Chapter 185: The effect is unexpected

The sky was bright outside the window.
I do not know when to lie on the sleeping boat on the table, rubbed his eyes, moved his stiff arm, and stood up from the chair.
Then, the first thing he stood up was to wait for the digital microscope and inspect the sample under the microscope.
No explosions and no smoke.
Seeing that the samples were intact, Lu Zhou was happy, and then looked at the computer next to him, passing the photos as fast as a slideshow.
"It's done!"
With his fists clenched, he almost exhaled.
From yesterday afternoon to the present, he has done a total of four sets of charge and discharge cycles without lithium dendrites once!
The lithium ions flying to the negative electrode did not form a white branch, but a layer of moss-like folds was deposited under the PDMS material, and layered upwards.
From the data on the BK-6808 rechargeable battery tester, not only did lithium dendrites not form, even the Coulomb efficiency was maintained at a fairly high level!
The good effect surprised Lu Zhou.
He originally thought that at least it was necessary to combine PDMS materials with those carbon nanosequences to completely solve the lithium dendrite problem. The result was unexpected, even if the PDMS material was pulled out alone, the effect was amazing.
As for the role of those carbon nanosequences, Lu Zhou maintained previous speculation that, in addition to accelerating the rate of lithium ion precipitation, it is probably used to "flatten" the folds under the PDMS material.
As for those mossy "folds", the effect on battery performance must be faint, but at least it is much better than the deadly lithium dendrite!
Without those sequences, as the battery continues to charge and discharge, the wrinkling phenomenon intensifies. Although it will not pierce the lithium dendrite, the Coulomb cycle efficiency will definitely decrease, which will reduce the battery's service life.
Perhaps this flaw is unacceptable for advanced civilization, but for any company on the planet, this flaw is simply negligible.
Under the premise of safety, without reducing the service life of the battery, net cutting may increase the energy density of the battery, which is the industry's biggest pursuit!
It's as if someone's cell phone is full of electric energy, brush the scarf for a week, play a week of games, and your cell phone is full of electricity and it will be red in less than half a day.
Of course, this comparison may be a bit exaggerated. There are many factors that affect battery performance. The specific endurance depends on how the battery and the chip that controls the battery are designed. This part is difficult for Luzhou to intervene.
But there is no doubt that this new type of anode material will provide endless imagination for the entire industry!
Whether it is a widely used lithium borate battery or a lithium manganese cobalt battery in the market, the anode is mainly graphite. As for the lithium-sulfur battery that is still lying in the laboratory, it is kneeling at the feet of lithium dendrite dad and singing to conquer.
Therefore, Lu Zhou is very clear about what he has achieved in the past half month.
Taking a deep breath, he closed his eyes and meditated.
"System, what about those carbon nanosequences?"
The system did not respond.
Opening his eyes, Lu Zhou stared softly at the sample on the microscope.
"Is that so?"
As he expected, the technologies contained in those carbon nanosequences have exceeded his material science level. Just like the membranes that screen oxygen molecules, he has not yet had the authority to access that information.
It doesn't really matter if you don't.
The data scanned from the rammer was stored in his computer, and not everything had to be solved by the system.
It's a matter of time before his own laboratory is set up, and a group of researchers are hired to help him work to restore the technology inside.
Unplugged, Lu Zhou stored the battery sample under the microscope in a prepared row.
Immediately after, he saved the photos on the digital microscope and the data on the BK-6808 rechargeable battery tester to a USB flash drive. As for the original data stored on the device, he was completely destroyed.
After cleaning the laboratory and confirming that there were no
interesting
things left, Lu Zhou left the laboratory in a happy mood, and returned the key to Teacher Wang, who is in charge of managing the laboratory equipment.
Coincidentally, when going out, Lu Zhou met Brother Qian.
Seeing Lu Zhou, Brother Qian greeted and said, "Done the experiment?"
Lu Zhou smiled and said, "It's done."
Originally, he only had a face-to-face meeting, and Lu Zhou suddenly thought of something and stopped Brother Brother Qian who was about to enter the office.
"Yes, are you working on electrode materials?"
In the second half of last year, when Lu Zhou was helping Professor Li to do the project, he heard that he had talked about what electrode materials related topics this year.
"Yes," Brother Qian nodded and asked with a smile, "Are you interested?"
Lu Zhou did not answer this question, but instead asked, "What kind of project are you?"
Not something worth keeping secret, Brother Qian replied in a gossip: "The positive electrode material of lithium-sulfur batteries. The latest research results of the Mashu University of Technology found that fixing sulfur in mesoporous carbon materials as a positive electrode material can Effectively slow down the growth of negative lithium dendrites. As for more specific things, I will not be able to say more, and signed a confidentiality agreement. If you are interested, Professor Li will certainly welcome you to join our team. "
"Forget it, Academician Lu will definitely not be happy when I see the fish." Lu Zhou smiled, hesitated for a while, and said, "Moreover, I don't think this is a good paper for you. I have seen that I am actually doing similar research. "
With the wording in mind, Lu Zhou continued.
"But I think that if this discovery is really important, the research team at Mashu University of Technology is unlikely to publish it to the journal so easily, at least not in such a hurry."
The technology that has been published cannot be applied for patent, because it will conflict with the "newness" of patent laws in various countries.
Although it does not rule out that selfless research workers benefit the society, in general, those laboratories with investment from enterprises (mainly engineering), for high-value research results, usually use heat to register patent protection research results, and then publish theses. Kind of model.
It's very unlikely that it will be thrown into a journal so easily, and similar things have not happened before, even in the field of batteries.
About 2011, a paper on aluminum ion batteries published by the L-Archer research group of Cornell University in the JECS journal proposed a battery model with Al as the negative electrode and V2O5 as the positive electrode ~ www.mtlnovel. com ~ has been widely reported as a "breakthrough" in the battery industry, and even highlighted by the well-known journal Sce.
It is not easy to say whether these people have been cheated of funds. In the end, the end is that this has proven to be an oolong.
At the MRS conference, a man at Cornell University was "hanged up" with convincing data by a named Luke Reed and had no power to fight back
Lu Zhou does not know whether the research results of Mashu University of Technology are correct, but he does know that starting from the cathode material, there is no future to study how to suppress the growth of lithium dendrites.
Because, he has completely solved the problem.
Even more, the patent will be registered soon.
Brother Qian swayed and said, "We will use experiments to test whether it is feasible. There is nothing to talk about."
After hearing what Brother Qian said, Lu Zhou could only sigh slightly and said with a smile.
"Good luck to you."
He couldn't reveal any more.
Even if we go on, no one will believe it, but will easily offend people. What's more, many things are not clear at all and can only be played down.
Out of the old days, the reminders he can make can only be so far.
However, he does not have to worry about what kind of expressions should be used to face the problem of the old professor and two old teammates who have fought side by side after the paper was published.
As soon as possible, his patent will have to wait until next year before he can start writing a manuscript.
Not surprisingly, he was already in Princeton at that time.
Maybe, by then, maybe Professor Li had given up this unreliable subject?
