If the gas molecular screening problem cannot be solved, the lithium-air battery produced must be backed with an oxygen tank behind it. There is no need to think about the mobile phone. New energy vehicles are not sure.

However, no one should be willing to have their own car, and every time they ignite, they have to risk turning into a rocket and flying into the sky.

Jiang Qiye studied all the information in front of him bit by bit.

The positive electrode is a gas chamber covered by a gas screening membrane, and the negative electrode is a lithium negative electrode material wrapped in electrolyte...

Energy conversion coating, fluorescent coating...

In addition to the electrolyte solution that is an ordinary sulfur lithium battery electrolyte, several other things have great research value.

The design structure of the crystal is simple and clear, and it is clear that even if it is placed in front of the earthlings and copied, no one can copy it.

Because the technical difficulties are all in the details, many problems that originally needed to be solved from the perspective of design are all solved in the materials.

Jiang Qiye tried to check the molecular formulas of those materials online, but he could not find any information about these formulas at all. These things are a brand new material that has never appeared before.

Looking at the vast data, Jiang Qiye decided to study it first, and use his current resources to replicate the gas screening diaphragm on the positive electrode material.

The molecular formula of this diaphragm is polydimethylsiloxane. This material is not uncommon and can even be found in some skin care products and shampoos.

The nanopore structure in this gas screening film is one of the keys to solving lithium ion transport and gas screening.

As for nanopore films made of polydimethylsiloxane, Jiang Qiye thinks that they can be prepared by spin coating and hydrofluoric acid etching, or they can be prepared using LIGA and lithography systems in the laboratory.

Although it may not be able to completely restore the technology to crystals at present, it is still possible to imitate this as a template.

With the resources currently on Jiang Qiye, you can be sure to make this gas screening film.

After saving all the data, Jiang Qiye just withdrew from the Science City.

I looked at my phone and it was already twelve o'clock in the morning.

Sleepiness came instantly, and he closed his eyes and fell asleep immediately.

The next day, Jiang Qiye got up early and rushed to the laboratory after class.

He did not plan to conduct experiments in the junior laboratory, first of all, because he has few points now, so there is no need to spend a portion of this kind of small experiment.

Secondly, Zhao Zhengguo's laboratory has the conditions to conduct experiments. As the second person in charge of the laboratory, if he can make results in the laboratory, it will be of great help to future scientific research funding applications.

In addition, the selection of young scholars is about to be conducted, and a heavyweight achievement is also of great help in the selection.

Moreover, once this gas screening film is made, it will definitely make battery manufacturers around the world crazy, because once the gas screening problem is solved, it means that the sulfur lithium battery can be upgraded to a sulfur lithium air battery, which can greatly improve both its safety issues and energy storage effects.

I must apply for a patent myself.

Once he has to apply for a patent, it means that he must make this thing at least once in a real laboratory.

Otherwise, many things cannot be explained, not to mention that applying for patents and writing papers also requires experimental data as support.

In fact, if you have time, Jiang Qiye can even figure out the production process and register a set of patents for the supporting industrial production process, and eat the profits of the sulfur and lithium batteries cleanly. Even if you don’t produce them yourself and sell them to others at a reasonable price, there is no problem at all.

However, Jiang Qiye did not choose to do this.

First of all, the technology in design and production is really beyond his ability.

Another thing is that he has a clear positioning of himself. As a scientific research work, not a specialist or businessman.

If you really monopolize all your technology, and not talk about whether you will offend people, the time will be incalculable.

If you have that time, it is better to use the patent fee to upgrade the equipment and reverse the technology from this crystal.

It is neither necessary nor efficient to conduct research and run factories.

After all, doing research and making products are two different things, but many people habitually confuse them. To make the best of what they are good at is much more efficient than to make one hammer and one stick.

He was in the laboratory at this time, proficiently operating the experimental instruments.

In fact, as early as 20 years ago, lithium metal was abandoned by the industry as a negative electrode. Because lithium is too active, it can react with almost all the gases in the air, causing various short-circuit problems, turning the battery into a burning/incident bomb, and even "exploded" a listed company with a market value of 10 billion yuan.

There is IBM at the enterprise level, and even prepared a supercomputer for the lithium air battery project, allocating the path of each gas molecule into the battery cell to avoid gas blockage... Although it was later discovered that it was a bottomless pit and was cut off by capitalists without mercy.

However, because of the strong market prospects of lithium metal, it still attracts countless materials science laboratories in the world to pour in on this topic.

Japan is currently the farthest in the world. They are currently studying how to pass the gas through nanocarbon films, but there is no good news at present.

As for why lithium batteries have such fascinating magic, we have to mention the concept of energy density.

The so-called energy density is the energy contained in a unit volume. As the most important indicator to measure the performance of a battery, improving energy density has always been the pursuit of the industry.

Even in the 13th Five-Year Plan of China, a clear plan was made that the power battery technology level should be synchronized with the international level by 2020 and the production capacity scale should remain globally leading. The most core red line is to increase the energy density of power batteries to 300-350Wh/kg.

At present, the lithium-sulfur air battery that Jiang Qiye is studying in the laboratory is the most likely to be the first.

Once the gas filtration problem can be completely solved, all the hot concepts currently being hyped in the academic community must give way to sulfur and lithium air batteries.

Anyone who has studied chemistry knows that first of all, the lithium metal negative electrode has the lowest electrochemical potential -3.04V, not to mention a specific capacity of up to 3861mAh/g.
