In the clean-free room, Su Yuanshan was wearing a dustproof suit and stood with Chen Jianguo, staring at every step of the etching machine.

"Come and have a look?" After the etching machine stopped, Chen Jianguo took out the silicon wafer and put it under a microscope: "It seems that I can't see clearly."

"Well, you need an electron microscope. Senior brother, thank you."

"Don't be polite, many nano-level experiments rely purely on luck." Chen Jianguo laughed and said, "I hope I'm lucky."

"I think so too - if it does, I'll send paper to add your name."

"Don't, I won't receive any reward without any merit. I don't know a single hair of you, so I can just open a machine and add a name." Chen Jianguo waved his hand and said, "Is there anything else? If it's okay, I will continue to do my job."

"Uh... it's gone."

Su Yuanshan put away the silicon wafer and turned around and walked into the laboratory next door.

Although he was patient, he was still a little scared by countless failures. When he happened to meet Chen Jianguo who returned to the Science and Technology Park to verify the data, he decided to change his luck and ask Chen Jianguo to help him do it.

Under the scanning tunneling microscope, the Hall device on the silicon wafer is prepared perfectly.

Su Yuanshan clenched his fists gently and began to conduct the Hall test.

"On August 8, 1994, at 21:15 pm. Experimentalist, Su Yuanshan."

"The graphene Hall trial begins."

"Sample number, 0071. Thickness is 3 atomic layer sizes."

“The ambient temperature is 27 degrees Celsius.”

"The experimental steps are as follows..."

“…”

"Experiment summary."

"I conducted Hall effect-related tests on graphene samples with a thickness of 3 atomic layers at room temperature."

"In the experiment, the electrode and graphene contact were good. The sample had a magnetic field intensity of 0.353    t by the Vanderbilt method. Different data were obtained through the Hall voltage at different current intensities, and the results were processed and analyzed."

"Get the Hall coefficient rh of graphene = 7.00×10-7    m3/c, carrier concentration n=10.52×1024/m3, Hall element product sensitivity kh    =6.87×102    m2/c."

"August 9, 1994, 2:15 am. The signature of the experimenter: Su Yuanshan."

...

When Su Yuanshan wrote the last stroke of his signature, he raised his head, and for a moment, and then the excitement in his heart quickly subsided.

"Why isn't as excited as I imagined? Is it because I don't expect it?" Su Yuanshan frowned and stared at the experimental report tightly. After a moment of silence, his lips curled up and he smiled mockly: "Sure enough, there is still no pleasure in cheating."

"But I'm not cheating, right? I'm just cheating when I tear it... The experiment was designed by me alone from beginning to end. Well, I probably don't have a sense of expectation... After all, this thing must be at the Nobel Prize level."

Su Yuanshan muttered to himself and began to do the finishing work.

When I walked out of the laboratory, it was already 2:30 am.

Even the night owls were sleeping at this time, and the entire Yuanxin Technology Park was silent.

Walking by the lake, a scolding suddenly came from the darkness.

"Who is there? Don't move!"

Immediately, a beam of light from a flashlight shot towards Su Yuanshan's face.

"Master Shan?" The flashlight beam moved down rapidly.

"Well, I've done an experiment and caused trouble for you." Su Yuanshan put down his eyes-covering hands, adapted for a while and recognized the two security guards: "Thank you for your hard work."

"We work night shifts, so it's not hard, you are the hard work of Mr. Shan." The security guard said embarrassedly: "Then we will continue patrolling."

Su Yuanshan continued to move forward and walked through the peach forest. Before he could enter the plum garden, he heard a low quarrel, including a female voice.

And night owls?

Su Yuanshan quickly coughed and walked into the plum tree forest with a few steps.

Under the street light, Li Xiao and Cheng Peng were holding a report and quarreling in a low voice.

"Sister Xiao?"

"Small Hill?"

"Mr. Shan?"

Seeing the two of them, Su Yuanshan couldn't laugh and cry: "What are you doing if you don't sleep in the middle of the night? Are you in love?"

"Talk a fool..." Li Xiao walked to Su Yuanshan in two steps: "What about you who have been doing the experiment until now?"

"Uh, so too, I forgot the time by accident." Su Yuanshan said, looking down at Li Xiao. This girl has been in Yuanxin for a year. Except for occasionally having an appointment to take her own car to call the department on weekends, she stayed in the laboratory almost all the time.

So a good girl is as flirted with a yellow-faced woman every day.

"By the way, how many batteries do you know?" Li Xiao didn't care what time it was now, so she pulled Su Yuanshan and asked.

"I understand Yidiandian, what's wrong?"

"Okay, I had a little disagreement with Senior Brother Cheng... Senior Brother Cheng believes that the positive electrode material can be more radical. I think lithium iron phosphate is already very good now. First, we have technical advantages and can launch the market quickly. Second, lithium iron phosphate is relatively safer." Li Xiao pulled Su Yuanshan and Chong Cheng Peng frowned: "A accident has occurred on Senior Brother Cheng."

Cheng Peng also came over at this time and laughed: "Little girl, please stop reporting."

"That's right, Mr. Shan."

Cheng Peng pondered for a few seconds. Now he is much more calm than when he met Su Yuanshan. He is really not frigid. His long literary hair has been cut short, but his face is full of stubble.

"I originally planned to have a clear division of labor with Li Xiao's two teams. She is responsible for the materials, and I am responsible for the overall architecture technology, so it is convenient for the launch of new products to enter the market as soon as possible."

Su Yuanshan nodded.

In fact, this is also his idea. After getting Sony's lithium battery technology last year, it was actually not used for a few months. Cheng Peng mastered the complete set of technology. In theory, the Yuanxin can produce lithium batteries.

But in fact... Now, the pricing of lithium batteries, whether it is a production line, brand or raw material is in Sony's hands.

This leads to a result. If Yuanxin uses Sony's solution to produce lithium batteries compatible with Sony, its competitiveness will definitely be inferior to Sony. If Sony wants Sony to get Yuanxin's solution, it will only be available in the local area and in the west.

So later Cheng Peng turned to Li Xiao and tried to get a safe iron-lithium polymer battery as soon as possible.

Moreover, Cheng Peng and Li Xiao both believe that once the iron lithium polymer battery appears, it will definitely be a disaster for nickel-chromium batteries now.

But after the cooperation, Cheng Peng had new ideas.

As Li Xiao said, he believes that the positive electrode material can be more radical, such as using ternary compounds.

"We made some attempts and found that if nickel salt, cobalt salt and manganese salt are used as raw materials to form new compounds as the positive electrode, the reaction activity will be greatly increased."

"Of course, increasing liveliness means an increase in the risk factor." Cheng Peng smiled and said, "However, these can be solved by designing various safety solutions."

Su Yuanshan nodded and looked at Cheng Peng in surprise.

This guy didn't even ask for a prompt to think of the three-yuan materials?
