The clay man also has three-point attributes. She has been criticized for her hard work and hard research. Miss Zhou Yue is naturally very unhappy in her heart. What's more, the purpose of her giving this thing to Liu Feng is to get praise from this guy!

Well, this time, she is quite confident in her research!

Although being Professor Liu's apprentice can gain unimaginable benefits from resources, reputation and other aspects, in addition, the pressure faced is not something that ordinary people can understand.

If you succeed, others will only say that you are because of a good teacher. If you fail, others will say that this apprentice is so incompetent!

The young lady is also an ambitious person. She doesn’t want to be under Liu Feng’s wings for the rest of her life. She also wants to prove herself!

Therefore, the reason why Zhou Yue wanted to study battery guide was, on the one hand, not only to realize the long-cherished wish of three generations of family members, but also to further prove her intention through the research of battery guide. Otherwise, she would have taken on the task directly from Liu Feng, so why bother to find another thankless research direction?

However……

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

They are all peers, can we deal with this?

After twitching the corner of his mouth, the young lady held up the big black-framed glasses and said, "I was so excited": "Boss, what do you mean? Is the battery guide we are studying poor performance..."

In fact, Liu Feng proposed two plans for her to develop guide batteries using guide materials.

Needless to say, the first set of solutions is developed. It is a conductive electromagnetic energy storage device that directly uses conductive coils to store electrical energy in the form of electromagnetic energy, and then outputs the electrical energy to the load when needed.

The conductive battery developed on this principle can fully utilize the advantages of the conductive material. After all, the conductive coil operates in the conductive state without DC current Joule heat loss. At the same time, the average current density it can conduct is as high as that of a general conventional conductive coil. The magnetic field strength is high and the energy storage density is also very high. It can reach a maximum of 1o^11j/m3, and it can store energy without loss for a long time, which is quite obvious.

As for another solution, it is to use the conductive material as the positive electrode of the battery to improve the energy density and charging and discharge life of traditional lithium batteries on the basis of traditional lithium-ion batteries.

As we all know, generally speaking, the main part that limits traditional lithium batteries are the positive electrode and negative electrode materials of the battery, especially the positive electrode of the battery.

The negative electrode materials of existing lithium-ion batteries are mostly graphite. The theoretical capacity of graphite is 372mah/g, and the upper limit is very high. The theoretical capacity of the positive electrode material lithium iron phosphate is only 16omah/g, and the ternary material nickel cobalt manganese (ncm) is about 2oomah/g;

According to the barrel theory, the water level is determined by the shortest point of the barrel. Therefore, the lower limit of the energy density of the lithium-ion battery depends on the positive electrode material.

If the battery's positive electrode lower limit can be increased with conductive materials, the battery's energy density can be greatly improved.

The advantage of this solution is that it is relatively difficult to develop and the technology is relatively mature - after all, it is just a replacement of the positive electrode material of the battery with a room temperature guide material!

The key is that compared with the first set of solutions, the cost of this solution is very few, so the price is naturally relatively low. However, the disadvantage is that it cannot fully utilize the efficacy of the guide material, so that it will be subject to the characteristics of lithium-ion batteries, which is completely incomparable to the electromagnetic energy storage device and become an epoch-making explosive product.

To a certain extent, birds of feathers gather together, and the temperaments between masters and apprentices are very similar. Whether it is Liu Feng or Miss Zhou Yue, both of them are obsessive-compulsive disorder in scientific research. Of course, they should do the best, and they must do the best!

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

The result is naturally not unexpected.

The maximum energy density of the power lithium batteries on the market will not exceed 2ooh/kg, and even the legendary lithium sulfur and lithium air batteries in the laboratory will not exceed 5ooh/kg. After all, the energy limit of lithium-ion batteries is not only positive and negative electrode materials, but also other restrictions;

However, the energy density of this kind of battery that uses a coil to store electrical energy has exceeded 1ooooh/kg for the first time!

Not on the same order of magnitude at all!

