Zhang Lan thought about it, whether it is a nuclear fission battery or a controllable nuclear fusion battery that represents the future development direction of nuclear batteries, this thing does make people feel comparative, well, dangerous, if the car equipped with these two batteries accidentally has a serious car accident on the road, it will affect the nuclear battery as the power core of the vehicle...... Thinking of this, Zhang Lan couldn't help but shudder: Damn, the power is definitely no less than a small nuclear explosion! It is estimated that there is nothing alive within a radius of one kilometer, and as for radioactive nuclear contamination, it is not known that it will not be cleared until that year.

"Then since you can't build nuclear batteries, can you build fuel cells or lithium-ion batteries?" After thinking about it for a long time, Zhang Lan finally thought of these two alternative products for nuclear batteries

"Fuel cells and lithium-ion batteries?" Cage's frowning brows still didn't soothe, but the words he said made Zhang Lan feel that this guy was quite underwhelmed, "This kind of thing that we don't know how many centuries we have eliminated is really a bit difficult to study." ”

"Is it difficult to have trouble with nuclear batteries?" Zhang Lanqiang resisted the urge to step forward and beat this guy up - in fact, he was still worried that he didn't feel anything if his hand hurt, "It's like asking the current pumping machine design experts to copy an ancient waterwheel, there shouldn't be any difficulty, right?" ”

"It's not like this," Cage smiled bitterly, "For these pumping experts, at least they know the structure of the ancient waterwheel, and it is naturally easy to set the level of fuel cells and lithium-ion batteries on our planet Cybers, just like the current people on your earth know about the living habits of ancient people tens of thousands of years ago, almost ignorance." What does this make us do? ”

"Is it that hard?" Zhang Lan was obviously skeptical of Cage's words, and thought that this guy was suspected of shirking responsibility, "Why don't you learn from the existing fuel cell technology and lithium-ion battery technology on our earth, and use your technology to improve it with the existing technology on our earth, shouldn't it be too difficult?" ”

"Your fuel cell and lithium-ion battery technology on Earth? That thing that looks like a super colander? Cage clutched his head in pain. If this is the case, it is not difficult to not only quickly realize the practical application of fuel cells and lithium-ion batteries, but also greatly increase their storage capacity while greatly reducing their costs. After a pause, Cage spread his hand with a helpless expression, "It's just that this is of little use to us, we can't let Arnold and these guys change the battery every few days."

"Who said it was going to be for you?" Zhang Lan, who finally couldn't hold back any longer, grabbed something in his hand angrily, and threw it at Cage no matter what it was. "You can do it with your own nuclear batteries. I asked you to make fuel cells and lithium-ion batteries, which are for the products of the Alice Group. For example, let's get a fuel cell that can be used for several months or a week, isn't it? ”

Normal use of a week without adding fuel to the car? If the price is not much different from the price of the same car, it is estimated that if the news spreads, the Alice Group will be on the front page of the world's major media.

"I see, why didn't you say it earlier?" Hearing Zhang Lan say this, Cage let out a long breath, "I wonder why you let us put a nuclear battery with a stronger endurance and don't use it." And with a fuel cell with only a little battery life, it turns out that this is the case! In that case, there is no problem

"What do you think I'm thinking? How demanding do you think I can be? Zhang Lan picked up the thing in his hand and knocked Cage on the head again, this time it was a plastic cup, which made Cage head bang, but Cage didn't seem to be aware of it, "I said from the beginning, I just asked you to make an energy source that can replace oil." ”

There was a pause. Zhang Lan added a point. "Yes. Finally, we came up with fuel cells and lithium-ion batteries. Whether it is the cost of production or the cost of use. The cost of the whole set of fuel cells plus stepper motors constitutes the ground power mechanism. It cannot be higher than the same power petroleum fuel engine; As for the cost of use. It has to be cheaper than using oil! Well. In the upfront costs can be slightly higher. This is conducive to the promotion of our products. Battery-based vehicles or lithium-ion batteries. Although there is no need to add fuel for a week. The cost of running for a week is several times more expensive than using gasoline! ”

