Chapter 323 Lithium-air battery performance test
At 55:[-], Qin Yuanqing, Principal Chen and Director Ye came to the laboratory together.

What appeared in front of them was a cylindrical battery with a diameter of about five centimeters and a length of about ten centimeters.

"The first charging experiment of lithium-air battery starts now!"

Qin Yuanqing checked the time, it was exactly three o'clock, so he ordered the first charging experiment to start, and a researcher pressed the charging button.

The charger with a charging power of up to [-]kW began to beep slightly, and on the invigilation screen beside it, the power reading in the lithium-air battery was rising rapidly.

10Wh.

20Wh.

50Wh.

Director Ye asked: "Academician Qin, how long will it take to charge?"

Qin Yuanqing smiled and said: "The weight of this round battery is about 2Kg. Theoretically, the weight can reach more than 5kWh. I estimate that it will take at least two or three hours to fully charge it."

Two kilowatts of power supply for two or three hours, think about it is a terrible data.

This means that the energy density of this lithium-air battery is equivalent to ten times the energy density of the current best lithium battery, which is completely enough to subvert the current energy structure!

No one in the lab spoke, and everyone was staring at the readings on the screen.

They all know how terrible the battery they manufactured will be. Its appearance will subvert the existing battery field. Lithium batteries will be replaced by it. In the future, mobile phones and computers will be replaced with the same The volume of the lithium-air battery can last for dozens of hours or hundreds of hours.A battery of the same size as a battery car can last six to seven hundred kilometers on a full charge.

Now the new energy vehicles that have been on the road, the same battery pack, will have a range of three to five thousand kilometers, which will completely promote the development of new energy vehicles.

And it is such a great product that was born in their hands.

one hour two hours.
At 48 hours and 2560 minutes, the alarm beeped when the charging was completed, and the reading on the screen finally stayed at [-]wh.

In the laboratory, there was thunderous applause, and some researchers even shed tears of excitement.

After everyone celebrated, Qin Yuanqing pressed his hand and said, "Everyone be quiet, there are still a series of experiments to be done!"

"And judging from the current data, it is far from the theoretical value, which means that this lithium-air battery still has great potential to be tapped, and everyone has a long way to go!" Qin Yuanqing said.

Everyone calmed down, as Qin Yuanqing said, the theoretical specific energy of this lithium-air battery can reach 5.21kWh/kg in the presence of oxygen, and a 2kg battery is supposed to have 10420kwh, but now it is only 2560wh, which has just reached four One-third, which means that the potential of the battery still has a lot of room to be tapped.

And although the current lithium-air battery has excellent performance, it is only the first charging experiment, and there will be a series of tests such as discharge test, safety test, open circuit voltage test, etc. They are too happy now up.

However, most of the people had a subtle change in their mentality at this time, they had a look of admiration for Qin Yuanqing, and they thought it was right for them to return to China.

To be honest, there are hundreds of people in the laboratory at present, most of them are returning from overseas. They give up the superior life and familiar environment overseas, and come back to China. They have to re-acquaint themselves with the environment. They mustered up their courage to reacquaint themselves with an unfamiliar environment, and some of them managed to achieve it after many discussions with their wives.

But now that they have just returned, a great product was born in their hands, which filled their hearts with a sense of accomplishment.

If they are overseas, no matter how hard they try, they will never have their share in the research of lithium-air batteries.They want to participate, and many times cannot participate.

It is also a tragedy to say that many people go to study abroad with a yearning for overseas, and then stay overseas, but soon they will find that they are stupid and naive, and others are wary of them Just in case, they are unable to participate in the research of many frontier positions, which is a kind of distrust.

But returning to Huaxia is different. This is their home country, and not being able to guard against them is like guarding against thieves.

Everyone followed the procedure and started the discharge test. The discharge test used a [-]-kilowatt DC motor.

As a result, this lithium-air battery persisted for a long time before it announced that it was out of power, and this also proved that the power stored in it was not false.

"Academician Qin, congratulations to you and your team, you have indeed completed a great finished product!" Director Ye said to Qin Yuanqing, and then shook hands with the main technical backbone.

After these two tests were completed, Director Ye and President Chen left, and Qin Yuanqing asked the researchers to manufacture more standard lithium-air batteries for testing in various fields.

Originally, it was enough to manufacture 120 standard lithium-air batteries, but in order to speed up the test and accumulate more data, Qin Yuanqing manufactured a full [-] standard lithium-air batteries for testing in various fields.

