After speaking, he nodded towards the staff next to him, and the picture on the big screen began to change.
In an open square, there are cranes, some strange instruments, and dozens of strips that are one meter long, half a meter wide, and fifteen centimeters high.
Hello, Professor Chen, all the preparations have been completed and you can start anytime!
Start!
Dear audience friends, this is the test site of lithium-sulfur batteries. I am Zhang Yueqi, the person in charge of the test site. Next to me is my partner, Professor Shen Yuanxing. Those behind us are members of our lithium-sulfur battery project.
In order to ensure the authenticity of this test, we invited expert teams from three new energy testing companies, namely Radio and Television Metrology, Zhongzhou Measurement and Control, and Beitest New Energy.
At the same time, four institutions including Kyoto City Notary Office, Pengcheng Notary Office, Modu Notary Office, and the State Bureau of Justice were invited to conduct notarization at the same time to ensure the authenticity of the results.
Every time Zhang Yueqi reported a name, the camera switched once. The huge lineup stunned all the netizens watching the live broadcast.
Chapter 278 Battery safety test with hot eyes
Fuck, Guangji is a state-owned listed company. I remember that it seems to be specially designed to undertake the calibration experiment tasks of military industry and national F. The testing is extremely strict. The future technology is so awesome that it even hurts itself.
This is not to deceive oneself, but to be confident in the lithium-sulfur battery developed by oneself, and also to give confidence to consumers.
The two companies Zhongzhou Measurement and Control and Beitest New Energy are not bad. Their main business is battery testing and safety. As long as these two companies pass the test, there is basically no problem.
I don't know how many ways to test, but the five tests that are often encountered are fire, water immersion, drop, extrusion, and acupuncture.
Netizens are still talking about it, looking forward to it, but also extremely nervous, for fear that something goes wrong in one of the tests, which will affect the time to market.
First test, fire!Divided into four steps, it takes about 2 hours and 3 minutes to start!
Following Zhang Yueqi's order, an oil drum with a diameter of about 50 centimeters and a height of 15 centimeters was pushed up.
With a bang, the flame of the test barrel was transpired, rushed out of a height of more than two meters, and then fell back. After about 60 seconds of warm-up, in the camera, you can see the air fluctuating like water ripples, which means that the temperature is too high The phenomenon of hot air distortion.
A shelf holding lithium-sulfur batteries was pushed up, and the lithium-sulfur batteries were engulfed in flames half a meter above the flames.
After being burned for 3 minutes, it was pushed down.
This burning time has exceeded 1 times of the national standard fire test for 3 minute.
In the shot, the burnt lithium-sulfur battery is intact except for its blackened surface.
This kind of test naturally aroused the amazement of countless netizens.
It's so awesome, I can feel the burning heat through the screen.
This test is too fierce. When encountering this kind of problem in reality, the car burns out. Does it matter if the battery explodes or not?What's the matter, take it back and continue to use it if it doesn't explode?
Not too bad, a good start, and I am more confident in the safety of lithium-sulfur batteries.
That is, you don't even look at who made it.
Zhang Yueqi stepped forward to explain in time: According to the test requirements, it needs to be left for 2 hours after burning to see if it will explode or catch fire!
Due to time constraints, we will put it aside first, and give the results after all the tests are over. Netizens don’t have to worry about dropping the battery, this battery will not leave our sight.
Netizens let out good-natured laughter.
Next, the second item, the seawater immersion test, is mainly to immerse the lithium-sulfur battery in 3.5% Nacl solution, 3.5% is the national standard requirement, and the immersion time is also two hours.
I saw the impartial officer took a tester and tested it in the sink. The instrument showed that the salinity of the water was 3.5%.
The concentration meets the requirements of the national standard and can be tested!
The staff put all one lithium-sulfur battery into the tank and completely submerged it.
Well, the immersion test of the second item is also to see the results after two hours, which happens to be the same as the fire test.
The third high-altitude drop test will be carried out next. The national standard requires a drop from a height of 1m. We have prepared experiments at three heights of 3m, 6m, and 9m.
