It took him five days to build five laboratory versions of electromagnetic guns. The power of each electromagnetic gun has been tested, but it is still a little bit behind.

The power is sufficient, but the accuracy, cost control, miniaturization and enlargement have not yet been improved.

The miniaturized electromagnetic gun is naturally used for individual combat.

This thing is like an ordinary pistol. How to make an electromagnetic gun into an electromagnetic gun, and the power must be comparable to that of a pistol. The accuracy, recoil, etc. need to be no different from a pistol.

The degree of difficulty is not low, and this is the step Zhou Jimin wants to complete most.

However, the battery level is the biggest technical difficulty.

Immediately, Zhou Jimin walked out of the laboratory and came to the drone laboratory in Oasis New City.

"Xiao Wang, where is your lithium-air battery technology research at now?"

"Professor Zhou, you are here."

The researcher wearing glasses with thousands of degrees of myopia saw Zhou Jimin coming and said hello quickly.

Previously, Zhou Jimin had given technical explanations on lithium-air battery research, and even subsequently, he also conducted research in this area himself.

However, the current progress is not fast, so I wanted to come to the laboratory to inquire about the situation.

After some questioning, Zhou Jimin encouraged these researchers and then left disappointed.

In fact, the battery technology developed by their laboratories has reached the most advanced level in the world.

Just like a previously developed small drone that can fly continuously for forty-five minutes, it has unparalleled advantages in street fighting and other aspects.

And some large UAVs can also last for about three hours and can perform some short-distance reconnaissance missions.

However, these battery technologies are amazing, but they are far from meeting Zhou Jimin’s requirements.

In other words, it is far from meeting the basic technical requirements of electromagnetic guns.

If the electromagnetic gun wants to maintain a certain endurance and shooting power without adding too much weight, the requirements for battery technology are very abnormal.

"What materials should be used instead?"

Half a month has passed, and Zhou Jimin is now obsessed with lithium-air battery technology.

According to the actual half-month period, more than two months have passed since he was in the space.

Long before, his research on lithium-air batteries had already reached an extremely advanced level.

According to the battery technology of the finished small drone they came up with in the laboratory, which can last forty-five minutes, the battery technology that Zhou Jimin came up with can last up to ninety minutes.

However, with this kind of battery technology, in an electromagnetic gun, while maintaining sufficient power and weighing as much as two pistols, the battery life can only last for two bullets.

Therefore, Zhou Jimin is very dissatisfied with such battery technology.

An electromagnetic gun, not to mention the cost of making it, can only shoot two bullets, which is obviously not enough.

The most terrible thing is that the weight of the electromagnetic gun is twice that of an ordinary pistol, which is also a fatal flaw.

Such a laboratory product that was beaten with a pistol is naturally unacceptable to Zhou Jimin, who pursues perfection.

In the space laboratory, Zhou Jimin reflected again and again, searching for possible substitute materials or technologies in his mind.

"Forget it, let's go out and relax for a while, I'm too nervous."

Thinking of this, Zhou Jimin left the space first.

He gave himself two days of vacation. During these two days, he went to a small island in the south, flew to Great Britain, and visited a bald eagle.

Finally, I went directly to space and stood in space looking at the earth.

The pressure the earth gives him is very huge.

Because the orbit he is in is only more than 400 kilometers away from the ground.

From this distance, he was like an ant looking up at an elephant.

After returning from space, Zhou Jimin plunged into the laboratory again.

In fact, up to now, the matter of serving cups in front of Du Jianmin and his son that day is no longer a big deal.

He is just being serious with himself.
