"Of course nuclear fusion is better for batteries, but we don't have that technology."
"The current Ternary Lithium Battery, Lithium Iron Phosphate Battery, etc. are all ternary materials and conventional structure batteries under the existing theoretical system. They all work hard on the structure to increase the energy density as much as possible. However, no matter how they are designed, they cannot exceed the theoretical value of 350wh/kg."
"If you want to exceed this theoretical value and achieve energy density of 400/500 or even higher, single-element lithium-sulfur batteries are also a good choice. The theoretical specific capacity of sulfur can allow the design theory of lithium-sulfur batteries to reach 2600wh/kg, which is about seven times that of ternary batteries. Moreover, sulfur is cheap and abundant on this planet. The price is only 1,000 degrees per ton, which is more than a hundred times lower than the high price of those ternary materials, which can easily cost hundreds of thousands per meal.
However, since Galaxy Technology Library does not include lithium-sulfur battery technology, only Lithium-Air Battery, obviously Lithium-Air Battery is better.
Also, one sulfur needs to be mined. Lithium-Air Battery directly uses air as a pole, which saves money. Moreover, more lithium can be released on the other pole, and the theoretical energy density that can be achieved is higher, which can reach an energy density of 5,000 degrees to more than 10,000, which is a breakthrough..."
After disassembling the battery and getting familiar with it carefully for a period of time, Zhou Feiyu began to work on the second technology, which is "Lithium-Air Battery Technology".
This is an old technology that has been talked about for decades, but has never been realized.
The closest one is a technical solution jointly developed by Professor Wang Gang from Zhendan University in Shanghai and a research institute called Little Country. However, it only solves some of the difficulties in Lithium-Air Battery. There are other bigger difficulties that have not yet been solved, so it is still said that "it will take ten years to be commercialized."
Well, just like Controlled Nuclear Fusion, it is said year after year that there are still many years left for commercial use.
After understanding all the knowledge about "Lithium-Air Battery Technology", Zhou Feiyu knew that the technical solution proposed by Professor Wang Gang is actually very feasible. However, in order to truly follow this technical solution to realize the commercial use of Lithium-Air Battery, the key lies in how to choose oxygen in the air and solve the problem of solid electrolyte membrane.
The use of oxygen as the positive electrode is purely theoretical. In fact, the battery is used in real conditions. At this time, it faces a problem, that is, in addition to oxygen, there are many other gases in the air, as well as too many impurities, water vapor, and so on.
The lithium in Lithium Battery is a metal with very active chemical properties. In addition to chemical reactions with oxygen, it also reacts with other impurity gases. This will lead to the production of many impurities and the corrosion of the lithium itself. Ultimately, the battery life is too short, the energy density is too low, and various risks during use.
Therefore, the oxygen in the air must be purified and used, and only oxygen can pass into the battery. This has high requirements for materials, which require high performance, ultra-thinness and low cost.
In addition to this, the channels between the lithium and the electrolyte inside the battery are also difficult to deal with. Lithium ions need to react, but they cannot react in a channel. The characteristics of the channel itself are extremely demanding, which results in either high cost and low performance, or considerable performance but another fatal flaw.
There are no comprehensive options to choose from, so we can only despair.
Solid Electrolyte Thin Film As a channel, polymer ceramic material is often chosen, but it easily becomes extremely fragile during the battery discharge and charging process and breaks when touched. This has not been solved yet.
"Porous Carbon is not enough. We have to find a way to use other more advanced carbon composite materials. The same is true for solid electrolyte membranes. In this case, Intermediate Thin Film Technology will be used."
Zhou Feiyu's mind was racing, and he made some simulation calculations in his mind, and a set of feasible verification plans naturally emerged in his mind.
Here, Intermediate Thin Film Technology, which he had played tricks on before, can come in handy.
Thanks to the complete set of solutions of "Lithium-Air Battery Technology", Zhou Feiyu is now just restored using the knowledge gained. And with the foreshadowing of the previous technology, the speed this time is still very fast.
With one order, many materials were purchased, even some that were difficult to buy on the market, and were delivered to Zhou Feiyu within two days.
On the third day, by the end of September, the finished Lithium-Air Battery prototype was produced. It was only as big as a fist. Installing it on Zero Zero One Robot was like having a strong heart.
After restarting, Zero Zero One Robot's power display shows that the available supply time has increased from the original ten uninterrupted hours to one hundred and twenty uninterrupted hours, a full twelve times increase.
"Yes, yes, this power can be said to be surging power."
Zhou Feiyu is very satisfied, this battery has reached its design value.
Although this power does not reach the highest theoretical value of Lithium-Air Battery and is still far behind, the twelve-fold improvement can still be said to be a qualitative breakthrough compared to today's most advanced ternary material batteries!
This battery size matches the Zero Zero One Robot, and is not necessarily this size.
This Lithium-Air Battery can also be matched with end products such as cars, mobile phones, laptops, home appliances, toys, etc., and the design can be adjusted according to different structures.
Of course, different structures naturally have different electrical capacities. The larger the volume, the greater the mass of metallic lithium and the higher the electrical capacity. This is self-evident.
Therefore, big means high.
"What good materials is the boss working on recently?"
"It must be related to thin film materials. All our experimental data on thin film materials have been transferred in the past two days."
"You said, the boss won't really make a robot, right?"
"If you really do it, it will be awesome."
"Yes, from now on our Feiyang will be as awesome as Tesla. No, it should be said that we will be a terminal company even more awesome than Tesla."
While Zhou Feiyu spent a few days quietly overcoming world-class problems, there was also some discussion about the Research and Development Department door inside the Feiyang factory.
The Research and Development Department door aims to expand derivative work on materials that have been developed, and it has been very fruitful recently.
Whether it is optical materials or PI Material, Holographic Material, a variety of derivative models have been successfully developed and introduced into mass production, greatly expanding Feiyang's product line.
In particular, various derivatives with PI Material as the core have dozens of subdivided materials with high and low temperature resistance, radiation resistance, flexibility, low resistance, high resistance, permeability, insulation and conductivity, etc.
The material data accumulated by the Research and Development Department, including performance data, experimental data, useful or useless data, is even more vast.
Zhou Feiyu transferred all these data. It obviously has a purpose. The most reasonable guess is that he is developing a new breakthrough material with significant effects.
With the current competition with Tesla's telephony, it would be impossible for them not to test this aspect.
"When will Tesla's press conference start?"
"It seems like it's tomorrow, October 1st."
"Damn, you're doing this on National Day? You did it on purpose."
"It's definitely intentional, but it's not tomorrow, it's today. The time difference between them and ours is different. They were at eight or nine in the morning on the 1st, and ours was around nine or ten tonight."
"Can we all watch together tonight?"
"You must read it. Know yourself and know your enemy."
Research and Development Department men and girls all agreed with this proposal.
It can be said that the release of Tesla and Humanoid Robot is highly anticipated. No matter what your mood is, you have to watch it first before talking about it.
But what no one who posted Research and Development Department expected was that at seven o'clock in the evening, Fei Yang Information suddenly sent Weibo again.
Weibo There is only one video, but everyone who saw it was shocked...
