MTL - Rebirth: Fight For Life-Chapter 687

   Chapter 687

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

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

   And in many scenarios, safety is the top priority.

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

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

  No matter what the cost of the industry will be, in some key places, some design ideas can be tried.

   "He is willing to share the technology?" He Ting asked.

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

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

Gu Tao thought about it for a while, then said: "I will arrange it immediately, call some experts in related fields, and analyze it in advance. Understand the current technical route, the progress of foreign countries on various routes, and analyze the strategies we can adopt. Your side , and also invite the relevant engineers.”

  Because of a phone call from Gu Song, some people were temporarily summoned and gathered to Chuhai.

  …

  Ren Zhengfei is already on his way to Yanjing,

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

   As a strategic partner of Huawei's 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.

   With the current lithium battery, there are hidden concerns in terms of power and safety!

   This makes Warwick’s electric cars, like other major automakers, currently considered concept cars.

  No, they also made a lot of gimmicks at various auto shows with the accumulation of model design.

  Huawei's electric car is still in the prototype stage of internal confidential testing!

   He agreed with Gu Song's view.

  Huawei, as a newcomer in the automotive field, has to show more differences when launching its first-generation products.

   must 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.

   Therefore, the assisted driving system and even the driverless capability of the car are constantly being optimized, as well as the battery management and power output technology.

  Gu Song called and said that the battery technology was done, so that Ren Zhengfei was drinking like a spring, and immediately adjusted the arrangement and flew to Yanjing.

   "You said that it is still far from being applied to automobiles?" Ren Zhengfei asked the technical director of the electric vehicle project.

"The core problems of low ionic conductivity and high interface impedance of all-solid-state batteries must be faced." The technical director raised his glasses and was a little worried, "If only good data is achieved in the laboratory, but the preparation process If the requirements are too strict or the cost is too high, it will take a long time to improve. After all, we are a commercial project, and economic considerations are necessary.”

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

"The material problem of solid electrolytes!" the technical director blurted out, "Solid electrolytes are designed to solve the structural defects and safety problems brought by liquid electrolytes, but their electrical conductivity and interface impedance are worse than those of commercial electrolytes. Of course, this is all It refers to the comparison of the technical route of the existing solid electrolyte with the mature liquid electrolyte. If they find an excellent solid electrolyte material and a low-cost mature process, then the basis for using solid-state batteries in electric vehicles will exist.”

   He sighed and said, "But it's too difficult! Now, it is difficult to achieve the mAh level of solid-state battery capacity, let alone the Ah level required by electric vehicles."

Ren Zhengfei thought about it and said, "I remember hearing from you before that Mr. Gu makes solid-state batteries, and his own rover will also be a great application direction. In your judgment, he will join in and promote the solid-state battery industry chain. What is the expected time for the capacity improvement and cost reduction of solid-state batteries?”

The technical director smiled bitterly and said: "I can't judge, because I haven't got the technical data they have made. It can only be said that if there are giants pushing at the same time, the time expectation will be much better, and the probability of winning this technical route will be much higher. .But Mr. Ren said 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 big. If it is an oxide system, then we will make electric For the car, you have to wait."

  Ren Zhengfei's expression remained unchanged.

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

  We attach great importance to all three aspects, and everyone who can arrive at the first time has come.

   There is no need for Gu Tao to come in person, as does He Ting. They were led by an acquaintance of Gu Song: Professor Cui, an economist who also serves as a director of the Wenfa Center.

   Ren Zhengfei has only three people here, he, Tong Yueting, the female CEO of the electric vehicle project, and the technical director.

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

After the    greeting, Professor Cui said: "We have analyzed it before coming here, and now we will look at the specific technical indicators and process plans. Mr. Gu, I will listen to your discussion first, and then compare and analyze the industry situation."

Gu Song nodded to him with a smile, then looked at Ren Zhengfei again, and said easily: "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 achieved The breakthrough is not small.”

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

   The technical director brought by Ren Zhengfei and the technical experts who followed Professor Cui opened their eyes wide to look at the chart above.

   "Polymers...oxides...sulfides...this...is this data true? Is it possible to achieve such conductivity at room temperature?"

   "How did the interface impedance drop so low?"

   "The conditions for this sulfide to produce H2S harmful gas are so harsh? Isn't that almost safe?"

  …

The technical director of Huawei's electric vehicle project did not exclaim directly like the experts from Zhuhai, but he couldn't help but whispered to Ren Zhengfei and Tong Yueting with excitement: "Sulfide solid electrolyte is the most suitable for electric vehicles. All-solid-state battery solution for automobiles. If the safety of this material is so high, and the energy density has far exceeded the current battery of more than 400 watt-hours per kilogram, then we 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 so many applicable fields that I ask the veterans for help. This is not about my own company or Mr. Ren's company, establishing a competitive advantage in a certain product. This is The battery industry and related industries, the establishment of new standards. There are many fields involved, and today is definitely only the first round of discussions.”

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

   Ren Zhengfei smiled and cast a meaningful look at Gu Song.

  Solid-state batteries have mature solutions, and the country has come forward, and even as an attractive new industry bait in the framework of HSDA, this industry will mature as quickly as possible.

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

  Relying solely on the market itself, 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 will be different.

   HSDA participating countries are mostly just unwilling to be too backward in the future. For them, space development and space city are too far away. It is better to get on the big ship of China's development, get rid of the crisis and gain development.

   And Hua Guo naturally understands this, and naturally hopes to have one more industrial bond, this is a new opportunity for the entire industry to upgrade!

  Win-win!

   Thank you Dashan Dashan for being so stupid and every time you change your nickname, you have to give a reward of 10,000 points!
