Chapter 578 Solid-state batteries

On this trip, Jian Yushu also needs to go together. In addition, a tube oak is added.

During the special period, Zhao Hongtao was still responsible for the security arrangements on Yanjing's side, and he needed to stay on guard against possible enemies.

Bao Jiaqi led the team, and the entire delegation chartered a 747. The first stop, direct flight to Australia.

The flight was very long, and Gu Song was also arranged by Bao Jiaqi to sit in his cabin area.

To Gu Song's great surprise, Liu Xi was also there.

That's right, he is now the chief officer of the Ministry of Commerce after all.

Of course, Han Jingwei is also there, and there are three other high-ranking officials.

On the side of the enterprise, in addition to Gu Song, Ren Zhengfei and Guo Wei, there are also two CEOs in the telecommunications field.

In the past, the export of communication technology was also an important task.

In addition, there are two energy bosses and two steel bosses.

Although they sat in the same cabin, they only knew each other and exchanged pleasantries.

When Liu Xi shook hands with him, he was smiling and looked very close.

Gu Song, Ren Zhengfei and Guo Wei sat together, whispering.

"I heard a friend in Huhai say that you want to build a larger chip factory in Huhai?"

Guo Wei asked, and Ren Zhengfei also whispered: "It's mysterious, I heard that it is the next generation of chips, what are the new breakthroughs?"

Gu Song shook his head: "Plan ahead, plan first." How's the progress of your Wuhu factory?"

Guo Wei and Ren Zhengfei, you look at me, I look at you, and then ask Gu Song: "What do you say?"

“…… Don't be suspicious, I just care. ”

Guo Wei said: "I have been staring a lot about the docking of smart cities in Wuhu recently. The current progress is according to plan. But at the end of the year, it will be time to enter the production line layout inside the plant. How it will be produced in the future, there is no spectrum. ”

Gu Song looked at the front and back: "Let's talk later." Rest assured, push as planned. ”

Ren Zhengfei didn't have such a struggle, he did make cars there anyway, and there were some things that he could start doing first.

It is...... He couldn't help but ask: "...... battery technology"

Gu Song could only continue to nod: "Don't worry." ”

They are all people who control a super-large enterprise, and this feeling of being controlled by others at some point is really delicious.

If it weren't for Gu Song's past achievements being too brilliant, and the prospects in these two fields were too tempting, Ren Zhengfei and Guo Wei would really not do this.

But in fact, because of the emergence of artificial intelligence, both have benefited in the past six months.

In Mingli, Digital China has won a big cooperation with Wuhu to build a smart city pilot, and Huawei can't do the order now because of the high requirements of artificial intelligence for network communication foundation.

In secret, both of them were the first to be laid out. Just like Warwick, even if there is no shadow of electric vehicles now, the software control system of the vehicle has shown excellent capabilities in quiet tests.

Indeed, as Gu Song said, this is a car of the future, a completely different scenario, and there is hope to change the standard of the industry.

Now, the technology to build a car is not too difficult, at least not for Warwick.

The addition of sensors and intelligent vehicle control systems to vehicles is not a problem.

But what has to do with motivation is the difficulty.

What is the performance of the battery, how long can it last, and how efficient is the charging......

After all, the car is meant to run.

The plane entered a smooth flight phase with a long range. After a while, many people entered a state of resting with their eyes closed.

In Gu Song's mind, the task was running in his sleep.

Actually, when it comes to the issue of batteries, it is not complicated to say that it is complicated.

At the end of the day, it's a matter of cost at this stage.

The principle of this battery has not changed for decades, but it has been trying to increase the capacity and improve the charging and discharging efficiency.

The magnitude of the increase is extremely limited.

At least compared to the rapid evolution of integrated circuits, battery technology is still very "primitive".

One has entered the quantum level, and the other is still in the molecular stage.

It's like a lithium battery.

A general lithium battery solution, lithium cobalt oxide for the positive electrode and graphite for the negative electrode.

When charging, lithium cobalt oxide is stimulated, and the released lithium ions flow through the electrolyte to the graphite, forming an electric current. Graphite has many small holes that can accommodate lithium ions to pass through, and electricity is equivalent to "charging" into it.

When discharging, lithium ions swim back to the lithium cobalt oxide cathode through the electrolyte, which is the process of discharge.

The improvement over the years is nothing more than how to make enough lithium ions flow in the middle to achieve the purpose of expansion.

Here, the key is the selection of cathode and anode materials.

Lithium cobalt oxide and graphite are the most economical and efficient material partners that can be found today.

And discovering new materials has always been a very difficult thing.

This thing...... In the past, although there was some theoretical support, more often it relied on luck.

In particular, since it is to be used as a battery, it has to meet various requirements.

The energy density must be high, otherwise what is the use of making it?

The safety must be good, and the operation must be stable in the face of various environments, and it cannot be turned into a weapon without saying a word.

The life must be long, and the number of cycle charging and discharging must be enough, otherwise what is the battery called?

It has to be environmentally friendly......

The most important thing is that the cost must be low enough.

For example, there are people who do use gold for the positive electrode. So is this kind of battery exclusively supplied by local tyrants?

There are also those who think that since the swimming speed of lithium ions in the electrolyte is limited, can lithium ions swim directly through the air to the other pole? Although the idea of lithium empty batteries is good, it is basically regarded as a utopian dream.

Nuclear batteries are isotope decay batteries, a coin-sized nuclear battery can reach 1 million times the capacity of chemical batteries, the life can reach 5,000 years, and tritium batteries can also be used for 20 years.

But what about the downside? The cost is huge.

How difficult is it to find better battery materials, or even build entirely new battery architectures?

It is necessary to have a team that is proficient in materials science, inorganic chemistry, electrochemistry, solid state physics, engineering technology, as well as magnetism, neutron diffraction, infrared thermogravimetric nuclear magnetic resonance, synchrotron radiation X-ray, etc., and a team that is very good in the field of theoretical computing, so as to have a chance to make a breakthrough.

In the field of chemistry, because there are so many possibilities for permutations and combinations, a special discipline of computational chemistry was born.

But what about the ability? Predicting the reaction products of two molecules takes a whole day.

How many molecules need to be simulated inside a functional battery?

So, one of the most funny things about engaging in materials is. You have no idea why he succeeded, and you don't know why he failed.

One of the topics that Gu Song has been thinking about for a long time is how to achieve a certain degree of improvement in the current industrial technology.

Whether it is the cost-effective cathode and electrolyte materials at this stage, or the process improvement details of battery production, or the system of battery charge and discharge management.

For the problem raised by Ren Zhengfei, Gu Song is not without a solution.

It's this solution that looks ...... The technical content is too low.

The battery is strung into a battery pack, and through the optimal management of the system, there is a special sense of primitiveness that one firewood is not enough to burn and then add another firewood.

It's easy to let the car run two or three hundred kilometers, but Gu Song has many other things that also need batteries.

Energy black technology, even if you don't come up with a good one now, then at least you have to take a step forward, right?

For example, using his invincible computing power to find some positive and negative electrode materials that can be manufactured more economically, isn't it fragrant?

Or, all-solid-state batteries, doesn't it smell?
