I know a little about all aspects? I also said I know a little about all aspects of atomic bomb manufacturing, but what can this mean? Even if I prepare all the materials, I still can't create an atomic bomb...

So, Fu Song was not satisfied with Zheng Kun's answer at all and continued to ask: "What do you mean is that there are no available lithium batteries available yet?"

Zheng Kun smiled and shook his head, "You are not engaged in battery research, so you may not know much about it. This battery can be divided into primary batteries and secondary batteries according to whether it can be charged and discharged. For example, the commonly used flashlight dry battery in China is primary batteries, which are disposable and cannot be charged and discharged. The battery on cars is secondary batteries that can be charged and discharged. The research on lithium primary batteries began in the 1950s and was realized for military and civilian purposes in the 1970s. For example, the battery on electronic watches mentioned earlier belongs to lithium primary batteries."

Fu Song nodded, knowing that he had been in a misunderstanding. Whenever he mentioned lithium batteries, the only thing he thought of was the rechargeable and dischargeable lithium batteries on his mobile phone. As for the lithium-ion battery, the lithium-ion battery was directly ignored.

"When it comes to rechargeable and dischargeable lithium batteries, they are divided into lithium metal secondary batteries and lithium ion secondary batteries. The research on lithium metal secondary batteries was only about ten years later than the primary batteries and was launched in the early 1980s. However, due to safety issues, in addition to Israel Tadiran and Canadian HydroQuebec, now, the development of lithium metal secondary batteries is basically stagnant. Until now, lithium metal secondary batteries are only in laboratories, which are still far from real commercialization."

Fu Song said: "Does the electrode materials of these two lithium batteries have different electrode materials?"

Zheng Kun said: "Yes, the negative electrode of lithium metal secondary batteries is pure lithium metal, and the positive electrode material of lithium ion batteries is lithium ion oxide. I think the future development direction of lithium batteries is lithium ion batteries, which is more safe than lithium metal batteries. Like the Motorola mobile phones mentioned in your driver's hand, you can completely replace the nickel-cadmium battery with rechargeable and dischargeable lithium ion batteries. In this way, the size and weight of the mobile phone can be reduced by more than twice, and even cars can use lithium batteries as a power source."

Fu Song asked: "Is lithium-ion secondary batteries still good now?"

Zheng Kun explained: "Now there is a concept of 'rock chair-type batteries', which replaces lithium metal with embedded compounds. Both poles of the battery are acted as the embedded compounds. In this way, there is a 'space' on both sides for lithium ions to be embedded. During the charging and discharging cycle, lithium ions are 'embedded' and 'de-inserted' on the positive and negative electrodes, just like a rocking chair. However, if this concept is realized, there are three obstacles: one is to find a suitable lithium-embedded positive electrode material, the second is to find a suitable lithium-embedded negative electrode material, and the third is to find an electrolyte that can form a stable interface on the surface of the negative electrode..."

Seeing his son spitting, Old Mrs. Qiao coughed gently and said, "When you mention your work, you are like a different person. No one understands what you said. Eat! You are so proud, and you will be proud after you finish your meal."

Zheng Kun licked his lips with uneasy intentions and said to Fu Song: "Let's eat quickly, I'll talk to you carefully after you finish eating."

Fu Song was suddenly a little amused, but he nodded and said, "Okay, I'm very interested."

After dinner, Xiao Zhumei was pulled by old man Zheng again, and Fu Song was pulled by Zheng Kun to the balcony on the second floor, and drank tea while basking in the sun.

Fu Song looked at the blue bay in the distance and smiled and said, "No wonder you don't want to return to China. You can't see such a view when you sit at home in China."

Zheng Kun added tea to him and said, "You can't say anything, right? Do you want to bury me again?"

Fu Song was amused by him and said, "I really didn't do this time, I'm talking about my heart."

Zheng Kun sighed and said, "Don't think I've started a family and started a business in the United States, but I don't have a sense of belonging to it. If you don't say anything else, just talk about work. I have to work harder than those white people and even Indian colleagues. There is a saying in our Chinese circle that no matter how hard Chinese people work, they will eventually encounter an invisible ceiling, or glass ceiling."

Fu Song glanced at him and asked, "Then do you regret it now?"

Zheng Kun lowered his head and said after a while: "I'm going to tell you, I actually regret it now, really. But I am a person, I don't have much pursuit, and I'm content with such a life."

Fu Song shook his head and said, "You are wasting your talents."

Zheng Kun smiled self-deprecatingly and asked, "Then I won't waste my talents when I go back to China? My father said that the financial situation in China has not been very good in the past two years. In order to develop the economy, he even cut off scientific research funds. What do you think I can do when I go back? Like now, sitting in the office basking in the sun and drinking tea and reading newspapers?"

Fu Song choked by him all of a sudden and said with a wry smile: "Okay, I won't talk about this anymore. I'll ask you, are you sure to do the research and development of lithium batteries?"

Zheng Kun rolled his eyes and said, "You think I am Superman, how can I do it alone?"

Fu Song looked at him with bright eyes and said, "You are not alone, I will give you a laboratory. You will be in charge of R&D work. If you want money and people to give money, can you give me? "

Seeing his serious appearance, Zheng Kun couldn't help but wonder: "Who is right about this? Where can I find a laboratory?"

Fu Song said: "I am quite optimistic about lithium batteries. To be precise, lithium-ion rechargeable batteries. If you come to my place, you can discuss any conditions."

Zheng Kun became more and more confused as he heard it. He put down the teacup and smiled, "Go to your side? I don't even know what you are doing. Do you want me to go to your side?"

Fu Song handed him a business card and said, "Where is me, I have made some money in Xiangjiang for the past two years, and I can still take out two or three million."

"How many?" Zheng Kun shook his hand and his business card fell directly to the ground. Before he could pick it up, he stared at Fu Song straight at him, "I heard it right just now, did you? Two or three million? US dollars?"

Fu Song smiled and said, "If you don't think it's enough, I can squeeze out some more. What's the matter? Are you interested in coming to my place?"

Zheng Kun pinched his thighs hard, grinned and said with a wry smile: "I was a little scared, no, where did you get so much money?"

Fu Song spread his hands and said, "Didn't you say it? You earn it from trading foreign exchange and stocks."
