Used on tanks......

Hearing this strange question, and then looking at those solemn and eager eyes, Lu Zhou finally understood what Director Lu was here for.

In fact, the research on electrically driven tanks is not a very new thing.

As early as the thirties of the last century, "Dr. Porsche" studied this topic.

The VK4501P tank, which is equipped with a Porsche Type 101/1 air-cooled engine, is stored in a battery and then driven by two 275kW electric motors, which undoubtedly meets the basic characteristics of an electrically driven tank.

However, due to the limitations of the times, this technology of electrically driven tanks was not able to play a great advantage on the battlefield, and only the design of the "differential steering system" was retained.

In the following century, with the continuous progress of science and technology, the concept of electric tank was repeatedly discussed.

Lu Zhou could guess that Director Lu didn't just ask this question to see if this thing could be used in a tank.

What he really wants to ask is probably whether the development dividends brought by controlled nuclear fusion can spill over from the economic field to the military industry......

"You have to ask an expert in the field of military industry," after thinking for a moment, Lu Zhou answered this question seriously, "But in my opinion, whether it is a lithium-sulfur battery or a lithium-air battery, the future in the military field is limited." ”

When Director Lu heard this, he suddenly became a little anxious, and hurriedly asked.

"Why?"

"Security." Lu Zhou sighed and said, "As long as it is a chemical battery, it is basically based on redox reaction to realize the conversion of electrical energy and chemical energy. Since it is a redox reaction, there is a great deal of instability. Especially lithium, which can spontaneously combust when put into the air, if it is hit by a shell or something, it is not as simple as an oil leak, but I am afraid that there is no chance to do emergency measures, and it will be 100% killed. ”

Someone must have told him about it.

However, looking at Director Lu's appearance, someone may have mentioned it, but he didn't take it too seriously.

“…… That's right. ”

After hearing Lu Zhou's answer, a trace of regret appeared on Director Lu's face.

Obviously, before coming here again, there should have been a technical demonstration meeting on this proposition in Beijing. And judging by the expression on his face, he should support the use of lithium-air batteries in the military industry.

After staring at the teacup on the table for a long time, the old gentleman still raised his head a little unwillingly and asked unwillingly.

"Isn't there room for improvement? For example, to make a battery that can balance stability and high energy density? ”

"I'm afraid the kind of thing you're talking about isn't something that a chemical battery can do......"

Lu Zhou didn't know what to say about him, shook his head, paused for a moment, and continued.

"Actually...... I don't know much about military affairs either. However, if it is only based on my personal understanding, although it is unreliable to use lithium-air batteries for front-line combat units such as tanks, it should still be feasible to use lithium-air batteries for non-front-line combat units such as transport vehicles, military trucks, and even transport helicopters to alleviate the dependence of the logistics system on oil. ”

The electric engine has great advantages in terms of noise, concealment, and handling.

Especially in a defensive war, under the premise that basic power facilities can be guaranteed, the advantages of electrification of this logistics system are still obvious.

As for offensive wars......

China is a peace-loving country, so we will not discuss this for the time being.

Seeing the thoughtful expression on Director Lu's face, Lu Zhou smiled and continued.

"Actually, I'm a pacifist myself, and I don't have much research on weapons, but if national defense construction needs my advice, I can only say that instead of looking for a way out of chemical batteries, it is better to think of ways from other places."

Director Lu immediately asked, "Elsewhere?" ”

Lu Zhou nodded and continued: "For example, controlled fusion technology, now I have come up with a miniaturized controllable fusion battery, although there are still many limitations such as high cost, but there is always a process of scientific progress. As long as you continue to invest in this field, maybe in a decade or twenty, small fusion batteries will mature to the effect you imagined. ”

Controlled fusion miniaturization technology has been used in a series of spacecraft such as Xiangrui, Xiaguang, and Queqiao, and the current new generation of deep-sea nuclear submarines is said to be equipped with the same type of battery.

