Rebirth: Fight For Life

   Chapter 577 Solid State Batteries

   In this trip, Jian Yushu also needs to go together. Also, add a tube oak.

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

   Bao Jiaqi led the team, and the entire visiting group packed a 747. First stop, direct flight to Australia.

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

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

   is also right, he is now the head of the Ministry of Commerce after all.

   Of course, Han Jingwei was also there, along with three other senior 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.

   This trip to the past, outputting communication technology, is also an important task.

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

   Although they were sitting in the same cabin, they just got to know each other and greeted each other.

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

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

   "I heard a friend in Huhai say, 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 new breakthroughs are there?"

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

  Guo Wei and Ren Zhengfei, look at me, I look at you, and then ask Gu Song: "What's the point?"

   "...Don't be suspicious, I just care."

Guo Wei then said: "I have been watching a lot about the docking of smart cities in Wuhu recently. The current progress is according to plan. But by the end of the year, we will enter the production line layout inside the factory. How to produce in the future, there is no spectrum."

  Gu Song looked around and said, "Let's talk later. Don't worry, just push as planned."

  Ren Zhengfei didn't feel so entangled. He did make a car anyway, and there are some things that can be done first.

   is... He can't help but ask: "Battery technology..."

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

   They are all people who control mega-corporations. This feeling of being controlled by others at a certain point is really delicious.

   If it weren't for Gu Song's past record is too brilliant, and the prospects in these two fields are too attractive, Ren Zhengfei and Guo Wei would not have done this.

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

  In Mingli, Digital China got a big cooperation with Wuhu to build a smart city pilot. Due to the high requirements of artificial intelligence on the network communication foundation, Huawei cannot make orders now.

   In secret, both of them were the first to make arrangements. Just like Huawei, even if there is no shadow of electric vehicles, the software control system of the vehicle has already demonstrated its excellent capabilities in quiet tests.

   Indeed, as Gu Song said, this is a car of the future, it is a completely different scene, and it is hoped to change the industry standard.

   Now, the technology of building a car is not too difficult, at least not for Warwick.

  The newly added sensors and intelligent vehicle control system of the vehicle are not difficult.

   But things related to power are difficult.

  What is the performance of the battery, how long the battery life can be, the efficiency of charging…

  The car is for running after all.

  The plane entered a stable flight stage with a long range. After a while, many people entered a state of closing their eyes and resting.

  Gu Song's mind was running tasks in his sleep.

   Actually, the issue of batteries is complicated, but not too complicated.

   In the final analysis, it is the cost issue at this stage.

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

   The extent of improvement 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 at the molecular stage.

   is like a lithium battery.

  Universal lithium battery solution, lithium cobalt oxide is used for the positive electrode, and graphite is used for the negative electrode.

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

   When discharging, lithium ions swim back to the positive electrode of lithium cobalt oxide from the inside through the electrolyte, which is the process of discharging.

   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 choice of positive and negative electrode materials.

  Lithium cobalt oxide and graphite are the most economical and efficient material partners found now.

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

  This thing...Although there was a certain theoretical support in the past, it was more often based on luck.

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

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

   Better security, stable operation in the face of various environments, and can't be a weapon in disguise.

  Long life, enough cycles of charge and discharge, otherwise what is a battery called?

   Also have to be environmentally friendly…

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

  For example, someone does use gold as a positive electrode. So is this kind of battery exclusively for local tyrants?

   I also 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 lithium-air battery is a good idea, it is basically considered a fantasy.

  Nuclear battery is also known as isotope decay battery. The capacity of a coin-sized nuclear battery can reach 1 million times that of a chemical battery, and its lifespan can reach 5,000 years. 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?

One must be proficient in materials science, inorganic chemistry, electrochemistry, solid state physics, engineering technology, as well as many characterization and analysis methods such as magnetism, neutron diffraction, infrared thermogravimetric nuclear magnetism, synchrotron radiation X-ray, etc., and also be very good in the field of theoretical calculation. The team has only such a chance to make a breakthrough.

  In the field of chemistry, there are too many possibilities for permutation and combination, and a special discipline of computational chemistry was born.

   But what about ability? It takes a whole day to predict the reaction product of two molecules.

   How many molecules need to be simulated in a practical battery?

   So, the funny thing about making materials is. You have no idea why he succeeded or why he failed.

   One of the issues that Gu Song has kept in mind for a long time is how to achieve a solution that can be improved to a certain extent in the current industrial technology.

   Whether it is the positive and negative electrode and electrolyte materials with cost advantages at this stage, or the process improvement details of battery production, or the battery charge and discharge management system.

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

   That’s what this solution looks like…too low-tech.

   String the batteries into a battery pack and optimize the management through the system, especially the original feeling that one firewood is not enough to burn and add another firewood.

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

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

   For example, using your own invincible computing power, you can find some positive and negative electrode materials that can be produced relatively economically. Isn’t it delicious?

   Or, an all-solid-state battery, isn't it fragrant?
