Chapter 972

For tanks

Hearing this strange question and looking at those solemn and eager eyes, Lu Zhou finally understood what director Lu had come to do.

In fact, the research on electric driven tank is nothing new.

As early as the 1930s, Dr. Porsche studied this subject.

The vk4501p tank with porschetype101 / 1 air-cooled engine is installed. The power generated by the engine is stored in the battery first, and then two 275kw motors are driven. Undoubtedly, it has met the basic characteristics of an electric driven tank.

However, due to the limitations of the times, this electric drive tank technology has not been able to play a great advantage in the battlefield, only the "differential steering system" design has been preserved.

In the next century, with the continuous progress of science and technology, the concept of electric drive tank has been repeatedly discussed.

As Lu Zhou can guess, director Lu asked this question not only to know if it could be used in tanks.

What he really wants to ask is whether the development dividend brought about by controllable nuclear fusion can spill over from the economic field to the military industry

"You have to ask the experts in the field of military industry," Lu Zhou answered after thinking for a moment, "but in my opinion, whether it's lithium sulfur battery or lithium air battery, the future in the field of military industry is limited."

As soon as director Lv heard this, he was in a hurry and asked.

"Why?"

"Security." Lu zhousighed and said, "as long as it is a chemical battery, it is basically based on the oxidation-reduction reaction to realize the conversion of electrical energy and chemical energy. Since it is redox reaction, there is great instability. Especially lithium, which can ignite spontaneously when put into the air, if it is hit by a shell or something, it is not as simple as oil leakage. Even if there is no chance to take emergency measures, it will be killed 100%. "

Someone should have told him about it.

However, according to the appearance of director Lv, it may be mentioned that someone did, but he didn't take it seriously.

“…… That's it. "

After hearing Lu Zhou's answer, director Lu's face showed a trace of regret.

Obviously, before we come here again, there should be a technical demonstration meeting on this topic in Shangjing. And in terms of the expression on his face, he should support the use of lithium-air batteries in the military industry.

Staring at the tea cup on the table and thinking for a long time, the old man still raised his head a little unwillingly and asked after him with no heart.

"Is there no room for improvement? For example, make a battery that can balance stability and high energy density? "

"I'm afraid that kind of thing you said can't be done by chemical batteries..."

Lu Zhou shook his head a little bit, didn't know what to say. After a pause, he continued.

"Actually I don't know much about military. However, if it's only based on my personal understanding, although it's not reliable to use lithium-air batteries in front-line combat units such as tanks, it should be feasible to use them in non front-line combat units such as transport vehicles, military trucks, and even transport helicopters to ease the dependence of logistics system on oil. "

Electric drive engine has a great advantage in noise, concealment and control.

Especially in the defense war, on the premise that the infrastructure can be guaranteed, the advantage of the logistics system electrification is still obvious.

As for the offensive war

China is a peace loving country, which will not be discussed for the moment.

Looking at Lu bureau chief's face, Lu Zhou continued with a smile.

"In fact, I am a pacifist. I don't have much research on weapons. But if my advice is needed for national defense construction, I can only say that it's better to find a way out from other places than chemical batteries."

Director Lu immediately asked, "where else?"

Lu Zhou nodded his head and continued: "for example, controllable fusion technology, now I have made miniaturized controllable fusion batteries. Although there are still many limitations such as high cost, there is always a process for scientific progress. As long as you keep the investment in this field, maybe in a decade or two, small fusion batteries will mature to the effect you imagine. "

Controllable fusion miniaturization technology has been used in a series of spacecraft, such as Xiangrui, Xiaguang, magpie bridge, etc. at present, a new generation of deep-sea nuclear submarine is said to be equipped with the same type of battery.

Lu Zhou remembered that he saw orders from the equipment procurement department of the Chinese navy on the account sheet of the space shuttle assembly center, and the number of purchases seemed not small.

Although there is still a long way to go to move this technology from the sky and sea to the land, and reduce the cost and minimum volume to an acceptable level, who will say the future?As long as we continue along this road, we will see the hope of realization one day.

……

The further miniaturization of fusion battery is the future, and no matter how Lu Zhou draws the cake of fusion battery to the second in charge of the Energy Bureau, the whole new energy automobile industry is going crazy by now.

The downstream supply chain is not bad. A few domestic new energy automobile factories called engineers to study the paper of Lu Zhou all night. From the wording of a few words, it can be inferred that although this kind of lithium-air battery should have little impact on them, it is only necessary to add a grille in front of the car.

Whether it is optimistic or not, or the real impact is not great, in short, the major new energy vehicle manufacturers are reluctantly relieved.

But it's a relief, but that doesn't mean they just let it go.

In view of the potential impact of uncertain factors on the new energy industry, byatty and other enterprises have postponed the new vehicles that were scheduled to be launched recently, and are ready to wait until the dust of lithium air battery technology settles before launching new models, and start to design new energy vehicles with air intake grilles that meet the expectation of "lithium air battery pool".

Although consumers generally have a wait-and-see mood, the overall impact on them is not significant due to the continuous decline in electricity prices and the steady progress of domestic oil prices.

However, these auto manufacturers are relieved, but for the midstream enterprises in the whole supply chain, especially those auto battery manufacturers, they are suffering a lot.

How many wait-and-see for two years, finally determined to complete the upgrading of the production line of the boss, can be said to be overnight worried about the white hair.

It's true that the new energy industry is becoming more and more popular, but their products are being eliminated

Zhongshan new material warehouse.

Looking at the pile of lithium sulfur batteries in the distance, Liu Wanshan continued to smoke one by one, his face was full of tears and laughter.

Standing next to the boss, the Secretary in a suit also looks sad. He wants to scold the boss, but he doesn't know who to scold

"This star technology It's about shutting us down. "

Liu Wanshan sighed as he played the ash.

"It's really not a good day."

Although the stock price of Zhongshan new material has soared for some time, the number of orders has plummeted.

In particular, there are several small factories that have placed orders, and they even break the contract directly. The car batteries produced by them are not needed at all, so that he has a large number of goods on his hands now, and he has to worry about how to dispose of these things.

The only thing that makes him a little relieved is that they are not the only ones facing this dilemma. Now the whole battery industry is not very comfortable. Zhongshan new material also has lithium material business in the upper reaches of the industrial chain, and mobile phone battery business in another industrial chain.

By contrast, it's not too hard to breathe.

But it's hard to be sure.

Standing beside Liu Wanshan, the Secretary asked with a heavy face.

"Boss, let's What to do now. "

After a puff of smoke, Liu Wanshan thought for a moment and said.

"Turn off the battery production line for the time being. Some workers will transfer to the battery production line for mobile phones, and train them to work as soon as possible. There is also the business side of modified PDMS materials and hcs-2 materials. Hurry up the payment of downstream manufacturers as soon as possible, and let them get the money as soon as possible. When the lithium-air battery comes out, we will follow up immediately. In any case, we must ensure the cash flow and enough bullets in our hands, so as to win the battle! "

The Secretary nodded.

"OK, I'll do it later."

Looking at the piles of goods in the factory, Liu Wanshan felt a pang of flesh in his heart, but it was also impossible.

Turning around, he walked out of the factory and cut off his cigarette end. Liu Wanshan threw it into the garbage can beside him and looked back at the factory again.

That's worth tens of millions!

The more I think about it, the more unwilling it is. Liu Wanshan stomps heavily.

"No, I have to consult Professor Lu."

"Star technology has our shares, somehow. He can't help at all!"
