In the end, two women and one man had a fierce game, and nothing came to fruition.

Ji Donglai didn't care about these before the final results came out, but came to Feng Chunbao's chip laboratory in the R&D center alone.

As the most gold-swallowing department in the entire R&D center, since its establishment, the average daily consumption of funds is 200,000 yuan, and the salary of researchers is still calculated separately.

According to Ji Donglai's requirements for sparing no effort to support chip technology, Jiang Haokun recently approved 30 million professional funds for Feng Chunbao, and transferred a bunch of people from the photovoltaic company's equipment company.

Jiang Haokun doesn't know much about chips, semiconductors and materials, and he came here just to take a look, and this time Ji Dong came to take a look in person.

Compared with the last time, this time the laboratory of the chip department has been expanded twice, all of which are dust-free environments, indoor 24-hour LED lighting, and constant temperature and humidity environments.

Access to the laboratory must have a strict iris examination, and no one is exempt.

Except for Ji Donglai and Jiang Haokun, no one in the company's top management can contact anyone here now, including Zhao Shuying and Xin Li.

The department's lounge, smoking room, and food area were all outside, and when Ji Dong came to change clothes, Feng Chunbao came out of the lounge.

"Mr. Ji, when did you come back?"

Seeing Ji Donglai change clothes, Feng Chunbao hurriedly came over to help Ji Donglai zip up the dust suit.

"Just a few days after I came back, I asked Ran Bo to put your gift outside, how are you doing, what good things have you found?"

Facing Feng Chunbao, who is very compatible with him in the company, Ji Donglai always has a smile in his eyes. The other party's hairline has moved back a lot now, his eyes are full of stories, and there are not many vicissitudes on his face.

"Yes, you must like this technology, we just made a sample, and Mr. Xiao Jiang has not reported it yet, which is a by-product of our research on chips."

"At the same time as the breakthrough in printing chip technology, we have synchronized a project with the materials group, and now we are also in our laboratory, and now we have made a major breakthrough."

"Now the samples we make are a little simple, but they can already meet the requirements for use, here!"

The two passed through the damper, and Feng Chunbao took Ji Donglai to the isolation door on the side, where several devices were being synchronized for experiments, the motor on the table was buzzing, and a timer was placed next to it.

"This is the motor of our drone, this is our latest large battery, which uses our atomic printing technology, and this is a breakthrough."

"We brought three electric motors with one battery, which were completely simulated in real combat. Now the electric motor has been working continuously for eight hours, and according to our original design intention, this battery can allow our twin-tailed scorpion drone to work continuously for twelve hours. ”

"Our best-performing drone is now traveling at a speed of two hundred kilometers per hour, and if it succeeds this time, we will be able to take off our drone from here to Seoul and turn back."

"If the plane takes off in Zhejiang, it will easily turn back over Guam, and if it takes off from Hainan, the whole of Hainan will be within our strike range. If it is from Sansha City, then the entire South China Sea is our backyard! ”

Feng Chunbao pointed to the map on the wall to explain to Ji Donglai, next to it was a model of the twin-tailed scorpion drone, which was also a model that Ji Donglai had devoted all his financial resources to break through.

Prototypes are still being improved, and the biggest obstacle in the past was battery technology. The problem of energy storage is a problem that the whole world is concerned about, and the batteries on the civilian equipment are mainly lead-acid, lithium iron phosphate, and ternary lithium batteries.

Either way, there is a fatal problem, if you want to have a large capacity, you must have a large volume.

This is a fatal flaw in the drone, and a revolution in battery technology is necessary to increase the bomb load. In the past few years, Ji Donglai has been looking for related technologies through the alumni association of the University of Science and Technology, and several large battery foundries in China have been looking for people to try to cooperate.

Either there is no corresponding technology, or they refuse to cooperate, after all, people are not short of money. Ji Donglai and Jiang Haokun said that the photovoltaic group is also secretly making efforts, according to Ji Donglai's estimate, it will take at least five years to make a breakthrough, and now it is still beneficial to see that there is no restriction on money.

"What kind of technology is this?"

At present, the speed of the twin-tailed scorpion drone can reach 240 kilometers per hour, and it can even exceed 300 when it really needs to get rid of it.

It's just that the fuselage is still making a carrier with higher strength, and several doctors from Beihang University are jointly developing it with the laboratory of Capital University of Technology.

"Graphene, a very popular concept in the first two years. Everyone knows that this thing is high energy storage, but it is too difficult to prepare. It just so happened that we made the equipment for the second generation of chip printing technology, and we improved it, and then it became like this ......."

Looking at Ji Donglai's expression, Feng Chunbao knew that Ji Donglai had taken a heart and took Ji Donglai to the laboratory on the other side.

At this time, a roll of transparent material on the equipment was slowly being pulled out of the equipment, Feng Chunbao picked up a roll of film material next to him, took the scissors and cut a piece and handed it to Ji Donglai.

"Mr. Ji, take a look under the microscope, this is a ten-layer graphene film that we printed using dielectric technology and vapor deposition technology, and our battery is made of these panels composite together, and then connected by graphene electrodes."

"This technology still has some shortcomings, and it can't reach the industrial level of mass production for the time being, but the laboratory level is still okay. If we can reach the industrial level, then we can develop into the super battery technology market and lead a new technological revolution. ”

"At present, our unmanned submarines can also apply this battery, and the initial test is still possible. In a low-temperature and closed environment, the application performance of the battery is better! ”

Pointing to the rolls of waste in the waste recycling bag, Feng Chunbao said with some excitement.

In front of the whole plant, the finished product area is a green box, the defective box is a yellow box, and the waste product is a red box. The recycling bags below are also available in three colors, with the red bags always full.

According to Feng Chunbao's design, graphene batteries are stacked in multiple layers, which can be cut into various sizes and shapes according to the finished material, and if it is not for this, the loss will be even greater.

Ji Donglai took the flake graphene and glanced at it under the electron microscope, and the dense crystalline hexagons on it were neatly arranged, just like a honeycomb.

Occasionally, there are some irregularities, just sporadic points, according to the rules set by Feng Chunbao's gang, this product is already qualified.
