Professor Kerr was right.
When he quickly returned to the laboratory, the sample placed on the field emission scanning electron microscope did not smoke or explode. Everything was surprisingly good.
Through several sets of SEM images, it could be clearly seen that lithium ions gradually deposited on the electrode protected by the modified PDMS film, like a beautiful silver tundra.
However, this layer of "tundra" did not grow wildly like other lithium batteries and develop deadly dendrites. Instead, it quietly lay under the modified PDMS film and undulated over time.
The phenomenon of nucleation did not occur, or perhaps it did, but it was diverted.
If there were no accidents, this state would continue until the entire charging process was completed.
Without a doubt, they had successfully replicated the experiment.
"Unbelievable …"
Professor Kerr stood next to the computer and looked at the images generated by the field emission scanning electron microscope. He couldn't believe it, but he was still shocked.
Even though the same image had been published in Nature Chemistry, it was not as intuitive as seeing it in person.
The Colombian TV reporter standing behind him was confused. He didn't understand what these researchers were happy about.
Even though he was standing there and witnessing this great moment, he couldn't see any mysteries in these SEM images.
Out of confusion, he spoke.
"Professor?"
Professor Kerr snapped back to reality and looked at the reporter with a pleasant smile.
"What is it?"
He was happy, very, very happy.
If the problem of the lithium dendrites was solved, his laboratory would directly benefit. He believed that it wouldn't be long before his laboratory would receive tens of millions or even hundreds of millions of USD in one MRS conference.
The industry had abandoned lithium batteries in the past, and now they had to bring them back.
The reporter swallowed his saliva and asked, "How's the situation?"
Professor Kerr looked at him and said, "I can tell you that it's a success."
Perhaps he felt that his words were not shocking enough, so he paused for a moment before continuing.
"Maybe in half a year, maybe a year, you'll be able to use a smartphone that can be on standby for a week. In a few years, you will be able to see a Tesla with a range of thousands of kilometers in places other than PowerPoint … Trust me, my bragging is definitely more reliable than yours. "
This statement might be exaggerated, but it was definitely not far from reality.
Currently, lithium-ion batteries mainly used graphite anodes. Through the calculation of LiC6, the theoretical specific capacity of graphite was 372 mAh/g. Regardless of the cost, this number could be increased to 747 mAh/g using graphene technology in the laboratory.
As for the theoretical specific capacity of lithium?
It's 3860 mAh/g.
Although a lot of things couldn't be directly applied with addition and subtraction, they could still intuitively feel the crushing power of a four-digit number over a three-digit number.
In terms of cost, lithium metal and polydimethylsiloxane were completely acceptable.
…
[Congratulations, host, for completing the reward mission!]
[Mission completion details are as follows: Solve the lithium dendrites problem.]
"Final Mission Evaluation: None (Reward Missions have no evaluation)"
[Mission reward: 70,000 materials science experience points, 10,000 biochemistry experience points, debris.]
In the pure white System Space.
Looking at the experience prompt that popped up on the holographic panel, Lu Zhou couldn't help but smile.
No wonder this was a technology from an advanced civilization. Even a small electrode brought a considerable amount of experience points.
These experience points wouldn't make much of a difference in mathematics, but his materials science and biochemistry were both level 1. These two subjects made him feel like he was sitting on a rocket.
This reward mission was probably the most enjoyable one he had ever done.
"System, open my characteristic panel!"
A white light flashed and the data panel quickly appeared in front of Lu Zhou.
【
A. Mathematics: Level 5 (54000/300,000)
B. Physics: Level 3 (53100/100,000)
C. Biochemical Engineering and Materials Science: Level 3 (13000/100,000)
F. Energy and information science general points: 2,475
】
Materials science went up two levels in a row and reached level 3, which was now the same level as physics. Biochemistry also went up one level and was now level 2.
