Speaking of this, Pang Wei said quite nostalgically: "I still remember that one time, when I happened to take an elevator with Mr. Yang, Mr. Yang asked me which unit I was from, and I said the one from the University of Science and Technology."

"Then Mr. Yang said, 'There is a guy named Pang Wei in your school who is doing a good job.' I started laughing at that time."

"Oh? This kind of thing has happened before." Lin Xiao couldn't help but laugh.

"Yeah." Pang Wei smiled and said, "Okay, I won't say much more. It will probably take some time to build our new quantum computer, about a month. I will contact you then."

"good."

Lin Xiao replied and then hung up the phone.

In the next month, Lin Xiao continued to optimize his model. At the same time, he did not forget to research on lithium-sulfur batteries.

Regarding the research on solid electrolytes for lithium-sulfur batteries, the progress is slower than that of proton batteries, and this has a certain relationship with the difficulty of research on solid electrolytes. Of course, it is also due to the fact that Lin Xiao has made most of the research about solid electrolytes during this period.

My thoughts were focused on the qubit control model and the strange one-way function.

Now, he finally has time to focus more on lithium-sulfur batteries.

That's it, about half a month later.

"nailed it!"

In the laboratory.

They looked at the battery reaction pool that had been set up.

There is a solid object in the middle, and this solid object is naturally a solid electrolyte. This is a modified lithium iodide. It is doped with some other special substances to give it the characteristics of a solid electrolyte, or fast ions.

Characteristics of conductors.

That is to say, it has ionic conductivity and low ionic conductivity activation energy comparable to liquid electrolytes.

The biggest problem with solid electrolytes is whether the flow of ions inside them can be as smooth as in the electrolyte. Once this problem is solved, it will have the ability to become a solid electrolyte. Then it will need to solve some of the shortcomings of a compound.

That’s it.

Of course, in addition to this solid, there are two solid rods next to it, one of which is the metallic lithium rod. Of course, the metallic lithium rod must not be in direct contact with the air, because the moisture contained in the air comes into contact with the metallic lithium.

A more violent reaction may occur, causing danger.

In addition to metallic lithium, there are sulfur carbon rods.

Since the sulfur element will have a certain impact on the battery during the reaction process of the lithium-sulfur battery, Lin Xiao specially developed such a sulfur carbon rod to avoid the impact of sulfur element in the reaction.

In this way, all the shortcomings of lithium-sulfur batteries have been solved.

"Then, it's time to witness the miracle!"

Kang Chengning and others had excitement on their faces, and then they started the experiment.

The external circuit is connected, the reaction begins, and the current and voltage are quickly detected on the meter.

Of course, this is not over yet. Next, they need to observe the discharge process for several hours and test various data.

Just like that, as time passed, a few hours later.

"It's been detected! The energy density is 2200 watt hours per kilogram!" Ma Bin shouted excitedly.

“2200 watt hours? Beautiful!”

Others also became happy.

Although the theoretical energy density of lithium-sulfur batteries is 2600 watt-hours per kilogram, it is also said to be a theoretical energy density after all.

Just like in the development of lithium-ion batteries, the energy density can be continuously improved because it has not yet reached the theoretical energy density. In this process, various battery components, binders and other substances will affect

to its actual energy density.

So the data they calculated now is 2200 watt hours per kilogram. Of course, if it is further made into a commercial battery, the loss will be even more. In the end, half of 2600 watt hours per kilogram is considered good.

Already.

"However, as long as it can be maintained above 1,000 watt-hours per kilogram."

Lin Xiao on the side also showed a satisfied smile.

Compared with proton batteries, lithium-sulfur batteries obviously have lower energy. However, the key problem is that proton batteries require colloidal electrolytes, proton exchange membranes, and new hydrogen storage materials. The cost is inherently high, so they are relatively more suitable for use.

On electric vehicles and some large facilities.

The cost of lithium-sulfur batteries is relatively low. Of course, the energy density is also relatively low. However, it can be used in mobile devices such as mobile phones, so the profits are not too small.

"Then, let's see what BYD and CATL will choose."
