Negative Electrode Material Chapter 16

Technology Open Day

Chapter 16 Technology Open Day

Since Lin Yi started WeChat, he has only posted a dozen Moments in total, and half of them are forwarding content from the college’s official account.The only content I actually wrote was holiday greetings and the same thing as today: Teacher’s Day thanks.

The photo in the circle of friends shows a bouquet of carnations, randomly inserted into an empty glass jar found somewhere, and the background is his desk filled with books and papers.The photo is not color corrected.

Lin Yi had actually thought about such a seemingly indifferent circle of friends for a long time.

These flowers were not given by students, but distributed uniformly by the school. Each teacher had a bouquet.His real gifts were far more than that: his desk was piled with exquisitely packaged chocolates, small cakes, stuffed animals, and even a few letters full of love.

Posting these will inevitably lead to some comments that are neither salty nor mild: “Teacher Lin is indeed the most popular teacher among students”, “How dare you post this because you have never seen the world”, “Who are you showing this to?”.Lin Yi doesn’t have a bad brain and won’t look for this on his own.

But he also felt that it would be too cold to not respond at all to the students’ sincere and warm emotions.——What’s more, he and some students have almost lived together in the same room recently. Even when adjusting data late at night, the students ordered midnight snacks and never forgot his share.

After much deliberation, he picked out the most “neutral” bouquet of flowers.Better than nothing.

After clicking “Publish”, he stared at the phone screen for a few seconds, still not completely relaxed.

Almost instantly, several red dots popped up on the screen one after another.Lin Yi clicked in and saw the praise from Li □□ and Gao Huan.

He heard that the young master could not come to the Technology Open Day because he was in Europe for the past two days.I subconsciously calculated the time difference in my mind – it’s early morning over there.

Mr. Gao stayed up in Europe, forgetting to eat and sleep, supervising the open house remotely?Or are you just having a sleepless night and just scrolling through your Moments with nothing to do?

Lin Yi stared at the name, his fingertips hovering on the screen for a few seconds, and finally locked the screen silently.

September 10th, Technology Open Day.

The International Hotel and Conference Center next to the National University has a high hall and is surrounded by floor-to-ceiling windows. The afternoon light comes in, making the hanging banner of “New Energy Technology·Industry-Academic-Research Open Day” particularly conspicuous.

Microphones and folders with school emblems were neatly placed on the long table in the front row. The guests in the audience were divided into three groups: corporate representatives in suits, reporters holding cameras and recorders in their hands, and several professors from our school and brother universities.The students sat in the last few rows, looking excited and nervous.As the main investors, Wang Yuan and Li □□ sat in the first row of exclusive seats.Wang Yuan’s face was expressionless, while Li’s face was shiny, half tense and half tired.

Lin Yi stood on the podium, with the first page of the PPT displayed on the big screen behind him.His voice was not high, but clear and steady:

“Our laboratory mainly studies negative electrode materials for solid-state batteries. This is our latest synthesized silicon-based compound negative electrode. During the lithiation/delithiation process, it can alleviate volume expansion through reversible nanophase transformation, allowing the electrode to maintain more than 80% of its capacity after three thousand cycles.”

There was a low discussion in the audience.A researcher from a foreign company sitting in the first row raised his hand and asked: “Dr. Lin, are there any obstacles in the large-scale synthesis of this compound negative electrode? In particular, will the ratio control of iron and phosphorus lead to the formation of secondary phases?”

This question attracted the attention of many audience members, and there was like a tight string in the air.

Lin Yi paused for a moment and looked calm: “What you said is indeed the key. We also encountered the problem of accessory phase segregation in the previous experiments. Later, we controlled the reaction path through dual-temperature zone gradient heat treatment to obtain a relatively stable crystal structure.”

Lin Yi then showed the three sample curves with different drying times. His voice was low but calm: “The complexity of the process is also a challenge. The seventy-two-hour drying process is the key to obtaining a stable interface under current conditions. If the cycle is shortened, the generation of secondary phases and interface cracks will increase sharply. We are now jointly developing a rapid drying process with the industry. The goal is to compress the time to less than twenty-four hours, but maintain the same stability.”

When it came to question time, a company representative in the audience spoke first: “You mentioned that the drying cycle takes seventy-two hours. For the factory, this is an unbearable production cost. How do you respond?”

Lin Yi held the laser pointer in his hand and was silent for a moment before speaking: “This is a fair question. We cannot deny that there is a gap between the laboratory and industrialization. Our idea is to first prove the feasibility of the material mechanism and then promote the improvement of the process route. Without the former, the latter is impossible to talk about.”

Later, a professor from a brother university raised his hand and said with a thorn in his side: “The data of Group C fluctuates greatly. I suspect that the system itself is uncontrollable. Why do you still display it here?”

This question made the atmosphere at the scene even lower.

Lin Yi’s palms were sweating, and countless possible answers flashed through his mind: Want to explain the experimental conditions?To admit that the results are limited?Or are you just saying nice things along the lines of investors?

In the end, he just straightened up and looked at the audience, his voice cold but calm: “Science and quick success are opposites. What we show is not the product, but the evidence that the problems have been solved one by one.”

Just when the air was about to solidify, a representative from the company wearing a badge said with a smile: “Professor Lin said it well. Scientific accumulation takes time, which is why we are willing to support it for a long time.”

Applause broke out, sporadic at first, and then gradually into a continuous wave.

Lin Yi noticed that the representative who supported him glanced at the row of investors when he sat down.Wang Yuan was sitting there, tapping his fingertips on the table with a cold expression.Li □□ had a professional smile on his face and kept applauding.

Lin Yi knew in his heart that these “voices of support” were pre-arranged by someone.If the scene is cold for too long, someone has to light a fire; if the fire is too hot, someone has to put out the fire.Everything can be controlled, and everything is paid for.

The host took over the words at the right time: “Transparent data is more valuable than empty promises. Thank you Professor Lin! Next, please move to the exhibition board area. The students have prepared detailed experimental records. Close communication is welcome.”

Applause rang out again, reporters rushed forward, and students stepped forward with nervous and proud smiles.

Lin Yi walked off the podium, his back straight and his steps steady, but his heart felt cold.

Li □□ came forward, as briskly as if the smell of gunpowder just now was just an illusion: “Thank you, Teacher Lin! There are many voices from the outside world, but everyone understands that this is the norm in scientific research.”

Lin Yi nodded and replied calmly: “Yes.”

Wang Yuan also came over, saying “Thank you for your hard work” on the surface, but his expression was meaningful.

After that, the two left one after another.

Lin Yi stood there, looking at the bustling crowd in the venue, but feeling more like he was alone in his heart.The sky was getting dark outside the floor-to-ceiling window, and the lights were reflected on the glass, reflecting his face that was almost transparent.