"Don't worry." Cage said. "Such a simple thing. Well. It's just a bit old. It's not too difficult、This。 There are two types of batteries: fuel cells and lithium-ion batteries. Which are you going to use? I've seen your information on fuel cell sites on Earth when I'm idle. There are basically six types of fuel cell technologies: alkaline fuel cells, phosphate fuel cells, molten carbonate fuel cells, solid oxide fuel cells, and geohydrogen fuel cells using proton exchange membrane technology. It is commonly known as solid polymer fuel cells. The latest is also biofuel cells. In terms of the ground fuel cell technology that is now being used on your planet. The technology is relatively mature phosphate fuel cell. Now it has formed a certain scale. Technology has also advanced to a certain level. ”

"As for lithium-ion batteries." Cage, the guy paused in a pretentious manner. After finding plenty of pleasure in Zhang Lan's expectant gaze. That's when he began to continue with satisfaction. "It's so old that it can almost be called fossil-level technology. Well. Are you going to use it too? Now it seems that your earth-ground nickel-metal hydride batteries are more popular. It seems that the most land used now is nickel-metal hydride batteries. Why don't you also engage in nickel-metal hydride batteries? ”

"Of course." Zhang Lan squinted at Cage's ill-intentioned guy. "NiMH batteries are compared to lithium-ion batteries. Do you still need to say the advantages of lithium-ion batteries? Don't you understand? Want to fool me? ”

"Hey, hey." Didn't flicker successfully Cage. Rubbing his head and giggling.

"This. Say it. Of course, I know that the most mature technology is phosphate fuel cells. However, such fuel cells seem to be mainly used in power stations or in power supply units that do not need to be constantly moved. It is not suitable for use in cars. Several other battery dialects. How do you think that using proton exchange membrane technology for geohydrogen fuel cells compares to biofuel cells. Which is better? Which place costs less? "Zhang Lan only has a general understanding of these things. The specifics are almost incomprehensible. "Lithium-ion batteries go without saying. Although nickel-metal hydride batteries are commonly used in mobile phones nowadays. But a few years later, mobile phones will basically use lithium-ion batteries. As a person who is reborn from the future. How could you not understand this? A few more years. Many of the more high-tech electric vehicles with an experimental nature. The batteries used are also lithium-ion batteries. instead of the original traditional lead-acid battery. Later, the electric bicycle industry developed in China. Finally, there are also products that use lithium-ion batteries. ,

Now the only restriction on the development of lithium-ion batteries, one is that the technology is still a little immature, and the other is because the production cost is too high, which limits the use of lithium-ion batteries, but this problem, if you don't solve it, someone will solve it in a few years.

The reason why Zhang Lan set his sights on the fuel cell is really because this thing is a real baby bump: the conversion efficiency between fuel and electricity in the fuel cell system is surprisingly high, between 45% and 60%! The efficiency of thermal power generation and nuclear power is about 30% to 40%.

Not only because of the high energy conversion efficiency of fuel cells, but also compared with thermal power and nuclear power, the use of fuel cell power generation equipment has a low degree of environmental pollution, and the latest hydrogen fuel cells can already achieve no pollution; In addition, the fuel cell power station occupies a small area, the construction period is short, and the power of the power station can be assembled by the battery stack according to the need, which is very convenient. Fuel cells are very suitable for centralized power stations or distributed electricity, or as independent power stations for communities, factories and large buildings. In addition, fuel cells have one of the biggest advantages over traditional power supply methods: fast load response and high operating quality. From this point of view, fuel cells are one of the ideal clean energy sources in the future.

To be honest, although China's research on fuel cells is not in the world's most advanced ranks, it is not too backward, but compared with Europe, the United States and Japan, the technology in this area is still lagging behind, especially in the research and manufacture of the most important ion membrane on the fuel cell, it has always been a blank, and the technology of fuel electronic membrane has been monopolized by Europe, America and Japan. It was not until 200 years that China made a breakthrough in fuel cell ion membrane technology, and thus entered the ranks of advanced countries in fuel cell technology.

It's just that China's research on fuel cells is very embarrassing: on the one hand, it has a place in the field of fuel cells in the world in terms of kilowatt-level low-power fuel cells, and even in some key technologies, it is not inferior to Europe, the United States, Japan and other countries, but in the field of large-scale million-kilowatt large-scale commercial fuel cell technology, China is almost still blank.

The development of large-scale fuel cells is a key research project in Daguo, and the business community has also invested heavily in the research and development of fuel cell technology, and has achieved many important results, making fuel cells will replace traditional generators and internal combustion engines and be widely used in power generation and automobiles.

Taking advantage of the fact that the fuel cell technology is not mature enough, Zhang Lan is naturally unwilling to miss such an excellent opportunity to control the direction of the world's energy development.
