Chapter 578 Solid State Battery
Solid state battery?
After hearing this term, Tian Hong couldn't help showing a hint of surprise. He didn't expect Zhou Fei to know this battery technology.

"Does President Zhou also know about the technology of solid-state batteries?" Tian Hong couldn't help asking.

The concept of solid-state batteries has just appeared not long ago. Tian Hong also saw similar reports in foreign journals, but in fact he only has this concept, and there is no real fruitful research.

Due to the high technical barriers and the lack of understanding of the working principle of solid-state batteries, let alone practical applications, there are not many theoretical studies. Lithium batteries are still regarded as a key research and development project internationally.

On the one hand, Tian Hong was surprised that Zhou Fei, a layman, knew the concept of "solid-state battery". On the other hand, he was worried that Zhou Fei proposed this concept. Could it be that he should let him develop this solid-state battery?

"I know a thing or two, but I don't think you know as much as Lao Tian." Zhou Fei replied with a smile.

It is different from the lithium-ion battery and lithium-ion polymer battery that are generally applicable now.Solid-state battery is a battery technology that uses solid-state electrodes and solid-state electrolytes. Its appearance is due to the scientific community's belief that the development of lithium batteries has reached its limit, and its power storage capacity cannot be broken through. The proposal of solid-state batteries, It is to replace the position of lithium batteries in the battery industry.

"That Zhou Zong meant that he wanted to replace lithium batteries with solid-state batteries?" Tian Hong asked with some uncertainty.

"Well, I have such an idea." Zhou Fei nodded directly, "I hope you can be in charge of this project. If this kind of battery cannot be used on the second-generation Tesla, then on the third-generation model, I hope to have a try, which is also a major selling point for Tesla in the future, to achieve new breakthroughs in battery life.”

Tian Hong looked at Zhou Fei with some embarrassment, and didn't know what to say for a while. Of course, the advantages of solid-state batteries are obvious. Due to the use of all-solid-state electrolytes, the applicable material system of lithium-ion batteries will also change. The most important point is that instead of using lithium-intercalated graphite anode, metal lithium is directly used as the anode.

In this way, the amount of negative electrode materials can be significantly reduced, so that the energy density of the entire battery can be significantly improved, so that it can conduct a larger current than lithium batteries on the premise of the same volume, and increase the capacity of the entire battery. The main principle of solid-state battery to improve cruising range.

At the same time, solid-state batteries also have the advantages of small size, flexible design, and safety, which are incomparable to lithium batteries.

However, these advantages only exist in theory at present. No one knows whether these advantages actually exist and how much these advantages can be exerted, and there is no experiment to prove them.

If Zhou Fei really wants to make solid-state batteries, then everything has to be done from scratch, not to mention the high investment cost, and the development cycle is also an unknown.

"What, is there a problem?" Seeing that Tian Hong was silent, Zhou Fei asked.

"There must be problems, but if Mr. Zhou really wants to develop solid-state batteries, then I can only obey orders." Tian Hong said bravely.

"Don't take what I'm saying as a ***. I didn't use a gun to force you to do it. If you have any difficulties, you can tell me now. I will definitely help if I can. If you can't do it, then let's do it again." Wait, I called you here this time just to discuss with you."

Zhou Fei said helplessly seeing Tian Hong's look of death.

"Boss Zhou is right, Lao Tian, ​​don't put on a sour face, report any problems immediately." Ma Huafu on the side also chimed in.

Although Ma Huafu doesn't know what a solid-state battery is, it must be a good thing if Zhou Fei can specifically propose it. If it can be developed successfully, it must be a good thing for Tesla.

"First of all, I won't talk about high development costs and long cycle times. Mr. Zhou should be very clear. I think the main problem is that the working principle of solid-state batteries is not very clear, and now I can't get away from it. Do too much theoretical research."

Tian Hong said with some shame.

It is not a wise choice to ask questions in front of the boss, and Tian Hong's reason sounds rather forced.

"In terms of working principle, I can try to find information for you. As for the time issue you mentioned, don't use this as an excuse in the future. Can't the lithium battery project on hand be handed over to other people? Don't tell me the battery pack You are the only one capable.”

Tian Hong scratched his head in embarrassment, "President Zhou said yes, I will definitely pay attention in the future."

"Okay, I'm not criticizing you. The solid-state battery project doesn't mean that it must be done right away. I just want to tell you in advance that you don't have to be too burdened. I will satisfy you. As long as there is time, other support will be satisfied as much as possible, you just feel free to do it, even if you fail, it’s okay.” Zhou Fei waved his hand in relief.

Even in Zhou Fei's previous life, solid-state batteries were only a theoretical product. Although Weilai once used solid-state batteries as a publicity gimmick when releasing a new car, which even caused a surge in Weilai's stock price, the solid-state battery Large-scale commercial use still has a long way to go.

Therefore, Zhou Fei didn't think about eating a fat man in this world.

"Understood Mr. Zhou, I must make a plan first when I go back, and try my best to complete the solid-state battery project." Tian Hong replied quickly.

Zhou Fei nodded, "Okay, then you go back first, the working principle you mentioned, I will look for you again in the next two days, I still have something to talk to President Ma."

"Mr. Zhou, how good is the solid-state battery you mentioned? Why does it sound so powerful? Even Lao Tian was too scared to pick it up." Just as Tian Hong left, Ma Huafu asked curiously.

"I won't talk about other things, but just one point, if the solid-state battery is really successfully developed, the cruising range of the vehicle will be increased to a level of [-] kilometers or even higher. What do you think is the advantage of solid-state batteries? "

"One thousand kilometers?" Ma Huafu couldn't help but open his mouth wide, which nearly doubled the existing cruising range!

"If that's the case, then we have to start this project. If Lao Tian doesn't want to, I have to develop this solid-state battery even if I force him with a gun!" Ma Huafu said with dancing.

If Tesla can take the lead in bringing the cruising range of electric vehicles to the level of [-] kilometers, it will definitely cause a huge sensation, and it will also be of great benefit to Tesla's development.

"It's not that exaggerated, Lao Tian should be fine." Zhou Fei smiled, and then asked again, "I heard that Ramsey is coming here?"
