Chapter 168: The future of lithium-ion batteries

At 5:30 PM, Xu Qingzhou walked out of the library and headed straight to the laboratory.

Just as he expected, everything was normal. After debugging the parameters, he performed variable control.

After Ren Xiaoling waved her hand and said "Goodbye, junior brother," only Xu Qingzhou was left in the large laboratory.

Letting the machine continue to run, he took out the draft paper from this period and began to calculate.

The advancement process of the Twin Prime Conjecture was still difficult.

Studying prime numbers first requires a deep understanding of the inherent laws and properties of natural numbers, but the distribution of prime numbers in natural numbers is extremely complex and irregular, which makes predicting and proving the existence of prime pairs extremely difficult.

During this period, he had verified several methods to prove the Twin Prime Conjecture, but finally found that only Zhang Yitang's was effective, and with the efforts of mathematicians, it had been fixed at 246.

This means that as long as one continues to use this method to change the constant from 246 to 2, the Twin Prime Conjecture is completely proven.

He scanned the data roughly, and there were no abnormalities.

Xu Qingzhou was looking at rental information online. He put down his phone and said, "A bit tired, going to lie down early." Kong Xianbo nodded, spread out the book, took out his notes, and seeing Old Xu resting, he inexplicably wanted to read for another half hour.

Zhai Ziqiang sighed secretly. He had really thought about comparing with Xu Qingzhou last semester, but it was long gone. Recognize reality, give up illusions.

He didn't stay any longer, closed the door, and returned to the dormitory.

Dormitory 101.

The lecture was about to start, and Xu Qingzhou and the others didn't stand, sitting in the front row.

Soon, Xu Zhengyang also came back humming a song.

From 246 to 2, it seems to be only one step away, but things are not that simple.

Xu Qingzhou planned to go to the activity center to listen to the lecture. This was a lecture on new energy—the future development direction of lithium-ion batteries.

If the Selberg parameter was changed to a more flexible polynomial function... Thinking of this, Xu Qingzhou picked up his pen and wrote on the draft paper.

Zhang Yitang's method was still a kind of sieve method. He first proved the Bombieri-Vinogradov theorem and obtained an improved GPY sieve method.

This old man should be Academician Dong Shengyang.

At 2:30 PM, let Ren Xiaoling watch the experiment.

Beside Gong Yunfei, the young man wearing glasses asked: "Who is this?"

Xu Qingzhou tapped his fingers lightly on the paper on the table, his eyes looking at the various complex formulas on the draft paper.

"Senior Brother Ge, hello." Xu Qingzhou smiled and shook hands with the other party.

Xu Qingzhou also saw the old acquaintance Gong Yunfei. Professor Zhao Shengwen had recently been doing things related to lithium-ion batteries and was likely quite familiar with Academician Dong Shengyang. It was normal to send someone over to do odd jobs.

After he finished showering and lay on the bed, the two people who went to the library came back.

Xu Qingzhou was still the first to return to the dormitory. Kong Xianbo and Zhai Ziqiang were mostly in the library, and Xu Zhengyang, this guy, disliked that playing games in the dormitory wasn't fun enough, so he went to an internet cafe to play with others.

Doing research might be like this: walking 99 steps before discovering that the remaining 1 step is more difficult than all the previous journeys combined.

Seeing Kong Xianbo start grinding again, Zhai Ziqiang originally intended to use the fire stick that had been gathering dust for most of the semester to sing a song, but he gave up and sat down silently to flip through the textbook.

The speaker was Academician Dong Shengyang from the Research Institute.

A flash of surprise flashed in the young man's eyes. This was the mathematical genius who solved the Cramér conjecture. He reached out: "I've heard a lot about you. I'm Professor Dong's student, Ge Zixin."

During these days, Xu Qingzhou and the other had selected a house and were discussing with the landlady to see the house on the weekend. "Old Xu, resting so early?" Kong Xianbo was surprised.

3 days passed in a flash.

Gong Yunfei also saw Xu Qingzhou and enthusiastically invited Xu Qingzhou to his side, "Xu Xu Shidi Xu."

This method, due to the existence of the "parity problem of sieve methods," was an essential obstacle.

Academician Dong Shengyang didn't have many fake procedures, greeted the students with a smile, and then began to enter the main content.

Kong Xianbo suddenly had a sense of crisis. Don't look at Old Xu's sloppy appearance, his strength was there. Once he started grinding, he would grind a lot of people to death.

The improved GPY sieve method hit a dead end again.

This feeling of constantly absorbing knowledge, always progressing, and narrowing the gap with Old Xu was fascinating.

10 minutes passed. Xu Qingzhou rubbed his temples, intending to go through all the manuscripts again to see if he could find any new ideas from the details.

Xu Qingzhou felt that this guy would definitely fail this semester.

Xu Qingzhou exhaled. In fact, his general idea for solving the Twin Prime Conjecture was already very clear.

The choice of λ was still the Selberg parameter corresponding to k+z dimensions.

When Xu Qingzhou arrived, the report hall was almost full. On the podium, an old man with graying temples and a washed-white shirt was looking down at the documents.

Xu Qingzhou stood up and stretched, put away the manuscripts, and turned off the instruments. Today, he had completed the data collection of laser pulse width and spatial walk-off amount according to the plan.

Although the sieve method proposed by Goldston and others was relatively fine, it was not flexible enough and had no room for maneuver to adjust errors.

"My junior brother, Xu Qingzhou." Gong Yunfei introduced with a smile.

Regarding whether the conjecture could be completely proven by continuously optimizing existing methods, the mathematical community generally believed that the possibility was minimal, and Zhang Yitang himself held the same view.

!.

"Is it possible to jump out of the GPY sieve framework of Zhang Yitang?"

"That's right." Xu Zhengyang nodded and said with emotion: "That's why I've been planning to play games hard during this period, to finish all the games this semester."

s=∑\frac{\sigma_{ext{before}} 11:00 PM.

Song Yao's period came again, and she didn't want to move much. Xu Qingzhou originally wanted to go see it himself, but was held back by Song Yao, saying they had to go together.

Using various sieve methods, Siegel zero estimation, L-functions, automorphic forms... combined with existing achievements, standing on the shoulders of predecessors to pick the fruits of truth.

Zhai Ziqiang looked up and asked: "Brother Yang, didn't you say you were going to be serious this semester?"

However, it was still damn difficult.

From the current development of lithium-ion batteries in Xia Nation to the difficulties encountered, and then to the future development direction, he predicted that the next period of time would be the world of lithium iron phosphate batteries and ternary batteries, which were basically expected to replace traditional lead-acid batteries.

This old academician's lecture was very interesting, simple and easy to understand, and there was no lack of urine points for more than two hours.

This kind of lecture was different from academic exchanges. It didn't involve too many technical details, but only described from a macro perspective, expounding the development trend of lithium-ion batteries.

Of course, this was enough for Xu Qingzhou. He had a rough understanding of the development of lithium-ion batteries in the next period of time, and now he had an overall framework.