As for the number of charge and discharge times, let alone the number of charge and discharge times. As long as the coil is not damaged, the theoretical number of charge and discharge times is unlimited. The service life of traditional lithium batteries is only around 1 ooo charge and discharge cycle...

Such an excellent guide battery was so messy when it was put in Professor Liu's mouth?

It would be strange that the young lady can get better!

Liu Feng ignored the young lady's thoughts, and did not accept her "sighingly crying" trick, and asked directly: "I ask you, what is the purpose of studying this kind of battery guide?"

Zhou Yue: "Of course it's a car."

Liu Feng was not polite: "Making a car? I think you want to build a time bomb! 1ooooh/kg is not enough. If you want to break the energy density to above 2ooooh/kg, do you dislike the kbfz car bomb's power not enough?"

The high energy density of the guide battery depends entirely on the stability of the entire guide battery. Theoretically, as long as the stability is sufficient, the energy density of the guide battery can exceed 5ooooh/kg!

However, when the energy density exceeds 15oooh/kg, the entire guide battery is no longer a battery and can be called a plasma bomb!

That's right, the legendary conductive plasma bomb!

Once the internal situation of the battery becomes slightly unstable, or it is subject to external bumps or bumps, the entire battery system will explode instantly under the impact of powerful energy. As for the power of the explosion, it depends on how big the battery pack is;

But at least, it is quite easy to use the conductive battery designed by Miss Zhou Yue that can store tens of thousands of kWh or even hundreds of thousands of kWh of electricity to make it impossible to make it within a radius of more than ten meters around the car.

Liu Feng could not imagine whether people would be riding in a car or a ferry boat leading to the Huangquan...

What's more, batteries are still a very comprehensive product. If you want to improve performance in one aspect, you may sacrifice performance in other aspects. This is the basis for understanding battery design research. Automotive power batteries are exclusively for on-board vehicles, so energy density is actually not the only measure of battery quality.

"The safety is unguarded! Even if the battery is safe, it is unrealistic to let the car charge once and run to scrapped designs for decades!"

"At present, the comprehensive range of electric vehicles on the market is generally around 2ookm, and there are very few 3ookm. Even so, the cost is generally more than twice that of traditional fuel vehicles of the same level! But you are just trying to launch such an electric vehicle that can run 50,000 kilometers. Do you want to sell it to the world's wealth only?"

When Liu Feng said this, Miss Zhou Yue opposite him had already lowered her head unconsciously. Why not sell it to you first?

"I also know that the original intention of your design is also good. You don't need to charge or worry about mileage restrictions. You are completely thinking about them from the perspective of consumers, but...ah!"

Still too naive!

Electric vehicles that can run 50,000 kilometers by charging once, according to the current tonnage of 1 to 2 tons of electric vehicles, and if they are calculated at least 10,000 kilometers of electricity, they will have to increase the power of 50,000 kilometers of electricity. If calculated based on the energy density of the battery pack at 5ooooh/kg, the weight of the battery pack alone will reach 1 ton, which means that the weight of the guide material is about 1 ton!

According to the current value estimate of 1 ton of guiding materials, it will have to exceed 100 million yuan. Even after 10 to 20 years, after a breakthrough in large-scale industrial production technology regardless of cost, the cost will be reduced to one thousandth of a thousand, and each ton will exceed 100,000 yuan.

This is just the production price of battery materials, not to mention the cost of some protection measures for battery stability, as well as the manufacturing cost of other automobile parts. In addition to being used as a toy for rich people, can ordinary people afford it?

Watching the young lady in the video speechlessly.

He is a baby apprentice, and he is indeed very good at doing scientific research, but when it comes to business acumen, he is even worse than elementary school students, and he can't even make basic choices!

"If you really plan to open a company and build an electric car by yourself and make it prosperous, I advise you to leave the company to others to take care of it, so as not to lose all your shorts!"

Zhou Yue: “…”

I'll compensate you for the shorts, do you dare to ask for them?

Although he is speechless about Liu Feng's metaphor, it has to be said that his boss has become a wealthy man in China and is even about to surpass Bill Gates. His business ideas are indeed reasonable...

