For the gift, start research and development of graphene batteries

Chapter 86 Carbon-Based Battery Conference

Due to the preheating of the publication of the carbon-based battery paper, coupled with the publicity of many media, the entire industry paid extra attention to this conference.

Numerous media and enterprises have submitted applications for participation.

Due to too many applicants, even if Wang Mingyang changed the meeting place to a larger venue, it still couldn't meet the needs of the increasing number of people.

There is no way, Wang Mingyang can only arrange personnel, verify the applicants, and give priority to selecting some enterprises with strength and background.

Just like that, after a few days of wandering, the new product launch event, which had been publicized for a long time, officially opened.

It can be said that this press conference brought together more than 80% of the companies in the new energy industry, which can be called a grand event of the new energy industry.

In this press conference, Wang Mingyang originally asked Jiang Ming to participate, and then gave a keynote report.But after thinking about it again and again, Jiang Ming shirked it.

The so-called big tree attracts the wind, and there are many popular people. Jiang Ming felt that he had gone too high and was not used to it.

At Jiang Ming's age, it is not easy to reach this level.Jiang Ming felt that it was unnecessary to release new products in front of the entire industry and countless eyes.

Moreover, although Jiang Ming led the development of carbon-based batteries, how to put it, it should be said that the New Energy Industry Association used Jiang Ming's strength to amplify the advantages of the industry.

Although Jiang Ming's contribution is great, the industry association should be put in the first place.

Therefore, Jiang Ming felt that Wang Mingyang, the vice president of the association, was the most suitable for the keynote speech.

In the end, Wang Mingyang followed Jiang Ming's advice and came to the stage to give a speech in person.

As for Jiang Ming, he had more important things to do.

WIDC World Intelligent Driving Challenge?
Looking at the information sent by Qin Ruya in the mailbox, Jiang Ming was thoughtful.

WIDC is an intelligent driving technology challenge that has emerged in recent years, aiming at evaluating intelligent driving technology.Set a benchmark for the industrialization of autonomous driving technology.

Since its inception, this competition has attracted many enterprises to participate.In particular, many new car-making forces are eager to participate.

According to Qin Ruya's news, for next year's competition, Xia Ke Academy will also arrange personnel to participate.Otherwise, the technology of autonomous driving will be completely turned into a laboratory product, and there will be no chance to go to the market in large quantities.

As for such an important event, Jiang Ming was not expected to be invited to participate.

Could it be that the email I left before leaving really played a role?

Forget it, when you see Qin Ruya, ask her clearly.

Jiang Ming is also very interested in this competition.

Jiang Ming felt very regretful after studying the books on automatic driving for so long, and finally obtained the inheritance.

This time, taking the opportunity of the competition, it is the best to develop a complete automatic driving system.

It's just that I don't know if the people Qin Ruya arranged can keep up with Jiang Ming's thinking.

You know, after the inheritance, Jiang Ming is not at the same level as before in the field of automatic driving.

According to Jiang Ming's way of thinking, since he wanted to participate in the competition, he had to come up with extraordinary products, and Jiang Ming really didn't like it.

If Qin Ruya doesn't believe in herself, then it's a bit difficult?
Could it be that they want to grab the command?This is not in line with Jiang Ming's style of doing things.

Forget it, let's think about how to prepare for the event first.

Although there is still some time before the opening of the competition, there are many things that need to be prepared. Jiang Ming also seized the time to study the materials.

While thinking, Jiang Ming opened up the thick technical requirements for the competition and began to study.

Compared with Jiang Ming's calm and relaxed mind, at the press conference of carbon-based batteries, the group of international lithium battery giants led by Buston Company couldn't sit still.

Their worries came true. Xiaguo's company not only developed a new generation of lithium batteries, but also industrialized carbon-based batteries in a very short period of time, reaching the conditions for mass production.

This speed is far beyond everyone's imagination, and it also violates the basic time cycle of scientific research.

Could it be that Xia Guo has been studying carbon-based batteries for a long time and has been using them secretly, but only recently has the corresponding technology been released?

It seems that there is such a possibility.

After all, it was the lithium battery giants who felt the threat of graphene batteries, joined forces to control lithium carbonate materials, and tried to force Xiaguo Enterprises to share graphene battery technology, and then this kind of thing happened.

