Chapter 298 Graphene Battery
When it comes to graphene batteries, Lu Shan feels a little complicated.
Graphene batteries are developed by utilizing the property of lithium ions shuttling rapidly and in large quantities between the graphene surface and the electrode.
Is this battery good? Yes! Is it difficult to make? Yes!
How difficult is it?
It’s so hard that it seems like a scam, it’s that hard.
Originally, single-layer graphene was obtained by simply sticking and tearing tape on the surface of a graphite block. For this nonsensical method, the scientist was awarded the Nobel Prize in Physics.
And then? Nothing happened.
Once it enters the production stage, you can't let workers keep tearing graphite blocks with tape, right? How can those single layers of graphene be used?
Because of this reason, the application of graphene in various fields is very slow.
According to Lu Shan's memory, the University of California, Los Angeles, has developed a micro supercapacitor that is said to have a charging speed 1000 times that of ordinary batteries. It can charge mobile phones and cars within seconds and can be used to manufacture small flagships.
Lu Shan was very skeptical about this news. At most, it was data from a specific laboratory environment, and safety was absolutely not considered. Otherwise, it would have been put into actual combat long ago.
Xia Guo did not have any battery skills in the use of graphene. Instead, it used chemical vapor deposition to produce a 15-inch single-layer graphene and used graphene transparent electrodes on resistive touch screens.
It’s not about whether the level is high or not, but...graphene should obviously have better and more meaningful applications.
Lu Shan discussed these situations of graphene with Mary. Of course, he would not say what he had seen in his previous life. Instead, he started from the characteristics of graphene and rationalized the development trajectory.
Mary nodded in agreement, but she still wanted to give it a try. After all, with the development of batteries today, except for graphene, there is no possibility of upgrading other things.
“I have read some papers that argue that sodium metal can replace lithium metal, but I think it is a waste of time. Sodium and lithium look similar in characteristics, but their atomic structures are very different. Sodium cannot replace lithium unless there are other elements to stimulate and control it.
If it is a liquid or semi-liquid battery, this substitution is more feasible.
But if it is a solid-state battery, such as mobile phones and laptops, there is no future. So the battery of the next era must change the material itself. ”Mary gave her own insights.
Lu Shan nodded and motioned for Mary to continue.
"From a microscopic perspective, the charging and discharging process of a battery is actually the process of cations embedding and detaching in the electrode. The more holes there are in the electrode material, the faster this process will be. This is why the charging efficiency of liquid lead batteries is much lower than that of solid batteries.
The microstructure of graphene is actually a network structure composed of carbon atoms. In addition, the thickness of graphene is only one layer of atoms, so the movement of cations is very limited, and the efficiency is not comparable to that of existing batteries. Moreover, graphene materials can charge themselves using the temperature of the environment, which can improve the battery life. "
At this point, Lu Shan immediately understood what Mary meant: "You mean, we can put graphene in some chemical liquids, such as copper chloride, right?"
"Mr. Lu is really smart." Only then did Mary recognize Lu Shan's professionalism. Before, she only thought that Lu Shan was a mathematician, communications expert, and materials scientist, and he was not very good at other things. She didn't expect Lu Shan to understand everything so quickly.
Lu Shan went on to say: "Because copper ions have a double positive charge, they can be violently loaded into the graphene ribbon at room temperature. Energy is generated in the collision, and electrons that are not in their original position will leave the graphene. Electrons will either leave the graphene ribbon or combine with copper ions, enter the graphene and then enter the circuit.
The electrons flow faster in graphene than in solution, so they flow into the circuit instead of back into the electrolyte, providing power.”
“However… this mode seems to be better used on larger devices, such as cars and electric vehicles, which can be reverse charged in room temperature.
If we can find a solid material to replace the electrolyte, we can apply this concept to mobile phones and laptops. Let's do it step by step. Let's solve the problem of batteries for mobile phones and laptops first.
In two or three years, mobile phones will be transformed into another type of product, and people will have a higher demand for mobile phone batteries. "Lu Shan did not aim too high, and after figuring out his ideas, he still proceeded from reality.
After leaving the Singularity Laboratory, Lu Shan searched for technical literature on batteries for mobile phones and laptops, and sent in whatever he could find so that Mary could find some clues.
