Chapter 434: Gel Lithium Battery [Fourth update, please vote for me]

It's getting more intense, there are two more updates, please give me a try!

This Mr. Jin is really unfathomable, you can’t see through it, you can’t see through it, it’s okay, if he’s not in a hurry to leave now, then you can take him around and see if you can get something out of him?

If there is, then that's the best. If this guy comes out with a few random words, the impact on his laboratory will be revolutionary!

Binxinwei also calmed down at this time and was no longer in a hurry to do experiments. Instead, he calmly took Jin Xiaoqiang around and started walking around.

The first floor of the battery laboratory occupies a large area. The two rooms facing the sun are reserved for the positive and negative electrode research rooms of the battery, while the north-facing side is reserved for the electrolyte research room.

What people call lithium batteries now is actually very different from real lithium batteries. Today's lithium batteries should actually be called lithium-ion batteries. There is no lithium metal in the battery at all, and all lithium-containing materials are used.

Lithium compounds.

If we want to talk about pure lithium batteries, we have to go back to the Edison era. The ones invented by Edison are called pure lithium batteries. However, the old man used lithium metal as the negative electrode of the battery. However, because the chemical properties of lithium metal are too reactive,

It is very easy to catch fire or explode, so since then, lithium batteries have always existed in legends and have not been promoted and developed on a large scale because they are too dangerous.

It was not until recent years that mankind began to slowly enter the post-petroleum era. With the increasing depletion of petroleum energy, mankind began to constantly ponder and develop the next generation of alternative energy sources. In this way, the concept of lithium batteries was once again hyped.

Got up.

It's just that this time humans are much smarter. They learned from Edison's experience in developing lithium batteries and began reverse research and development. They no longer directly used lithium metal, but used lithium-containing compounds, and also used this material as the positive electrode, and in the negative electrode

On the other hand, graphite is used.

Through the principle of potential difference, charged lithium ions continuously shuttle between the positive electrode and the negative electrode, thus completing the charging and discharging work.

In other words, during the charging and discharging process, lithium ions still have to pass through some media.

At present, the research and development of lithium batteries is mainly concentrated in the field of small batteries. Everyone mainly hopes to use this kind of battery to improve the efficiency of batteries used in mobile phones or laptops.

As for the research and development of lithium batteries used in large hybrid vehicles, it is still in the exploratory stage, because until now, there are still many lithium battery R&D companies that have not figured out what kind of materials should be used as the positive and negative electrodes of lithium batteries.

.

In terms of the first generation of lithium batteries that will be launched next year, the positive and negative electrode materials of lithium batteries will be announced soon, which will also provide opportunities for many lithium battery manufacturers.

People have already made it clear what materials are most suitable as the positive and negative electrodes of lithium batteries. The only thing left is to work on the electrolyte.

After all, the electrolyte is a very important component that can affect the charging and discharging efficiency of the battery and the power it carries. It is an important tool that can directly affect the quality of a battery.

Now Jin Xiaoqiang wants to take a look at how far Binxinwei and the others have developed in terms of lithium ion conductive media for lithium batteries.

"This is our media R&D center. Currently, the purpose of lithium battery R&D in the world is mainly for batteries for mobile phones or laptops. However, our battery R&D center, since its establishment, has been mainly focused on providing lithium batteries for hybrid vehicles.

purpose, so the current world master

The direction of research and development is different from ours, but I have also done that part of theirs and have not left it behind, so it is also divided into two parts. One part is to develop batteries for mobile phones or laptops, and the other part is to develop batteries for mobile phones or laptops.

Part of it is developing media specifically for hybrid vehicles.”

Binxin pointed to the two large Chaoyin laboratories in the north of the corridor and introduced them to Jin Xiaoqiang.

Well, the direction is correct, but I don’t know where you are in the steps of research and development. Jin Xiaoqiang nodded, indicating that he heard Binxin WeChat’s introduction, while secretly thinking about it in his stomach.

"Mr. Jin, our media R&D department is divided into two departments. One department specializes in the research and development of conductive media for batteries required by hybrid vehicles. The research and development direction of this department is mainly to use electrolytes. And the other department

The research and development direction of one department is towards the research and development of solid and gel point-to-point media. Currently, all

It is in the initial stage. The main reason is also because the two levels of our battery have not been determined. However, your prompts today have given me a lot of inspiration. I can basically confirm the results of our battery research laboratory on lithium batteries.