If this is the case, then it will be a big deal. It is not certain whether Xiaguo Enterprise has other technologies.

In the past, when graphene batteries were used, they could manipulate lithium carbonate batteries to force Xiaguo enterprises to submit. In the era of carbon-based batteries, what other means are there?

It is impossible to monopolize the copper mines. This seems unrealistic. The output of copper mines is so large that not a few companies can handle it.

Moreover, although the lithium battery industry uses a lot of copper resources, it is still far from enough compared with other large players.Several enterprises cannot be controlled at all.

For the diaphragm, if it is a few years earlier, it may be a breakthrough.But now that the local diaphragm factory in Xia Kingdom has started up, no matter how much you want to suppress it, you can't suppress it anymore.

The big guys thought about it for a while, but they didn't feel that they had any good ideas.

This feeling is extremely uncomfortable.

What is even more uncomfortable is that all enterprises will be restrained in the future, otherwise the development of the country's industry will come to an end.

On the platform, Wang Mingyang was giving a keynote report:
"According to our measurements, the energy density of carbon-based batteries is expected to reach 2500Wh/kg. For family cars, the cruising range of a single charge is expected to reach 5000km according to calculations."

Even though they knew this data from the paper, everyone gasped when they heard this parameter on the spot.

Carbon-based batteries have definitely subverted people's understanding of lithium batteries. With such performance, what's the use of a petrol car?

Some people also said before that new energy companies are pseudo-environmentally friendly, and they are good at polluting things under the guise of environmental protection.

Because the production of lithium batteries is very polluting, especially the production of electrolyte and the preparation of positive and negative electrodes, the pollution to the environment is very serious.

What's more serious is that after the battery is scrapped after 8 years of use, the pollution of its scrap products is also a problem that cannot be ignored.

Although lithium batteries do not contain heavy metals such as lead, they claim to have no pollution to the land and can be thrown directly into the ground.

But it’s okay to throw one or two. If you throw too much, there will definitely be pollution.

Moreover, although many lithium batteries have reached scrapping, this scrapping is not the kind of scrapping that is completely unusable in the traditional sense.

It is because the remaining available power of the battery is running low, and sufficient cruising range cannot be guaranteed.

The battery is still charged and still dangerous.

Regarding the disposal of these scrap batteries, if one is not careful, there will be a safety accident.

In fact, the problem of the above-mentioned battery, in the final analysis, is that the performance of the battery cannot meet people's requirements for performance.

Graphene batteries, at present, seem to be able to solve this problem.

The most polluting parts in the battery, the positive and negative electrodes and the electrolyte, have been greatly improved, and the environmental protection has been greatly improved.

The electrolyte has been changed from a traditional liquid to a gel state, and the corresponding environmental protection has been greatly improved.

In addition, the positive and negative electrode materials use the latest graphene technology to build a huge contact area on the microscopic level, reducing the use of lithium carbonate and further reducing the pollution of the battery.

Moreover, due to the huge energy density of the battery, the utilization of electric energy in the grid is also more stable.

Traditional lithium batteries, due to the pursuit of excessive charging speed, make the power grid fluctuate very frequently.

If it is one or two cars, this kind of fluctuation may not be a problem for the grid.But when tens of thousands of cars are charging at the same time.The huge surge voltage will cause a great impact on the power grid and power equipment.

If the battery can be charged more stably and for a long time, although the load on the grid is maintained at a high level, the impact on the equipment will be smaller.

The 5000-kilometer battery life can make car owners feel more at ease when using the car, and there is no need to keep staring at the mileage of the vehicle to completely solve the problem of battery life anxiety.

Many things, when the quantity reaches a certain value, will cause qualitative changes.

This is the case with carbon-based batteries. With a battery life of 5000 kilometers, carbon-based batteries will definitely be applied to new areas.

"More importantly, although our carbon-based battery has a voltage platform of 3.65V, which is consistent with the ternary battery, its safety is better than that of lithium iron phosphate battery."

Wang Mingyang continued to add.

Speaking of this, everyone was stunned, because there was no such data in the paper.

In the paper, it is only stated that the safety of carbon-based batteries has been greatly improved, without specifying to what extent.

