Although Luyang has solved the industrial production of graphene, it does not mean that the research of graphene batteries can be smooth. Pen, fun, and www.biquge.info

Due to the short research time of graphene, the research and development of many applications is just beginning, including graphene batteries. Graphene battery is actually a new energy battery developed by using the characteristics of lithium ions to shuttle quickly and heavily between the graphene surface and electrodes.

Compared with traditional lithium batteries, the biggest advantage of the new battery developed by combining graphene materials with lithium batteries is that the charging efficiency has been improved, and the capacitance has basically not changed. Just like Huo Sheng's latest graphene battery, the capacitance is not better than the lithium battery in the laboratory, but the charging and discharging efficiency has been improved dozens of times, which is their current research results.

"Boss, if you want to continue to increase the capacitance, the road of graphene batteries may not work."

Huo Sheng showed Lu Yang the results of their research in the past six months, and at the same time put forward his own suggestions.

"Do you have a new direction?"

"Already." Huo Sheng is a qualified manager and a smart subordinate, and if there is no follow-up plan, he will not raise this issue to Lu Yang.

"When we were studying graphene batteries, we found that graphene is more suitable for another application than batteries, and that is supercapacitors. Graphene has a unique two-dimensional structure and excellent inherent physical properties, and the supercapacitor made of graphene can not only store more energy, but also charge and discharge 1000 times faster than ordinary batteries, which is a very ideal energy storage device. Huo Sheng introduced.

"Is this research yielding results?" Lu Yang asked, he didn't comment on Huo Sheng's statement.

"The laboratory cooperated with Tianxin Technology Research Institute to create a miniature graphene supercapacitor, which is smaller than an ordinary smartphone battery, but has a capacity of eight times that of an ordinary lithium battery. Although there is still a gap with our strongest lithium battery, we believe that graphene supercapacitors have greater potential. Huo Sheng said.

Lu Yang didn't know much about graphene battery technology, and he only bought lithium battery technology. However, from Huo Sheng's introduction, he saw the potential of graphene supercapacitors. Moreover, this miniature graphene supercapacitor has a similar function to a battery and can be applied to smart electronic devices.

"It's a good direction, how about the cost?" Lu Yang asked.

Huo Sheng's expression was slightly embarrassed: "The biggest disadvantage of micro graphene supercapacitors is the cost, compared with lithium batteries with the same performance, its cost is 3 to 5 times higher......"

Lu Yang didn't criticize Huo Sheng because of this, but said: "According to your current technological progress, how long will it take to reduce the cost?" ”

"The cost control is multifaceted, because the price of graphene is inherently higher than that of lithium batteries. With the current graphene production technology, in the short term, the price is unlikely to drop much, and the route we are taking now is to expand the capacitance as much as possible to improve its cost performance. Huo Sheng explained.

"This is also a ...... idea," Lu Yang affirmed Huo Sheng's thoughts.

"What about research on metal-air batteries?" Lu Yang asked again.

Metal-air batteries are also the direction that Lu Yang determined at the beginning, including zinc-air batteries, lithium-air batteries and aluminum-air batteries, three types of battery technology, Lu Yang bought, in order to obtain a practical, larger capacity battery when large-capacity lithium battery technology can not be broken through.

"We have accumulated the deepest accumulation in the research of lithium batteries, and we have made the first breakthrough, the first generation of practical lithium-air batteries has come out, but compared with our large-capacity lithium batteries, it has no advantages."

Lu Yang didn't care, he knew that the reason why it was like this was because the technology was not up to par. In fact, the potential of metal-air batteries is very high. Taking a lithium-air battery as an example, since oxygen in the air is used as the active substance on the cathode, the capacity density of the cathode is theoretically unlimited, and the capacity can be increased. In addition, if lithium metal is used for the anode, the theoretical capacity will be increased by one digit compared to lithium-ion rechargeable batteries.

As far as the current research is concerned, there are still many drawbacks to be overcome in lithium-air batteries, such as lithium oxide (Li2O), a solid reaction product, that accumulates at the positive electrode, blocking the contact between the electrolyte and the air, resulting in a halt in discharge. However, none of this is a problem for Lu Yang.

If Lu Yang had been willing, he would have been able to produce a lithium-air battery with an energy density twenty times that of an ordinary battery, but the reason why he didn't do so was because the current large-capacity lithium battery could still meet the current needs. Moreover, once this kind of battery is launched, large-capacity lithium batteries are bound to be eliminated, and the loss is Tianxin Super Energy's own.

On the other hand, Lu Yang also hopes that the technical team of Tianxin Super Energy can do some accumulation to cope with the rapid development of future technology, and it doesn't matter if the research speed is slower and take a little detour.

Lu Yang couldn't say these words to Huo Shengzhi, so he could only point him out in his usual work.

"One more point, Lao Huo, how is your research on automotive batteries?"

Huo Sheng smiled bitterly: "Boss, the large-capacity lithium battery technology was invented by you, you should know that it is very suitable for use in mobile phones and computers, but it cannot be directly used in car batteries." The storage capacity of car batteries is very large, and it is difficult to improve their energy density with high-capacity lithium battery technology. As for the battery on the Galaxy sports car, we still took a trick. If we want to develop a battery that is truly suitable for automobiles, we need to increase the energy density of lithium batteries by at least 6 to 7 times, which we can't do now. ”

Lu Yang sighed secretly, he originally wanted to hand over this project to Tianxin Super Energy Company to complete independently, but now it seems that the company's research in this area is still not enough.

