Liu Xiaodong's already thin face showed a smile, which was a smile that men knew.

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

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

He ran to him and handed over the two cards, but he did not take 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!”

He took the sales branch in front, and he looked carefully inside the car.

The overall feeling of the car is a high-end sense of technology. For people who don’t like it, these things seem a bit fancy, but this does not hinder the display of technology on this car.

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

Even those 7-centimeter slim heels couldn't stop her from running.

"Sir, I have brought all the information here. Now you can drive away this car directly, and the license plate has been applied for in advance.

I will take you to the vehicle management office for the later registration and transfer."

As a result, the file bag handed over by the other party threw it into the second row of the car. He didn't be polite to the salesperson and walked directly to the second row and sat down.

"Okay, since you are responsible for the transfer, you can drive the car. I'll just take charge of taking the car!"

The salesman nodded and asked him to wait. When the salesman came back again, in addition to the bag he was carrying, he also carried a pair of flat shoes in his hand.

After getting in the car, I changed my high heels, drove out of the exhibition hall, and drove towards the location of the vehicle management office.

The car left the car city. After driving for a while, the young lady driving in front did not go straight to the vehicle management office.

Instead, I turned around very sensible on the road and drove on an unmanned path.

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

"This is my physical examination report. Sir, please feel free to accept my next service. Leave everything to me!"

As he said that, he came from the driver's seat to the second row, and then the battle started, and the car also rose and fell with its height.

In other words, there is no one nearby. If anyone is there, he will definitely see a pair of long legs in high heels appearing on the car window.

After the battle, the sales lady swallowed the things in her mouth, cleaned up all the traces, changed into flat shoes, opened the window all the way, and advanced towards the vehicle management office.

For him, this time it was just a fast food. No matter how delicious the food at home was, I would always get tired of it. It would feel good to mix the taste occasionally.

The vehicle management office has very high efficiency, so it is probably because the car city has taken a special path here.

All the procedures were completed, and he drove directly towards home. As for the surprise, the young lady had no connection with him after completing the vehicle procedures.

On the way, they called Liu Xiaodong, and the two of them simply made a confession, and then they drove home with confidence.

This Gaohe General drives well and has a strong sense of technology in the interior. It is worthy of being one of the three online musketeers. The things Ding Sanshi made are always at the forefront of the times.

The car did not drive back to his new home, but instead drove directly into the factory in Summer Town, where he built his own workshop.

It is said to be a workshop, but it is actually a laboratory of his own.

The laboratory configuration is not low. All the equipment he usually uses is moved here, and a room specially designed for him to rest is also built in the laboratory.

After parking the car, he threw all his clothes into the washing machine with drying.

Then he went straight to the bathroom, took a shower, and in his work clothes, he came to the car and lifted the car that had just left the exhibition hall.

Before leaving the factory, I didn't expect that its life would be so bumpy.

He was just bought away and used to start a war. After the war, it was not counted. What awaited him was to be dissected on the operating table.

His purpose this time was very clear, which was to release the brake oil and gear oil and make him look dirty.

When his body was covered with oil, he threw down the tools in his hand, staggered out of the factory in his work clothes, and walked towards his home.

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

When he got home, Li Yun had already come back and had already prepared dinner. She always wanted to eat, watch TV shows, and sleep.

After entering the virtual laboratory again, he continued to start research on lithium batteries.

And the scene he showed at this moment was very different, only to see an empty grassland.

His location is full of bookshelf, and the periphery of the bookshelf is a circle of new energy vehicles.

This is also his urge to himself. As long as all the books on the bookshelf are cleared, the cars outside the bookshelf will become his next goal.

As time passed, half a month had passed since he went to Shuicheng to buy a car. He and Liu Xiaodong passed the level safely because of their early confession.

And in the past half a month, he finally got the battery out.

What battery? He gave the battery a very easy-to-understand name.

The principle of super graphene lithium-ion special battery is also very simple. It is used to develop a high-energy density new energy battery with high energy density that can be developed by using lithium ions at high speed between graphene and electrodes.

There are two battery giants in Jiuzhou that can be ranked first in the world, one of which is Dening Times, and the other is a battery manufacturer disguised as a car company.

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

Both of these two types of lithium batteries have been mentioned in the previous article.

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

It is also more secure than ternary lithium, and has obvious advantages in bulging and ignition.

However, the disadvantages are also obvious. Relatively speaking, the energy density is low, the charging capacity is not as fast as ternary lithium, and the yield rate is lower.

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

Instead, we chose the emerging material - graphene, which was a different approach. What is unique about this material?

All this starts with graphene. After thirty years of experience and the help of the Eye of Analysis, 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, this depends on the specific debugging. The best state after the adjustment is the maximum value mentioned above.

Why do we have such abnormal properties? Let’s start with graphene.

Graphene is a single-layer two-dimensional honeycomb-shaped structural material formed by closely packing carbon atoms, which is simply a network structure.

Because it has an extreme thinness (only the thickness of one atom), the movement of cations is very limited.

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

In general, special additives must be added to the electrolyte during production to remove trace amounts of water to avoid the electrolyte decomposition caused by high temperature.

The positive electrode of ordinary batteries generally uses large single crystal ternary materials to improve the thermal stability of the material.

The graphene he used was very different, thinking that the physical properties of graphene were unique.

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

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

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

Looking at the charging and discharging process of the battery, it is essentially a process of cations inlaying and disengaging in the electrode.

Therefore, the more holes there are in the motor material, the faster the process will be.

Many such phenomena have formed the phenomenon of charging and discharging of batteries becoming faster and faster.

Graphene is particularly in line with this process, and it is not an exaggeration to say that it is a cheat.

At this stage, the lead-acid battery used on electric bicycles is very slow to charge, and the time it takes is often several hours.

The ternary lithium battery is ten times faster than this lead-acid battery in charging, especially in a few years, with fast charging technology, that is, high voltage and high current charging, it can be fully charged in just one or two hours.

The battery he made this time is 80 to 200 times the charging speed of the ternary lithium battery he usually uses.

Outrageous? Outrageous, outrageous!

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

At a speed of dozens or hundreds of times, taking the example of being unable to brake the car, it takes twenty minutes to charge his super charging pile to 50%, and eighty minutes to fully charge.

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

In other words, based on the minimum time, the battery can be rushed to 80% in less than one minute, and the remaining 20% ​​of the battery is charged in the charging protection mode, which will not exceed three minutes.

What does this mean? This means that as long as there are enough charging piles on the road, cars equipped with this graphene battery can completely replace the status of fuel vehicles.

It takes only a few minutes to refuel, and now it takes only a few minutes to charge, so the biggest car use restrictions will be solved.

Can you say that this battery is not outrageous? It is not abnormal?
Chapter completed!
