Professor Krell’s speculation is not wrong. .

When he returned to the lab, the sample placed on the field-emitting scanning electron microscope did not smoke, no explosion, and everything was amazing.

Through the interception of several sets of sem images, it can be clearly observed that lithium ions are gradually deposited on the electrode with the modified pdms film protection, just like a beautiful silver tundra.

But this layer of "tundra" did not grow as wild as in other lithium batteries, developing deadly dendrites, but lying quietly beneath the modified pdms film, undulating over time.

The nucleation did not happen, or it happened, but it was diverted.

Without an accident, this state will continue until the entire charging process is completed.

There is no doubt that they successfully restored the experiment.

"incredible……"

Standing next to the computer and looking at the images generated by the field-emitting scanning electron microscope, Prof. Krell said that the three sentences were unbelievable and still could not vent the shock.

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

The Colombian TV reporter standing behind him was confused and didn't understand what the researchers were happy about.

Even if he stood here to witness the great moment, he could not see any mystery on these sem maps.

Out of confusion, he spoke up.

"professor?"

Professor Krell returned to the world and looked at the reporter with a fascinating look.

"what's up?"

He is very happy now, very very happy.

If the problem of lithium dendrite is resolved, his laboratory will benefit directly. I believe that it will take a long time to get the investment of tens of millions or even hundreds of millions of dollars in the lab.

What kind of posture did the industry use to abandon the lithium battery, and now you have to use it to get it back.

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

Professor Crael looked at him with a positive look: "I can tell you now that I have succeeded."

Perhaps he felt that his statement was not shocking enough. He paused for a moment and continued.

"Maybe half a year, maybe one year, you can use a smart machine that is on standby for a week. In a few years, you can see thousands of kilometers of Trass outside the ppt... Believe me, I The cows that are blown are definitely more reliable than the ones you blow."

This statement may be exaggerated, but it is definitely not out of touch with reality.

Lithium-ion batteries are mainly based on graphite anodes and can be obtained by calculation of product li6. The theoretical specific capacity of graphite is 372mah/g. If the cost is not considered, the figure 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 can't be directly applied to addition and subtraction, they can still be intuitively perceived from the figures. These four digits are pressed against three digits.

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

......

[Congratulations to the host to complete the reward task! 】

[The task is completed as follows: Solve the problem of lithium dendrites. 】

[Question final evaluation: no (reward task no evaluation)]

[Task reward: 70,000 materials learning experience, 10,000 biochemical experience, wreckage. 】

In a pure white system space.

Looking at the experience tips on the holographic panel, Lu Zhou’s mouth could not help but smile.

It is worthy of the technology of higher civilization, even a small electrode, the experience is quite considerable.

These experiences are mathematically sure to despise what kind of water, but his material science and biochemistry are both lv1, thrown in these two disciplines, directly let him feel the feeling of sitting on the rocket.

This reward task is probably the most enjoyable one he has ever done.

"System, open the properties panel!"

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

a. Mathematics: lv5 (54000/300,000)

b. Physics: lv3 (53100 / 100,000).

Biochemistry: lv2 (4000/5 million)

d. Engineering: lv1 (0/10000)

e. Materials Science: lv3 (13000 / 100,000)

f. Energy: lv1 (0/10000)

g. Informatics: lv1 (3000/10000)

Points: 2475

Material science has risen two levels, to lv3, now and physical level. Biochemistry has also risen to the next level, now it is lv2.

However, although Lu Zhou has read many books and literatures in this field under the guidance of system tasks, it is not a full-time researcher in this field. For the time being, the improvement of thinking ability in that subject is still not felt.

At least not as intuitive as the mathematics brought to him.

Possibly, this is also related to the fact that the two disciplines are not so dependent on “inspiration”.

After turning off the property panel, Lu Zhou routine looked at the item bar next to it.

The wreck No. 2 lying in the inventory is a black cube, the size is similar to a third-order cube, which gives a very fascinating feeling from the appearance.

And at a glance, it can be seen that the wreckage of the battery is different. For this unknown thing, Lu Zhou took it out of the inventory for a long time, still a fog, I don’t know what it is used for. .

High civilization toys?

Not too much like it.

As for weapons, I can’t talk about it.

The most fascinating thing is that there is no scratch on the surface of this cube, and Lu Zhou can't even see it. If there is something wrong with this gadget, it is judged by the system as “wreck” and sent to him.

Putting this unsearchable thing aside for a while, Lu Zhou continued to look at the taskbar.

The reward task is done.

Then I have to do a "multiple choice question."

I hope that I will brush out some interesting tasks.

Taking a deep breath, Lu Zhou extended his finger and clicked up.

Task 1: Keep improving

Note: The technology of lithium anode materials is not only the modified polydimethylsiloxane film, but also the carbon nanomaterial pellets with flat cross-section folds.

Requirements: The product was successfully prepared in the laboratory and a paper was published.

Reward: 50,000 material learning experience. 500 points. Lottery opportunities (85% garbage, 9% sample, 6% drawings)

【

Task 2: Even a great job cannot be separated from the support of the economic base

Explanation: The lab is like a black hole. Before the project is completed, as the project leader, you never know how much it will cost. Maybe you have confidence in your work, but your partner is not necessarily as confident as you. Instead of being subject to people, it is better to raise money.

Requirements: From the beginning of the task collection until the end of the year (December 31, 16), calculate the personal assets of the host.

Reward: 1-? ? ? Free experience ($1,000 = 1 free experience). 500 points. Lottery opportunities (80% garbage, 10% special, 7% samples, 3% drawings).

【

Task 3: Research is not a human task

Explanation: The value of a top researcher is not only how much research he has done, but also how many talents he has cultivated that are not inferior to him. Although many scholars have passed away, the doctrines they left still influence and change the future.

Requirements: Train at least one student and complete the thesis.

Reward: 1-? ? ? Subject experience (final experience is assessed by the academic value of the paper and student participation), with a score of 500 points. Lottery opportunities (50% garbage, 30% sample, 20% drawings)

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

The carbon nanomaterial pellets with flattened cross-sections are indeed important, but not critical.

For the higher civilizations that created the "wreck", those folds are unacceptable, but for any battery manufacturer on the planet, this is negligible.

After all, compared to the 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 completely exploded the graphite anode.

And the most important thing is that those hollow carbon nanospheres can't be copied even if they know the molecular structure and three-dimensional conceptual image.

For these two reasons, Task 1 can be abandoned.

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

Even the most promising Vera, even though the group construction method has paved the way for many propositions of additive number theory, the difficulty of the Gu Gu guess is beyond the scope of her ability.

Although Lu Zhou may be able to do it himself, considering that the subject experience will be calculated based on student participation, it is likely that there will be a major conjecture in the end, but the reward experience is unsatisfactory.

After some deliberation, Lu Zhou finally chose Task 2.

It is now at the end of August, not far from the end of the year, and the task cycle will not be too long. The conversion ratio of 1000:1 is uncomfortable, but considering the patent authorization, you can still get a lot of experience.

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

With such a small probability of winning, I don’t know if he has the opportunity to draw...
