The clay figure also has three attributes, and her hard work and hard work have been criticized by others, and Miss Zhou Yue's heart is naturally very unhappy, not to mention, her purpose of showing this thing to Liu Feng is more to get praise from this guy!

Well, this time, she's quite confident in her research!

Being Professor Liu's apprentice, although he can obtain unimaginable benefits in a series of aspects such as resources and prestige, but in addition, the pressure he faces is not understandable to ordinary people.

If you succeed, others will only say that you are because you have a good teacher, and if you fail, others will say how this apprentice is so unsuccessful!

The young lady is also an ambitious person, she doesn't want to be under Liu Feng's wing for the rest of her life, she also wants to prove herself!

Therefore, the reason why Zhou Yue wants to study superconducting batteries, on the one hand, is to realize the long-cherished wish of three generations of a family, on the other hand, she also wants to further prove her meaning through the research of superconducting batteries.

However......

The boss is still the boss, and the student is still the student after all.

They are all the same age, do they need to hit us like this?

twitched the corners of her mouth, and the young lady lifted her black-framed glasses, "crying": "Boss, you, what do you mean, isn't the superconducting battery we are studying not performing well......"

In fact, Liu Feng proposed two sets of plans for the development of superconducting batteries using superconducting materials.

Needless to say, the first set of schemes is developed to directly use superconducting coils to store electrical energy in the form of electromagnetic energy, and then output electrical energy to the load when needed.

After all, the superconducting coil runs in the superconducting state without DC current Joule heat loss, and the average current density it can conduct is several orders of magnitude higher than that of the general conventional wire coil, and the magnetic field strength is high, and the energy storage density is also very high, up to 10^11J/m3, and can be stored for a long time without loss, the advantages are quite obvious.

As for the other solution, the superconducting material is used as the battery cathode to improve the energy density and charge-discharge life of the traditional lithium-ion battery on the basis of the traditional lithium-ion battery.

As we all know, in general, the main part that restricts traditional lithium batteries is the positive and negative electrode materials of the battery, especially the positive electrode of the battery.

The theoretical gram capacity of graphite is 372mAh/g, which has a high upper limit, while the theoretical gram capacity of lithium iron phosphate is only 160mAh/g, and the ternary nickel-cobalt-manganese (NCM) is about 200mAh/g.

According to the barrel theory, the water level is determined by the shortest part of the barrel, so the lower limit of the energy density of lithium-ion batteries depends on the cathode material.

If the lower positive limit of the battery can be increased with superconducting materials, the energy density of the battery can be greatly improved.

The advantage of this scheme is that it is less difficult to develop, and the technology is more mature - after all, it is just to replace the cathode material of the battery with a superconducting material at room temperature!

The key is that the cost of this scheme is relatively low compared with the first set of schemes, and the superconducting materials used are very few, and the price is naturally relatively low, but the disadvantage is that it cannot fully exert the effect of superconducting materials, so that both energy density and charge and discharge performance will still be subject to the characteristics of lithium-ion batteries, which are completely inferior to superconducting electromagnetic energy storage devices and become epoch-making explosives.

To a certain extent, things gather people in groups, and the temperament between master and apprentice is very similar, whether it is Liu Feng or Miss Zhou Yue, in scientific research, both of them are obsessive-compulsive patients, of course, to do the best, and must do the best!

Therefore, there is no doubt that Zhou Yue chose the former.

The results were not surprising.

At present, the maximum energy density of power lithium batteries on the market will not exceed 200Wh/kg, even if it is the legendary lithium-sulfur and lithium-air batteries in the laboratory, it will not exceed 500Wh/kg, after all, the energy ceiling of lithium-ion batteries is not only positive and negative electrode materials, but also other limitations;

However, the energy density of this superconducting battery, which Miss Zhou Yue directly uses a superconducting coil to store electrical energy, has exceeded 10,000Wh/kg for the first time!

