Chapter 709 Lithium-air battery also breaks through

In the following chat, Jiang Bo learned some basic performance and data about bionic robots from Zhou Shupei.

The robot was created. After covering a layer of bionic skin, it was almost exactly the same as a real person in terms of touch, temperature and vision, and the simulation level reached more than 99.99.

Even compared to those who have had plastic surgery, they look more like real people.

Moreover, previous problems such as sports friction and vocalization have been solved one by one.

The robots we have built now can be put into real society and help humans relieve work pressure.

For example, farming, sanitation, delivery of express delivery and takeaway, industrial development, etc.

Zhou Shupei even said that if the robot can be given an ID card, they can also enter the entertainment industry to develop.

However, there are also disadvantages.

First, all machinery has one thing in common, that is, it is easy to damage.

Second, robots represent the peak level of modern industry and are difficult to manufacture.

Third, it is expensive. A robot like "Monday" requires millions of rmbs.

Of course, Zhou Shupei also said that if a robot factory is opened and the assembly line is established, the cost will plummet, but it is still unclear how much it will drop.

Fourth, because we want to imitate humans, and the chip will be installed inside the robot instead of hiding it in the cloud, the power consumption of this type of bionic robot is very terrifying.

Under normal circumstances, a bionic robot weighs 75kg, of which 30kg is a battery pack. However, with the current energy density of 200wh/kg of lithium-ion batteries, a 30kg battery has only 6kwh of energy storage, which is 6 degrees.

With the power of 1.2kw of the robot, it will run out of power after 5 hours of continuous operation, and it will not even meet the standards for continuous operation.

Of course, if the weight of the robot's battery pack is increased, the battery capacity can be increased. However, the fact is that the larger the weight of the robot, the greater the load, the greater the power, and the larger the volume, the dissonance and instability will gradually increase.

Therefore, according to Zhou Shupei's meaning, robots in human form still use 75kg as the perfect standard, and it doesn't matter if robots in other forms.

Fifth, the commercial use of bionic robots will inevitably cause a large number of ordinary people at the bottom to lose their jobs, which is a big problem.

Although the state has approved research and commercial use in this area, when robots replaced workers in factories, couriers and takeaways, sweepers and farmers, doctors and construction workers...

The unemployed population in the whole society will be counted in tens of millions or even hundreds of millions.

At this time, if there is no new industry to accept these people, the world will be in turmoil. An unprecedented and unpredictable change will sweep across China and then spread throughout the world...

After chatting with Zhou Shupei, Jiang Bo found that there were only two problems that actually need to be solved.

One is the problem of mass production. Some materials are relatively expensive and rare, such as bionic skin, such as robot chips, and robot ultra-high-precision components.

Another is the battery capacity issue.

But just so happens that among these two problems, the battery capacity is being solved by black bones, and lithium-air batteries can perfectly solve it.

The accuracy of robot components is related to CNC machine tools, and Yang Kuishan is also developing and manufacturing.

The rest of the problem of skin and chips does not seem to be very difficult. The skin is technical. Although Black Bones do not have the technology for chips, they can find someone to manufacture them.

...

After leaving Zhou Shupei's laboratory, Jiang Bo came to the fullerene engineering laboratory again. Because Zheng Shouyi's place is relatively large, He Tianqiang's research was carried out here before the laboratory was built.

Jiang Bo came to the laboratory and found more than a dozen researchers gathered together and said something excitedly.

When he got closer, Jiang Bo raised his eyebrows slightly.

"The results of the 38th experiment have come out!"

"Compared with the last time, our specific energy was charged 2,000 times, and the energy density remained above 700, and the capacity was still as high as 97.2%!"

"This is too strong. The average energy density of ternary batteries on the market is still at 200wh/kg. Even if the energy density of Tesla batteries is, our lithium-air batteries can do it. However, Professor He sets the standard of 1,200wh/kg. After charging and discharging for 2,000 times, the energy density of the battery can no longer be lower than the original 97%..."

"If we can really make lithium-air batteries to the standards set by Professor He, then all the lithium-ion batteries on the market will be eliminated!"

"What did you say? With the energy density of 720wh/kg now, they can't compare, right?"

"Professor He is so amazing. When I came here two months ago, I never thought that lithium-air batteries could be successful."

"Who said no? I was thinking about being a scattered person at that time, but now I have no idea."

“…”

After listening for a while, Jiang Bo smiled and said to himself: "The energy density of lithium-air batteries has reached 720wh/kg, and it has made a lot of progress."

After passing through the laboratory, Jiang Bo entered the inner room and found He Tianqiang who was reading the information.

"Mr. Jiang, why are you here? Please sit down quickly." When He Tianqiang saw Jiang Bo, he hurriedly asked him to sit down.

"I'll come and see your research progress. I just heard from those researchers outside that the energy density of lithium-air batteries has reached Jiangbodao.

He Tianqiang smiled and said, "That's right, compared with the ternary batteries on the market, our energy to materials ratio has been more than three times that of them. Even Tesla, which has the best power battery, our battery energy density is still more than twice that of them.

However, I divided it into three stages of lithium-air batteries. The standard for the first stage is that although I have a breakthrough, it is still a little short of a real breakthrough."

"How long will this breakthrough of 1200wh/kg take?"

"Today is March 5th. If nothing unexpected happens, it will be basically completed in early April."

"So fast?"

"Yes, this is thanks to the information provided by the company." He Tianqiang said with emotion: "The principle of lithium-air batteries is actually very clear. As long as the problems of lithium dendrites and targeted transport of oxygen molecules, battery explosions, service life and side reactions in the battery can basically be solved.

As for oxygen enrichment, the data also mentions a technology to create a difference in internal and external oxygen concentrations for rapid enrichment, which is very useful.

The experimental research we are currently conducting is actually trying to optimize the battery components and improve energy density. As long as we continue to advance step by step, we can easily find a breakthrough."

Jiang Bo asked again: "As a result, the lithium-air battery technology has basically achieved a breakthrough here, right?"

He Tianqiang nodded: "Yes, the technology is fine, but there is still a lot of room for improvement. You also know that the specific energy of lithium-air batteries is very high. In theory, we can reach a theoretical height, but I think it is possible to continue researching it, 2kwh/kg is possible. However, the data only provides the technology to realize lithium-air batteries, and does not provide a solution to increase the specific energy of lithium-air batteries. We need to study and improve it ourselves."