"In this regard, Tianxin Technology Research Institute has made some breakthroughs, on the basis of existing research, to increase the energy density of car batteries by 2 to 3 times, according to their experiments, two car batteries, can support the Galaxy sports car to travel 1,300 kilometers. Compared to before, it has improved a lot. After that, you can contact Professor Zhang, concentrate your efforts, and make a bigger breakthrough as soon as possible! ”

For the automobile industry, Lu Yang is very important, especially the development of electric vehicles in the future, he hopes that he can take advantage of the first, if he can monopolize the battery of electric vehicles like the monopoly of electronic products, then the world's car manufacturers have to look at Lu Yang's face. Thinking of this prospect, Lu Yang's heart was secretly refreshed, and when the time came, he would see Fusang Guo dancing happily......

On the weekend, Lu Yang didn't go anywhere, and at home with Zhu Xiaotong to teach the child prenatally.

Zhu Xiaotong has been pregnant for more than 6 months, and her belly is already very obvious. When she was out not long ago, she was photographed by a reporter. Soon, the people of the whole country knew that Lu Yang was going to be a father, and the congratulations from friends and partners made Lu Yang's mobile phone ring for several days, and it was finally quiet during this time.

"Xiaotong, do you say our children are boys or girls?" Lu Yang and Zhu Xiaotong listened to the Chinese classical musical instrument together and asked softly in her ear.

has been pregnant for so long, Zhu Xiaotong could have tested the child's gender, and the family also urged her, but Zhu Xiaotong insisted on not going, and the family could only follow her.

Zhu Xiaotong glanced at him: "Do you want a boy or a girl?" ”

Lu Yang hugged her and said, "For me, my son and daughter are good. If it were my son, he would be able to take over my class in the future, and as for my daughter, I would make her the happiest princess in the world! ”

"Can't my daughter take over your class?" Zhu Xiaotong was not convinced.

"I'm fine, but I'm afraid she's just as ...... as you," Lu Yang said with a smile.

Zhu Xiaotong blushed and glanced at Lu Yang, she herself is indeed a negative teaching material. In terms of ability, Zhu Xiaotong has absolutely no problem taking over Zhu Guangzhi's class, but she is not here, and Zhu Guangzhi is reluctant.

What makes Zhu Guangzhi quite pleased is that although his daughter cannot take over, she married a good son-in-law, and when he is old in the future, Zhiyuan Real Estate will finally be able to pass it on and not decline.

"Don't disturb me and my baby listening to music." Zhu Xiaotong pushed Lu Yang and diverted the topic.

Lu Yang got up and said: "What's so good about this song, the level of the performer is very average, and he is not qualified to give my child prenatal education...... Today, I will personally go out and play a song for the child and the child's mother, so that you can listen to what is Chinese classical music! ”

Lu Yang didn't let off the cannon, he walked into the study and took out a flute. To be honest, after listening to music all morning, he really had a bit of an itchy hand. In any case, Lu Yang is also a professional-level performer, and this skill has not been shown a few times until now, which is indeed a pity.

Zhu Xiaotong looked at Lu Yang with a smile, she knew that her lover had a lot of attainments in some Chinese classical musical instruments, but she really didn't listen to him play a few times.

Holding the flute in his hand, Lu Yang's temperament changed suddenly, and after that, the melodious flute sound came out, which made Zhu Xiaotong, who rarely appreciates this kind of music, feel amazing.

In Zhu Xiaotong's admiring gaze, Lu Yang finished blowing a song "Gusu Xing" and won Zhu Xiaotong's applause.

"Husband, I didn't expect you to have this skill." Zhu Xiaotong praised.

Lu Yang snorted: "Your husband has a lot of abilities, flute, guzheng, guqin, xiao, erhu, gourd silk, qiang flute...... Chinese classical musical instruments, I can play everything! ”

"That's great, I won't listen to CDs in the future, and you will play them live...... You just work hard, and when the baby is born, I will definitely love you more. Zhu Xiaotong clapped his hands and made a decision.

Lu Yang had a bitter face and was speechless for a long time, of course he was willing to give the child prenatal education, but now there are still more than three months before the child is born. Moreover, Zhu Xiaotong attaches great importance to prenatal education, and the time of prenatal education is also long, often half a day. Let Lu Yang play alone during this time, how can he stand it.

Realizing the arduous task of this task, Lu Yang began to persuade Zhu Xiaotong bitterly, asking her if she could use the recording she played for prenatal education. Lu Yang promised that he would record all the repertoire he could play for Zhu Xiaotong to choose prenatal education materials.

Under Lu Yang's various assurances, Zhu Xiaotong finally agreed, which made him feel relieved, and at the same time secretly warned himself that he would never be able to show off again in the future.

In July, Ye Wenbing brought Lu Yang good news.

After more than three years of hard work, in the domestic search engine market, omniscient search has finally surpassed thousands of degrees and ascended to the first place. For this result, although many people have expected it from the beginning, when this day really comes, it still makes people in a trance: Qiandu, who once searched in Chinese, finally failed.

There are many reasons for Qiandu's defeat to omniscience, and the most important reason is that he is technically defeated. As a global leader in intelligent search engines, Omniscient Search has continuously launched more efficient search technology in the past four years, and it is enough to throw off a thousand streets in terms of accuracy and experience.

Regarding technological innovation, Qiandu has actually been going on, and Li Yanhong has presided over many plans, including the "smart frame". However, in the past few years, Qiandu has invested a lot in research and development, and the technology has been improving, but the technical gap with omniscient search is getting bigger and bigger, which makes people bitter and helpless.
