Black technology starts from the steel suit

Chapter 90 90 Cheap Energy Storage Solutions

In the afternoon of the same day, Wang Feng was staying in the laboratory, anxiously waiting for the experimental results with the original supercapacitor development team.If it's normal, or even before that, Wang Feng doesn't mind giving them a face and going out for a meal with those entrepreneurs.

However, after the development of cheap energy storage technology entered a critical period, breakthroughs have been made in the development of low-cost electrometric pseudocapacitor supercapacitors. Under such circumstances, Wang Feng is too lazy to fight hypocrisy with them.

They are a group of war slags who have the opportunity to embark on the road of internationalization and high-end development only by relying on national support and policy preference. The vehicle control system of new energy vehicles, as well as the motor management system and battery management system, are basically It was developed by Huaneng Battery and Huawei.

Not to mention the core of new energy vehicles - the battery pack, this part is completely provided by Huaneng Battery, without these things, it is impossible for them to squeeze into the high-end market.

It can even be said that without the electronic controls of Huaneng and Huawei, they would not be able to manufacture a new energy vehicle under the collective supply cut-off of 14 foreign electronic control companies.

To put it nicely, they are the East Asia United Motor Company.To put it bluntly, they are the East Asia United Automobile Assembly Plant, and they don't have their own core technology at all.Under such circumstances, what can they be arrogant about?
Of course, the current results may have made them flustered, but they will soon have a sense of crisis. Whether it is Wang Feng or the above, they may really give up such a big factory as FAW or SAIC. It's just because they consider that they may bully customers, and turn their backs on customers.

But even these car factories don't have any face in front of him, they all rely on him for food. If Wang Feng is unhappy, he will be kicked out directly. The car brand and production capacity will not be wasted, and they will be split directly. Reorganization or mergers and acquisitions are enough. They are all the assets of the state. In the final analysis, the state has the final say, but it is just a change of manager.

And there are two to three automakers competing with each other to form a virtuous circle, which is exactly what everyone wants to see.Thinking of this, Wang Feng felt much more secure, and he refocused on the experiment.

After about 20 minutes, Xu Jiayan finally came out with an excited face: "Professor Wang, we have succeeded!"

Xu Jiayan took the experimental report in his hand and introduced to Wang Feng: "We prepared manganese dioxide hydrate material by hydrothermal method, and designed an energy band structure that is conducive to interfacial electron transport through the compounding of different metal materials."

"A TiO2 intercalation layer was introduced at the MnO2/Ni(OH)2 interface, and the MnO2/TiO2/Ni(OH)2 core-shell structure nanowire array was prepared as the positive electrode material, which effectively reduced the electron interface transport barrier during charging and reduced the reduction The activation energy in the reaction increases the capacitance."

"At the same time, we further prepared MnO2/Fe2O3 composite nanomaterials as the negative electrode of supercapacitors by hydrothermal method, and assembled asymmetric supercapacitors. The voltage window of the device was extended to 1.6V, and when the current density was 1A g-1, the specific capacitance It is l46.8F·g-1, when the power density is 1350W·h·kg-1, the energy density is 52.22W·h·kg-1."

"Then we further optimized the electron transport properties of the cathode material interface, and used the hydrothermal method to grow MnO2/NiO core-shell structure nanowire arrays on the three-dimensional carbon cloth substrate as flexible self-supporting electrodes. Embedded with silver nanoparticles, when the current density is 2A cm-5, the capacitance of the MnO2/Au/NiO electrode material is 2F cm-4.1, which is several times higher than before."

"It turns out that our calculations are not problematic. The addition of nano-scale silver particles can form a potential well between MnO2 and NiO, trap a small amount of electrons, and improve the charge storage capacity."

"Yes, it seems that you have understood a lot of what I said!" Wang Feng also said very happily. Although he was very happy that his laboratory had produced another major achievement, what is even more gratifying is that, Both he himself and his fellow researchers were able to make a major academic breakthrough.

"Those theories have a great guiding effect on us. Professor Wang, when do you plan to publish it?" Xu Jiayan asked.

"Yes, Professor Wang, when are you going to publish your paper?" The researchers participating in the experiment asked impatiently. Although their research results today are very important, if they want to publish a paper, the protagonist of the paper Not him, but the methods used in this study.

And their research results are just a strong support under this big theoretical framework.

Compared with these visible benefits, researchers hope to achieve some results in theoretical research. A scientific and technological achievement may be forgotten after ten years, at most no more than 20 years.

However, as long as a theoretical achievement is not wrong, even if it has some defects, its vitality is far beyond that of scientific and technological achievements. Newton's three laws are still the theoretical basis governing modern human social activities until now.

And this is exactly what researchers are pursuing, the so-called achievement and fame, writing books and biographies.

"Yes, Professor Wang, we are still waiting for your paper to be published before we can show today's results!" Xu Jiayan said bluntly. He had a good relationship with Wang Feng, so he spoke more casually.

"I reckon that this kind of achievement can at least be published in the top journal, let alone a JACS!" Someone next to him echoed, and a major scientific research achievement such as the microstructure model of the electrochemical interface must be properly published in nature. .

Although they only did an empirical work, the project of cheap supercapacitors is also being done by many laboratories, which belongs to the category that has attracted wide attention. The last JACS was not too much.

"It will take a while." Wang Feng said after thinking for a while, "Although we have produced substantive evidence, this theory is still not perfect."

"You don't need to wait for me, you can publish the results first."

"How embarrassing is this, why don't you hang up a work?" Xu Jiayan said a little embarrassedly, although he was very moved.

"Forget it once. After all, this is done by your own hands. You can just assign me to the corresponding author." Wang Feng said with a smile. He has already won the first prize of the National Natural Science Award. It is just icing on the cake, but for these young researchers, it is indeed very important.

"Then how is it possible? Although we did the work, without your theoretical guidance, such a major breakthrough would definitely not be possible for us." Xu Jiayan declined.

"You have all worked hard during this period." Wang Feng said in a tone that could not be refused: "Since I told you, you can just accept it with peace of mind."

"If you have time, you'd better introduce me to its detailed data."
