As soon as Zhang Wenkai got up today, he received a call from Ye Jialiang, saying that the graphene battery had been successfully developed, and the sample had been produced and was being tested.

Zhang Wenkai, who heard the news, was very happy, the graphene battery was developed, I don't know how the performance of the battery is?

I didn't have time to eat, so I went downstairs directly, and Zhang Long and others were already waiting for me downstairs.

The Audi had been repaired and there was no sign of any damage.

When I opened the car door, I just saw Ning Yu's head probe looking around, Zhang Wenkai's head almost collided with Ning Yu's head, but fortunately, Zhang Wenkai reacted quickly and stopped entering the car.

Ning Yu's face also flushed.

Since Ning Yu was arranged by Zhou Yuya to his side, Ning Yu also followed Zhou Yuya's way, and went downstairs to Zhang Wenkai's house every day to wait for Zhang Wenkai.

After getting into the car, Ning Yu stretched out his hand and handed Zhang Wenkai a document and said, "This is an invitation letter from Zhongxing, I hope you can accept their invitation." ”

Zhang Wenkai took the invitation letter, flipped through it briefly, and then asked Ning Yu, "This is the first time you have sent an invitation letter?" ”

Zhang Wenkai has received a lot of invitations like this, basically some domestic manufacturers invite him to their company to negotiate wireless charger orders.

Ning Yu hesitated for a moment and said, "Since I took office, this is the fourth invitation letter issued by Zhongxing, and Sister Zhou received three invitations when she was in office before. ”

Of course, to explain these things clearly, Ning Yu's hesitation was to say whether to say the invitation that Zhou Yuya handled, but in the end he chose to say it, after all, the work must be explained clearly, which involves the boss's decision-making.

Zhang Wenkai nodded, returned the invitation to Ning Yu and said, "Take back the company for the record, I don't have time for the time being." ”

In fact, there is still time, but Zhang Wenkai really doesn't want to go, and he doesn't even want to send people, because he has given them a chance, but they didn't seize it, who is to blame?

Zhang Wenkai remembers very well that at the beginning, he asked various mobile phone manufacturers to sign the authorization plan of the mobile phone smart butler, but Zhongxing refused to sign the authorization at that time, and then Zhang Wenkai did not sell wireless chargers to mobile phone manufacturers who did not sign the authorization plan.

Now that Zhongxing regrets it, he found himself again, and he agreed so easily, so what's the matter?

Zhang Wenkai didn't completely exclude Zhongxing, he just wanted to teach them a lesson, and when they knew that only by believing in themselves unconditionally, Zhang Wenkai would continue to open orders, after all, Zhang Wenkai did not blacklist any domestic company.

Ning Yu took the document, lowered his head, and stopped talking.

Zhang Wenkai glanced at Ning Yu, who was bowing his head, dressed in professional clothes, his original long hair was also coiled up, and he happened to see the long eyelashes curled up slightly from the side, the petite little Qiong's nose, and the pink lips were glowing with charming color.

And although Ning Yu lowered his head, he seemed to know that Zhang Wenkai was really watching him, and his ears were slightly red.

"How is your sister now?" Zhang Wenkai also realized that he couldn't stare at people like this, and Ning Yu's personality was also a little introverted.

Ning Yu raised his head, put one hand on his chest, and said to Zhang Wenkai: "The condition has been controlled, and my mother said that she has found a suitable match in the Huaxia bone marrow bank." ”

Even if Zhang Wenkai doesn't know anything about this, he also knows some common sense, in the case of bone marrow transplantation, the matching of parents or siblings is the easiest to succeed, and how did Ning Yu's sister go to the Huaxia bone marrow bank to match? Ning Yu should be the most suitable!

Thinking of this, Zhang Wenkai also asked the question in his heart, "Ning Yu, don't you match your sister's match?" ”

Ning Yu did not answer Zhang Wenkai's words, but lowered his head again, his mood was a little low, and soon after, Ning Yu slowly spoke: "My sister is an adopted orphan. ”

Hearing Ning Yu's words, Zhang Wenkai was a little surprised, but he still nodded, and stopped talking, it is better to ask less questions about this kind of question, after all, this is something that people don't want to mention.

But Ning Yu didn't stop talking, but continued: "When I was eight years old, my parents adopted my sister. ”

Zhang Wenkai presents a picture in his heart, a kind couple adopted a weak little girl in an orphanage, and gave the little girl a home and an older sister, which is a very touching picture.

"But last year, my sister was diagnosed with leukemia." Ning Yu said, his eyes moistened a little.

Zhang Wenkai stretched out his hand and patted Ning Yu's shoulder, and said to Ning Yu with a smile: "It's going to be fine, haven't you already found a match!" I've got all the follow-up treatments. ”

The only place where Zhang Wenkai can help her is the unbearable medical expenses, and other places can't help her.

