Chapter 266: Materials Science, LV III!

Professor Krel's guess is correct.
When he returned quickly to the laboratory, the sample placed on the field emission scanning electron microscope did not smoke or explode, and everything was surprisingly good.
Through several sets of SEM images taken, it can be clearly observed that lithium ions are gradually deposited on the electrode protected by the modified PDMS film, just like a beautiful layer of silver tundra.
But this layer of "tundra" did not grow as wildly as in other lithium batteries, developing deadly dendrites, but lying quietly under the modified PDMS film, gently undulating over time.
Nucleation did not happen, or it happened, but it was channeled.
If nothing else, this state will be maintained until the entire charging process is completed.
There is no doubt that they successfully restored the experiment.
"incredible……"
Standing next to the computer, looking at the images continuously generated by the field-emission scanning electron microscope, Professor Kreer said three unbelievable sentences in a row, still unable to let out the shock in his heart.
Even though the same image has been posted in Natural Chemistry, it is far from intuitive to see it in person.
The Columbia TV reporter standing behind him was confused, wondering what the researchers were happy with.
Even standing here to witness the great moment, he could not see any mystery in these SEM pictures.
Out of confusion, he spoke.
"professor?"
Professor Creel turned back and looked at the reporter cheerfully.
"what's up?"
He is very happy now, very, very happy.
If the problem of lithium dendrites is solved, his laboratory will benefit directly. I believe it won't be long before his lab can get tens of millions or even hundreds of millions of dollars in investment for at least one MRS meeting.
What kind of posture did the industrial industry use to throw away the lithium battery? Now, what kind of posture do you have to invite it back?
The reporter swallowed and asked, "How is it?"
Professor Creel looked at him with certainty: "I can tell you now that it has succeeded."
Perhaps he didn't feel shocked enough, he paused for a moment and continued.
"Perhaps half a year, maybe a year, you can use a smartphone that has been on standby for a week. After a few years, you can see the Thrace that has thousands of kilometers of life outside the PPT ... Trust me, I The ox is definitely more reliable than yours. "
This statement may be exaggerated, but it is definitely not divorced from reality.
At present, lithium ion batteries are mainly based on graphite anodes, which can be calculated through the product LiC6. The theoretical specific capacity of graphite is 372mAh / g. If the cost is not considered, the number can be changed to 747mAh / g by graphene technology in the laboratory. .
As for the theoretical specific capacity of lithium?
It is 3860mAh / g.
Although many things cannot be directly applied to addition and subtraction, they can still be intuitively felt numerically. These four digits are crushed to three digits.
And in terms of cost, lithium metal and polydimethylsiloxane are completely acceptable.

[Congratulations to the host for completing the reward mission! 】
[The task is completed as follows: solve the lithium dendrite problem. 】
[Final evaluation of the task: none (no evaluation of reward task)]
[Mission reward: 70,000 materials science experience, 10,000 biochemical experience, wreckage. 】
In a pure white system space.
Looking at the experience revealed on the holographic panel, Lu Zhou's mouth could not help but smile.
It is indeed a technology of higher civilization, and even a small electrode brings considerable experience.
These experiences certainly cannot afford any splash in mathematics, but his material science and biochemistry are both LV1. Throwing these two disciplines directly made him feel like sitting on a rocket.
This reward task is probably the happiest one he has done.
"System, open the properties panel!"
With a flash of white light, the data panel quickly appeared in front of Lu Zhou.

Materials science has been upgraded two levels, to LV3, and now equal to physics. Biochemistry has also risen to the next level and is now LV2.
However, although Lu Zhou has read a lot of books and literature in this area under the guidance of system tasks, after all, he is not a full-time researcher in this field, and he still can't feel the improvement of the thinking ability of that discipline.
At least it wasn't as intuitive as math gave him.
Possibly, this is also related to the fact that the two disciplines do not rely so much on "inspiration".
After closing the property panel, Lu Zhou routinely looked at the nearby inventory.
The No. 2 wreck lying in the inventory is a black cube, about the size of a third-order Rubik's cube. From the appearance alone, it gives a very fascinating feeling.
Unlike the first wreckage of the battery, Lu Zhou took this item out of the inventory for a long time, but it was still foggy. I do n’t know what it was used for. .
Higher civilization toys?
It's not very similar.
As for weapons, let alone talk about them.
What's most fascinating is that there are no scratches on the surface of this cube, and Lu Zhou can't even see it. What went wrong with this stuff was only judged by the system as "debris" and sent to himself.
Setting aside this impenetrable thing temporarily, Lu Zhou continued to look at the taskbar.
The reward task is done.
Then you have to do "multiple choice questions".
Hopefully, some interesting tasks will come out.
Taking a deep breath, Lu Zhou stretched out his fingers and nodded.
[
Task 1: Keep improving
Note: The technology of lithium anode materials is not just modified polydimethylsiloxane film, but carbon nanomaterial spheres with flat cross-section folds are equally important.
Requirements: The product is successfully prepared in the laboratory and a paper is published.
Reward: 50,000 materials science experience. 500 points. Lottery opportunities (85% trash, 9% samples, 6% drawings)
】

Task 2: Even great work is inseparable from the support of the economic foundation
Note: The lab is like a black hole. Before the project is concluded, you, the project leader, will never know how much money you will spend. 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 funds yourself.
Requirements: From the beginning of the mission to the end of the year (December 31, 2016), calculate the personal assets of the host to increase the blessing.
Reward: 1-? ? ? Free experience ($ 1,000 = 1 free experience). 500 points. Lottery opportunities (80% trash, 10% special, 7% samples, 3% drawings).

Task 3: Scientific research is not an individual task
Explanation: The value of a top scientific researcher is not only in how much research he has completed, but also in how much talent he has cultivated. Although many scholars have died, the doctrines they left still influence and change the future.
Requirements: Train at least one student and complete a thesis.
Reward: 1-? ? ? Subject experience (the final experience is comprehensively evaluated by the academic value of the dissertation and student participation), with 500 points. Lottery opportunities (50% rubbish, 30% samples, 20% drawings)
】
Staring at these three tasks ~ EbookFREE.me ~ Lu Zhou thought for a long time.
Carbon nanomaterial spheres with flat cross-section folds are indeed important, but not decisively important.
For the higher civilization that created that "wreck", those folds are unacceptable flaws, but for any battery manufacturer on the planet, this flaw can be ignored.
After all, compared with modified polydimethylsiloxane film, the latter determines the vitality of the product, while 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 carbon nanospheres with hollow structures can not be copied even if they know the molecular structure and three-dimensional conceptual images under the conditions of Luzhou.
Combining these two reasons, Task 1 can be abandoned.
As for task 3, it is very malleable and sounds attractive, but it will be difficult to complete in the short term.
Even the most promising Vera, even though group construction has paved the way for many propositions of additive number theory, the difficulty of Kakutani's conjecture is beyond the scope of her ability.
Although Lu Zhou's own shot may be able to do it, considering that the subject experience will be calculated based on student participation, it is likely that in the end it is obviously a major conjecture, but the reward experience is not satisfactory.
After some careful consideration, Lu Zhou finally chose Task 2.
It is now the end of August and it is not long before the end of the year. The task period will not be too long at first. The conversion ratio of 1000: 1 is a bit uncomfortable, but considering the patent grant, it 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 will get a chance ...
