Professor Krell is not wrong in his speculation.

When he hurried back to the lab, the sample placed on the field emission scanning electron microscope did not smoke, did not explode, and everything was surprisingly fine.

Through several sets of SEM images, it can be clearly observed that lithium ions are gradually deposited on the electrodes protected by the modified PDMS film, like a beautiful layer of silvery tundra.

But instead of growing savagely and developing deadly dendrites like in other lithium batteries, this "tundra" lies quietly underneath the modified PDMS film, gently undulating over time.

Nucleation did not occur, or it did, but it was channeled.

If nothing else, this state will be maintained until the entire charging process is complete.

There is no doubt that they succeeded in reverting the experiment.

"Unbelievable ......"

Standing next to the computer, looking at the images continuously generated by the field emission scanning electron microscope next to him, Professor Krell said three words in disbelief, still unable to vent the shock in his heart.

Even though the same image has been posted in Nature Chemistry, it is far from being as intuitive as seeing it in person.

The Columbia TV reporter standing behind him looked confused, not understanding what the researchers were happy about.

Even if he stood here and witnessed the great moment, he couldn't see any mystery in these SEM charts.

Out of confusion, he spoke.

"Professor?"

Professor Krell came back to his senses and looked at the reporter with a pleasant face.

"What's the matter?"

He's in a good mood right now, very, very happy.

If the lithium dendrites problem is solved, his lab will directly benefit. I believe that it will not be long before his laboratory can get tens of millions or even hundreds of millions of dollars in investment after at most an MRS meeting.

What kind of posture did the industry use to throw away the lithium battery at the beginning, and now what kind of posture must be used to invite it back.

The reporter swallowed and spat, and asked, "How is the situation?" ”

Professor Krell looked at him with an affirmative look: "I can now tell you responsibly that it has succeeded. ”

Perhaps sensing that his statement wasn't shocking enough, he paused for a moment and continued.

"Maybe half a year, maybe a year, you can use a smart phone that is on standby for a week. In a few years, you will be able to see Truss with a range of thousands of kilometers outside of PPT...... Believe me, my bragging is definitely more reliable than yours. ”

This may be an exaggeration, but it is definitely not out of reality.

At present, lithium-ion batteries are mainly based on graphite anode, which can be calculated through the product LiC6, and the theoretical specific capacity of graphite is 372mAh/g, regardless of the cost, this number can be turned into 747mAh/g through graphene technology in the laboratory.

As for the theoretical specific capacity of lithium?

It is 3860mAh/g.

Although many things can't be directly applied to addition and subtraction, you can still intuitively feel it from the numbers, and the four-digit crushing of three-digit numbers.

And in terms of cost, lithium metal and polydimethylsiloxane are completely acceptable.

[Congratulations to the host for completing the reward mission!] 】

[The completion of the task is as follows: solve the lithium dendrite problem.] 】

[Final evaluation of the mission: None (no evaluation for the reward mission)]

[Reward: 70,000 materials science experience, 10,000 biochemistry experience, wreckage.] 】

A pure white system space.

Looking at the experience tips poked out on the holographic panel, the corners of Lu Zhou's mouth couldn't help but turn up a smile.

It is worthy of the technology of advanced civilization, and even a small electrode brings considerable experience.

These experiences certainly can't make a splash in mathematics, but his materials science and biochemistry are both LV1, and throwing them in these two disciplines directly makes him feel like riding a rocket.

This bonus mission is probably the most enjoyable one he's ever done.

"System, open the Properties panel!"

The white light flashed, and the data panel quickly appeared in front of Lu Zhou.

Materials science has been upgraded two levels in a row, to LV3, and is now at the same level as physics. Biochemistry has also been upgraded by one level and is now LV2.

However, although Lu Zhou has read a lot of books and literature in this area under the guidance of the system task, after all, he is not a person who studies this field full-time, and he does not feel the improvement of his thinking ability in that discipline for the time being.

At least not as intuitive as the math made it feel to him.

