   Chapter 487 Lithium-air battery?

  Currently 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.

  Compared with lithium-ion batteries, lithium-air batteries have a higher energy density because their cathodes (mainly porous carbon) are light, and oxygen is obtained from the environment instead of being stored in the battery.

  It sounds better than common lithium-ion batteries, but the development of lithium-air batteries is still in the initial 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 is now in front of the poster, watching the title and reading it again, only this time it has attracted 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 looked at the other party, wearing a polo shirt and jeans, in a typical engineering man's outfit.

  Her beard, dark circles around the eyes, looking like thirty or forty.

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

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

"me?"

  Chen Hao's mouth turned up, "I am studying polymer materials."

  "Polymer materials are also quite good." The man replied, but noticed that the other party was reading the paper seriously, so he didn't say anything.

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

  It was still in 2012 when the lithium-air battery field first published a paper in Nature and Science, which represented that 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 I look back, the contempt in Chen Hao's eyes gradually recedes.

  The expression in his eyes became serious.

"interesting."

  This paper unexpectedly surprised him.

  Twenty minutes later.

  Chen Hao roughly scanned the full text, and before he said he wanted 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 reports, it does not mean that the ability is not good.

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

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

  It's just that there are some surprises and confusion in his eyes.

  He turned his head to look at the other person, and asked, “Although there is no detailed preparation process in the paper, I guess you have tried some, right? Why didn’t you continue?”

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

   "Why disbanded? As long as there is a glimmer of hope of success, I think it is worth persevering." Chen Hao was confused. Is this company a fool?

  This is a lithium-air battery!

  Even if there is only a 10% probability of success, it is worth keeping on!

  Receipt is directly proportional to risk.

  The risk of lithium-air batteries is great, and the receipts after success are also huge!

  Like today's mobile phones, it changes almost every year, from the camera to the processor, basically there are enhancements.

  The only difference is that there is no change in the power supply, which 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 technology can solve many difficulties, but only energy will be locked.

  New materials are the forerunners of social change, but new energy is the milestone in promoting everything.

  The man shook his head, cursed and sighed and explained: “Because that company believes that all-solid-state lithium batteries are commercially available earlier than lithium-air batteries, they sponsored an all-solid-state lithium battery research team.”

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

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

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

  Chen Hao glanced at him sympathetically.

  What is the ideal carrier for next-generation batteries?

  It is not a lithium-sulfur battery, a sodium-sulfur battery, nor a **** graphene battery. Graphene batteries are used to bluff people and brush papers.

  All-solid-state lithium battery is a kind of lithium battery that uses solid electrodes and solid electrolyte.

  Solid-state batteries generally have lower power density and higher energy density. Because of the relatively high power and weight of solid-state batteries, it is an ideal battery for electric vehicles. In addition to its safety superior to traditional lithium batteries, all-solid-state lithium batteries have a great advantage, that is, the charging and discharging cycle life is very long, up to 45,000 times, and 95% of the initial capacity is preserved. This allows other The types of batteries are beyond the reach.

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

  Volkswagen has announced plans to develop solid-state batteries with a battery life of 1000km;

  Toyota Motor expects to complete the research and development of solid-state batteries in 2022, and plans to achieve mass production in 2030;

  BMW has reached a strategic cooperation with SolidPower, a solid-state battery manufacturer in China, to accelerate the research and development of solid-state batteries;

  Hyundai announced its investment in IonicMaterials, a Massachusetts-based company, 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 the performance of the vehicle. It is not difficult to see that solid-state batteries have become a new battlefield in the new energy vehicle industry.

  Similar to "charging for 1 minute, endurance of 800 kilometers", it is completely possible with all solid-state lithium batteries.

  In the industry, it is predicted that around 2025, the large-scale commercialization of all-solid-state batteries may arrive.

  Is the lithium-air battery better than the all-solid-state battery?

  Answer: Good!

   However, all solid-state batteries can see hope right now, but the optimistic estimate of lithium-air batteries will take 10 years before mass production is possible.

  Enterprises can wait 3 years, wait 5 years, but wait 10 years...some of them went bankrupt before they even survived.

  Plus the lithium-air battery is a continuous and costly investment, so it is quite understandable that the other party cancels the sponsorship.

   "What is your name?" Chen Hao asked.

"I?"

  The man froze for a moment, touched his nose, and introduced himself: "My name is Kenan Buniel and I am a professor at Penn State University Parker."

  "Oh, yes, I have taught myself some Chinese, you can also call me Zhou...yu." At the last two words, Buniel said Chinese with a little difficulty.

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

  Add the information in the system interface that pops up, and a new interface will pop up after a while.

  【Scientific research project: Li-air battery】

  [R&D personnel composition: Pennsylvania State University Parker-Professor Buniel]

  【R&D success rate: 15%】

  A single person has a 15% success rate? ? ?

  If this is a complete star scientific research team, wouldn’t it be the case that UU Read www.uukahnshu.com...

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

  He stretched out a hand calmly.

  "Hello Professor Buniel, I am Chen Hao, the president of Guanghua University. I am glad to meet you!"

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

  Ps: Ask for recommendation tickets and monthly tickets.

  There are so many materials on lithium-air batteries, which is dazzling. Simply put, finding a technology is an important help to solve energy, but the technology is difficult. According to the replacement, it should be solved in 5 years for all solid-state lithium batteries, and then 10-15 years for lithium-air batteries.

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