Not at all in an order of magnitude!

As for the number of chargeable and discharged, not to mention, as long as the superconducting coil is not damaged, the number of chargeable and discharged times is theoretically unlimited, and the service life of traditional lithium batteries is only about 1000 charge-discharge cycles......

Such an excellent superconducting battery, put in the mouth of Professor Liu, it turned out to be a mess?

It's no wonder that the young lady's mood can get better!

Liu Feng didn't pay attention to the young lady's thoughts, and didn't eat her "crying" set, and asked directly: "Let me ask you, what is the purpose of your research on this superconducting battery?"

Zhou Yue: "Of course it's a car." ”

Liu Feng was unceremonious: "Build a car, I think you want to build a time bomb! 10,000Wh/kg you still don't think it's enough, and you want to break through the energy density to more than 20,000Wh/kg, do you dislike KBFZ's car bomb is not powerful enough?"

The high energy density of the superconducting battery depends entirely on the stability of the entire superconducting battery, theoretically, as long as the stability is sufficient, the energy density of the superconducting battery can exceed 50000Wh/kg!

However, when the energy density exceeds 15000Wh/kg, the entire superconducting battery is no longer a battery, and it can be called a plasma bomb!

That's right, the legendary superconducting plasma bomb!

Once the internal situation of the battery is slightly unstable, or it is bumped by the outside, the entire battery system will explode instantly under the impact of strong energy, as for the power of the explosion, it depends on how big the battery pack is;

But at least, with the superconducting battery designed by Miss Zhou Yue, which can store tens of thousands of kilowatt-hours or even hundreds of thousands of kilowatt-hours of electricity, it is quite easy to blow up an inch of grass within a radius of more than ten meters around the car.

Liu Feng couldn't imagine whether people would take a car or a ferry boat to Huangquan at that time......

What's more, the battery is still a very comprehensive product, you want to improve the performance of a certain aspect, may sacrifice the performance of other aspects, this is the basis for the understanding of battery design and development, and the automotive power battery belongs to the vehicle, so the energy density is not the only measure of battery quality.

Even if you can guarantee the safety of the battery, you can make the car run to the end of life on a single charge, and in a few decades, it is an unrealistic idea!"

"At present, the electric vehicles on the market, the NEDC comprehensive range is generally about 200km, and even 300km is very few, even so, the cost is generally more than double that of traditional fuel vehicles of the same level!

When Liu Feng said this, Miss Zhou Yue on the other side had already lowered her head unconsciously, why don't you sell it to you first?

"I also know that your original intention of this design is also good, no need to charge, no need to worry about mileage limitations, completely from the perspective of consumers for their sake, but ...... Alas!"

It's still too naïve!

If you can run 500,000 kilometers of electric vehicles on a single charge, according to the current electric vehicles are generally in 1~2 tons of tonnage, 100 kilometers at least 10 kilowatt-hours of electricity to calculate, how can you get 50,000 kilowatt-hours of electricity, if you calculate according to the energy density of the battery pack at 50,000Wh/kg, the weight of the battery pack alone has reached 1 ton, that is, the weight of superconducting materials is almost 1 ton!

1 ton of superconducting materials, according to the current value estimate, how can it exceed 1 billion yuan, even after 10~20 years, after a breakthrough in large-scale industrial production technology regardless of cost, the cost will be reduced to one thousandth, and each ton will exceed 1 million yuan.

This is just the production price of battery materials, not to mention the cost of a series of protection measures for battery stability, as well as the manufacturing cost of other parts of the car.

looked at the young lady in the video speechlessly.

He's a baby apprentice, he does have a hand in scientific research, but when it comes to business acumen, he is not even as good as a primary school student, and he can't even make basic trade-offs!

"If you really plan to open your own company to build an electric car and carry it forward, I advise you to hand over the company to someone else to take care of, so as not to lose all your pants when you get it!"

Zhou Yue: "......"