The specific test process is that it needs to be dropped three times within 1 minute, and be inspected after 6 to 24 hours. It must not catch fire or explode, and pass the insulation withstand voltage and insulation resistance tests.
After Zhang Yueqi explained, a crane appeared, hanging a lithium-sulfur battery, and began testing.
The surface of the 3m drop is intact, the surface of the 6m drop is slightly deformed, and the surface of the 9m drop battery has obvious bends, but nothing serious.
The most horrifying thing was that there were several shots where the camera was placed under the test, and the lithium battery was clearly seen falling. Netizens watching the live broadcast were so frightened that they almost threw their phones out.
Audience friends, after the test, you need to wait 6-24 hours for the results. The live broadcast will wait until all the results come out before closing. The notary and the testing company will also be on site, so don’t worry.
Do I have to wait 24 hours?It seems that the work of the Justice Department is not easy!
Shit, sit there for 24 hours, give me money and I can do it!
Isn't the height of 9m too fierce? If you fall from 9m, you will die.
It's hard to say, unless the front of the car hits the ground directly, but it must be useless. This kind of test should prevent secondary accidents!
It's really impactful, and my heart goes up and down when I watch it.
Upstairs, are you brain-dead, if you don't go up and down, can you still go left and right?One after the other?
Zhang Yueqi didn't have time to talk to them and started the next test.
Extrusion test, under the pressure of 200KN, hold for 10 minutes, observe for 1 hour;
Within two hours, it went through 9 tests including internal short circuit test, continuous charging test, overcharge, penetration test, high voltage test, and electronic furnace test.
The number of people watching the live broadcast once exceeded 2.8 million, surpassing the record of Chen Nuo's live broadcast. It is estimated that this record will be maintained for a long time.
At lunch time, I wanted to suspend the test, but the netizens quit.
It is said that they cannot dampen their enthusiasm and enthusiasm.
Chen Nuo looked at it secretly complaining, is this enthusiasm and enthusiasm?What the hell, I just want to watch the excitement, I don't even bother to expose you.
The test continued, and two hours later, the scheduled 17 tests ended.
The weird test method opened the eyes of netizens, and the test screen is simply eye-catching.
Especially the last gunshot test, the most impactful.
Originally, there was no gunshot test in the national standard, which was also required by the above. The reason given was that what would happen if the car was shot after it was produced abroad?Chen Nuo was quite convinced by this reason.
Forget about the pistol, what the hell even got a sniper rifle, the bullet hit the lithium-sulfur battery and easily penetrated the lithium-sulfur battery.
The powerful impact sent the lithium-sulfur battery flying three to four meters, and landed heavily on the ground.
What the hell, does Professor Chen have any misunderstandings about domestic security?Can this thing appear?
I think, Professor Chen seems to think highly of me, how can I encounter snipers?
Hey, it is probably prepared for foreign countries. If this car is exported to foreign countries, this kind of scene will often happen, right?
I am strongly dissatisfied with this test, I request to see the positive video, photographer, it's time to show your bravery!
A reward of 1000 yuan is offered, I just want to see the frontal video, I want to see the flame of the bullet popping out of the chamber
The test lasted a total of 5 hours. Except for the immersion test, there was no result. The other test results were tested by three testing companies and four impartial offices, and all passed the test.
At this moment, netizens were excited and cheered.
The lithium-sulfur battery that has passed the safety test is already at the top level in the world.
It is impossible to get stuck on the battery in foreign countries.
Chapter 279 Impossible, absolutely impossible
Impossible, absolutely impossible!
A roar resounded throughout the conference hall, but the voice was a little stiff.
Everyone turned their attention to the source of the voice, only to see a foreign media reporter standing up with an excited expression.
The staff in charge of security immediately exploded and surrounded them in an instant. Some of them directly blocked Chen Nuo, forming a human wall.
The attention given to Chen Nuo by the higher authorities has already surpassed the treatment of other scientific research workers in China.
Wait a minute, let him talk!
Chen Nuo stopped the security in time, and it was strange that he could still come in with a weapon after going through five security checks.
