In the field of batteries, there are many technical routes.

In the field that He Ting understands, there are several solutions to deal with different scenarios.

And in many scenarios, security is a top priority.

In terms of safety, all-solid-state batteries are a battery technology that is currently visible and promising in the near future.

At this moment, hearing that Gu Tao said that the technology of all-solid-state batteries had been developed, He Ting couldn't help but be overjoyed.

Regardless of the cost of the industry, there are some design ideas that can be tried in some key places.

"Is he willing to share the technology?" He Ting asked.

Gu Tao nodded and said, "Yes, he took the initiative to call, naturally this is what he meant." I am afraid that it is not only technology, but also how to use this technology to strengthen the competitiveness of some industries. He said that in this project, Huawei invested a lot of money, and the layout direction is electric vehicles. Have you deduced what level this technological breakthrough is?"

He Ting became more and more surprised, explained the concept and advantages of all-solid-state batteries, and then said: "Normally, this battery technology is first applied in micro electrical appliances and other fields, and then evolves to consumer electronic devices such as mobile phones, and finally can reach the automotive field that supports power batteries." If he calls Warwick's Ren Zhengfei now, it means ...... Perhaps he has made a breakthrough in the battery preparation process and material architecture. This is a technological breakthrough that rewrites the battery industry and even many electronics industries!"

Gu Tao thought for a while, and then said: "I will immediately arrange to gather some experts in related fields to analyze them in advance." Understand the current technical route, the progress of foreign countries on each route, and analyze the strategies we can adopt. Over there, you should also bring in the relevant engineers. ”

Because of Gu Song's phone call, some people were temporarily summoned and gathered towards Shuhai.

……

Ren Zhengfei is already on his way to Yanjing,

He had been waiting for this day for a long time.

As a strategic partner of Huawei electric vehicle business, Flint Technology has provided some technical support in the past.

Including on-board sensors, on-board chips and intelligent operating systems, artificial intelligence applications......

But as a car, power and safety are always the most important considerations.

And the use of the current lithium battery, power and safety, there are hidden concerns!

As a result, Warwick's electric car is currently considered a concept car, just like other major car manufacturers.

No, people have also earned a lot of gimmicks at various auto shows by virtue of their accumulation in model design.

Warwick's electric car is still only in the prototype stage of internal secret testing!

He agreed with Gu Song's opinion.

As a newcomer in the automotive field, Huawei should reflect more differences when launching its first generation of products.

It is necessary to make consumers feel that it is indeed because of completely different thinking, using different concepts and technologies, that it is not a car in the traditional sense.

As a result, the vehicle's driver assistance system and even autonomous driving capability are constantly being optimized, as well as battery management and power delivery technology.

Gu Song made a phone call and said that the battery technology was done, so Ren Zhengfei was like drinking sweet springs, and immediately adjusted the arrangements and flew to Yanjing.

"You said that the distance will be farther than that of a car?" Ren Zhengfei asked the technical director of the electric vehicle project.

"The core challenges of low ionic conductivity and high interfacial impedance of all-solid-state batteries are that must be faced. The technical director lifted his glasses and was a little worried, "If you just achieve good data in the laboratory, but the preparation process is too demanding or too costly, it will take a long time to improve." After all, we are a commercial project, and economic considerations are a must. ”

Ren Zhengfei stared at the long-term and said calmly: "A breakthrough is good." What are the most difficult points of these two core problems?"

"The material problem of solid-state electrolytes!" blurted out the technical director, "Solid-state electrolytes are designed to solve the process structure defects and safety problems caused by liquid electrolytes, but their conductivity and interfacial impedance are worse than those of industrial electrolytes. Of course, this refers to the comparison of the technical route of existing solid electrolytes with mature liquid electrolytes. If they find excellent solid-state electrolyte materials and low-cost mature processes, then the basis for using solid-state batteries in electric vehicles will exist. ”

He sighed and said, "But it's too difficult! Now, it's hard to get the capacity of a solid-state battery to the mAh level, let alone the Ah level required for electric vehicles." ”

Ren Zhengfei thought for a while and said: "I remember I heard you say before that Mr. Gu makes solid-state batteries, and his own rover will also be a big application direction." In your judgment, with him joining in and promoting the development of the solid-state battery industry chain, what is the time expectation for the capacity increase and cost reduction of solid-state batteries?"

