For the next period of time, Gu Dong spent his time busy, and the small spider robot went to repair the damaged robot.

If you can fix it, you can fix it.

Gu Dong tried to activate more robots for his own use.

Perhaps because the original authority of Research Institute 3 no longer exists, the robots are currently acting on his orders.

With the help of a large number of robots, he has cleared the factory aside.

The underground warehouse still can't be entered, the door can't be opened, and I don't know which door is actually made of what material, even if Gu Dong attacks with a pulse rifle, it still can't be opened.

He knew that there must be a lot of things in the warehouse, but there was no way to open it, so he could only press it later.

While learning the alien knowledge in Xiao Ling's database, he waited for Xiao Ling to read out the database of the Third Brain.

According to Xiao Ling, the Third Intelligence Brain database has a lot of data, and because most of it is damaged, it is relatively slow to read.

Xiao Ling is not a large intelligent brain, but just an ordinary robot, so it took nearly three days before Xiao Ling gave Gu Dong some information.

To Gu Dong's surprise, the Third Brain does have the technology and steps to develop and manufacture energy batteries, but what disappointed him was that the technology of manufacturing alien batteries was very difficult.

The alien battery, which is not a lithium battery at all, but a pure energy battery, is extremely high-end, and its manufacturing method is derived from controlled nuclear fusion.

What controlled nuclear fusion is, Gu Dong didn't know at first, but after going back and checking it, what exactly did the word automatic mean with him.

This can be regarded as one of the biggest problems for earthlings.

Nuclear energy includes two main forms: fission energy and fusion energy.

Nuclear fission is the huge energy released by the atoms of heavy metal elements through fission, and human beings have used it, that is, to build nuclear bombs.

Nuclear fusion requires much more technology than nuclear fission, and so far mankind has not yet achieved controlled nuclear fusion.

The reason why the sun continues to emit heat is because of continuous nuclear fusion, so controlled nuclear fusion has another nickname, that is, artificial sun.

Hearing that alien batteries involved controlled nuclear fusion, Gu Dong's heart suddenly cooled,

"Is there anything else?, is there any other information about the battery?" Gu Dong immediately stared at Xiao Ling and asked.

He wanted to get other information!

Alien batteries, he obviously can't make them, there are too many cutting-edge technologies involved, so he can only consider low-level ones.

"Master, there are three ways to make batteries in the Third Brain. In view of the lithium battery manufacturing solution you provide, Xiaoling suggests that you try to develop atomic batteries. This kind of battery is far better than lithium batteries!" Xiao Ling said: "I searched for a material for the manufacture of atomic batteries in the database of the Third Brain, you can check it!"

Streams of light came out of its head and shone on the wall next to it, only to see a barrage of messages appear on it.

Gu Dong glanced at it and couldn't help crying and laughing.

Atomic batteries, also known as radioisotope batteries, are also known as nuclear batteries, which have been available on Earth for a long time.

It's just that this kind of battery is not safe, and the materials used are all radioactive isotopes, which are very dangerous, and if they are absorbed by a little human, they will cause cancer, so he doesn't want to develop them.

"Is there anything more low-level?" Gu Dong continued to ask.

He doesn't have much capital on Earth now, if he can be a little low-level, then try to be as low-level as possible, the simpler the better.

He knew that even the simplest way to make batteries in Technopolis was much higher than on Earth.

Xiao Ling was silent for a moment and said, "There is indeed another way. But this method has been abandoned by the Third Research Institute to develop, it is a polymeric material battery. ”

Gu Dong was slightly stunned in his heart: "Polymeric material battery?"

Xiao Ling nodded and said: "Yes, but it also has a name, also known as graphene polymeric material battery, which is mainly a kind of intermediate energy battery made by using the characteristics of lithium ions to shuttle rapidly and heavily between the graphene surface and the electrodes." ”

"Because it can store much less energy than a multi-ring energy battery, it was abandoned 3,200 years ago. Owner, relatively speaking, this kind of battery is much more advanced than the lithium battery on the earth. With the same volume, the battery capacity it can provide is thirty to fifty times that of ordinary lithium batteries on the earth!"

When Gu Dong heard this, he couldn't help but be overjoyed.

He read a lot about battery materials on the earth a few days ago, and naturally knows what graphene represents.

It's not just about battery capacity.

It is said that the charging and discharging speed of this graphene polymer material battery is much greater than that of ordinary batteries.

There is a saying that such a battery is capable of charging for ten minutes, running a thousand kilometers, and charging a thousand times faster than a normal battery.

And the discharge speed is also ten to twenty times higher than that of ordinary lithium batteries.

Graphene has been hailed as a new material that can revolutionize the 21st century.

This material has many advantages, such as high electrical conductivity, high strength, ultra-thin and lightweight, super light transmittance and flexibility, and low price.

Many countries and companies have invested huge sums of money in research.

It can not only make batteries, but also make chips, make touch screens, etc., and can be used in a wide range.

Gu Dong didn't expect that there was this information in this host, and he was overjoyed, and immediately said: "Immediately tune out the manufacturing method of this battery and show me!"

"Okay!" Xiao Ling looked at him and continued, "If the master wants to make polymeric material batteries, this is a good way. Although it has been phased out, it still has a high energy reserve. ”

Looking at the dense text and graphic introduction, Gu Dong became more and more excited in his heart, and immediately read it carefully.

But soon, Gu Dong frowned.

Xiaoling's presentation is quite complex, requiring some large-scale instruments to cooperate with the development, and the main difficulty involved is to manufacture large-area and high-quality graphene.

It is not very difficult to obtain graphene, because the raw material for the production of graphene is graphite, and the price is very low, but it is very difficult to manufacture large-area and high-quality graphene, which is the main reason why the earthlings have not yet produced graphene batteries on a large scale.

The top properties of graphene can only be reflected when the quality of graphene is very high, and with the increase of the number of layers and the accumulation of internal defects, many of the superior properties of graphene will be reduced. ，

Therefore, if you want to obtain high-quality graphene, you need to reduce the number of stacked layers as much as possible and improve the quality.

In Xiaoling's information, there is indeed a way to improve the quality of graphene, which is mainly obtained by graphite oxide.

The specific operation process is to oxidize graphite into graphite oxide with strong oxidants concentrated sulfuric acid, concentrated nitric acid, potassium permanganate, etc.

The oxidation process is to intersperse some oxygen-containing functional groups between the graphite layers, thereby increasing the spacing of the graphite layers, and then after a period of ultrasonic treatment, a single layer or several layers of graphene oxide can be formed, and then graphene oxide is reduced to graphene with strong reducing agents hydrazine hydrate and sodium borohydride.