I'll give you the pants, do you dare to ask for them?

Although he is very speechless about Liu Feng's analogy, I have to say that his boss is the person who has become the richest man in China and is about to surpass Bill Gates, and his business ideas are indeed somewhat reasonable......

Zhou Yue blushed embarrassedly: "Boss, I, am I stupid?"

"It's not hopelessly stupid," Seeing that the young lady lowered her head and blushed with shame, Liu Feng also secretly asked if he was too strict with her, so he relieved, "At least, in terms of scientific research talent, you are still compatible, well, good." ”

Zhou Yue: "......"

Is it good or good?

Can't you even give an excellent one?

Unwilling to stare at his paper: "So, boss, what do you think I should do?"

Liu Feng shook his head helplessly and sighed: "You, you! In terms of attitude towards scientific research, constantly climbing the peak of science and technology is the quality that a qualified scientist should have, so if you want to study superconducting batteries with higher energy density, this is still worth affirming." ”

"But as a good entrepreneur, in addition to constantly investing in new technologies, you also need the necessary business skills! ”

"Boss, but I really don't have time right now...... I didn't want to be an entrepreneur......" Zhou Yue subconsciously frowned, and said weakly, "Or, you tell me how many density superconducting batteries should be developed, and when we develop superconducting batteries, you will arrange a few professional managers for me to help take care of something?"

Speaking of this, the young lady suddenly thought of a perfect solution, and her eyes lit up and said: "Do you have a specialization in the art industry, isn't this arrangement perfect? Of course, if you can invest some start-up capital or something for us, it will be even more perfect." ”

Liu Feng: "......"

How can I feel deceived and beaten by local tyrants?

……

After some intense "tweaking" by the elders to the juniors, the video ends.

Although Zhou Yue was criticized by Liu Feng for having no business acumen, he turned around and flickered a venture capital from the teacher...... Finally hung up the video contentedly.

Liu Feng in front of the computer sighed with Zhuo Tingting with a resentful face: "Other people's apprentices take the initiative to share the teacher's worries, why do my Liu Feng's apprentices all count me as a teacher?"

Staring at his lover with admiration, the young lady brushed the placket of his body and said with a smile: "Who told our Professor Liu to be tireless, virtuous, and helpful?

"Alas, that's fine!" Liu Feng didn't just really care about this, he shook his head, and he didn't know what he was sighing, "Alas, we are born to work hard!"

After speaking, he took out his mobile phone and gave Zhang Qin a call.

Well, his apprentice is going to start a business again, and as a mentor, he can help a little bit!

"What, you guys want to build cars again?"

Hearing Liu Feng's idea of wanting to build a new energy electric vehicle again, Zhang Qin was a little speechless, why is this guy so unprofessional?

"That's right, the main thing is to support the ideas of the apprentices, and by the way, I also invested in some water. Liu Feng said a little embarrassed, it seems that as soon as something happens, he is bothering this Zhang Dabu chief?

Blame the embarrassment.

However, he said that he was embarrassed, but in action, this guy was unsuccessful, the law of true fragrance, "Trouble brother, can you help me see if it can be done, are there any restrictions on the country's policy in this regard......"

"Forget it, you can do it if you like it,"

Zhang Qin on the other side didn't care too much, didn't he just build a car, even if this guy wanted to build a spaceship or a time machine or something like that on a whim, he had to be 'happy to accompany',

"There is no problem with the policy at all, the Ministry of Automobile Industry and Information Technology, when you are ready, I will go directly to say hello to them, it is not a big problem!"

Get!

……

Time passed day by day, and after more than 20 days, Fenghua Research Institute High Energy Materials R&D Center.

"Senior sister, all of the 98 experiments are in accordance with your requirements, and we have made exciting progress. The stability test, energy density test, overload, overcharge and discharge test of the superconducting battery have all met the perfect requirements, and it is exactly the same as the theoretical prediction you gave!"