However, even though Lu Zhou read a lot of books and documents under the guidance of the system mission, he wasn't a professional researcher in this field, so he couldn't feel the improvement in his thinking ability.
At least, it didn't feel as intuitive as mathematics.
Maybe this was because these two subjects didn't rely on "inspiration".
After Lu Zhou closed his characteristic panel, he looked at his inventory.
Debris No.2 was a black cube about the size of a Tier-3 Rubik's Cube. However, it gave off an enchanting vibe.
Unlike Debris No. 1, which was obviously a battery, Lu Zhou took it out of his inventory and looked at it for a long time. He was still confused as to what it was used for.
A toy from an advanced civilization?
Doesn't seem like it.
As for a weapon, it's definitely not a weapon.
The most confusing thing was that there were no scratches on the surface of this cube. Lu Zhou couldn't even tell what was wrong with this thing. Why was it sent to him as a "wreckage"?
Lu Zhou put this unknown thing aside and looked at his mission panel.
The reward mission was completed.
Now, he had to do another "multiple choice" question.
Hopefully, there will be some interesting missions.
Lu Zhou took a deep breath and clicked on it.
【
Mission 1: Keep improving.
Description: The lithium anode material technology isn't just about modifying polydimethylsiloxane film. Flattening the cross-section folds of carbon nanomaterials is also important.
Requirements: Successfully prepare the product in the laboratory and publish a thesis.
Reward: 50,000 materials science experience points. 500 general points. One lucky draw ticket (85% garbage, 9% samples, 6% blueprints)
】
【
Mission 2: Even great work can't be done without the support of a financial foundation
Description: The laboratory is like a black hole. As the person in charge of the project, you never know how much money you have to spend. You might be confident in your work, but your partner might not be as confident. Instead of being controlled by others, it's better to raise your own funds.
Requirements: From the beginning of the mission until the end of the year (December 31, 2016), calculate the increase in the user's personal assets.
Reward: 1-??? Free experience points (1000 USD = 1 free experience point). 500 general points. One lucky draw ticket (80% garbage, 10% special, 7% samples, 3% blueprints).
】
【
Mission 3: Scientific research is not a one-man mission
Description: The value of a top researcher is not only in how much research he has completed, but also in how many talents he has trained. Although many scholars have passed away, the theories they left behind still affect and change the future.
Requirements: Train at least one student and complete a graduation thesis.
Reward: 1-??? Subject experience points (Final experience points are based on the academic value of the thesis and student participation). 500 general points. One lucky draw ticket (50% garbage, 30% samples, 20% blueprints)

Lu Zhou stared at these three missions and thought for a long time.
Carbon nanomaterial pellets with planar folds are important, but not decisively so.
For the advanced civilization that created the "debris", those folds were unacceptable flaws. However, for any battery manufacturer on Earth, these flaws could be ignored.
After all, compared to the modified polydimethylsiloxane film, the latter determined the vitality of the product, while the former only determined the product's market competitiveness.
The superiority of the lithium anode material itself was superior to the graphite anode material.
Most importantly, the hollow carbon nanomaterials could not be replicated by Lu Zhou even if he knew the molecular structure and three-dimensional conceptual image.
Combining these two reasons, Lu Zhou could give up on Mission 1.
As for Mission 3, it sounded very attractive, but it would be difficult to complete in a short period of time.
Even Vera, who had the most potential, had paved the way for many additive number theory propositions using the Group Structure Method. The Collatz conjecture's difficulty was beyond her abilities.
Although Lu Zhou might be able to do it himself, considering that the subject experience points were calculated based on the student participation, it was very likely that the experience points would be unsatisfactory even though it was a major conjecture.
After some careful consideration, Lu Zhou finally chose Mission 2.
It was already the end of August, and the end of the year was not far away. The mission cycle would not be too long. The 1000: 1 conversion ratio was a bit uncomfortable, but considering the patent authorization, he could still get a lot of experience points.
The only thing that made him curious was what the 10% special was.
