Start with a blacksmith shop

A smile appeared on Liu Xiaodong's thinned face, a smile that all men understand.

In the showroom, he looked for the largest car among them based on his memory, and the sales girl behind him followed behind him, holding a stack of car license plates in her hand.

Seeing the Gaohe he picked out, he quickly pulled out the two license plates belonging to this car from a pile of license plates.

He ran to him and handed over the two temporary cards, but he did not pick up the two temporary cards.

"Go and tell your manager first, sign the car purchase contract for this car, and let my brother give the money first.

I'm in a hurry, so I have to drive this car back first! "

After passing the salesman to the front, he took a closer look inside the car.

The overall feeling of the car is that of high-end technology. For those who don't like it, these things may seem a bit gaudy, 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 hands.

Even the 7cm stiletto heels could not stop her running speed.

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

For the subsequent listing and transfer, I will take you to the Vehicle Administration Office. "

As a result, the other party handed over the document bag and threw it into the second row of the car. Without being polite to the salesman, he walked directly to the second row and sat down.

"Okay, since you are responsible for the transfer, you can drive the car, and I will just take charge of the ride!"

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

After getting in the car, I took off my high heels, got in the car and left the showroom, heading towards the vehicle management office.

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

Instead, he made a sensible turn on the road and drove onto a deserted road.

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

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

As he said this, he walked from the driver's seat to the second row, and then the battle started, and the car also rose and fell.

That is to say, there is no one nearby. If there is anyone, they will definitely see a pair of long legs wearing high heels appearing in the car window.

After the battle, the sales girl swallowed what was in her mouth, cleaned up all traces, put on her flat shoes again, opened the window all the way, and headed towards the DMV.

For him, this incident was just a quick snack. No matter how delicious the food at home is, he will get tired of it all the time. It feels good to adjust the taste occasionally.

The vehicle management office is very efficient. It should be that the car city has taken a special approach here.

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

I made a phone call with Liu Xiaodong on the way, and the two made a brief confession, and then drove home with peace of mind.

This Gao He Zong drives well, and the interior is full of technology. It is worthy of being one of the Three Musketeers of the Internet. The gadgets created by Ding Sanshi are always at the forefront of the times.

The car did not drive directly back to his new home. Instead, it drove directly into the Summer Town factory, where he built a workshop specifically for himself.

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

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

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

Then he went straight to the bathroom, took a quick shower, dressed in work clothes, came to the car, and lifted up the car that had just left the showroom.

Before this car left the factory, I never expected that its life would be so bumpy.

As soon as he was bought, he was used to start a war. After the war, he would be dissected on the operating table.

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

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

His operation can be said to be steady and steady, and it can be said to be a high-standard procedure for wiping the mouth after eating.

When she got home, Li Yun had come back long ago and had already prepared dinner. She was eating, watching TV shows, and sleeping as usual.

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

But the scene he showed up at this moment was quite different. He saw only an empty grassland,

His location is filled with bookshelves, and around the edges of the bookshelves are circles of new energy vehicles.

This can be regarded as a reminder to himself. As long as he clears all the books on the bookshelf, 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 due to collusion in advance.

And in this half month, he finally got the battery out,

What battery? He 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 movement characteristics of lithium ions that can shuttle between graphene and electrodes at high speed and in large quantities.

There are two battery giants in Kyushu that are ranked among the best in the world. One of them 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 their products. One is lithium iron phosphate, and the other is ternary lithium.

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

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

It is also safer than ternary lithium, and has obvious advantages in bulging and catching fire.

The shortcomings are also obvious. The energy density is relatively low, the charging capacity is not as fast as ternary lithium, and the yield is low.

These two fully mature lithium batteries have not become his first choice, and he has not thought about upgrading these two batteries.

Instead, they took a different approach and chose an emerging material - graphene. What is unique about this material?

It all starts with graphene. After thirty years, with the help of his analytical eye, the battery he created 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 still depends on the specific debugging. The best state after final adjustment is the maximum value mentioned above.

Why do you have such perverted attributes? Let’s start with the material graphene.

Graphene is a single-layer two-dimensional honeycomb structure material in which carbon atoms are closely packed. Simply put, it is a network structure.

Because of its extreme thinness (only one layer of atoms thick), there are very few restrictions on the movement of cations.

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

During the production of general batteries, special additives must be added to the electrolyte first to remove trace amounts of water to avoid decomposition of the electrolyte caused by high temperatures.

The cathodes of ordinary batteries generally use large single crystal ternary materials to improve the thermal stability of the material.

The graphene he used is very different. He believes that the unique physical properties of graphene,

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

Compared with ordinary batteries, fast charging, 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 mass production is carried out.

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

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

Numerous phenomena are formed, and the battery charges and discharges faster and faster.

Graphene is particularly suitable for this process at this point, and it is not an exaggeration to say that it is cheating.

At present, the lead-acid batteries used in electric bicycles are very slow to charge, and the time required is often several hours.

The ternary lithium battery charges ten times faster than this kind of lead-acid battery, especially with the advent of fast charging technology in recent years, that is, high-voltage and high-current charging, which can be fully charged in just one or two hours.

The charging speed of the battery he created this time is 80 to 200 times that of the normally used ternary lithium battery.

Outrageous? Outrageous, outrageous!

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

Dozens or hundreds of times faster. Taking the example of a car that cannot stop, it takes 20 minutes for his supercharger to charge to 50% and 80 minutes to fully charge.

And 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 charged to 80% in less than one minute, and the remaining 20% ​​of power can be charged in the charging protection mode, which will not take more than three minutes.

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

It only takes a few minutes to refuel, and now it only takes a few minutes to charge, and the biggest car use restriction is solved.

Can you say that this battery is not outrageous? Not perverted?

This is quite a black technology!