The technical director smiled bitterly: "I really can't judge, because I haven't got the technical data they have made now." It can only be said that with the promotion of giants at the same time, the time expectation will be much better, and the probability of winning this technical route will be much greater. But Mr. Ren, when you say that, I think he may be doing the solid electrolyte material route of the oxide system. The imagination of flexible batteries in the field of consumer electronics is too great. If it's an oxide system, then we have to wait for electric vehicles. ”

Ren Zhengfei's expression remained unchanged.

The place for discussion and exchange is set up in an external conference room of the Flint Research Institute.

All three aspects are valued, and those who can arrive at the first time are here.

There is no need for Gu Tao to be there in person, and He Ting is the same, they are led by Gu Song's acquaintance: Professor Cui, an economist who also serves as a director of the Cultural Development Center.

There are only three people on Ren Zhengfei's side, he, Tong Yueting, the female CEO of the electric vehicle project, and the technical director.

Gu Song's side is himself, Wang Suizhen of the Materials Institute, and the heads of the two cooperative institutes involved in the project.

After the greetings, Professor Cui said: "We have analyzed it before coming, and now we will look at the specific technical indicators and process solutions." Mr. Gu, I will listen to your discussion first, and then make a comparative analysis of the industry situation. ”

Gu Song smiled and nodded at him, then looked at Ren Zhengfei again, and said lightly: "In this breakthrough, the modeling of quantum computers and artificial intelligence have played a big role. In essence, we have found a lot of materials, and the breakthrough is not small. ”

Wang Suizhen also played the information on the display screen quite impressively.

The technical director brought by Ren Zhengfei and the technical experts who came with Professor Cui opened their eyes wide and looked at the chart above.

"Polymer ...... Oxide...... Sulfide...... This...... Are these data true? Can this kind of conductivity be achieved at room temperature?"

"How did the interface impedance drop so low?"

"The conditions under which this sulfide produces H2S harmful gases are so harsh?

……

The technical director of Huawei's electric vehicle project did not exclaim directly like the experts who came from Shuhai, but he couldn't help but whisper to Ren Zhengfei and Tong Yueting excitedly: "The solid-state electrolyte of sulfide is the most suitable all-solid-state battery solution for electric vehicles." If the safety of this material is so high, and the energy density has far exceeded that of today's batteries by more than 400 watt-hours per kilogram, then you only need to look at the battery preparation process and evaluate the cost!"

Professor Cui's head was big: "Mr. Gu, all of a sudden...... There are so many breakthroughs?"

Gu Song smiled: "Yes, it is because there are too many fields that can be applied that I asked the patriarch for help." It's not my own business or Mr. Ren's company to build a competitive advantage on a certain product. This is a matter for the battery industry and the industries related to it, to set new standards. There are many fields involved, and today is certainly only the first round of discussion. ”

Professor Cui smiled bitterly: "I'll make a phone call first, it's not enough for me alone, it's too wide!"

Ren Zhengfei smiled at the corner of his mouth and threw a meaningful look at Gu Song.

With a mature solution and a country coming forward, the solid-state battery will mature as quickly as possible, even as an attractive new industry bait within the framework of HSDA.

capacity, cost, supporting industrial chain system...... The process of transforming technology into economic benefits requires enough time.

Relying purely on the market itself, the competition between innovative forces and traditional giants will always consume a lot of time and cost.

But if you bring a higher level of power, it's different.

Most of the participating countries of HSDA are simply unwilling to fall too far behind in the future. For them, space development and space city are too far away, so it is better to take the big ship of China's development, get rid of the crisis, and achieve development.

And Huaguo naturally understands this, and naturally hopes to have one more industrial link, which is a new opportunity for the upgrading of the entire industry!

Win-win!
