Black technology: starting from ten thousand times faster

Chapter 59 Development of Solid State Batteries

In the new energy industry, there is a saying that has been circulating for many years - "The day when solid-state batteries become popular is when fuel vehicles will withdraw from the stage of history."

As long as a mature and mass-produced solid-state battery can be developed, it can completely subvert the automotive industry, making existing new energy vehicles completely uncompetitive, and making traditional fuel vehicles helpless.

And those who master this technology will become the overlord of the global energy industry, and can also radiate multiple industries through this technology, influence multiple industrial chains, and then affect the global structure, and have a very high social status.

However, the mass production of solid-state batteries still faces three huge difficulties.

First, solid-state batteries are a new technology. Due to changes in the material of the electrolyte and the production process, the entire production line has to be redesigned and adjusted, employees also need to be retrained, production specifications also need to be redesigned, and product quality control also needs to be proficient.

And these will inevitably lead to a substantial increase in production costs, making the originally extremely advantageous solid-state batteries lose their due competitiveness.

Second, the electrolyte and positive and negative electrode materials used in solid-state batteries are relatively new materials. The supply chain system is not perfect, and mass production has not been formed. Even some materials cannot find suppliers and need to be produced and processed by themselves.

Therefore, the production cost of each material may be very high, which will definitely increase the production cost of the battery and lead to loss of competitiveness.

Third, the fast charging efficiency is not good.

The conductivity efficiency of solid electrolyte is only about one tenth of that of liquid electrolyte, which can be simply understood as the charging efficiency is only one tenth of that of current new energy vehicles.

Among the three major difficulties, the first one is actually acceptable. After all, as long as the production line is adjusted, this cost is only temporary.

The most critical second and third difficulties.

These two major difficulties, in the final analysis, are all about materials.

To solve this problem, the best way is to develop a material with good electrical conductivity, while ensuring sufficient stability and safety, and not too difficult to obtain.

Su Xin's research in the past few days is to test the material ratio of various solid electrolytes.

And today, he finally had a breakthrough!
After testing, the conductivity of a sulfide solid electrolyte he just developed has reached 1.2x10-2S/cm, which is already comparable to that of liquid electrolytes. Coupled with the high energy density of solid-state batteries, it can fully meet the daily needs of new energy vehicles.

The most important thing is that the sulfide solid-state electrolyte originally envisioned by scientists has the huge disadvantages of poor electrochemical stability and poor air stability, which will lead to insufficient battery life, and may react with water or air to produce toxic substances, which poses a greater safety risk.

This is the biggest problem many companies are currently facing.

Now, Suxin has added several metal oxides and halides to this sulfide electrolyte, which greatly improves the chemical stability while ensuring the conductivity, greatly improving the life of this sulfide electrolyte and avoiding the risk of chemical reactions with other substances.

Simply put, the safety hazard of this sulfide electrolyte is eliminated.

In addition, the several auxiliary materials he added are relatively common industrial materials, and it is not difficult to obtain them, but the ratio and reaction process are a little complicated.

And this does not lead to increased costs.

In other words, this material perfectly solves the third major difficulty in the mass production of solid-state batteries, and also solves the second major difficulty in half.

Next, the only difficulty is to find the most suitable positive and negative electrode materials to match this new sulfide solid electrolyte.

After Su Xin rested for a while, he suddenly took a deep breath and said silently in his heart:
"Extreme speed, ten thousand times!"

In an instant, the world was silent, and everything seemed to be frozen.

Under such extreme acceleration, Su Xin's brain was extremely active, and his thinking was running wildly.

In his mind, various materials seemed to be reduced to the most basic molecules, even atoms, which allowed him to instantly understand the chemical nature of various materials. Based on these understandings, he combined and deduced according to the characteristics of various materials.

What kind of new properties are most likely to be produced by combining which kinds of materials through a series of chemical reactions or physical combinations?Best for matching with current sulfide electrolytes?

30 seconds later.

Su Xin released the super speed ability, and took a few breaths like a drowning person.

In the past few days, from time to time, he will use the super wisdom in the state of extreme speed to think, and conduct experiments based on the results of thinking again and again, so that he has such an exaggerated research and development efficiency.

Other top research teams in the outside world, let alone five days, even three to five years, can be considered very powerful if they can develop suitable solid electrolyte materials.

As for Su Xin, he just used dozens of extreme speeds, plus dozens of experiments.

According to the result of thinking just now, Su Xin began to try several positive and negative electrode materials one after another.

……

Two more days passed.

After dozens of experiments, Su Xin finally showed a relaxed smile on his face.

"Great, it's finally done!"

Just now, Suxin finally completed the test of the last new type of positive electrode material, and after many tests, this material has a high degree of matching with the sulfide electrolyte, and its stability is also extremely strong. It is resistant to high temperature and impact. This is also the most suitable material ratio.

The completion of this experiment also means that Suxin has broken through all the technical difficulties of solid-state batteries!
A solid-state battery with high temperature resistance, low temperature resistance, high energy density, high charging efficiency, and no safety hazards was born in his hands!
Next, as long as the appropriate production process is designed according to the experimental product, the adjustment of the production line is completed, and a suitable supply chain is found, mass production can officially begin!
After recording all the experimental data in the Tianwei database, Su Xin just sat down and drank a glass of water when he heard the reminder from Tiantian's assistant——

"Master, Liu Qingli is calling!"

Su Xin walked over and connected: "Qing Li, what's the matter?"

"Boss, several groups of people have come to the company to look for you. I have been pushing for several days, but you have not come back, so I can only disturb you."

Su Xin frowned: "Who?"

He knew that even if ordinary people went to the company to look for him, Liu Qingli would either simply refuse, or just ask someone to record it, or pass it on to his secretary Feng Haifeng, and would not disturb him easily.

Therefore, the identity of the visitor should be unusual.

On the other side of the phone, Liu Qingli said helplessly: "Those people are the admissions teachers of various colleges and universities. They said that you were not at your home, and they couldn't get through to you, so they all found a company. They offered very generous conditions and wanted to invite you to study."

"I really don't want to make decisions about this kind of thing. I can only ask them to wait for you to come back. As a result, they come to the company every day..."

"Didn't I say that I want to go to Beijing University? Why do they still come to me?"

Su Xin shook his head and refused decisively:

"You tell them that I don't need any conditions. I said I will go to Peking University, and I will only go to Peking University. The company is set up, and the house is bought nearby. How can I go to another school? Just help me refuse!"

"Okay, then I'll reply to them according to your words." Liu Qingli responded, and then asked again: "By the way, how is the research progress of new energy batteries? I heard from Director Li that you have completely stopped the research institute these days, and immerse yourself in researching new materials?"

"I've almost done my research. I just want to find you. I will contact a patent agency company to help me apply for several international patents for new energy power battery technology. I will arrange the production process here and go back."

Su Xin said lightly.

On the other side, Liu Qingli, who heard his words, froze in place, thinking that she had an auditory hallucination, and repeated in disbelief:
"You mean, you have already developed solid-state battery technology?!"