Manufacture of this standard type of lithium-air battery is nothing more than spending some money. Other laboratories will follow the principle of saving if they can, but in Qin Yuanqing's laboratory, this problem does not exist.Because this little money is really nothing.

The funds of the two laboratories are incomparably sufficient.

In the next half month, the whole team carried out various tests while the iron was hot. After making corresponding adjustments according to the experimental results, it announced that this lithium-air battery was ready for commercial use.

Among them, when its charge and discharge times are more than 300 times, the capacity can still maintain more than 80.00% of the initial capacity.The working temperature is between minus forty degrees and sixty degrees, and modular design is possible.Moreover, the larger the mass and volume of a single lithium-air battery, the higher the energy density.

If it is made into the same size as the battery of the current mobile phone, basically the smartphone can be used continuously for a week without any problem. If it is used less frequently, charging once a month or two is enough.

If it is used in the new energy vehicle industry, it can easily break the current pattern of new energy vehicles. As long as the battery is sufficient, it is no problem that it can even last for more than [-] kilometers on a single charge.

Of course, the production cost of lithium-air batteries will be much higher than that of lithium batteries. Even after large-scale industrial production, the cost will be three times that of lithium batteries of the same volume.

However, the performance is increased by more than ten times, and the cost is three times, which is completely acceptable.

Moreover, with continuous breakthroughs in the production process of lithium-air batteries and various materials, the production cost of lithium-air batteries will be further reduced.

While carrying out a series of tests on lithium-air batteries, Qin Yuanqing was also participating in a multi-departmental meeting, in addition to the Ministry of Science and Technology, the National Development and Reform Commission, the Ministry of Ecology and Environment and other departments participated.

The meeting was presided over by a leader in person. Qin Yuanqing introduced the breakthrough progress of lithium-air batteries in scientific research, the basic performance of lithium-air batteries, and the impact on many industries such as the automobile industry and the electronics industry.

Of course, lithium-air batteries use the oxygen in the air to react, so they are not suitable for aerospace and aviation. After all, aerospace engineering goes to space, and without oxygen in the air, it is impossible to generate electricity at all. less than.

However, whether it is civilian or military, it will have a huge impact. It is conceivable that with the promotion of new energy vehicles, the amount of oil used will have a huge impact, which will greatly reduce the national energy dependence on oil. This is undoubtedly beneficial to national security.

Similarly, Qin Yuanqing also stated that after the lithium-air battery is put into use, Huaxia's power consumption will usher in an explosive growth. At present, Huaxia's power generation is not enough to cope.

The leaders of various departments listened carefully to Qin Yuanqing's introduction and took notes from time to time. The ministries and commissions that can participate in this meeting are closely related to lithium-air batteries, which will affect their subsequent policy formulation.

During the period, the leaders of various departments continued to consult, and Qin Yuanqing explained impatiently.This joint meeting lasted for three days.

It's just that there is no news from the outside world, and all walks of life will not realize that their industry will usher in an earth-shaking change. This time, the big change will exceed any previous one and involve many fields.

At the same time, it was also finalized at the meeting that China Great Wall and Narcissus Times will produce lithium-air batteries, while Qin Yuanqing's laboratory will only charge patent licensing fees, and the patent licensing fees have also been finalized. Charged at 10000% of production cost.

Originally, the meeting only decided on the Great Wall of China, which is a state-owned enterprise after all, but Qin Yuanqing tried to increase the Narcissus Era based on reason. After all, the Narcissus Era is in his hometown, so he has to take care of it no matter what, for the benefit of his hometown.

Of course, you can’t say that in a clear way, but one state-owned enterprise and one private enterprise will create competition, so as to avoid the lack of competition and eventually form a pool of stagnant water.

In the end, according to Qin Yuanqing's intention, the Narcissus Age was added.

"Academician Qin, you and your team are amazing. The lithium-air battery you have developed has given me full confidence in China's revival and the goal of carbon neutrality!" A leader shook hands with Qin Yuanqing, full of admiration.

"Leader, it's thanks to the country providing us with a peaceful and good research environment, otherwise we wouldn't be able to do scientific research with peace of mind!" Qin Yuanqing said shyly.

"The renaissance of China requires the joint efforts of all Chinese people in various fields, and put our efforts together. I think we all have a firm heart to realize it." The leader said in an approachable manner.

Qin Yuanqing has always been steadfast in the great goal of China's revival, and has strong confidence. No one can stop it. If anyone tries to stop it, then use the great power of science and technology to prove that all attempts to stop China's revival are delusions. They will all be crushed into powder by the general trend of history.