Lu Zhou remembers that he saw an order from the Chinese Navy's equipment procurement department on the account sheet of the Space Shuttle Assembly Center, and the amount of purchase seemed to be not small.

While there is still a long way to go to move this technology from the sky and sea to land, and to reduce both the cost and the minimum size to an acceptable level, who can say what the future holds?

As long as you continue along this path, there will come a time when you can still see the hope of realization.

……

The further miniaturization of fusion batteries is a matter of the future, and no matter how Lu Zhou draws the pie of fusion batteries to the second-in-command of the Energy Bureau, the entire new energy vehicle industry is going crazy at this time.

The downstream supply chain is okay, several major domestic new energy vehicle manufacturers convened engineers to study Lu Zhou's paper overnight, and deduced from the wording of a few words, although this kind of lithium-air battery should have little impact on them, only the design of the air intake grille in front of the car should be on the line.

Whether it is optimistic or really has little impact, in short, the major new energy vehicle manufacturers are reluctantly relieved.

But a sigh of relief is a sigh of relief, but that doesn't mean they're just letting it go.

In view of the potential impact of uncertainties in the new energy industry, companies such as BYD have postponed the new cars that were originally scheduled to be launched in the near future, preparing to wait until the dust settles on lithium-air battery technology before launching new models, and have begun to design new energy vehicles with air intake grilles that meet the expectations of "lithium-air batteries".

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

However, these automakers are relieved, but for the midstream enterprises of the entire supply chain, especially those automotive battery manufacturers, it is uncomfortable.

The boss, who has been waiting for two years and finally made up his mind to complete the upgrade of the production line, can be said to have gray hair overnight.

The new energy industry is indeed becoming more and more prosperous, but the products they produce have been eliminated......

In the warehouse of Zhongshan New Materials.

Looking at the mountains of lithium-sulfur battery inventory from a distance, Liu Wanshan continued to smoke cigarette by cigarette, and his face was full of tears and laughter.

Standing next to the boss, the secretary in a suit also had a sad face, wanting to scold for the boss, but he didn't know who to scold......

"This starry sky technology...... He's trying to shut us off. ”

After flicking the cigarette ash, Liu Wanshan sighed.

"It's really a hard time."

Although the share price of Zhongshan New Materials soared for some reason some time ago, the number of orders has plummeted.

In particular, there are a few small factories that have placed orders, but they have directly defaulted on the contract, and the car batteries produced are simply gone, so that he now has a large number of goods in his hands, 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 who are facing such a dilemma, and the entire battery industry is not very comfortable now. Zhongshan New Materials also has a lithium material business further upstream in the industrial chain, as well as a mobile phone battery business in another industrial chain.

In contrast, it is not breathless.

However, it is not comfortable, that's for sure.

Standing next to Liu Wanshan, the secretary asked with a heavy face.

"Boss, let's ...... Now what. ”

Taking a puff of smoke, Liu Wanshan thought for a moment and spoke.

"The car battery production line will be temporarily shut down, and some workers will transfer to the mobile phone battery production line and train them to work as soon as possible. There is also the business side of modified PDMS materials and HCS-2 materials, urge the downstream manufacturers to pay for the goods as soon as possible, let them call the money as soon as possible, and wait for the lithium empty battery to come out, we will follow up immediately, no matter what, we must ensure cash flow, and the bullets in our hands are sufficient, so that we can hope to win the battle! ”

The secretary nodded hurriedly.

"Okay, I'll do it in a moment."

Looking at the mountains of goods in the factory, Liu Wanshan felt a pain in his heart, but this was also something that could not be helped.

Turned around and walked out of the factory, pinched off the cigarette butt in his hand, Liu Wanshan casually threw it into the trash can next to him, and reluctantly glanced back at the factory again.

That's tens of millions worth of goods!

The more he thought about it, the more unwilling he became, and Liu Wanshan stomped his foot heavily.

"No, I have to talk to Professor Lu about it."

"Star Technology also has our shares over there, and he can't help at all!"
