Thinking about this, Jiang Hongwei's heart was touched, and he and Ji Bing glanced at each other, and their hearts were a little touched.

Just like traveling and shopping in Japan during this time, countless Chinese people say "I will donate a month's salary to fight the United States, and I will donate a life to fight the Japanese invaders", but when traveling, they ran faster than anyone else.

There are too many high-sounding words, and not many people really care about and really believe it.

It is really touching that this young man in front of him, who is only in his early twenties, can really do this!

"Well, that's it!" Jiang Hongwei nodded, "I have a heavy task over there, I choose to send two people over, and I will trouble you." Ji Bing, what about you? ”

"I'll pick someone first!" Ji Bing thought for a while and said: "Although we often assess this aspect of politics, we still need to be cautious at such a critical time. ”

Lin Dong said with a smile: "That's fine, lest I can't teach it all of a sudden!" By the way, I don't care about the room and board expenses, you can reimburse it yourself! ”

Jiang Hongwei and Ji Bing both laughed, and they could see that Lin Dong was joking. From the time Lin Dong said that the training was free just now, they could experience the kind of gratuitous kindness from Lin Dong's attitude, and the relationship between them instantly became much closer, a bit like a comrade-in-arms working hard in the same trench. It's not about how much the training costs, it's about that attitude that makes them feel close, after all, they're the same kind of people.

He Dongcheng interjected on the side: "Third child, I will also learn, how about it?" ”

"Okay!" Lin Dong nodded: "I am naturally welcome to learn from you, you must be responsible for the management during this time, and it is still necessary to understand a little principle." ”

After chatting for a while, making an appointment for training, Ji Bing and Jiang Hongwei left. Lin Dong saw that it was okay for a short time, so he began to tell He Dongcheng about his own programming method.

Early the next morning, Lin Dong got up and had a simple breakfast and went directly to the research institute.

Zheng Hong called last night and told Lin Dong something, and Lin Dong thought it was necessary for him to go and see.

When I arrived at the door of the real yàn room, I heard Zheng Hong and another person discussing something inside.

"Professor Zheng, how promising do you think our battery is? I've been watching the news all this time, why do I feel a little pessimistic? ”

Lin Dong heard that this was a graduate student led by Zheng Hong, Ye Tianlong from the Department of Physics of Haida University, who followed Zheng Hong to make high-energy batteries.

"How do you say that?" Zheng Hong's voice rang out, "What rumors have you heard again?" ”

"It's not a rumor." Ye Tianlong's voice was a little listless, "Our battery is still in the real stage, although this period of time has made rapid progress, but I think of the practical stage still needs to go a long way, and now several major international automobile companies have begun to increase investment in electric vehicles, I am afraid that when we are almost researched, people's high-energy batteries are in the car all over the world!" ”

"Xiaoye, don't be so pessimistic!" Zheng Hong was not affected by Ye Tianlong, and said with a smile: "You have also seen that our real yàn has been very smooth recently. The idea provided by Lin Dong is very correct, and our practical materials are sufficient, as long as this stage of practical research is completed, we can conduct practical research! ”

When Lin Dong heard this, he knocked on the door, walked in, and said with a smile: "Yes, as long as we have the correct number of real yàn and accumulate to a certain extent, we can transfer to the practical yàn stage, and we don't have to worry about this aspect at all." Besides, we only produce batteries, not cars, and even we only need to authorize patents, we don't even need to produce, we can rely on technology to eat! ”

As soon as Lin Dong came in, Zheng Hong and Ye Tianlong, who were sitting at the real table, both stood up. After Zheng Hong listened to Lin Dong's words, he thought it was true: "That's right, if we engage in technical research, we have to rely on technology to eat." As long as you have advanced technology in your own hands, you don't have to be afraid of other people's competition at all, Xiaoye, you are a little worried! ”

Ye Tianlong's face flushed slightly, and he didn't speak again.

Originally, Ye Tianlong still had some opinions about Lin Dong, he initially thought that Lin Dong was the kind of hot-headed second generation, and wanted to invest, and directly invested money after inspecting a project, but after Lin Dong communicated with Zheng Hong and other researchers last time, his opinion of Lin Dong immediately changed, in Ye Tianlong's opinion, only those words, if he didn't know in advance, he wouldn't have imagined that Lin Dong was actually a history department!

I'm very professional in physics!

Zheng Hong didn't pay attention to Ye Tianlong's expression, he said to Lin Dong: "Calling you over, it's the next research idea that needs to be sorted out." You are the funder of the real yàn room, and this must be decided by you. ”

In fact, since Lin Dong's small "exposure" last time, Zheng Hong has become aware of Lin Dong's opinions. In Zheng Hong's opinion, there must be a master behind Lin Dong, otherwise it would be impossible to grasp the essence of his reality so accurately.

He is different from Ye Tianlong, he can see that Lin Dong has a very clear idea of the development direction of high-energy batteries. Even better than he is in some ways. With Lin Dong's foundation, even if he is a genius, it is unlikely that he will be able to study these contents thoroughly, and someone will inevitably guide him in the back.

Zheng Hong has no resistance to this, as long as it is beneficial to this research, as long as it can put this research into civilian use and transform it into huge social and economic benefits, he will be satisfied.

Besides, the treatment given by Lin Dong is not low now.

"What are the differences?" Lin Dong was also not modest, and asked directly, "In which direction are you going to develop?" ”

"There are two paths to battery research now, you know." "One is to use the surplus nuclear energy from nuclear waste to develop high-energy batteries, and the other is to use rare earth metals and graphene to make supercapacitor batteries," Zheng said. We have made key breakthroughs in both areas, and no matter which direction we go, we will see results in the short term, so we need to make a decision now. ”

"What about your opinion?" Lin Dong asked rhetorically, he knew that if he needed to decide at this time, it should be that there was a disagreement within the real room.

"My opinion is leaning towards using nuclear waste as a feedstock." Zheng Hong said: "Although nuclear waste is rarely accessed by ordinary people, it is not impossible to find it, and it is a good way to turn waste into treasure." I believe that the state will support it, and then we will even be able to buy nuclear waste from other countries at a low price and use it. ”

"However, the cost is relatively high." Ye Tianlong interjected, "Nuclear waste has radiation, so it will be dangerous to deal with it, after making a battery, it is also necessary to protect the slow-release energy of raw materials, the protective layer is thick, the battery head is relatively large, and the cost is relatively high." ”

"How about making supercapacitor batteries out of rare earths and graphene?" Although Lin Dong knew it in his heart, he still asked.

"It's cheap." Zheng Hong and Ye Tianlong both said, and then Zheng Hong said; "The only drawback is that although the battery life is much longer than that of today's ordinary batteries, there is still a big gap compared to nuclear treatment batteries!"

"How big of a gap?"

"Nuclear treatment batteries are used in ordinary family cars, and they can run 5,000 kilometers without recharging!" Zheng Hong was a little excited, "It's just that the cost price is more expensive." It takes about 200,000 or so. And the supercapacitor battery can allow an ordinary family car to run a thousand kilometers in a row, and the charging speed is also very fast, and it only takes less than an hour to fully charge! The cost price is about 10,000 yuan. ”

"Then why not develop both?" Lin Dong smiled: "You only need to target different customers." Why do you have to get rid of one of them? ”

ps: In this chapter, the dragon brother Ye Tianlong, a technical man, will appear in the future.
