Chapter 304: Hollow Carbon Balls Good

Professor Sun Hongbing's voice had just fallen, and a pair of sights looked towards the ark.

Especially from corporate representatives and engineers, one eye at a time is dazzling.

And the ark at the center of sight, at this moment holding a mineral water bottle, a face question mark.

Since when do I have bamboo in my chest?

Why didn't I know?

In fact, the reason he did not participate in the discussion, or even showed indifference to the performance of the seminar, was not that he had an idea in mind, but that he did not know what to say.

Unlike most cattle in material science, the mathematician's rigour dictates that he has to write a draft before bragging. Professor Sun suddenly kicked the ball to his feet, and it was a little too soon for him.

But at this point, the ark suddenly moved, dropped the mineral water bottle in his hand, held the microphone up, and cleared his voice.

“… According to what I heard at the MRS meeting, the shuttle effect is the biggest difficulty constraining this technology for the lithium-sulfur battery block. Academia has not come to a unified conclusion on how to solve this problem. ”

“My personal view is that both ideas are good, solving them from a cathode material is a good idea, and using solid state electrolytes as an entry point is also good. We can go along two lines, both hands to grab, both hands to hard. ”

The ark that said that couldn't help but give itself 32 compliments for wisdom.

As to the inappropriateness of using the last sentence here, he was also not aware that he had been wandering around the pass line in his own political class and was too lazy to care.

The answer to this cardinal oil is the least likely offender.

The bosses are tearing up the money for research, but it's better if he pays for the experiment himself or doesn't mix it up.

Too much has been said, it will be responsible in the future.

However, Professor Sun Hong Bin, obviously does not intend to let this tree go.

Only the old man smiled and continued to ask.

“Professor Lu is right, but that is true, but there has to be a focus if we are to concentrate our limited resources to achieve a great cause. From your point of view, which option do you think is more promising? ”

The professor at Shui Wood University is also an expert.

Mostly he did the surface polymer of the cathode material, and seeing as he solved the lithium-crystal problem with the modified PDMS membrane, he bet he liked the direction of the polymer as much as he did, and pushed him out decisively as a gun.

But to be honest, although the ark solved the lithium-crystal problem with a modified PDMS film, he did not prefer the same method of adding surface polymer material to the cathode material for the shuttle effect characteristic of lithium-sulfur batteries.

As for the reason, he couldn't say one, so maybe it's just an intuition.

Thinking about it, the ark not only had a little bit of a cry.

All of a sudden, the "white school” scene always feels guilty of choosing anyone.

After all, in the lithium electricity section, he is not a little transparent, in order to take Lu Lao's opinion seriously, he is also conscious. The ticket in your hand, I fear, can be two or even three.

He knew it would come to this, and he inferred that something was not coming.

The ark sighed.

There's no other way.

In a rigorous manner, he did not want to show up with unperfected research results, but if he continued to push back, he would have some correction.

And if he is used by someone with a heart, saying that he is “not hard” on the national project, enjoying policy support but touching the fish again, it is not good to spread the influence.

Reflecting for a moment, he said.

“If I may, I personally prefer the direction of the hollow carbon ball. ”

As soon as it came out, many people were stunned.

Professor Sun, in particular, obviously did not anticipate the choice of an ark.

Professors and scholars in the conference room have different expressions, some of whom are overjoyed, some of whom are indifferent and some of whom are disrespectful. The delegates on the side of the company were bright eyed and looked forward to the continuation of the canoe.

As for Lu Lao, it is a valued expression.

“May I ask why? ”

“Sure,” the ark paused for a moment, continuing, "the hollow carbon sphere has a large internal cavity, suitable as a carbon matrix with high negative sulfur levels. At the same time, the external porous housing structure can effectively inhibit the diffusion of polysulfur ions. Besides, it has its own structural stability and good electrical conductivity, which I personally like. ”

After the sound of the ark fell, Wu Yancheng from Yanda asked: “I have a question. ”

The ark made a gesture: “Go ahead, Master Wu. ”

"Hollow carbon balls are a very new concept, but new concepts are often hidden dangers. Technically, when a lithium ion is embedded, it causes the material to expand volumetrically, which can lead to alloy dusting as the charging and discharging cycle proceeds. Again, the idea is that this technology is difficult to apply to industrial production. ”

Ark: “Reducing the particle size of the active substance can reduce the degree of micronization, which is technically achievable. ”

Wu Yanchuan glanced sharply and continued to ask: “What about the problem of bulge? Have you considered volumetric energy density? ”

The Wu Academician is also an interesting person, taking a "chi” tactic on directions other than the direction of solid electrolytes, but avoiding talking about his views and giving people a chance to turn back. Probably intend to wait until the end of the workshop to make a hammer.

However, this is one of the formal means.

Science and technology are objective, good or not, but subjective.

There are not so many non-black and white conclusions about technical problems, and academic exchanges have themselves developed in a mutually reinforcing fashion since the advent of academic conferences.

And cheerful as Ben Shenko, a thousand mouths are all an argument, that is not to call a meeting anymore, and nothing can be discussed at all.

In response to Wu Academician's question, the Ark continued: “The problem of volume expansion of the active ingredient in theory can be compensated by the construction of a 'buffer skeleton' by means of phases that can be alloyed with lithium metal and dispersed into inactive phases that are not alloyed with lithium metal. ”

Wu Yancheng had nothing to say for the time being, but another person stood up again.

Professor Wang, who had previously been arguing with Wu Yuanshi about the feasibility of carbon sulfur composites, asked in a sceptical tone: “How sure are you? ”

As soon as I heard that, Ark Zhou stopped to like it.

Wu Yanshui, let me forget it. After all, it's not one direction. You're a carbon sulfur composite. I'm a wool maker! Everybody's going in the same direction, or are you just going to stop thinking about "bulge”?

With regard to Professor Wang's question, the Ark is serious and serious.

“Scientific research is not about infrastructure. Don't expect money to be thrown in and it will succeed. You ask me how sure I am, even if I tell you 1% or 99%, what's the use other than opening a river? ”

This sentence brings Professor Wang to choking blush, unable to speak.

Lao Lu coughed softly and played the round field: “Everyone's original intentions are good. Our discussions are still academic and focused on qi. ”

At this time, Professor Sun, who had previously encouraged the Ark to speak, seemed to have seen the Ark's answer fail to meet his expectations and got up again to speak.

“I'll say it again. ”

Mr. Wang smiled and said: “Professor Wang also asked out of concern. In fact, I am also a little confused about the direction of the hollow carbon ball. However, I heard that Professor Lu is an expert in the field of computational materials. I think he must have unique insights. I wonder if it would be convenient to answer some of these Xuan machines for us? ”

When Professor Sun asked this question, he didn't really think he could answer the question from a mathematical point of view. He was just afraid that the kid would open his mouth at the meeting. It would be fine to ignore a few professors, even if he ignored Lu Lao who was sitting there.

After all, solve the shuttle effect of lithium-sulfur batteries.

That's naturally the surface polymer material I'm working on.

What he did not expect, however, was that his question was in the arms of the Ark.

I was embarrassed to see the Ark boat and looked at Lu Lao and asked.

“Well, is there a blackboard? ”
