For the next period of time, Gu Dong spent the busy time, and the small spider robot repaired the damaged robot.

If possible, repair it.

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

Perhaps because the original permissions of the Third Institute no longer exist, these robots are currently following his orders.

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

The underground warehouse still cannot enter, the door cannot be opened, and I don’t know which door is made of which material. Even if Gu Dong attacks with a pulse rifle, it still cannot 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 down before talking.

While learning the alien knowledge in Xiaoling's database, he waited for Xiaoling to read out the third intelligent brain database.

According to Xiao Ling, the third intelligent brain database has a lot of data, and since most of it is damaged, it is slow to read.

Xiao Ling is not a large intelligent brain, but just an ordinary robot, so after nearly three days of use, Xiao Ling replied to Gu Dong some information.

What surprised Gu Dong was that the Third Intelligent Brain did 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.

Alien batteries are not lithium batteries at all, but pure energy batteries, which are extremely high-end. Their manufacturing methods come from controlled nuclear fusion.

Gu Dong was not sure what controlled nuclear fusion is at first, but after going back and checking, what exactly does the word automatic mean?

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

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

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

The technology required for nuclear fusion is much higher than that of nuclear fission, and humans have not yet achieved controllable nuclear fusion.

The reason why the sun constantly emits heat is because of the continuous nuclear fusion, so there is another joke called controlled nuclear fusion, that is, the artificial sun.

When Gu Dong heard that alien batteries involved controlled nuclear fusion, he felt a little cold in his heart.

"Is there any other information about batteries?" Gu Dong immediately stared at Xiao Ling and asked.

He wants other information!

He obviously can't do alien batteries, and they involve too many cutting-edge technologies, so he can only consider lower-level ones.

"Master, there are three battery manufacturing methods in the Third Intelligent Brain. Given the lithium battery manufacturing solution you provide, Xiaoling suggests that you try to develop an atomic battery. This battery is much better than a lithium battery!" Xiaoling said: "I searched for atomic battery manufacturing materials in the Third Intelligent Brain database, you can check it!"

Lights appeared on its head and shone on the wall next to it, and a series of information appeared on it.

Gu Dong glanced at him and couldn't help but feel amused.

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

However, this kind of battery is not safe, and the materials used are all radioactive isotopes, which are very dangerous. If you absorb it a little, it will cause cancer, so he doesn't want to develop it.

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

He now has not much capital on Earth. If he can be a little lower, then try to be a little lower. The simpler the better.

He knew that even the simplest way to manufacture batteries in the science and technology city was probably much higher than that on earth.

Xiao Ling was silent for a moment and said, "There is indeed another way. But the Third Institute has given up on the development of this method. It is a polymeric material battery."

Gu Dong was slightly stunned: "Polymer material battery?"

Xiaoling nodded and said, "Yes! But it also has a name, also called graphene polymeric material battery. It mainly uses the characteristics of lithium ions to quickly and large-scale shuttle movement between the graphene surface and the electrode to create an intermediate energy battery."

"Since the energy it can store is much lower than that of a multi-ring energy battery, it was abandoned for use 3,200 years ago. Master, relatively speaking, this 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 of battery materials on the earth a few days ago, and naturally knew what graphene represents.

It's not just a matter of battery capacity.

It is said that the charging speed and discharge speed of this graphene polymeric material battery are much larger than that of ordinary batteries.

There is a saying that this kind of battery can charge for ten minutes and run a thousand kilometers, and the charging speed is one thousand times that of ordinary batteries.

The discharge speed is ten to twenty times higher than that of ordinary lithium batteries.

Graphene is known as a new material that can completely change the 21st century.

This material has many points, such as high conductivity, high strength, ultra-light and thinness, ultra-transparency and flexibility, low price, etc.

In many countries, enterprises have invested huge amounts of money to study.

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

Gu Dong didn't expect that there was information on this host, so he was overjoyed and immediately said: "Change out the manufacturing method of this battery immediately and show it to me!"

"Okay!" Xiao Ling looked at him and continued: "If the owner wants to make a polymeric material battery, this is a good idea. Although it has been eliminated, it still has a high energy storage."

Looking at the dense text and graphic introductions, Gu Dong became more and more excited and immediately looked carefully.

But soon, Gu Dong frowned.

The things that Xiao Ling presents are quite complex and require some large instruments to cooperate with the development. The most important difficulty involved is the manufacturing of large-area and high-quality graphene.

It is not difficult to obtain graphene, because the raw material for obtaining graphene is graphite, which is very cheap. However, it is very difficult to manufacture large-area and high-quality graphene, which is also the main reason why people on earth have not yet produced graphene batteries on a large scale.

The various top performances of graphene can only be reflected when the quality of graphene is very high. With the increase 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 superimposed 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 oxidizing graphite.

The specific operation process is to use strong oxidizing agents such as concentrated sulfuric acid, concentrated nitric acid, potassium permanganate, etc. to oxidize graphite into graphite oxide.
