Section 223
Just like that, after an unknown amount of time, finally——
"Done!"
Xiao Yi picked up a piece of yellow crystalline film with tweezers. Because it has good mechanical properties, it will not bend even in the form of a film, just like a piece of yellow glass.
In fact, its structure is indeed like glass.
At the same time, because it has better surface stability than pure lithium phosphorus sulfur chlorine, this thing that should not be directly exposed to the air is not afraid of air erosion at this time.
According to theoretical calculations, even if it is exposed to the air for a week, its performance will not change much. According to estimates, even if it is exposed for a month, it will only cause its performance to drop by about 1%.
Admittedly, a battery that loses 1% of its battery performance every month is definitely unqualified in the mobile phone industry.
But the problem is that this electrolyte will not be like a liquid lithium-ion electrolyte, which will catch fire due to contact with air.
Probably the only thing to worry about is that if the power is lost too quickly, the battery may be seriously damaged just after the phone is out of warranty.
Well... this should be considered as worrying too much, after all, the premise is that the battery is broken.
Of course, it is really unfair to discuss safety alone for such a solid electrolyte.
The biggest role of such an electrolyte is naturally its energy density that far exceeds that of a liquid electrolyte.
"Let's start. Let's witness how much our battery performance can reach with its blessing!"
Xiao Yi said.
"Yes!"
Liu Xiaodong and his team couldn't wait.
Then, the battery assembly began.
Metallic lithium as the negative electrode, and the new lithium phosphorus sulfur chlorine as the electrolyte. At the same time, the previous carbon nanoporous material was attached to the lithium phosphorus sulfur chlorine solid electrolyte through the solution coating method.
Finally, the sulfide polyacrylonitrile as the positive electrode.
The battery assembly was completed and the charge and discharge test began.
The number of cycles of this charge and discharge experiment was fifty times!
...
A few days later.
Fifty cycles were completed.
As the final results were counted, the entire laboratory fell into shocked silence.
Energy density: 1231Wh/kg!
You know, the current various lithium batteries, the highest energy density is only about 300Wh/kg.
This is more than four times the energy density increase, which is really...
It's amazing!
Facing this result, Xiao Yi also smiled slightly.
In theory, the energy density of lithium-sulfur batteries can reach about 2600Wh/kg.
Of course, this is ignoring all other masses.
In actual batteries, the mass of electrolytes, conductive additives, binders and other structural materials needs to be added, so it is generally lower.
Even with the mass of these other materials, it can still reach 1231Wh/kg, which undoubtedly shows how powerful the performance of this battery is.
Perhaps, mobile phones that can be used for three or four days without charging, or pure electric vehicles with a range of 2,000 kilometers, will be realized one by one in the near future.
To use a classic line: the future is here.
Of course, it's a bit too early to open the champagne now, after all, there are still some other tests that have not been carried out.
For example, the lithium dendrite problem.
But in fact, they had already tested that lithium dendrites were not a problem under the suppression of the new carbon nanoporous material.
Therefore, in the following experimental process, this new battery continued to show its extremely superior performance.
Conservatively estimated to have a cycle life of 1,500 times, and lithium dendrites will not grow excessively under the most extreme conditions, and extremely stable performance regardless of high or low temperatures...
This will be the strongest battery of the new era that will completely change the world!
Chapter 202 Yangtze River Scholars, the battery industry is shaking
Time passed quickly.
For the next half month, Xiao Yi and his team tested the various properties of this new battery in the laboratory.
As more and more experiments were done, the final statistical data all showed the excellent performance of this new battery.
Of course, theoretically speaking, it is normal to have such excellent performance.
This is the significance of technological breakthroughs.
"After the final optimization design, the energy density of the battery can now be stabilized at 1345Wh/kg. Well, to this extent, it has basically reached a limit."
Xiao Yi held a small cube in his hand.
This small cube is the battery they specially packaged, which includes all the parts of a battery.
In addition to the positive and negative electrodes and the lithium-phosphorus-sulfur-chlorine solid electrolyte, it also includes conductive additives, binders and battery packaging.
Only in this way can it be considered a commercial battery.
"Yes, Brother Xiao, if you want to continue to optimize it, you need to optimize the materials of other parts." Tang Chunming nodded next to him.
"Brother Xiao, you don't want to optimize the other materials together, do you?"
Liu Xiaodong asked "horrified".
Xiao Yi smiled and waved his hand: "That's not the case. There is no point in optimizing the other materials. It has nothing to do with us."
"Anyway, even if we apply for patents, we will only apply for patents for these three material technologies, not battery design patents."
"Let's leave battery design to those manufacturers."
Optimizing other materials actually has little impact on battery performance. After all, the performance of this battery is mainly based on lithium-sulfur batteries and solid electrolytes. After so many years of iteration in the market, the other materials have actually reached a similar level.
Liu Xiaodong and others nodded.
"Okay, in this case, our project is basically coming to an end."
And the next thing to do is to apply for patents and then publish papers.
Although these three things are advanced, they are not as complicated as high-temperature superconductors, so we still have to be careful of others finding a way to synthesize them.
So patents still need to be applied for.
As for patents, Xiao Yi still considered the laboratory, so he accounted for 80% of the beneficiaries, and the laboratory accounted for 20%.
This 20% is naturally also for the preparation of the subsequent construction of the laboratory.
Although it is still unknown how much money this patent can make, just considering the market size of the entire battery market of 100 billion US dollars per year, it is almost imaginable how much profit this 20% can bring to the laboratory.
Xiao Yi even felt that he could directly make the Science Island Laboratory one of the richest laboratories in the world.
At that time, part of the money will be used to improve the laboratory's treatment, part of the money will be used to support the laboratory's projects, and the rest will be used to expand the laboratory in the future, and strengthen the laboratory's infrastructure, etc.
Well...
He, the laboratory director, is really worried about the future development of the laboratory!
He was slightly moved in his heart.
He quickly came back to his senses, and then he said: "Okay, let's stop here today, and then write the paper first, and then wait until the patent number is obtained, and then publish the paper."
"Well... You can publish the paper wherever you want. I only need the corresponding author. You can divide the first and second authors by yourselves. Anyway, there are three papers."
Although he will not submit to foreign journals again, it is because he does not need foreign journals to prove himself.
As for Liu Xiaodong and the other three, they still need such top journal papers to gild themselves, which is also closely related to their future.
Xiao Yi will naturally help in this matter.
When the four heard Xiao Yi say this, their eyes widened.
What?
The first author of these three papers... can all be given to them?
Really?
There is such a good boss?
Although Xiao Yi is the corresponding author, it is also a great honor for them to be the first author!
Especially they have already prepared that these three papers will not be published, but will only be posted by Xiao Yi on his personal website.
As a result, now, they can not only choose the first author, but also publish them.
Each of these three important materials has great economic value, and they can be published in top journals at any time.
Of course, considering the conflict between Xiao Yi and Nature, they will definitely not submit to Nature.
So, without saying anything, the four people expressed their gratitude.
