Black Technology: Start with Ten Thousand Times Speed

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 solid-state batteries that are mature and mass-produced can be developed, it will completely subvert the automotive industry, making existing new energy vehicles completely uncompetitive, and making traditional fuel vehicles unable to withstand them.

Those who master this technology will become the overlord of the global energy industry. They can also use this technology to radiate multiple industries and influence multiple industrial chains, thereby affecting the global structure and possessing 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 changes in the production process, the entire production line has to be redesigned and adjusted, employees need to be retrained, production specifications need to be re-formulated, and product quality control also needs to be skilled.

These will inevitably lead to a significant increase in production costs, making the originally advantageous solid-state batteries lose their competitiveness.

Second, the electrolytes and positive and negative electrode materials used in solid-state batteries are relatively new materials. The supply chain system is not yet complete, and large-scale mass production has not yet been formed. Some materials even 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, thereby leading to a loss of competitiveness.

Third, fast charging efficiency is poor.

The conductive efficiency of solid electrolytes is only about one-tenth that of liquid electrolytes, which can be simply understood to mean that the charging efficiency is only one-tenth that of current new energy vehicles.

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

The most critical second and third difficulties.

These two major difficulties are actually ultimately a matter of materials.

The best way to solve this problem is to develop a material with good conductivity, sufficient stability and safety, and not too difficult to obtain.

Su Xin's research these days is to test the material ratios of various solid electrolytes.

And today, he finally had a breakthrough!

After testing, the conductivity of a sulfide solid electrolyte he just developed reached 1.2x10-2S/cm, which is already equivalent to the conductivity of liquid electrolyte. Coupled with the high energy density of solid-state batteries, it can fully meet the needs of Daily use needs of new energy vehicles.

The most important thing is that the sulfide solid electrolyte originally envisioned by scientists has huge shortcomings of poor electrochemical stability and poor air stability, which will lead to insufficient battery life. It may also react with water or air to produce toxic substances and pose safety risks. larger.

This is also the biggest problem that many companies are currently facing.

Now, Su Xin has added several metal oxides and halides to this sulfide electrolyte, which not only ensures the conductivity, but also greatly improves the chemical stability, greatly extending the life of this sulfide electrolyte and avoiding the need for 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 they are not difficult to obtain, but the proportions and reaction processes are a little complicated.

And this will not result in increased costs.

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

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:

Super 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 thoughts were running wildly.

In his mind, various materials seemed to be reduced to the most basic molecules, or even atoms, allowing him to instantly understand the chemical nature of various materials. Based on this understanding, he performed combination deductions based on the characteristics of various materials.

Which kinds of materials are combined, and through a series of chemical reactions or physical combinations, what new properties are most likely to be produced? Best matched to current sulfide electrolytes?

Thirty seconds later.

Su Xin released his divine speed ability and took a few big breaths like a drowning person.

In the past few days, he would use his super intelligence at extreme speed to think from time to time, and conduct experiments based on the results of his thinking again and again, so that he could have such exaggerated research and development efficiency.

If you compare it to other top research teams in the outside world, it would be considered very impressive to be able to develop a suitable solid-state electrolyte material in three to five years, let alone five days.

As for Su Xin, he just used his extreme speed dozens of times, plus dozens of experiments.

According to the results of his 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.

Great, it's finally done!

Just now, Su Xin finally completed the test of the last new cathode material. After many tests, this material has a high degree of matching with the sulfide electrolyte, is extremely stable, and is both high temperature and impact resistant. , which is also the most suitable material ratio.

The completion of this experiment also means that Su Xin has overcome all technical difficulties of solid-state batteries!

A solid-state battery with high temperature and low temperature resistance, high energy density, high charging efficiency, and no safety hazards was born in his hands!

Next, as long as we design a suitable production process based on the experimental finished product, complete the adjustment of the production line, and find a suitable supply chain, we can officially start mass production!

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 Assistant——

Master, Liu Qingli called!

Su Xin walked over and answered the call: Qingli, what's wrong?

Boss, several groups of people have come to the company to look for you. I've been pushing them for several days, but you haven't come back, so I can only disturb you.

Su Xin frowned: Who is it?

He knew that even if most people went to the company to find him, Liu Qingli would either refuse outright, or just have someone record it, or tell his secretary Feng Haifeng that he would not be disturbed easily.

Therefore, the identity of the visitor should be unusual.

On the other side of the phone, Liu Qingli said with some helplessness: Those people are admissions teachers from major universities. They said they would go to your home but you were not there, and they couldn't get through when they called you, so they all came to the company and they issued an application. The conditions are very favorable and I would like 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 tell you that I wanted to go to Beijing University? Why are they still looking for me?

Su Xin shook his head and decisively refused:

You tell them, no matter what conditions are offered, I don't need it. I said I would go to Beijing University, so I will only go to Beijing University. I have set up a company and bought a house nearby. How can I go to another school? Just help me. Say no!

Okay, then I will reply to them according to your words. Liu Qingli responded, then asked: By the way, how is the research progress of new energy batteries? I heard Director Li report that these days God, you stopped the research institute completely, and you are alone in it to research new materials?

I've almost finished my research. I'm going to contact you later. I'll contact a patent agency to help me apply for several international patents on new energy power battery technology. I'll arrange the production process here and then 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?!