Lu Shan has been busy with Mary for several days. He has to deal with the company's affairs. Fortunately, the company started with technology and has no foreign debt, so it only needs to develop normally.
Unless there is some crisis, such as being targeted by peers or the emergence of negative public opinion.
If it weren't for all that mess, Lu Shan's company would have developed quickly and well.
"This is Ji Yue's operating status last month. Please take a look at it." Zheng Kaige handed the report to Lu Shan. Lu Shan glanced at it and only captured the key data before leaving.
As long as there is key data, the actual situation can be deduced by working backwards. This is how Lu Shan does things, relying on efficient logic to make judgments.
In recent months, Lu Shan has rarely been to Jiyue, and when he went there it was always to Zemeng.
Because Jiyue has entered a healthy development, it only needs to follow its own technical route, and the direction of the route has long been determined. Lu Shan is just like checking the homework of a eugenicist, just take a look.
Zemeng still has a lot of technology to overcome, and usually people from Jiyue are seconded to do work, but there are already signs of isolation. Everyone has limited energy, and Lu Shan hopes that they can all focus on their own technical fields.
After so many times, Qiao Weiwei felt that she only saw Lu Shan once in a long time.
"You look like you want to take off my clothes!" Ma Lijuan appeared out of nowhere and said affectionately while lying on Qiao Weiwei's shoulder.
"I'm so scared! Don't talk nonsense!" Qiao Weiwei was obviously startled, which made Ma Lijuan laugh.
"Just be reserved! Just watch! If someone succeeds in knocking Lu Shan unconscious and dragging him away, you will regret it. You won't even smell the food, but your food has been eaten by others!"
"Why do you speak so harshly!" Qiao Weiwei blushed a little.
Ma Lijuan became serious, "Is it unpleasant to listen to? Why don't you take a look at the content on our Jiyue website occasionally? There is a topic forum about Lu Shan, and those women are even more extreme. It is considered civilized to say that they want to give birth to Lu Shan's children. Some are even discussing... positions."
"Bah! Shameless!" Qiao Weiwei spat.
Ma Lijuan shook her head: "Lu Shan is very popular. If the regular methods don't work, you really have to use some special methods." Then she smiled evilly: "I'm free tonight, you can ask her out for dinner, and I'll stand at the entrance of the alley and help you beat him up!"
"You...that is..." Qiao Weiwei held it in for a long time before finally saying, "That...is not good."
"A normal person would say that this is illegal and should not be done. What do you mean by your hesitation? Huh?" Ma Lijuan ran away with a smile.
Only then did Qiao Weiwei realize that Ma Lijuan was teasing her, so she chased after her and slapped her twice.
While running, Lu Shan forgot to tell Jiyue something, and suddenly turned back and walked into Jiyue. As soon as he entered, he saw Ma Lijuan and Qiao Weiwei running, and the three of them were suddenly stunned. The most embarrassing thing was that Qiao Weiwei still maintained the "Horse Stepping on Flying Swallow" posture, while Ma Lijuan was better, at least her hand was not stretched out.
Qiao Weiwei adjusted her posture at the speed of light, and Lu Shan thought his eyes were blurry. If Ma Lijuan had not slowly adjusted her posture, he would have thought he had really seen it wrong.
"Senior, please be careful..." Lu Shan said this and went to find Zheng Kaige.
"It's all your fault! It's so embarrassing!" Qiao Weiwei blamed Ma Lijuan with a blushing face.
"Well, that's nothing. People here can still shoot basketball normally. Lu Shan has given permission. As long as the work is done, you can lie down and do nothing."
Ma Lijuan didn't care, but she knew Qiao Weiwei cared, so she teased her: "How about I explain to him that I took your lollipop?"
"Hmph!" Qiao Weiwei immediately hid in the technical development area to work on the code.
Seeing this cowardly look, Ma Lijuan shook her head: "Qiao Weiwei, you should just wait to be the godmother of Lu Shan's child!"
A few days later, Lei Jun suddenly called. They had exchanged contact information last time in Shenzhen Stock Exchange.
When Lu Shan saw Lei Jun’s name, he knew that he was probably planning to make mobile phones.
Sure enough, after the call was connected, this was exactly what happened.
