The strongest krypton gold system

After finishing all this, Yu Chengdong breathed a sigh of relief, with a relaxed smile on his face. Seeing Wang Lin sitting on the sofa, he had a confident expression on his face, thinking that he would not be aimless, I am also full of hope for this lithium battery!

It is a relatively long process to test lithium batteries in the laboratory. It is to remove some test items that take a long time, and it will take a long time. He said with some embarrassment:
"I'm sorry, this lithium battery is really important to Huawei, so please wait here for a while!"

"It's okay!"

Since you want to sell things, it's still such an order, you always need someone to inspect the goods, otherwise how can you rest assured!
Wang Lin is very patient about this, he can wait for a few hours, even a few days!
A few days in exchange for a large order of billions, this deal is really worth it, there is nothing more cost-effective than this!
When Yu Chengdong saw him, it was not as simple as what he said verbally, and there was no trace of impatience on his face. It is really not easy to have such a kung fu of self-cultivation at a young age!
In the following time, the two chatted a lot, from the history of mobile phone development in the past, to the current smart phone, and the prospect of future technological development, there are still many common topics between the two of them!
Time passed slowly in the chat, and three hours passed in the blink of an eye!

Yu Chengdong glanced at the dial on his wrist and found that more than three hours had passed, but the phone hadn't moved at all. It seemed that there should be no news yet, which made him a little anxious!
Wang Lin was not in a hurry, and benefited a lot from the chat, and wanted to have a good talk. Seeing his anxious expression, he comforted him in turn:

"Mr. Yu doesn't need to be so anxious. This is a job that is done slowly and meticulously. We just wait quietly, and the result will always come out."

Others comforted him in turn, making Yu Chengdong a little ashamed, but he felt that what he said made sense, took a deep breath to calm down, and quietly waited for the result!

But at this moment, the door of his office was suddenly pushed open, and a middle-aged man in a white coat recklessly broke in, ran up to Yu Chengdong briskly, and asked quickly :
"Where did you get this lithium battery?"

Yu Chengdong has long been accustomed to these behaviors of his, and there is no look of anger on his face. Seeing him coming over and guessing that the test results should come out, a gleam of joy appeared on his face!
So he took the initiative to introduce Wang Lin beside him, and said with a smile:

"This lithium battery was brought by Mr. Wang. Their company specializes in the production of batteries and is an expert in this field. They only authorized this patent to Umicore International some time ago!"

The engineer here is named Chang Yuan. Although he is only 36 years old this year, he is still relatively young, but he is already an expert in Huawei's battery project!

He quickly looked at Wang Lin who was next to He Bi, and found that he was really young. He heard that he had applied for a patent for this battery technology and authorized the patent for foreign markets to Umicore, and he was immediately in awe!

He knows Umicore very well. He once practiced there for a period of time and knows that it is the world's largest manufacturer of lithium-ion batteries. It is not easy for them to seek patent authorization in person!
The data obtained in the laboratory just now also surprised him very much. Now that he saw the Lord, he was a little excited immediately!
Chang Yuan took a step forward, took the initiative to hold Wang Lin's hand, and said affectionately:
"Mr. Wang is really young and vigorous, and has solved this worldwide problem. First of all, on behalf of the country, I thank you!"

Wang Lin was a little confused by him, and only then did he react, broke away from his handshake, smiled and said indifferently:

"Thank you for your compliment, it's not as serious as you said, this is one of my original intentions!"

Seeing that he is so humble, Chang Yuan is helpless, but one thing he himself knows is that the difficulty is very great!

You must know that lithium-ion batteries appeared more than ten years ago, but now they are still using lithium-ion batteries. The speed of battery upgrades is very slow, so you can know the difficulty!

There are also international giants who have fallen in love with this piece of cake in this field, but have invested billions of funds to get nothing, all in vain!

Yu Chengdong saw the boss in the laboratory come out, and he was very concerned about the battery data at this time, so he asked anxiously:
"How about the data of this lithium battery?"

"The data of the lithium battery is very good, how good is it? The energy density of the battery has reached 500wh/kg, and the capacity is a real 6000mAh!

In addition, the life of the battery has only been checked for a period of time, but according to the attenuation curve of its life, the expected life is about 800 times, and the more accurate test depends on the laboratory! "

Speaking of the data of the battery test, Chang Yuan began to talk freely, completely ignoring Yu Chengdong who kept winking beside him!

After talking about the data, he came to his senses, pointed at Yu Chengdong's eyelids and said with concern:
"Mr. Yu, your eyelids twitched so violently just now, why don't you go to the hospital?"

Although Yu Chengdong knew that he had good intentions, but just now he completely ignored his eyes and completely disrupted his steps, he was still a little angry, so he gave him a hard look!
Then he smiled wryly, and said helplessly:

"It's okay, you can go now!"

"Oh!"

Chang Yuan still had something to say to Wang Lin, but he was not very happy to see Mr. Yu. Knowing that he should disappear before his eyes at this time, he had no choice but to leave!
Wang Lin was watching the incident between the two of them, and almost couldn't help laughing. If he was not afraid that he would misunderstand, he should have laughed out loud, but he endured the pain, and he pinched his thigh purple!

After Yu Chengdong saw Chang Yuan left, he felt much better. With a smile on his face, he said warmly to him:
"Since the data of the lithium battery is so good, our Huawei company has decided to officially adopt it, but Mr. Wang needs to take good care of the next price!"

"Good talk good talk!"

The next step is the main event. It concerns the core interests of the two companies. Wang Lin didn't dare to be careless, so he cheered up and said:

"Then I'll cut to the chase and tell you the price of lithium batteries!
The price of the 6000mAh battery is 129 yuan, and the 8000mAh battery is 169 yuan! "

After hearing the price, Yu Chengdong let out a sigh of relief. This price is not too expensive, it is not beyond his imagination, and he has already approved this price in his heart!

The two sides negotiated together on the price, then the next step will be much better, and the agreement will be reached directly!