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

"I'm not hopelessly stupid yet," Liu Feng also thought to himself if he had demanded too severely on her, so he comforted, "At least, in terms of scientific research talent, you're still in line, well, good."

Zhou Yue: “…”

Is it qualified or good?

Can't you even give me an excellent one?

He stared at his paper unwillingly: "So, boss, what do you think I should do?"

Liu Feng shook his head helplessly and sighed: "You, you! Judging from his attitude towards scientific research, constantly climbing the peak of science and technology is a quality that a qualified scientist should have. Therefore, if you want to study a higher energy density guide battery, this is worthy of recognition."

"But as an excellent entrepreneur, in addition to constantly investing in new technologies, necessary business skills are also necessary! This way, if you have time, take time to recharge at the next door to Kyoto University or Shuimu's School of Business Administration next door."

"Boss, but I really don't have time now... I never thought about becoming an entrepreneur..." Zhou Yue subconsciously frowned and said weakly, "Or what density of guide batteries should be turned on. When we turn on the guide batteries, you can arrange a few professional managers to help me with the help of some?"

Speaking of this, the young lady suddenly thought of a perfect solution, and her eyes shining: "Do you have a specialty in your career? Is this arrangement perfect? ​​Of course, if you can invest in some startup capital for us, it will be even more perfect."

Liu Feng: “…”

How come I feel like I was deceived and beaten to a rich man?

...

After a fierce "teaching" between elders and younger generations, the video ended.

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

However, Liu Feng, who was in front of the computer, sighed to Zhuo Tingting with a resentful look on his face: "Their apprentices take the initiative to share the worries of the teacher. Why are my Liu Feng's apprentices all plotting against me as a teacher?"

Staring at his beloved, the young lady stroked his clothes and said with a smile: "Who told our Professor Liu to be tireless in teaching, have good teacher ethics, and are willing to help others? In addition, he is a big rich man, who do you want to 'calculate' if you don't 'calculate'?"

"Oh, okay!" Liu Feng didn't just really care about this, shook his head, and didn't know what he was sighing, "Oh, we are born to be a hard-working person!"

After saying that, he took out his cell phone and called Zhang Qin.

Well, his apprentice is going to start a business again. As a mentor, I can help you if you can!

"What, you guy wants to build a car again?"

When Zhang Qin heard that Liu Feng wanted to build a new energy electric vehicle again, he was speechless. Why is this guy so incompetent?

"That's right, I mainly support my disciples' ideas, and I also invested in some trials." Liu Feng said embarrassedly, as if he was troubled by the way, he would bother this Zhang Dabu.

I'm sorry.

However, he said sorry, but this guy was very happy in his actions. The law of "I'm sorry, brother, please help me see if it can be successful. Is there any restrictions on the country's policies in this regard..."

"Forget it, you can do it,"

Zhang Qin on the opposite side didn't care too much about it. Wasn't he just building a car? Even if this guy wanted to build a spaceship or time machine, he had to be "happy with him."

"The policy is completely free. The Ministry of Automobile Industry and Information Technology, when will you be ready, I will go directly to say hello to them. It's not a big problem!"

Get it done!

...

Time passes day by day, and twenty days later, the Fenghua Research Institute High Energy Materials Research Center.

"Sister Sister, all No. 98 experiments have been in accordance with your requirements, and we have made exciting progress. The stability test, energy density test, overload, and overcharge and discharge test of the guide battery have reached the perfect requirements, which is exactly the same as the theoretical predictions you gave!"

As soon as he arrived in the laboratory, Jiang Yide, who learned that the main owner had arrived, was excited to find her and report on the research progress.

Well, it is natural for the senior sister to take care of her junior sister. The three apprentices that Liu Feng has newly accepted are basically led by Zhou Yue, the senior sister. This is also a fine tradition that Liu Feng learned from Boss Duan!

Of course, in return for leading the junior brothers and sisters, it seems natural to ask them to do some experiments for themselves.
To be continued...
