Chapter 487 Lithium-air battery?
At present, commercial batteries are mainly lead-acid batteries and lithium batteries, and lithium batteries are currently roughly divided into four categories: lithium-ion batteries, lithium-sulfur batteries, lithium-air batteries and lithium-oxygen batteries.

As for the lithium-air battery, it is a battery that uses lithium as the negative electrode and oxygen in the air as the positive electrode reactant.

Li-air batteries have a higher energy density than Li-ion batteries because their cathodes (based on porous carbon) are light, and oxygen is captured from the environment rather than stored in the battery.

It sounds better than common lithium-ion batteries, but the development of lithium-air batteries is still in the early research stage, and there are still many unsolvable technical difficulties before practical application and commercialization.

"Study on the preparation and performance of key materials for lithium-air batteries."

Chen Hao stood in front of the poster, looked at the title and read it again, but this time it caught the attention of the stall owner.

"Hey, mam, are you interested in lithium-air batteries?" The other party stood up excitedly and asked Chen Hao.

Chen Hao took a look at the other party. He was wearing a Polo shirt and jeans, which was a typical engineering man's attire.

Beard, some blackness around the eye circles, looks about [-] to [-] years old.

"A little interested." Chen Hao nodded slightly, his eyes continued to fall on the other party's paper.

"What direction are you researching?" The other party didn't seem to recognize Chen Hao, but asked curiously,
"me?"

The corner of Chen Hao's mouth curled up, "I study polymer materials."

"The polymer material is also quite good." The man responded, but noticed that the other party was reading the paper seriously, so he didn't say anything.

At first, Chen Hao was a little contemptuous. After all, the technology of lithium-air batteries is far from mature.

It was only in 2012 that the lithium-air battery field published a paper in Nature and Science for the first time, which represented that the lithium-ion-air battery was officially recognized by the world's top journals.

Prior to this, lithium-air batteries were not recognized by the scientific community.

It's just that the more he looked back, the contempt in Chen Hao's eyes gradually disappeared.

His eyes became serious.

"interesting."

This paper surprised him a bit.

Two 10 minutes later.

Chen Hao roughly scanned the full text, and before he could ask for it, the man beside him couldn't wait to ask:

"how is it going?"

Although the poster posting area is a place for guests who have not received oral presentations, it does not mean that all abilities are not enough.

There will also be some big cows who like to communicate with people in this way. Of course, it is also possible to find some high-quality articles in the Poster posting area just like Taobao.

"The paper is good overall, with some novel ideas. It is a good paper." Chen Hao took the lead in affirming it. Naturally, it is not difficult to read this paper with his strength.

It's just that there was some surprise and confusion in his eyes.

He turned his head to look at the other party and asked, "Although there is no detailed preparation process in the paper, I guess you should have tried something, right? Why didn't you continue?"

"Because the sponsor stopped sponsoring, the lithium-air battery research group also disbanded." The man said bitterly.

"Why disband? As long as there is a glimmer of hope for success, I think it's worth persevering." Chen Hao was confused. Is this company an idiot?

This is a lithium-air battery!
Even if there is only a 10% probability of success, it is worth sticking to!

Receipt is directly proportional to risk.

The risk of lithium-air batteries is high, and the receipt of goods after success is also huge!
Like the current mobile phone, it changes almost every year, and everything from the camera to the processor is basically enhanced.

But the only thing is that there is no change in the power supply, it is still a five or six thousand mAh battery, and at most it is a fast charging technology.

why?
Because the limit of chemical power is there, human science and technology can solve many difficulties, but they will only be locked by energy.

New materials are the forerunner of social change, but new energy is the milestone that drives everything.

The man shook his head, cursing and sighing and explained: "Because that company believes that all-solid-state lithium batteries are commercially available earlier than lithium-air batteries, so they sponsored a research team for all-solid-state lithium batteries."

"Damn all solid-state lithium battery! Falk!"

"The new energy of the future belongs to lithium-air batteries!"

After venting a few words in succession, the man was like a deflated balloon, and his whole body was sluggish.

Chen Hao glanced at him sympathetically.

What is the ideal carrier for next-generation batteries?
It's not a lithium-sulfur battery, a sodium-sulfur battery, let alone a shitty graphene battery. Graphene batteries are just used to bluff people and write papers.

An all-solid lithium battery is a lithium battery that uses solid electrodes and a solid electrolyte.

Solid-state batteries generally have low power density and high energy density.Solid-state batteries are ideal batteries for electric vehicles due to their high power-to-weight ratio.In addition to superior safety compared with traditional lithium batteries, all-solid lithium batteries have a great advantage, that is, the charge and discharge cycle life is very long, up to 45000 times, and 95% of the initial capacity is preserved, which allows other The kind of battery is beyond compare.

Moreover, the progress of car companies in solid-state batteries is faster than that of battery companies.

Volkswagen has announced that it plans to develop solid-state batteries with a battery life of 1000km;
Toyota expects to complete the research and development of solid-state batteries in 2022, and plans to achieve mass production in 2030;
BMW reached a strategic cooperation with Solid Power, a solid-state battery manufacturer, to accelerate the research and development of solid-state batteries;

Hyundai announced that it invested in IonicMaterials, a company located in Massachusetts, which is mainly engaged in the research and development of solid-state batteries...

As the core of new energy vehicles, power batteries play a decisive role in vehicle performance. It is not difficult to see that solid-state batteries have become a new battlefield for the new energy vehicle industry.

Something like "charging for 1 minute, and a battery life of 800 kilometers" is completely possible on an all-solid-state lithium battery.

The industry predicts that around 2025, the large-scale commercialization of all-solid-state batteries may come.

Are lithium-air batteries better than all-solid-state batteries?
Answer: Yes!
However, all-solid-state batteries can see hope right now, but it is optimistic that lithium-air batteries will be mass-produced after 10 years.

Enterprises can wait for 3 years or 5 years, but wait for 10 years... Some companies go bankrupt before that time.

In addition, lithium-air batteries are a continuous and costly investment, so it is very understandable for the other party to cancel the sponsorship.

"What's your name?" Chen Hao asked.

"I?"

The man froze for a moment, touched his nose, and introduced himself: "My name is Kenan Bunier, and I'm a professor at Pennsylvania State University, College Park."

"Oh, by the way, I have learned some Chinese by myself. You can also call me Zhou... Yu." When it came to the last two words, Bunier pronounced the Chinese with a little difficulty.

"System, use academic eyes." Chen Hao said silently in his heart.

After adding the information in the pop-up system interface, a new interface pops up after a while.

【Scientific Research Project: Li-air Battery】

[Composition of R&D personnel: Pennsylvania State University, College Park-Professor Bunier]

【R&D success rate: 15%】

Just one person has a 15% success rate? ? ?

If this is a complete star scientific research team, wouldn't it be...

Chen Hao's eyes and pupils shrank, and he forcibly suppressed the joy in his heart.

With a calm face, he stretched out a hand.

"Hello, Professor Bunier, I'm Chen Hao, the president of Guanghua University, nice to meet you!"

"As for the sponsorship of lithium-air batteries, I think we can find a coffee shop to sit down and talk, what do you think?"

ps: Ask for a recommendation ticket, ask for a monthly ticket.

There are so many materials about lithium-air batteries, it’s overwhelming.To put it simply, finding a technology is an important help to solve the energy problem, but the technology is very difficult. According to the replacement, it should solve the problem of all-solid lithium batteries within 5 years, and then solve the problem of lithium-air batteries in 10-15 years.

Because the all-solid-state battery is almost completed, in order to overtake, a lithium-air battery is arranged for the protagonist.