The research and development direction of the cathode has been set, and I believe the remaining electrolyte part can be completed in a very short time.”

Binxin explained to Jin Xiaoqiang confidently on WeChat.

"Well, by the way, since the positive and negative electrodes could not be determined before, and the electrolyte required for large lithium batteries cannot be determined, then the solid conductive medium of small batteries should be determined, right?"

Jin Xiaoqiang asked casually, and Binxin WeChat next to him was speechless. This boss doesn't understand anything at all. Does he obviously understand everything?

It is true that the electrolyte of lithium batteries is actually divided into two types, one is liquid, and the other is solid and gel. The principle of liquid electrolyte is actually the same as that of storage batteries. It is mainly aimed at large battery packs, that is, used in hybrid electric vehicles.

The large battery on the car.

As for solid electrolyte, it is actually aimed at small-type lithium batteries used in mobile phones or laptops. In fact, the Japanese have been researching such batteries for some years, and have even begun to promote them on a small scale. However, because of the positive electrode

The material has been under development and improvement in recent years, so this kind of battery has not yet been marketed on a large scale.

But the solid electrolyte of this small battery is actually no secret!

The meaning of Jin Xiaoqiang's question is that your large battery electrolyte has not been developed because the materials of the positive and negative electrodes of the battery have not been clarified, but now the Japanese battery technology copied by others should be no problem!

You must know that Japanese small-sized lithium batteries have been used in mobile phones and laptops for quite a long time.

"Well, we have actually figured out the electrolyte of this solid battery, and can manufacture it now. In fact, the solid electrolyte used in lithium batteries is actually peo polyethylene oxide. This material is used by the Japanese

It has been used for some time, and we can basically produce it now, but we are now developing a process for mass-producing this solid electrolyte. Once the development is successful, we will be able to mass-produce this substance."

Bin Xinwei quickly talked to Jin Xiaoqiang to explain.

Well, it sounds like this is still the case. It seems that these people have not been in vain, but this kind of solid electrolyte is only suitable for use in mobile phone batteries or laptop batteries.

The actual use in hybrid vehicles is not big at all. For the lithium batteries required by hybrid vehicles, liquid electrolyte and gel electrolyte are actually the key.

Especially gel electrolyte, this electrolyte is the key to the lithium batteries used in future hybrid vehicles!

The most elementary lithium batteries used in hybrid vehicles actually used liquid electrolytes at the earliest. This electrolyte is composed of an electrolyte based on lithium salt and a non-aqueous organic solvent based on carbonate.

However, the state of this liquid electrolyte is very unstable and requires a very safe working environment. If you are not careful, it can easily cause combustion or explosion.

As is often the case in later generations of hybrid vehicles, once the electrolyte leaks due to impact and rollover, it will be very easy to cause the car to burn and explode.

This is mainly because the organic solvent of carbonate contained in the electrolyte is a very flammable substance, and as the lithium-containing material of the positive electrode of lithium batteries, the lithium ions in it are very active.

When this positive electrode is working, it is very easy to release oxygen, and once this travel solvent is fully in contact with oxygen, it will release a large amount of heat and gas.

The heat and gas generated in this way will further intensify the decomposition of the positive electrode of the lithium battery, causing a vicious cycle. When the temperature reaches the melting point of the electrolyte, it will cause combustion or even explosion.

Later BYD electric cars burned and exploded, Chevrolet Volts burned and exploded, and other lithium batteries burned and exploded, all due to this principle.

So even seven years later, when people are promoting a large number of hybrid vehicles, consumers will not dare to buy such hybrid vehicles that use liquid electrolytes on a large scale because of concerns about the safety of lithium batteries.

It was not until later that a large number of gel electrolyte lithium batteries were widely promoted, which made hybrid vehicles safer.

So at this time, Jin Xiaoqiang paid great attention to the research and development of this gel electrolyte battery, because in his opinion, only this kind of gel electrolyte lithium battery will be the king of hybrid vehicles in the future.

A few years later, it was Hyundai, which had absorbed a lot of nutrients from the Chinese market, and was the first to assemble gel electrolyte lithium batteries into hybrid vehicles.

However, today's Hyundai has been beaten down by Huayang Dynamics. I'm afraid there won't be too many opportunities for such a leap forward development.

And with such an incredible figure as Jin Xiaoqiang, Huayang Power is very likely to become the first company to bring this gel battery to hybrid vehicles!
