Chapter 679: Was the show-off predicted?

July, the summer heat is at its peak.

Besides the heat, it's just busyness.

At the beginning of the month, Xu Qingzhou celebrated his 24th birthday, went shopping with Song Yao, and had a good meal.

The dendrite group is doing the final finishing work, conducting iterative experiments, perfecting technologies like TiON-TiO nanocoatings and magnetron sputtering gradient doping, intending to improve the sample's performance.

Xu Qingzhou went into seclusion at home for 2 days, analyzing various data. He had no ideas on his side, and the shuttle effect group's experiments also fell into a bottleneck.

The two materials they are currently working on, carbon nanotube composite aerogel and FeCoNi-S high-entropy sulfide, did not improve the effect as expected.

This made them quite hurt.

During the same period of experiments, the lithium dendrite group was already finishing up, while they didn't know when they would be able to produce results.

Thus, Xu Qingzhou, who had just finished his birthday, soaked in the lab for three days.

Finally, following Zheng Xu and the others, he solved the problem of cracks always appearing in the SEI film after the above two materials.

Song Yao was not to be outdone. On Lingdian Technology's side, there were a lot of things. Just counting the lithium dendrite aspect, they could apply for more than a dozen patents.

This was just the beginning.

From material composition and structure, that is, nitrogen-doped TiON lattice structure design, bionic multi-level pore coating, etc., to preparation processes, including realizing nitrogen atom lattice embedding, magnetron sputtering gradient doping technology, etc., and finally to equipment and testing, the independently designed in-situ dendrite monitoring coating integration system...

Apply for basic patents first, cover core structures, initially form technical barriers, and then build peripheral patents.

It sounds simple, but the engineering volume is not small when you really do it.

The dendrite group advanced in an orderly manner, and Xu Qingzhou took time to perfect the anion migration model for the shuttle effect group.

He finally had time to pull the shuttle effect group's experiments from beginning to end, logically retracing the experimental steps, which could connect scattered operations into structured memory, helping to deepen thinking.

July 6th, Monday.

Office, Xu Qingzhou frowned, throwing the experimental report to the side.

He spent two days reviewing all the experiments from last September to now, but unfortunately, he didn't get any useful information.

"My head hurts from looking at it."

Xu Qingzhou sipped coffee to refresh himself. After looking at the data for two consecutive days, he was a bit numb.

"No ideas at all. All materials that should be tested have been tested. Is it really a bottleneck?"

He slid the mouse, and his gaze fell on the project file.

"Actually... I haven't finished reading them all."

Xu Qingzhou thought for a while and opened one of the files, which contained abandoned plans.

Two hours passed, and the sky was already dark.

"Hoo~"

"Finally found something different. This nitrogen/boron co-doped carbon nanotube seems to have something going for it."

Xu Qingzhou's gaze fell on the abandoned plan.

Zheng Xu's group tested three materials at that time, and this nitrogen/boron doped carbon nanotube was abandoned due to insufficient synergy between conductivity and catalytic activity.

"But from the experiments over the past few months, it has an advantage that other materials don't have: strong chemical adsorption, forming strong polar sites, which can chemically anchor LiPSs."

"Perhaps, we can start from this."

Xu Qingzhou turned the signature pen in his hand and did it immediately. He took a brand-new manuscript from the corner of the table.

Thursday.

After finishing the last class of this semester, Xu Qingzhou rarely had time and ran to Professor Gu Zhizhong's side to drink tea.

"Yo, rare guest. You kid haven't been to my side for a long time."

Only the old man Gu was in the office; Meng Bin took two junior brothers and sisters to visit Shuda.

"Been busy these days."

Xu Qingzhou didn't stand on ceremony with Gu Zhizhong and sat down with a smile.

Usually, when he had time after class, he would go to sit with Gu Zhizhong or Chu Jiangfeng.

Chu Jiangfeng, unlike Gu Zhizhong, was still teaching undergraduates and rarely stayed in the office. At 50 or 60 years old, he flew all over the world, so he went to Gu Zhizhong's side much more frequently. ===== CHAPTER 680 =====