"Hmmm! Thank you very much to the owner, I will work here and pay for the medical bills. Ning Yu wiped away the tears from the corners of her eyes and said seriously to Zhang Wenkai.

Zhang Wenkai didn't say anything, just patted Ning Yu's shoulder again comfortingly.

Zhang Wenkai doesn't plan to let Ning Yu repay this money, and if he does good deeds, he has to repay it to others, which is a good thing, and he also has this ability, if he doesn't do it if he has the ability, what will the world become.

The car drove smoothly without a trace of bumps, and drove directly to the door of the public laboratory building.

The group got out of the car and went directly to the laboratory building, and after complicated verification and security checks, they finally came to Ye Jialiang's laboratory.

And Huo Yong stood at the door of the laboratory, and Zhang Long and Ning Yu followed Zhang Wenkai into Ye Jialiang's laboratory.

As a hired bodyguard, Huo Yong can still correct his identity, there are some things that the employer does not need to say, he should notice that when some secrets are involved, Huo Yong will take a few steps back.

At this time, Ye Jialiang was wearing a white coat, his hair was puffed out, his glasses were also covered with a layer of dust, his eyes were also dull, and his face was dull.

"Greedy for a job?" Zhang Wenkai looked at Ye Guokun and asked.

Ye Guokun didn't pay attention to Zhang Wenkai's question, but took Zhang Wenkai's arm, walked to the test bench, pointed to more than a dozen batteries and said:

"This is the graphene battery that is produced."

Zhang Wenkai set his eyes on the battery, which is much thinner than the previous battery, only about half the thickness of the USB port, and the size is only half the size of a bank card.

"How long does it take to charge a single charge?" Zhang Wenkai looked at the battery and asked.

Ye Jialiang said without hesitation: "It's about three times that of ordinary lithium batteries." ”

Zhang Wenkai was stunned, it was only three times, and the effect was not very obvious.

But Ye Jialiang's next words shocked Zhang Wenkai.

"However, it only takes three minutes to recharge." A burst of light appeared in Ye Jialiang's eyes.

What the? Three minutes, better than the performance I expected, after all, the technology is theoretically conservatively estimated to be charged for ten minutes.

"At the same time, it is safer and more stable than ordinary lithium batteries." Ye Jialiang said with some fanaticism.

If it is three times that of ordinary lithium batteries, the use time of the mobile phone is three times that of ordinary lithium battery mobile phones, and the mobile phone can only be used for one day, but after using graphene batteries, it can be used for three days.

What ultra-long standby or something is weakly exploded, compared with graphene batteries, the difference is 108,000 miles.

Besides, the charging time is only three minutes, what does that mean, the phone is fully charged, even if the battery capacity is very average, but it can be fully charged in such a short time, what is it like.

Normally, people have to care about the problem of mobile phone charging every day, once they forget to charge, they may delay a lot of work, but their own graphene battery completely solves this problem, and people no longer have to care about the problem of charging.

If it is combined with a wireless charger, it is basically where to go and where to charge.

Even some mobile phone parties can be turned on for 20 hours, or even 24 hours a day to play games, hang up, whatever you want. Imagine that when your phone is out of battery, you only need to find a power jack, charge it for three minutes, and the phone is full again, and you can chat and fart again.

"How's his lifespan?" Zhang Wenkai asked the question that worried about him.

If this battery doesn't last for a few days, it doesn't mean so much.

"After our testing, the service life is twice that of ordinary lithium batteries." Ye Jialiang pushed his glasses and said.

After the initial shock, Zhang Wenkai has now completely calmed down.

Nodding, he looked at the graphene battery seriously and asked the last question: "How much does it cost?" ”

Ye Jialiang turned around and took out a book and calculated.

Zhang Wenkai saw that Ye Jialiang made a list, what battery cells, protection boards or something, anyway, there are a lot of them.

"A little more than forty-five dollars." Ye Jialiang said with a gesture with his hand.

Forty-five yuan is still a bit expensive, after all, ordinary lithium batteries cost about ten yuan, but this price is also worthy of his performance.

Zhang Wenkai turned his head to Ning Yu and said, "You and Ye Jialiang prepare technical information. ”

Hearing Zhang Wenkai's instructions, Ning Yu was a little puzzled, and didn't know what Zhang Wenkai asked him to prepare the materials for.

"I'm going to patent this technology." Zhang Wenkai said slowly.

Applying for a patent means fully disclosing the technical theory and production method to the world, and if other companies use this technology to make a profit, they need Zhang Wenkai's authorization, but some scientific research institutions do not need to pay Zhang Wenkai any fees for research and use, nor do they need to authorize.

For the disclosure of technical information, Zhang Wenkai has his own plan, this technology only needs a few years to be cracked, if you do not apply for a patent, if someone cracks, your own loss will be great.

At the very least, if you apply for a patent, you have at least 20 years of patent rights.

Ning Yu nodded, and sorted out the technical information.
