A smile appeared on Liu Xiaodong's already slimmed down face, which was a kind of smile that all men understand.

In the exhibition hall, according to the memory just now, he found the largest car, and the sales lady behind him followed behind with a pile of car license plates in her hand.

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

Ran to his side and handed over the two Pro cards, but he didn't pick up the two Pro 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'll have to drive this car back first! ”

Turning the sales branch to the front, he himself took a closer look inside the car.

The overall feeling of the car is a high-level sense of technology, for people who don't like it, these things seem a little bells and whistles, but this does not prevent the display of technology on the car.

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

Even the 7-centimeter stiletto heels couldn't stop her from running.

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

I will take you to the DMV for the transfer of ownership later. ”

As a result, the other party handed over the document bag and threw it to the second row of the car, and he didn't be polite to the salesman, and walked directly to the second row and sat down.

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

The sales nodded, and said to him please wait, and when the sales came back again, in addition to the bag he was carrying, he also carried a pair of flat shoes in his hands.

After getting into the car, I changed out of my high heels, got in the car, and drove out of the showroom, heading towards the location of the DMV.

The car went out of the car city, and after driving for a while, the young lady who was driving in front did not go straight to the vehicle management office.

Instead, he turned a very sensible turn on the road and drove onto a no-man's road.

The car stopped, put his heels back on, pulled a document out of his bag and handed it to him.

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

Saying that, he came from the driver's seat to the second row, and then the battle began, and the car also rose and fell with the height of the car.

That is, if there is no one nearby, if anyone is bound to see a pair of long legs wearing high heels appear in the car window.

At the end of the battle, the sales lady swallowed what was in her mouth, cleaned up all traces, put on her flat shoes again, and opened the window all the way to the DMV.

For him, this time it was just a fast food, no matter how delicious the food at home was, he would always get tired of eating it, and it would feel good to mix the taste once in a while.

The efficiency of the vehicle management office is very high, and it should be that the car city has taken a special path here.

After all the formalities were completed, he drove directly in the direction of home, and the surprised young lady 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 simply made a confession, and then drove home with confidence.

This Gao He is not bad to drive, and the interior is full of science and technology, worthy of being one of the three musketeers of the Internet, Ding Sanshi made things, always at the forefront of the times.

The car did not drive directly back to his new home, but drove directly into the summer town factory, which was specially built for himself.

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

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

Parking the car, he threw his whole body, all his clothes into the washing machine with drying,

After that, I went straight to the bathroom, took a simple shower, wore a suit of work clothes, came to the side of the car, and lifted the car that had just come out of the exhibition hall.

I didn't expect this car to leave the factory that its life would be so bumpy,

As soon as he was bought, he was used to start a war, and after the battle, he was not counted, and what was waiting for him would be dissected on the operating table.

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

When he was covered with oil, he threw down the tools in his hand, and swayed out of the factory in his work clothes, walking in the direction of home.

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

When she got home, Li Yun had already come back, and she had already prepared dinner, as usual, eating, watching dramas, and sleeping.

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

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

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

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

As time passed, half a month had passed since he went to Shuicheng to buy a car, and he and Liu Xiaodong had passed the hurdle safely due to their early confessions.

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

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

The principle of super graphene lithium-ion special battery is also very simple, that is, the use of lithium-ion can be between graphene and electrodes at high speed, a large number of shuttle movement characteristics, the development of a high energy density of new energy battery.

In Kyushu, there are two battery giants that can be ranked in the world, one of which is the Dening era, and the other is a battery manufacturer disguised as a car company.

The two of them belong to 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 are the most widely used types of lithium batteries in the world.

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

In addition, it is stronger than ternary lithium in terms of safety, and it has obvious advantages in bulging and ignition.

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 is low.

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

Instead, he chose a new material - graphene, and what is unique about this material?

It all starts with graphene, and the battery he has come up with after 30 years with the help of the eye of analysis can be said to be extremely perverted.

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

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

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

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

Graphene is a single-layer two-dimensional honeycomb structure material formed by the tight accumulation of carbon atoms, which is simply a network structure.

Because of the limiting thinness (only the thickness of a layer of atoms), 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 holes.

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

The cathode of ordinary batteries generally uses large single crystal ternary materials, so as to improve the thermal stability of the materials.

The graphene he uses is very different, thinking that graphene has unique physical properties.

It can realize the rapid heat dissipation generated by lithium ions during movement, which greatly improves the performance of the battery.

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, when preparing in large quantities, the cost is relatively low.

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

So the more holes in the motor material, the faster the process will be.

Many of these phenomena have been formed, and the battery is charging and discharging faster and faster.

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

At present, the lead-acid batteries used in e-bikes are very slow to charge, often taking several hours.

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

And the battery he made this time is 80~200 times faster than the ternary lithium battery he usually uses.

Outrageous? Outrageous, outrageous!

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

Dozens of times or hundreds of times the speed, taking the car as an example, it takes 20 minutes to charge his supercharger to 50%, and it takes 80 minutes to fully charge.

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

That is to say, in the least time, the battery can be charged to 80% in less than a minute, and the remaining 20% of the battery can be charged in the charge protection mode, which will not take more than three minutes.

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

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

Can you say that this battery is not outrageous? Invariant?

This is a proper black technology!