Perhaps this also has something to do with the fact that the two disciplines don't rely so much on "inspiration".

After closing the attribute panel, Lu Zhou looked at the inventory next to him.

Lying in the inventory, Remnant 2 is a black cube, about the size of a third-order Rubik's Cube, and from the appearance alone, it gives people a very fascinating feeling.

Unlike the wreckage No. 1, which could be seen at a glance to be a battery, for this unknown thing, Lu Zhou took it out of the inventory and looked at it for a long time, still confused, not knowing what it was used for.

Toys of high civilization?

Not quite like that.

As for weapons, not to mention.

The most fascinating thing is that there are no scratches on the surface of this cube, and Lu Zhou can't even see what is wrong with this thing, so it was judged by the system to be "wreckage" and sent to him.

Putting aside this poorly researched thing for the time being, Lu Zhou continued to look at the taskbar.

The bonus mission is complete.

Then it's time to do the "multiple-choice questions".

Hopefully, some interesting tasks will come out.

Taking a deep breath, Lu Zhou stretched out his finger and clicked on it.

【

Task 1: Keep improving

Note: The technology of lithium anode materials is not only modified polydimethylsiloxane films, but also the carbon nanomaterial balls that flatten the cross-sectional folds.

Requirements: Successfully prepare the product in the laboratory and publish a paper.

Reward: 50,000 materials science experience. 500 points. Chance to draw (85% garbage, 9% samples, 6% drawings)

】

【

Task 2: Even great work cannot be done without the support of an economic foundation

Description: The lab is like a black hole, and as the project leader, you never know how much money you will spend until the project is completed. You may be confident in your work, but your partner may not be as confident as you. Rather than being controlled by others, it is better to raise your own funds.

Requirements: From the beginning of the task collection to the end of the year (12/31/16), calculate the host's personal asset blessing.

Reward: 1-??? Free experience ($1000 = 1 free experience). 500 points. Chance to draw (80% Junk, 10% Special, 7% Sample, 3% Drawing).

】

【

Task 3: Research is not a one-person task

Description: The value of a top researcher lies not only in how much research he has completed, but also in how many talents he has cultivated. Many scholars may have passed away, but the teachings they left behind are still influencing and changing the future.

Requirements: Train at least one student and complete a graduation thesis.

Reward: 1-??? Discipline experience (the final experience is comprehensively evaluated by the academic value of the paper and student participation), with 500 points. Chance to draw (50% garbage, 30% samples, 20% drawings)

】

Staring at these three tasks, Lu Zhou thought for a long time.

Flattening the cross-sectional folds of carbon nanomaterial pellets is important, but not decisive.

For the advanced civilization that created the "wreckage", those folds are unacceptable flaws, but for any battery manufacturer on the planet, this flaw can be ignored.

After all, compared with modified polydimethylsiloxane films, the latter determines the vitality of the product, and the former only determines the market competitiveness of the product.

The superiority of the lithium anode material itself has already exploded the graphite anode.

And the most important thing is that those hollow carbon nanospheres, with the current conditions of Lu Zhou, even if they know the molecular structure and three-dimensional conceptual images, there is no way to replicate them.

For these two reasons, task 1 can be abandoned.

As for task 3, it is very malleable and sounds attractive, but it is difficult to accomplish in the short term.

Even Vera, who has the most potential, even though the group construction method has paved the way for many additive number theory propositions, the difficulty of Kakutani's conjecture is beyond her ability.

Although Lu Zhou may be able to do it if he takes action himself, considering that the subject experience will be calculated based on student participation, it is likely that there will be a situation where it is obviously a major conjecture, but the experience rewarded is not satisfactory.

After some careful consideration, Lu Zhou finally chose Mission 2.

It's already the end of August, and it's not long before the end of the year, so the mission cycle won't be too long in the first place. The 1000:1 conversion ratio is a bit uncomfortable, but considering the patent granting, you can still gain a lot of experience.

The only thing that made him curious was what the 10% [special] in that lottery was.

With such a small probability of winning, I don't know if he has a chance to draw ......
