After Ge Zhongxing watched Bill's group leave, he returned to the laboratory in a hurry and came to the place where he put the notebook.

As we all know, the lead of the pencil is made of a mixture of graphite and clay in a certain proportion, and the B on the pencil represents the content of graphite, the larger the number in front, the higher the graphite content, on the contrary, the content of soil is relatively low.

After Ge Zhongxing recorded the "graphite" in the notebook, he rechecked the experimental equipment to make sure that there were no omissions or negligence, and then closed the door and left.

After collecting the graphite, he returned to the lab and placed the lithium-ion and graphite together under a high-powered microscope.

After turning on the power supply, he observed that the former quickly penetrated into the graphite after conducting electricity, and it seemed to be looking for something, and the process was very interesting.

When Bill and the others reappeared in the lab the next day, they found that the environment in the lab was the same as when they left yesterday.

On the other hand, Ge Zhongxing, his face was full of excitement, and his eyes were red staring at the microscope. I don't know, I thought he was watching something earth-shattering.

Bill rushed over with a brisk step, pulled away Ge Zhongxing with one hand, and said, "Ge, go and take a rest, I'll help you take a look." He stepped in to observe, and after a few seconds or so, his mouth was wide enough to fit a goose egg, and his face began to show excitement.

The selection of anode materials can be regarded as a breakthrough through experiments, but only that, there are countless ups and downs waiting for them ahead, such as cathode materials.

Ge Zhongxing slept in the laboratory for a while, and the moment he woke up, he was inspired: he had seen in a certain paper that graphite contained graphene, which has always been an illusion, so why bother to find the preparation process of graphene through experiments first.

Step by step, he approached Bill and suggested: "Now that the team is relatively large, we might as well divide it into two, and one group will continue to complete the further improvement of the negative electrode until it can be mass-produced." In another group, we want to stabilize graphene that cannot exist independently under the action of external forces, which is a system engineering, and then we go hand in hand to save time. ”

"Prepare hypothetical graphene, the graphite in the pencil can be cut with a blade, so can we cut the graphite very thin with a blade?" Bill said, biting his lip and falling into a reverie.

"Graphite is carbon, but when we were in school, we found it to be malleable and tough. The tougher the toughness, the less likely brittle fracture will occur and can therefore be cut into thin slices.

In each layer, three other carbon atoms are connected to each carbon atom in a covalent bond, arranged in a honeycomb pattern. One of the white men muttered to himself and memorized the book.

"Then try it with a knife first?" Bill said uncertainly.

He found a blade, cut it with the first knife, and found a problem: this thing was in the form of a sheet, and when he took it to the microscope, he found that it was composed of layers of honeycomb-like orderly arrangement of planar carbon atoms, and finally formed a crystal.

"No, if it's that simple, it will still exist in legends?" This is a method of preparation of materials that has not been discovered by the scientific community for hundreds of years.

How is it possible to get them easily.

"The fictional graphene in the literature is very thin, only 1/200,000 of the diameter of a human hair. ”

"Is it so thin? No wonder, we're still very early in our encounter, keep trying. ”

"I'll try my pencil font inside, it might be a little easier. ”

But how do you get the pencil font out?

Ge Zhongxing looked left and right, and there was, he found a piece of white paper and lightly scratched it with graphite, and it could be seen that a greasy black line was clearly left on the white paper.

He took the transparent tape not far away and carefully glued it to the black line, the black line faded, and the tape turned black.

He carefully took the tape to the microscope to observe, and was not frightened, what kind of thing was this, or was it a characteristic of graphite.

He continued to find a blank piece of adhesive tape, glued it to the original adhesive tape with graphite, and found that it still hadn't changed.

After repeating this and so on countless times until it was completely invisible to the naked eye, he pasted it countless more times to make observations, and finally on the ninety-ninth time, it found a change under the microscope.

He found that its thickness was only as small as a carbon atom, and it was only a two-dimensional plane, a free-form atomic crystal, and the whole was honeycomb-shaped.

Its arrangement and combination of carbon atoms is the same as that of graphite, and the carbon atoms exhibit this honeycomb shape in SP2 hybrid orbitals.

They also discovered a shocking thing, this new substance is hard, even higher than diamond, but when an external force is applied to it, the carbon atom faces bend, they do not need to be rearranged to adapt to the external force, and the structure remains stable all the time.

So far, they have only known so much about this new carbon atom, but they believe that with further research, more discoveries will be made.

Bill and Ge Zhongxing glanced at each other, and they both saw the exhaustion between each other's eyebrows, especially the latter, but they didn't have much rest all night.

Bill called in his colleagues and arranged for them to organize the test procedures and data collation.

As we all know, in the scientific community, don't think that you can sit back and relax if you make it yourself, you need to repeat the experimental procedure countless times, get the same data and conclusions, and then publish these results to the public under appropriate circumstances, only after the vast majority of people follow this experimental procedure to get basically the same steps, this is considered a result.

Of course, there are also others who can't do it according to the steps, and on the other hand, the data is fake, and all kinds of strange incidents emerge in endlessly.

After Pal sorted out the data, Best compared the sorted out data with the original data and found no problems, and then rechecked the steps to confirm that the records were detailed, and then handed over the information to Bill.

After Bill double-checked and found no problems, he took the information with him to Daniel's office, the head of verification, and asked him to re-verify the steps and data.

On the side of the Battery Research Institute, there is a clear rule that the patent application needs to be signed by Daniel, the verification supervisor, before proceeding.

Of course, just in case, Daniel is also the only middle-level manager who is under the 24-hour close protection of the man in black except for the company's top management.

After Bill handed it over, he returned to the office, called Ge Zhongxing and other colleagues, and came to the café leisurely.
