Chapter 115
Kong Bai sat there with a smile, listening to the little loli chattering about what she saw, heard, and felt in Zhonghai, but the devil knew how much he listened to?
His mind kept wandering back and forth on his interesting new discoveries, and he didn't forget to use them to maximize battery performance, stability and size reduction, while nodding his head at Qiaoqiao and listening carefully.
In his research and development plan for the next two weeks, nuclear batteries have another important research and development direction, that is, relatively cheap, energy efficiency ratio is relatively moderate, but can be popularized to ordinary military personnel easy to carry, for the long-term continuous power supply of electronic equipment.
In Kong Bai's research, the selection of radioisotopes is the most important aspect of realizing miniature nuclear batteries.
The choice of which radioactive element, as the "fuel rod" of the miniature nuclear battery, mainly considers the type of radiation, release energy density, radioactivity ratio, price and half-life, and one of the most important considerations, that is, safety.
Gamma rays that escape from radioactive material have a strong ability to penetrate. Large doses of gamma irradiation, can directly damage the DNA structure of the human body, require a large volume of external shielding devices to reduce its harm, but will greatly increase the volume and weight of the battery.
α particles can cause solid semiconductors to generate electron-hole pairs, thereby releasing electric current, but can cause serious lattice defects, thereby reducing battery life.
The miniature nuclear battery, limited by its size, cannot use liquid crystal semiconductors, combined with the complex internal silicon carbide structure design, to solve this problem.
Therefore, the radioactive elements used in the "fuel rods" of miniature nuclear batteries, the most realistic choice, is the kind of element that can emit relatively pure β rays as much as possible!
In this way, the answer is just around the corner!
Nickel-63 has a radiation period of more than 100 years and is the element of choice for this nuclear battery "fuel rod".
Particles or electrons other than β rays emitted from nickel-63 have relatively low radiation ray energies, below the threshold energy of 200-250 kiloelectron volts that causes permanent damage to the silicon crystal structure.
On the other hand, nickel-63 can emit electrons with a maximum movement energy of 67 kiloelectron volts, which cannot penetrate the outer layer of human skin, which also ensures the safety of battery carriers.
Moreover, Kong Bai is also inspired by "nuclear energy diamonds", and in the design of this battery, a large number of miniature artificial diamonds can be added, thereby triggering microcurrents such as "nuclear diamonds"!
He plans to design this portable nuclear battery of nickel-63 into a layer-by-layer stacking structure, so as to effectively increase the output power of the battery.
Specifically, nickel-63 sheets with a thickness of about 5 microns are wrapped in two 10-micron-thick energy conversion devices composed of semiconductors and dense miniature artificial diamonds to form a sandwich-like internal battery structure.
By theoretically calculating the half-life and radiant energy of nickel-63, this nuclear battery will have an energy density of 3500mWh/g, more than 10 times that of traditional chemical batteries.
Coupled with a service life of up to 100 years, the increase in this nuclear battery compared with traditional chemical batteries is a thousand times, ten thousand times!
If the future processing technology can go further and make each layer of the structure thinner, then this battery has room to further improve performance!
The advantage of nickel-63 nuclear battery is that on the basis of strong performance, it is relatively cheap and cost-effective!
Of course, it is relatively expensive to the skyline super battery of "nuclear diamond", and if you compare it with the thorium-232 large nuclear battery, it is still a little expensive!
But the disadvantages are also obvious, once this battery is deliberately destroyed, the internal structure is exposed, it is still more dangerous, and it should not be realistic to popularize it to civilian use on a large scale!
However, as a portable military battery, it is completely fine!
Even if there is damage to the battery structure, with the management ability of the military organization, it is completely possible to deal with it in a timely manner without leaving a calamity!
Kong Bai is happier the more he thinks about it!
If this kind of battery is successfully developed, then more than a hundred times its own "super battery" will have another one!
It's so much fun!
Bai Qiaoqiao was happier the more he spoke, and Zhou Xiaomi also began to join the heated discussion!
Speaking of eating, drinking and having fun, Zhou Xiaona is definitely a big expert! The key is that people are still more particular about playing, comparing can play, and can play with taste!
Bai Qiaoqiao talked about what he saw and heard in Disney's No. 33 Club, describing how stylish, how dreamy, and how visual it was in cartoon scenes!
Zhou Xiaomi added some information on the side about the history of the hot No. 33 club, and the origin of some scenes in it, which is called a head is the Tao, citing scriptures.
Zhao Qiming pouted disapprovingly on the side, and said in his heart:
"Good guy! The entrance fee alone is nearly 180,000, and the annual membership fee is nearly 90,000!
"Fun and style, that's a must, rich people are not fools!"
"The key is that the contents are not delicious, and the amount is very small!"
"A few days ago, I accompanied these two to visit Disney, and I ate no less than 6 steaks in it alone, and I didn't think it was enough!"
"The only advantage is that with the status of club members, you don't have to huddle together and queue up, and you can save a lot of effort!"
Kong Bai was still nodding his head outside the wandering world, not knowing what these two people were talking about!
Only Dabai, who listened to it with relish, the kind of envy and eagerness on his face, anyone can see it!
Purely mentally speaking, Dabai has only been "born" for more than a month, and he is still a very curious and enthusiastic child character about everything!
Because of the particularity of her existence, she cannot walk around, see, and play at will, in fact, it may not be an ordeal for her.
Through the movie brought by Xiaomi's sister, she has an intuitive perceptual understanding of this objectively existing world, and she is also more curious about the wonderfulness outside!
At the same time, due to her special existence, the depth and perspective of thinking about problems and feeling things are particularly deep and extensive.
In her opinion, the complexity of the human world seems to be beyond her "imagination", in fact, it is beyond her computational deduction ability, but the more she is like this, the more interesting she feels, the more curious she feels, and she feels that she has a desire to integrate into human society!
Her level of wisdom may be very high, perhaps more than any current human being, but from her long-term relationship with Kong Bai and Zhou Xiaomi, she feels that there are aspects of human beings that are beyond her reach!
For example, the jumpiness of thinking, which was difficult for her to understand at first!
This is especially evident in the development of new technologies!
She didn't understand why Kong Bai could come up with so many means to solve problems without any data support and logical deduction, and leapfrog forward into the unknown field of knowledge?
Moreover, she didn't understand why Zhou Xiaomi could pull things apart when she saw a thing, implicating this matter with so many illogical things and implicating some inexplicable relationship?
Human beings are really strange intelligent creatures, what is the structure of their brains, why do they think so nonsensically?
This is the biggest problem that has been confusing her at the moment!
It is this confusion that triggers her greater curiosity about the entire human society!
Moreover, in this confusion, there is also an inferiority complex in it!
As she came into more contact with humans, she gradually felt an alienation, an emotion of being seen as alien inside.
Under the expressions of those who either admire or worship, there is a sense of freshness in looking at strange things, or more simply, the expression of looking at monsters!
Only these few people who are close to her, such as Brother Xiaobai, Sister Xiaomi, Brother Qiming, etc., they really treat themselves as a living "person", the kind of respect and care for her personality, the small actions of caring for her feelings, all make her feel very comfortable....
