When Jian Pengfei met Cao Zhenhai, the latter was writing a report in his office.

After learning of his intention, Cao Zhenhai shook his head with a smile: "Mr. Jian, I'm very sorry, thank you for lifting up and valuing me, but I've been completely disappointed with the lithium-air battery, so please go back." ”

Jian Pengfei frowned and said: "Academician Cao, before I came to you, I had already visited many experts in the battery industry, but they had almost the same attitude as you, and they all rejected me as soon as they heard about the lithium-air battery.

I want to know, why are you so optimistic about lithium-air batteries, it is supported by theory, right?"

Cao Zhenhai opened the thermos cup and drank some water, and said slowly: "Lithium-air battery...... A beautiful vision.

There are many companies that have played lithium-air battery technology, including domestic and foreign battery energy giants, after all, the theoretical energy density of lithium-air batteries is too high.

But in the end, they all failed, without exception. ”

Cao Zhenhai said: "There are many problems and difficulties in lithium-air batteries, and lithium crystal branches are a hurdle that cannot be bypassed, and there are huge safety hazards in the battery before it is not solved.

In addition, there are a lot of side reactions in the battery, which cannot be solved, and it is meaningless to make a lithium-empty battery.

Anyway, I can't gnaw on the hard bone of lithium-air batteries, and I don't plan to touch them. ”

Jian Pengfei persuaded again and again, even if he offered a high salary, Cao Zhenhai still shook his head and did not agree, helplessly, Jian Pengfei sighed in his heart and was ready to leave.

But before he left, Cao Zhenhai stopped him: "You wait first." ”

"Academician Cao, have you changed your mind?"

"No, I didn't change my mind, I just remembered something. Cao Zhenhai hesitated for a moment and said: "I have no interest in lithium-air batteries, but I can recommend a friend who has a persistent belief in lithium-air batteries to you."

Although his resume is average, his practical ability is not bad, and he is suitable for working in your company.

And, even if the world says that lithium-air batteries are not good, he will definitely be an exception. ”

Jian Pengfei's eyes lit up slightly: "Then thank you so much!"

......

In the evening, He Tianqiang dragged his tired body back home from work, collapsed on the sofa and closed his eyes to rest.

He Tianqiang, 46, works at a lithium battery research institute in Yanjing.

As a supporter of the lithium-air battery theory, but doing research work on lithium-ion batteries all day long, He Tianqiang felt very tired and uncomfortable.

But there is no way, now the lithium empty battery is already considered by the industry to be an impossible technology, although he supports the theory of lithium empty battery, but he does not dare to blatantly study, can only be fine, in some academic forums to post articles, express their optimism about lithium empty battery technology.

"Alas, when is this kind of day the end......" He Tianqiang opened his eyes and rubbed his eyebrows, the look in his eyes was a little sluggish.

At this time, his wife, who was cooking in the kitchen, came to the living room, sat next to He Tianqiang, patted his thigh and asked, "Lao He, let me tell you something." ”

"Well, let's talk about it. He Tianqiang nodded, sat upright, and took a sip of the tea on the table.

The wife said: "Our kid has a girlfriend, I am more satisfied with the girl, I think they should be able to get together, so this son is about to get married, and I think it is time to put the matter of buying a house on the agenda." ”

"Buying a house......" He Tianqiang muttered, in his impression, the housing prices in Yanjing are unattainable.

The wife said: "I went to a sales center this morning and found a house with a good location and affordable price, and the down payment is about 2.75 million." ”

"2.75 million...... Do you have enough money at home?"

"It's just not enough, it's still 800,000 short. ”

He Tianqiang heard that his head hurt a little, but as the head of the family, his son wants to get married and buy a house, so he can't be weak and say no, right?

So, He Tianqiang had no choice but to force his cheeks and say: "I'll figure out a way to deal with money......"

His wife saw his reluctance at a glance, and pouted: "What can you do? Your annual salary of 300,000 yuan, after removing expenses such as food and drink, it will take at least three or four years to make up enough for 800,000 yuan, and by that time, the house price will definitely rise again."

What I think is, if it really can't be done, we will sell the house we live in now, and then go to live in your dormitory, and use the money to buy a house for our son, what do you think?"

He Tianqiang smiled bitterly: "I don't care, it's the same wherever I live, I'm afraid that kid doesn't agree, you don't know his character, you have to be strong." ”

Wife: "It's up to us to do things or not, it's another thing if he agrees, and when the matter is settled, he can't agree with it." ”

He Tianqiang sighed: "Okay, then you can handle this matter." ”

At a certain moment, He Tianqiang felt that this person was really tired of living.

People like him have been revolving around the house all their lives, when they were young, their parents bought a house, when they grew up, they wanted to buy a house, and when they were older, their son wanted to buy a house.

For most of his life, he has been making wedding dresses for the house and becoming a real house slave, but he has to do it, which makes people helpless and sad at the same time.

Jingle dong, jingle dong......

At this moment, the doorbell at the door suddenly rang, this doorbell is connected to the downstairs access control system, it rings often, it is estimated that the neighbor's person pressed the wrong one, so He Tianqiang's wife walked to the door, closed the bell, and opened the door downstairs at the same time.

However, it didn't take long for a knock at the door.

He Tianqiang: "Who is it?"

He Tianqiang's wife replied: "I don't know, I thought it was a neighbor's person downstairs just now." ”

As she spoke, she quickly walked to the door and opened the door, only to see a man in a suit, standing upright at the door, seeing her smile and asking, "Excuse me, is this Professor He Tianqianghe's house?"

"Yes, you are?"

"My name is Jian Pengfei, from the Black Bone Group, introduced by Academician Cao Zhenhai, I came to find Professor He, I want to talk to him about some battery matters, I don't know if Professor He is at home?"

"Yes, don't stand outside, please come in. He Tianqiang's wife answered, and shouted to the living room: "Lao He, looking for you." ”

After Jian Pengfei entered He's house, He Tianqiang's wife hurriedly went to pour water, while Jian Pengfei sat on the sofa and chatted with He Tianqiang.

After Jian Pengfei finished introducing himself, He Tianqiang asked, "Mr. Jian, don't you know what you have to do with me?"

Jian Pengfei said: "That's right, because our company plans to carry out research in the field of batteries, focusing on lithium-air batteries, so our boss sent me to find relevant professionals."

I went to Academician Cao Zhenhai before, but he was rejected by his old man, but he recommended you to me, Professor He.

Therefore, I hurriedly came to visit you according to the address given by Academician Cao. ”
