Scholar’s Advanced Technological System

Frick Chemical Lab's hardware level is truly the best in the United States, and Princeton, who is rich and generous, not only has to spend money on professors, but also has no ambiguity about the investment in instruments.

Connie smiled as she moved the latest MACCOR high-precision battery testing system.

“The best battery testing system in the entire Flickr chemistry lab is this guy, and I borrowed it for you! ”

Ark: “Actually, there's no need for such a good battery testing system...”

Connie explained, "But you said that investing in the instrument is better than spending the budget on samples consumed in duplicate experiments. ”

Staring at Connie, the ark suddenly felt that the boy was not as thick as he looked.

The money was on his account when he bought the machine.

If it had been before, the ark would have been heartbroken for a while.

But now...

Well, waste is shameful, he's still a little heartbroken.

But it doesn't hurt that much.

Put the instrument thing aside for now, and the ark seriously asks: “Do you do battery samples? ”

Connie immediately said, "No problem, it's easy! ”

The Ark thought about it and made the order: "You are in charge of samples 11 and 14, and I am in charge of samples 15 and 23. Mix hollow carbon sphere powder with single sulfur according to a mass fraction of 30%, 20%, and 10%, make a cathode material, and then assemble lithium electricity. What do you know? ”

Connie's right up her chest: “Of course! ”

Anode materials have nothing to say, because the synthesis process is simple, and now the combination of modified PDMS films and copper lithium chips is not only standard for industry, but also for major materials research institutes.

As for the cathode material, it takes a little bit of refreshment.

Not just hollow carbon balls, all carbon nanomaterials have similar problems.

Simple mechanical stirring and grinding can only allow the hollow carbon sphere polymer to mix macroscopically with the matrix powder, which is powerless for dispersion of the polymer itself.

Before the hollow carbon sphere is mixed with monosomal sulfur using a ball grinding method, it is also dispersed in ethanol by the addition of surfactants such as ethyl polycarbamate before mixing with monosomal sulfur.

As for the remaining steps, there is no particular difference from the lithium experiments that were performed on the original ark.

Assemble the batteries in the glove box and attach the battery test system to confirm the performance of these materials in the electrodes through a large number of charging and discharging tests.

None of these jobs have any skills.

In fact, the study of materials itself is not very skillful.

The current research and development of new materials is based mainly on the researcher's “scientific intuition” and a large number of repeated "experiments”, using limited conditions to discover a viable method. It would be a pretty good bull to build a theory that would be applied within a limited range once again.

Although mathematical methods can reduce the workload of experiments, experiments are still essential…

……

Remember the last liver explosion, or this time last year.

In order to complete the final step in resolving Gothenbach's assumptions, the Ark locked itself in a world of less than twenty square feet, completely immersed in a maze of numbers, searching for the ultimate way out.

Compared to what it felt like back then, it was like a little witch seeing a big witch.

This feeling of prolonged disobedience is truly memorable.

Almost a week has passed since the first experiment began.

During this time, apart from not sleeping in the lab, the ship was basically soaked in the lab for the rest of its time.

Plus, two days ago, Yang Xu, who directed the experiment at the Jinling Institute of Computing Materials, tabulated the effect of hollow carbon sphere specific surface area and pore size on sulfur load, mass score of polysulfur compounds in electrolytes, etc., and sent it to his mailbox.

In order not to delay work there, he needed to build a mathematical model based on the data as soon as possible and then develop a further experimental plan.

Things seem to be all stacked together.

Rubbing his sour brow heart, the ark threw the ballpoint pen away and looked at Connie, who was observing the sample, and asked.

“How is sample number 15? ”

Against the dark circle, Connie's expression, guarded by the scanning mirror, shook his head somewhat bitterly, "The last group was also completely obsolete, with almost all the sulfur monomers deposited on the surface of the carbon material. You can come and take a look, it looks spectacular...”

The ark sighed softly: "Take the sample to the scanning mirror and take care of it… I've seen enough. ”

Too bad.

If that were the case, the three sets of samples numbered 11, 14 and 15 would have been almost completely neutralized.

For the results of such a tragic experiment, the ship even began to wonder whether its theory was in question.

Can hollow carbon nanospheres with a surface area of [2326m2g-1, 3762m2g-1] and a diameter of [60nm-70nm] really inhibit the diffusion of polysulfur compounds?

Yet this is the last thing he wants to doubt.

Because after that, he counted again and again, and he got the same result.

If this theory is really wrong, then he has to face a tough choice.

To pretend not to know, to continue to pit the industry out of conscience. Still a respectful scholar, discovered errors proactively corrected, honestly proactively contacted the editorial department of Shui Wood University Journal to withdraw the draft...

In the former case, the feasibility is very high. Even if it is proven wrong in the future, it can be "honest mistake” and no one will make it difficult for him. But thinking about the social resources that are wasted...

Wait a minute!

All of a sudden, the ark was a spiritual and returned to God.

I haven't even finished this experiment yet, so I'm starting to think about the aftermath.

Where are we going?

Squeezing his fist, the ark took a deep breath and calmed down, looking at Connie and continuing to ask.

“What about sample 23? ”

“Let me see… 10% and 30% of the groups have been ruined since the 200th transfer, 20% of the groups… Incredible, it's all 500 revolutions and still struggling. ”

Struggle is an interesting word to use.

It would appear that his assistant had no hope whatsoever of the experiment.

However, in the case of an ark, it is completely different.

As if he had caught the last straw, he restrained his exciting tone and asked: “What about the volume change of the anode material? ”

Looking inside through the transparent part of the battery case for half a day, Connie stunned slightly and came up with an ambiguous answer: “Nothing seems to have changed. ”

The ark restrained the impulse to explode: “Don't use visual inspection, open it with a cursor caliper! I want an accurate answer! ”

“I know, I was just kidding...” I dismantled the battery and Connie carefully processed the cathode material inside and measured its width change with a cursor caliper.

The volumetric expansion effects of carbon sulfur composites, once they occur, can be clearly observed even at macroscopic scales.

After one test, Connie recorded the data on the experimental report and suddenly stunned.

Then he tested another group.

Another group…

The ark frowned slightly as he watched Connie dawdle there.

“Failed? ”

“No...” Connie shook his head, swallowed his mouth and spat, "It's hard to believe how good it turned out...”

“Carry out the electrolyte chemical composition assay now!” Standing up from the office chair, the momentum on the ark is unprecedented, "move fast! ”
