a laboratory that belongs to him.

The laboratory configuration is not low. Some of the equipment he usually uses has been moved here, and a room dedicated to him to rest has been built in the laboratory.

After parking the car, he threw all his clothes into the washing machine with a dryer,

After that, he went straight to the bathroom, took a brief shower, put on work clothes, came to the side of the car, and lifted the car that had just left the showroom.

Before this car left the factory, I didn't expect that its life would be so rough.

Just after being bought by someone, he was used to start a war. After the battle is over, what awaits him is to be dissected on the operating table.

This time his purpose is very clear, which is to drain all the brake fluid and gear oil, and then make him look dirty.

When his body was covered with oil, he dropped the tools in his hands, walked out of the factory area in his work clothes, and walked towards home.

His operation can be said to be stable, and it can be said to be a high-standard mouth-wiping process after stealing food.

By the time they got home, Li Yun had already returned, and she had already prepared dinner. As usual, she ate, watched dramas, and slept.

Entering the virtual laboratory again, he continued the research on lithium batteries.

But the scene he manifested at this moment is quite different. I saw an empty grassland,
His place is full of bookshelves, and around the bookshelves are circles of new energy vehicles.

This can be regarded as his urging to himself, as long as all the books on the bookshelf are cleared, the cars outside the bookshelf will also become his next target.

As time passed day by day, half a month had passed since he went to Shuicheng to buy a car. He and Liu Xiaodong passed the test safely because of collusion in advance.

And in this half month, he finally got the battery out,
What battery?He himself gave the battery a very easy-to-understand name,
The principle of the super graphene lithium-ion special battery is also very simple. It is a new energy battery with high energy density developed by utilizing the high-speed and large-scale shuttle movement characteristics of lithium ions between graphene and electrodes.

In Kyushu, there are two battery giants that can be ranked in the world. One of them is Dening Times, and the other is a battery manufacturer pretending to be a car company.

The two of them are in a competitive relationship, and there is also a gap in their products. One is lithium iron phosphate and the other is ternary lithium.

As mentioned above, these two types are the most widely used lithium battery types in the world.

Compared with the two, lithium iron phosphate has an advantage in price, and in terms of performance, compared with ternary lithium batteries, the performance attenuation after long-term use is smaller.

In addition, it is also stronger than ternary lithium in terms of safety, and has obvious advantages in swelling and fire.

But the disadvantages are also obvious. Relatively speaking, the energy density is low, the charging capacity is not as fast as that of ternary lithium, and the yield is low.

These two fully mature lithium batteries did not become his first choice, nor did he think about upgrading these two batteries.

Instead, they chose another emerging material - graphene, and what is unique about this material?

It all starts with graphene. After 30 years of this time, with the help of the analytical eye, the battery he made can be said to be extremely abnormal.

The charging speed is between 80 and 200 times that of ordinary lithium batteries.

The total capacity of the battery is 5 to 8 times that of lithium batteries on the market.

Of course, it still depends on the specific debugging, and the best state after the final adjustment is the maximum value mentioned above.

Why is there such a perverted attribute?Let's start with the material graphene.

Graphene is a single-layer two-dimensional honeycomb structure material formed by densely packed carbon atoms, which is simply a network structure.

Because of the extreme thinness (only one layer of atoms thick), the movement of cations is very limited.

At the same time, because of its network structure, the electrode material made of graphene also has sufficient pores.

In the production of general batteries, special additives must be added to the electrolyte to remove traces of water so as to avoid the decomposition of the electrolyte caused by high temperature.

The positive electrode of ordinary batteries generally uses large single crystal ternary materials, so as to improve the thermal stability of the material,
The graphene he used is very different, thinking that the unique physical properties of graphene,

It can quickly dissipate the heat generated by lithium ions during movement, and greatly improve battery performance.

Compared with ordinary batteries, fast charging speed, long service life and large battery capacity are the three major advantages of graphene.

And after mastering the method, the cost is relatively low when it is prepared in large quantities.

Looking at the charging and discharging process of the battery, in essence, it is a process of 'embedding' and 'detaching' a cation in the electrode.

So the more holes there are in the motor material, the faster the process will go,
Numerous such phenomena have formed, and the performance of battery charging and discharging is getting faster and faster.

Graphene is in line with this process at this point, and it is not an exaggeration to say that it is open and hanging.

At present, the charging speed of lead-acid batteries used on electric bicycles is very slow, and the required time is often several hours.

The charging of ternary lithium batteries is ten times faster than that of lead-acid batteries, especially with the rapid charging technology in the past few years, that is, high-voltage and high-current charging, which can be fully charged in just one or two hours.

And the battery he made this time is 80 to 200 times faster than the usual ternary lithium battery in terms of charging speed.

Outrageous?Outrageous, off the mark!

Outrageous is no longer enough to describe such a speed, it can be described as abnormal.

Dozens of times to a hundred times the speed, taking the unstoppable car as an example, it takes two to ten minutes to charge his super charging pile to 50%, and eight to ten minutes to fully charge it.

And what about the graphene battery he made this time?This is at least 80 times faster than the charging speed of ternary lithium.

That is to say, based on the minimum time, the battery can be charged to 1% in less than 80 minute, and the remaining 20% ​​of the power can be charged in the charging protection mode, which will not exceed 3 minutes.

What does this show?This shows that as long as there are enough charging piles on the road, cars equipped with such graphene batteries can completely replace fuel vehicles.

It takes only a few minutes to refuel, and now it takes only a few minutes to charge, so the biggest car usage limit is solved.

Can you say that this battery is not outrageous?not perverted?
This is a proper black technology!