Reminiscent of the astonishing energy density of carbon-based batteries, according to everyone's speculation, its safety will definitely be compromised.Who would have thought that this conclusion was reached at the press conference today.

Is it possible to have better safety than lithium iron phosphate batteries?Could it be Wang Mingyang talking big?
At this moment, even Xia Guo's colleagues couldn't help feeling suspicious of Wang Mingyang's words.

You know, in the lithium battery industry, we all know a truth: the energy density and safety of batteries cannot have both.

A higher energy density means that the chemical properties of the battery are more active, and the corresponding safety will be reduced simultaneously.

Now everyone has actually heard this conclusion. If Wang Mingyang hadn't said it, everyone would have started complaining.

The general practitioners have this kind of skeptical look, not to mention the lithium battery giants sitting in the front row.

Some people even laughed lightly, despised by Wang Mingyang's big words.

Regarding the commotion in the audience, Wang Mingyang ignored the commotion, but gave everyone time to discuss. When the discussion was almost over, Wang Mingyang said:
"Next, I'll show you a video."

Then, on the huge screen in the lecture hall, the picture of the carbon-based battery doing the acupuncture test appeared.

The thick copper needle pierced the carbon-based battery, but the carbon-based battery only emitted white smoke for a while, and then the white smoke went out.

The carbon-based battery was pierced in this way, and it lay there quietly without any movement, and even the white smoke was completely gone.

If it weren't for the thick copper needle, no one would have believed that this was an acupuncture test.

This!
What's the situation, why the acupuncture test didn't respond, it can't be a fake battery, right?Someone saw the amazing performance of carbon-based batteries and said so.

It's just suspicion, but the equipment connected in the video clearly shows that the battery has voltage and is a real battery.

"Look, the voltage of the battery dropped sharply after the acupuncture test, and now it has dropped to a few tenths of a volt."

A sharp-eyed person spoke like this.

Everyone quickly looked at it, not to mention, this is really the case.

There was voltage before, but after acupuncture, there was no voltage, which is a bit strange.

Generally speaking, after the acupuncture test, as the internal short circuit of the battery proceeds, the voltage of the battery cell gradually decreases until it is finally zero.

Now the battery is emitting a little smoke, the temperature has not risen much, and the battery voltage is zero. Does this mean that the battery has no energy?
It seems that this possibility is really possible, just like the energy of the battery is completely released in an instant.

But the energy of the battery is there, and there is no huge reaction of fire and smoke, and the energy of the battery will not disappear for no reason.

If you think about it this way, there should be something that prevents the chemical reaction inside the battery cell, locking the energy of the entire battery and never releasing it.

Some technical experts analyzed it like this.

Many people obviously thought of this too.

If carbon-based batteries are really capable of controlling the release of battery energy, then there is really a solution to the problem of battery fire.

Thinking of this, everyone looked solemn. This point is really important. With this method, new energy sources can basically say goodbye to battery fires.

"In carbon-based batteries, we innovatively use trinity technology to minimize the risk of thermal runaway."

"At the moment of thermal runaway of the battery, including the electrolyte,

Many components, including the battery separator, can effectively prevent the spread of thermal runaway and control the risk of thermal runaway at a single point. "

Wang Mingyang briefly introduced the measures for thermal runaway of carbon-based batteries.

Of course, Wang Mingyang said very briefly. After all, it involves the core secrets of carbon-based batteries, and Wang Mingyang can't say too much.

Although Wang Mingyang said it very briefly, everyone understood it. Sure enough, as everyone thought, carbon-based batteries can precisely control the point of thermal runaway and prevent the spread of thermal runaway.

In other words, even if the battery has thermal runaway, it will only be controlled at a certain point of a battery, and it cannot even spread to the surface.

This kind of technology is simply unheard of.

No matter what, this control technology is great news for the entire lithium battery industry, and everyone is very excited.

Compared to other practitioners, the international giants are a little confused. What is the situation? Have we crossed over? Why is Xia Guo's technology so much ahead of them all of a sudden?

Fortunately, Xia Guo's colleagues were still hiding their clumsiness before, and they looked like they wanted to ask for advice. Is this all a lie?
