After a pause, Wang Guanghe continued: "And more importantly, because of your existence, our country has been at the forefront of the world in the field of lithium batteries for the first time."

"So we hope to hear your opinions and opinions on the future development of lithium batteries."

"Including how to research lithium batteries in the future, whether it is lithium-sulfur batteries or lithium-air batteries, or other directions, etc."

At this point, Xu Chuan understood what they wanted to ask.

I just want to ask if there is any hope of surpassing those Western countries such as Britain and America in the field of lithium batteries.

Competition between countries is ubiquitous, especially in the frontier fields of science and technology, from lithography machines to aerospace, from bioscience to materials chemistry, etc. Each country has its own development.

Lithium batteries, which have never been fully mature, are something that Huami, East Asia and other countries around the world are studying.

Especially now that the lithium dendrite problem has been solved by him in advance, the development of lithium batteries has branched off into several different routes.

Lithium metal batteries, lithium-ion batteries, lithium-sulfur batteries, lithium-air batteries...etc., all have their own advantages and disadvantages.

If we just talk about this, he can still give some opinions.

Heaving a sigh of relief, Xu Chuan smiled and said, "If that's the case, I can say a few words."

Upon hearing this, Qin Anguo and Wang Guanghe immediately sat up straight and said in unison, "Say it."

Xu Chuan pondered for a moment and then said: "I probably know what you are thinking."

"The three key factors for the development of lithium-ion batteries are nothing more than three: high safety, high energy density, and low cost."

"This is the future development trend of lithium batteries. Whether it is lithium-sulfur batteries or lithium-air batteries, they need to be based on these three basic factors."

"I know you must have done your own research. Perhaps because of various issues such as patents, you are more inclined to lithium-air batteries in the current blank area. After all, there are many laboratories researching lithium-sulfur batteries, and our country started relatively late."

This chapter is not finished yet, please click on the next page to continue reading the exciting content! "But how to say, I actually recommend doing it step by step."

"It is undeniable that the energy density of lithium-air batteries is quite high, even comparable to that of petroleum, but there are too many problems that need to be solved."

"The lithium dendrite problem is just one of a kind."

"For example, the reaction kinetics of lithium-air batteries on the positive electrode is a problem because the discharge product of the positive electrode is solid li2o2 and other materials, which are insulating and will cause the positive electrode reaction kinetics to be slow. This leads to low energy density and short cycle life.

, a series of problems such as poor rate performance and low energy efficiency.”

"There are also intermediates formed during the electrochemical process, lithium superoxide and lithium peroxide, which will degrade the battery from the inside, greatly limiting the battery cycle life and other issues."

"These are quite difficult to solve."

Regarding these, Xu Chuan did not tell lies.

I have to admit that the energy density of lithium-air batteries is indeed very attractive. Its theoretical specific energy can reach 11.4kwh/kg, which is comparable to oil combustion.

In the face of attractive prospects, lithium-air batteries face far more problems than lithium-ion batteries and lithium-sulfur batteries.

But even before rebirth, lithium-air batteries still only existed in ppt files or in laboratories.

This isn't just a problem with lithium dendrites.

It is a series of complex oxidation reactions, including how to separate pure oxygen from the air at low cost, including the production of lithium oxide, which will reduce battery life, etc.

These are no less difficult problems than lithium dendrites, or even more difficult.

After writing down Xu Chuan's opinions with a pen, Qin Anguo raised his head and couldn't help but ask: "What if it was you who took action? Is there any hope of solving these problems?"