Lei Jun’s request is very simple. He hopes that his own mobile phone can use the Extreme Browser, because he cannot reach an agreement with other browsers. He hopes that Lu Shan can give some help.
Starting to develop a new mobile phone in his forties was a huge challenge for Lei Jun, as everything had to start from scratch.
I had to negotiate with suppliers about everything from filters, displays, batteries, to interfaces. Although we had not yet entered into large-scale negotiations and were still only doing internal testing, the difficulty of the negotiations was already beyond my imagination.
After the hardware was finally finalized, the software failed. The MIUI system is based on the Android system, but the browser has always had problems. The progress is very slow and the degree of adaptation is very low. It feels like it can't be integrated.
The reason is not difficult to understand. Lei Jun's thinking is relatively advanced. He knows the difference between UC and Jiyue's systems, so he wants to learn from Jiyue, but the Android system can no longer recognize some functions.
However, Xiaomi Company has no way to make the Android system understand its commands. That is something that Ji Yue can do, but it does not mean that others can do it.
As soon as the browser project got stuck, Lei Jun immediately held a meeting to let everyone express their opinions. It turned out that the technical staff had the same opinion as himself. The bachelors thought that there was no point in developing it and they should just cooperate directly with Jiyue.
"I'm not saying anything weird, but unless we come up with a new underlying logic architecture that's more efficient and smarter than Jiyue, no one will be able to outperform Jiyue Browser."
"That's right. Don't waste resources on this. You can continue to try to accumulate some experience, but you can't invest so much."
Lei Jun agreed with this. Lu Shan had the latest and most advanced mathematical achievements. Who could compare with him?
But why did Lu Shan cooperate with you, Xiao Mi? Because you drank with Lu Shan? Because you heard Lu Shan sing "Are You OK"?
Yes, it's really based on this.
When Lu Shan agreed, Lei Jun was still confused. He only had a mobile phone company with a PPT-level scale, so why could Lu Shan be so straightforward?
"Don't you have any other requests?" Lei Jun felt embarrassed for the first time.
"Have."
Lei Jun thought it was normal, but at the same time he became nervous, fearing that Lu Shan would make some request that he could not meet.
“Don’t use it for illegal purposes.”
"Any more?"
"Not for now. I'll let you know when I think of it."
"Thank you, Mr. Lu!"
"You're welcome."
When the people in Xiao Mi's company saw that their boss had obtained the right to use the Extreme Browser in such a grand manner, their eyes changed when they looked at him. A few partners were a little dissatisfied with Lei Jun, but now they were convinced.
When everyone was conducting internal testing, everyone in Xiao Mi's company felt that it would be better not to get this authorization because it was too discouraging.
During the test, the algorithm of Jiyue Browser was extremely accurate. Its intelligence level was comparable to that of Coco Assistant, except that it was not very communicative. However, it could recognize voice, convert it into text, and then search for content.
If the current mobile phones were not still 2G, the data traffic was tight and the speed was not increased, Lu Shan would have wanted to give all of Coco Assistant's features to Jiyue Browser a long time ago.
However, the current cooperating mobile phones are all Android systems. Jiyue has already achieved the ultimate. It is useless to be more advanced. Android is too stupid. Even if Jiyue is very smart and patiently communicates with the Android system, the Android system can no longer understand more content.
If the IQ is not lowered, it cannot be explained. If the IQ is lowered too much, it cannot be explained.
The key is to improve the intelligence of mobile phones.
Xiaomi’s employees were frustrated because they were also a startup team, and so was Ji Yue, but their products were so awesome.
Lei Jun accurately grasped the key point and encouraged his subordinates not to underestimate themselves. If they work hard, they will not be worse than Ji Yue. At least now Ji Yue is in urgent need of a mobile phone system that can understand and execute high-intelligence programs, right?
Xiao Mi starts from this aspect.
Lei Jun actually had a hunch in his heart that Lu Shan might also be developing a mobile phone system. If that was true, Xiao Mi would have another competitor!
Lei Bushi prayed that he would not have to run on the same track as Lu Shan.
Look at big companies like Microsoft and Lianxiang, who were on the same track as Lushan and tried to bully the smaller ones, but ended up getting beaten to a pulp.
The internal test passed with full marks. After trying the Git Browser, other browsers could not be used. At this time, the technicians raised new questions.
