Space technology conference room.

"Chairman Liu, this time we will get straight to the point. "The first to speak was Zhan Ming.

"Mr. Zhan, please speak. Liu Long, who was sitting firmly in Diaoyutai, said casually.

"Liu Dong, I don't know if I can take a look at the sample for a 50 times graphene battery. "In line with the road of seeking wealth and nobility in stability, Zhan Ming still wants to take a look at the real thing, not that Zhan Ming doesn't believe Liu Long, but I heard that the difference between the tactile senses and the personal experience is too big, and the most important thing is that the 50 times graphene battery is at least 20 years ahead of the world, a proper black technology.

"Even if Mr. Zhan doesn't say it, he will show it later, but I didn't expect Mr. Zhan to be so anxious. After Liu Long finished speaking, he gestured to Liu Guan.

"Liu Dong, this is not in a hurry, there is no doubt about the strength of Liu Dong and space technology, after all, 50 times graphene batteries are proper black technology, if you don't hurry up and see it, my heart is like a cat scratching." ”

"It seems that Mr. Zhan is also a man of temperament. Liu Long gestured to Liu Guan again, and Liu Guan, who was standing in the first place, began to demonstrate.

I saw Liu Guan take out a battery similar to the size of a mobile phone battery from the bag, and then took out the testing instrument, and the data on the display screen was directly displayed in front of everyone.

"The standard voltage is 48 volts and the capacity is 200,000 milliamps. ”

"It's incredible that such a small battery can store 200,000 milliamps, and it is 48 volts, not 3.85 volts. Liu Shi, who was a little surprised, said dumbfounded.

This data brought a deep shock to both Zhan Ming and the four officers.

In line with inertial thinking, they always thought it was a 3.85-volt 200,000 mAh battery, but they never expected it to be 48-volt, and the gap was insignificant.

Friends who are familiar with physics know that circuits are divided into parallel and series, in parallel circuits, the trunk current is equal to the sum of the currents of each branch, the voltage at both ends of each branch is equal and equal to the power supply voltage, and in the series circuit, the current of each part of the circuit is equal, and the total voltage is equal to the sum of the voltages of each part.

If it is a voltage of 3.85 volts, if you want to form a voltage of 48 volts, you need at least 12 batteries, which means that the battery shown by Liu Guan at this moment is 12 times higher than the graphene battery they thought in their hearts.

Zhan Ming, who was a little excited, said, "Liu Dong, 50 times the graphene battery is 48 volts. ”

"I don't think I told you it's 3.85 volts. Liu Long glanced at Zhan Ming and said, and at the same time said with contempt in his heart, "Look at the appearance of the world, if you know the existence of 10,000 times graphene batteries, I don't know what will happen." ”

"That Liu Dong, I have a preconceived idea, you continue. ”

"This battery, the number of charging and discharging times is 10 times that of lithium battery, it can be charged and discharged arbitrarily in the range of minus 80 degrees Celsius and minus 200 degrees, as for his safety, it can be said that it is dozens of times that of lithium battery, even if you damage the battery, at most it is a ***, let's take a look at his charging time. ”

Liu Guan said and took out a power supply similar to a mobile phone charger, and then took out a graphene battery without electricity, and plugged it in under everyone's attention.

The power supply display shows the charging data, and after about five minutes, the power supply display shows that the charging is complete.

"It's incredible that such a large capacity can be charged for five minutes. Lieutenant General Liu Shi stood up and walked to Liu Guan's side, observing the graphene battery.

"Liu Dong, if the battery is connected in series or parallel, will it still take five minutes to charge? ”

"Yes, but you need to customize the corresponding adapter, haven't you heard that graphene batteries also have another name, five-minute batteries. Liu Long said stinkily.

"Dong Liu, I really don't know what else you can't develop in space technology. The excited Zhan Ming gave Liu Long a thumbs up.

Mr. Zhan praised it. ”

Liu Shi, who returned to his seat, said to Liu Long: "Liu Dong, then let's talk about the cooperation of graphene batteries." ”

"I don't know in what way the military wants to cooperate. When Liu Long heard that he was about to get to the point, he also cheered up.

"Liu Dong, if you can, our military wants to buy the formula of 50 times the graphene battery. ”

After hearing Liu Shi's words, Liu Long suddenly felt that the whole person was not good, in fact, he also wanted to sell the formula to the military, but there is a premise in this, that is, graphene materials with atomic thickness, these materials are directly produced from the atomic smelting factory in the subspace, and the raw materials are still the key to the key, and it is really unrealistic to sell the formula without revealing the secret.

"General Liu, it's a joke, I don't think I want to mention the buying and selling of formulas, after all, I still have to rely on graphene batteries to feed the company's large group of people. ”

"Liu Dong, we can guarantee that if we sell the formula, we will only supply it for military needs, and as for the civilian market, we will not get involved. ”

"General Liu, let me take the liberty of asking, can you make cheap atomic-thick graphene? ”

After listening to Liu Long's words, Liu Shi looked towards the three colonel officers.

"Chief, with the current technology of our country, there is no way to make graphene with atomic thickness. One of the senior colonels said cautiously to Liu Shi.

After hearing the words of the colonel, Liu Shi suddenly felt embarrassed to his grandmother's house, a country's scientific research level is not as good as a company, originally when Liu Shi came, he was a little contemptuous of Liu Long or space technology, one is because Liu Long is too young, and the other is that space technology is too young, such a young company has launched 10 times or even developed 50 times the graphene battery.

His idea, probably because of shit luck, Liu Long developed artificial intelligence, and the graphene battery designation was completed by artificial intelligence, but now Huaguo also has Pangu, for graphene batteries, it can be said that it is only a matter of time.

Unexpectedly, the results he heard disappointed him.

"Chairman Liu, we can buy atom-thick graphene from your company. ”

"General Liu, let me tell you this, our graphene battery production line is fully intelligent, as long as the graphene with atomic thickness is put into the feed port, and then the finished product is collected at the discharge port, and the operation of feeding and discharging is all completed by industrial robots, which can be said to be an unmanned production line, if the country wants to buy the formula, I don't feel that it makes much sense." ”

After listening to Liu Long's words, the five people present suddenly became petrified, what an unmanned production line, the feed port transports raw materials, and the direct discharge port collects the finished product, should it be so tall, this is 50 times the graphene battery, for today's world, a proper black technology.

At this time, the thoughts of the five people can be said to be roughly the same, and at the same time full of incredible.