He also wanted to know what the foreign media wanted to do?
Impossible, you are fake!
fake?what fake?
Chen Nuo asked back: Are you saying that the lithium-sulfur battery is fake, or that our safety test is fake?
It's all fake, you are a complete liar!
Chen Nuo's face suddenly turned cold: Comrade foreign media, please organize your language carefully when you say this, this is Xia Guo, and I can sue you just based on your words!
The face of the foreign media changed drastically, and they still said angrily: LG has been established for nearly a hundred years, but they have not made it. How could you do it?
Yes, our Panasonic is the strongest. Your batteries started so late, and the conventional batteries are not well done. How is it possible.
The Xia country compatriots present all glared at him. If they hadn't scruples about diplomacy, they would have rushed to be this reporter.
What kind of gangster logic are you guys talking about?If you start later than you, you must be worse than you?We can succeed in nuclear bombs and hydrogen bombs in that environment, why can't we succeed in the current environment of comprehensive development?
Are there few of us who surpass you?Shall I count them one by one?
Besides, lithium-sulfur batteries are ours, so what does it matter to you whether we make fakes or not?What are you so excited about?
Chen Nuo's series of rhetorical questions left the two foreign media speechless.
There are so many laboratories researching lithium-sulfur batteries all over the world. You are trying to use this despicable excuse to stop our research and development and make all our efforts go to waste.
Hearing this reason, Chen Nuo and other media and scientific researchers at the scene looked at this foreign media as if they were an idiot. Where did this guy come from?
Are brain circuits all this big?
It has nothing to do with us whether your lab gives up or not. If you want to continue research, just do it.
Besides, the papers have been published. Even if the experiments in these two days have not been fully restored, at least some of the steps should be done.
Especially the problem of lithium dendrites, if this is solved, wouldn't the safety of lithium-sulfur batteries be almost the same?
Even if your lithium-sulfur battery is real, the safety test is fake!
The foreign media seemed to realize that they had made a mistake, and they were still irrational.
What does it have to do with you?
It doesn't matter, the consumers of lithium-sulfur batteries are us, we can't take life as a joke!
The crowd was speechless again.
You are also worthy of life safety?There are so many guns that you can be killed on the street, and there are often demonstrations. Don't you panic when you say your life is safe?
Chen Nuo smiled.
Anyone who is familiar with Chen Nuo knows that Chen Nuo's smile means that he is angry.
Sure enough, the next sentence made all the foreign media change their colors.
When did I say that the lithium-sulfur battery will be authorized for use by you in Korea?Did you get it wrong?
I will not authorize not only Korea, but also other foreign battery companies!
One sentence made all the netizens who watched the live broadcast happy and sad.
Domestic automobile and new energy vehicle companies are overjoyed, which means that lithium-sulfur batteries will be licensed to them, otherwise this technology will be useless.
Foreign car companies and new energy car companies have completely changed their colors. It is hard for them to imagine Chen Nuo making such a decision.
The emergence of lithium-sulfur batteries in Xiaguo will definitely break the industry structure of batteries and automobiles in the whole world.
As long as the energy density of lithium-sulfur batteries continues to increase, under the pressure of carbon neutrality, most of the world's car companies will go bankrupt, including luxury cars like the Golden Man.
Professor Chen, the emergence of lithium-sulfur batteries belongs to the world, and it will reduce the carbon emissions of the entire world, which is crucial to the global climate impact.
Professor Chen, you should give up your prejudice against foreign countries and share the achievements of lithium-sulfur batteries.
Professor Chen, are you sure you want to give up such a big foreign market?
You are a monopoly, we ask the WTO to file a case for a thorough investigation!
Chen Nuo, have you ever thought about how many foreign auto companies will go bankrupt if you do this?How many people will lose their jobs?How much turmoil will it cause to society?You are acting irresponsible.
A number of foreign media and foreign car companies in charge of Xia Xia all stood up and accused Chen Nuo one after another.
That kind of expression made all Xia people extremely angry, and the scene was chaotic.