As soon as he arrived in the laboratory, Jiang Yide, who learned that the main owner was coming, excitedly found her and reported the progress of the research.

Well, the senior sister and the junior brother, it is only natural that the three apprentices newly accepted by Liu Feng are basically led by Zhou Yue, the senior sister, which is also a fine tradition that Liu Feng learned from Boss Duan!

Of course, in return for leading the younger siblings, it seems natural to ask them to do some experiments for themselves or something.

"Well, this is a critical test for superconducting batteries to be put into real-world applications. ”

Zhou Yue listened, but there was not much emotional fluctuation, compared to the previous development of superconducting batteries from scratch, this kind of experimental experiments, can not arouse her interest at all, if not these experiments related to the safety and reliability of superconducting batteries "on the car", had to do it, she didn't even want to do such a low-level thing!

I went to the laboratory to check the experimental data report, and after confirming that it was correct, she began to arrange the next development link, and by the way, she called Liu Feng to report the good news here.

On the other hand, after learning that the superconducting power battery was completely successful, Liu Feng once again called Zhang Qin and talked about building a car.

"Why, you guys made it so quickly?"

"Yes, that's right. ”

Liu Feng glanced at the experimental report sent to him by Zhou Yue and looked away, explaining: "The biggest technical difficulty - the power battery can basically be declared broken, the purpose of contacting you this time is to know what needs to be prepared by the Ministry of Automobile Industry and Information Technology, of course, by the way, ask the government or the military can purchase points by the way?"

"You guy! still have this idea?" Zhang Qin couldn't cry or laugh, "I can help with the Ministry of Industry and Information Technology, but when it comes to procurement, you should lobby other departments yourself, according to the regular channels, don't want me to open the back door for you." ”

"Brother, don't you think we're also here to develop national industry? We have invested a lot of money for the country, so you have to support it!" In the blink of an eye, Liu Feng has become a shameless car salesman.

Zhang Qin shook his head helplessly: "I'm afraid of you, our Ministry of Science and Technology has a lot of procurement plans recently, I can help you ask, as long as the price is right...... By the way, how much do you quote for that car?"

"Well, then thank you brother for your support," Liu Feng said with a smile, "As for the unit price, it's not expensive, 15 million a car, with the relationship between the two of us, let's make a 20% discount, 12 million per car!"

Zhang Qin: "......"

1200, 10,000?

It can't be two more zeros, right?

You guys don't think I'm dying!

"What's the matter, brother?" Liu Feng seemed to understand something from his silence, and said with a smile: "Don't think about it with conventional thinking, our Liu Feng's apprentice, well, the car we Liu Feng built is specifically to break the convention." ”

"By the way, I forgot to tell you, our car is the only room temperature superconducting electric vehicle on the earth!

"These superconducting batteries alone are composed of a complex set of black technologies, activating pegboards, safety switches, emission matrices, lens groups, catheters, etc., and their internal high-power energy is delivered through an energy loop, and a series of focusing lenses and energy excitations that are charged with positive charges release charges, and then these charges carry enough energy and are applied to the system that can maintain the entire all-electric drive system...... Which one is not a waste of the power of the two tigers......"

"Stop, stop, stop!" As soon as he talked about technology, Zhang Qin knew that Liu Feng on the other side was going to make a tirade, and immediately ended the silence, and directly raised a middle finger to the sky, and said: "I don't understand what you're saying, I have reason to suspect that you are bragging, well, the procurement matter is over here......"

An electric car with a cost price of 12 million, can he buy one after selling Zhang Qin?

"Don't, brother!" Liu Feng on the other side continued to say, "12 million is not good, do you think 1.2 million is not good? 1.2 million is not good, what about 120,000? It's just that 120,000 cars, how can the delivery date be 10 years later...... Well, otherwise, 12 million will be able to deliver it to you in a month, buy it early and enjoy it early, and it is all handmade, and it has a face!"

Zhang Qin: "......"
