"What is this?" Li Haoyu perked up and immediately asked.

Xiao Yu immediately replied, "My dear master, you go and show me a piece of this stone, I need to analyze the composition of this stone closely." ”

Li Haoyu asked in surprise: "Xiaoyu, can you still analyze the composition of this stone?" How did I never know the truth! ”

Xiaoyu glanced at Li Haoyu and said: "I've been bored these days and collected the data of many items on the earth on the Internet, and made a very large database. ”

When Li Haoyu heard this, he immediately ran over and picked up a piece of this colored stone and held it in his hand, and said to Xiaoyu in his heart: "Xiaoyu, you can start testing." ”

"My dear master, rest assured, as long as there are elements on the earth, I can check them out." Xiaoyu didn't make much movement, and a filament that was smaller than a hair suddenly poked out from the side of the Patek Philippe watch that Li Haoyu was wearing on his left wrist that was transformed from a super game editor, if Li Haoyu hadn't been paying attention, he wouldn't have noticed anything abnormal about this watch, and the filament tied the colored stone in Li Haoyu's hand several times before stopping.

"Li, these stones are so beautiful, if you can use this stone to build a rockery in my yard, it will be too beautiful." Emily held several colored stones in her hands, her eyes searching for stones that were more beautiful than those in her hands.

Li Haoyu showed a smile on his face, after all, she is a woman, and she still does not forget the pursuit of beauty in this situation.

"Li, do you think this stone is beautiful or this stone is beautiful?" Emily searched for a long time in the pile of stones, and finally found the two stones that best matched her heart, but she couldn't tell which one was the most beautiful for a while, so she took them to Li Haoyu and asked him to judge.

Li Haoyu glanced at the stone in Emily's hand twice, in his opinion, there was actually no difference between the two stones, but he saw Emily looking at him with blank eyes, pretending to appreciate it for a while, and then pointed to the colored stone in Emily's left hand and said, "I think this piece is more beautiful." ”

Emily was pleasantly surprised: "Lee, I also think this piece is very good-looking!" ”

Li Haoyu couldn't cry or laugh, now it seems that his life should be saved for the time being, and some Emily is going to play happily.

A quarter of an hour passed, and Xiao Yu's eyes were unbearably excited: "My dear master, the composition of this stone has been figured out, the outermost layer is a thin layer of lead element, and most of it is astatine element!" ”

"Xiaoyu, what is the astatine element?"

Looking at the excited Xiaoyu, Li Haoyu was a little strange, he probably knew what the lead element was. This thing can be protected from radiation and corrosion, but it cannot be exposed to it for a long time, otherwise it is easy to cause lead poisoning in the body. As for what the astatine element Xiao Yu said, his eyes were black, and he felt as if he had heard of this name somewhere, and he couldn't remember it for a while.

Xiao Yu's little face flushed with excitement, and said: "Astatine is a halogen chemical element, its chemical symbol is At, atomic number 85, atomic weight 210, peripheral electronic configuration 6s26p5, located in the sixth period VII.A group. It is an extremely unstable element, with about 25 isotopes, all of which are radioactive, of which the most stable 210At has the longest half-life of only 8.3 hours. The original word for astatine means "unstable". The total amount of astatine in the earth's crust is less than 28.35 grams, and it is mostly the metamorphosis product of natural radioactive elements such as radium, actinium, thorium, etc. Astatine for research is synthesized by bombarding the nucleus of bismuth with high-energy α particles. ”

Li Haoyu was stunned when he heard this, and then he remembered that there seemed to be such an element in the periodic table he memorized in high school before, and he didn't know what this element was for. I finally waited until Xiao Yu finished speaking before asking: "Xiao Yu, although the content of this astatine element in the earth's crust is very small according to what you say, it can already be synthesized artificially, even if it is rare, it is not valuable, right?" ”

Xiao Yu chuckled and said, "Although the synthetic astatine element has the characteristics of most of the natural astatine elements, there is one most important characteristic that the synthetic astatine element does not have!" My dear master, with so many natural astatine elements, you can monopolize the battery industry in the world in the future! ”

Li Haoyu was shocked, and hurriedly asked: "Xiaoyu, what characteristics does the synthetic astatine element lack compared to the natural astatine element?" ”

Xiao Yu smiled proudly and said: "My dear master, the natural astatine element is more than the synthetic battery, that is that it can lose itself with a negligible mass can release energy stably and continuously, compared to lithium-ion, the performance of astatine is at least 20 to 25 times that of the current lithium-ion battery, if the material of the positive and negative electrodes of the battery is further strengthened, the efficiency will be higher!" ”

"Xiaoyu, do you mean that if you use an astatine battery, the current smartphone can be used for at least half a month?" Li Haoyu was shocked by Xiaoyu's words, if what he said is true, then he can indeed monopolize the battery industry in the world.

"Of course, my dear master, I will not lie to you. This astatine is a naturally occurring radioactive substance, but fortunately it is covered with a layer of lead, otherwise not only would there be no animals here, but even these plants would have died from excessive radioactive radiation! ”

Hearing what Xiao Yu said so terrifyingly, Li Haoyu hurriedly threw the colored stone in his hand out, took several steps back in a row, and said, "Xiao Yu, why didn't you say it earlier?" ”

Xiao Yu said pitifully: "My dear master, I already told you when I got the results of the examination just now!" In fact, there is a layer of lead on the outside, and it is not a big deal for the human body to come into contact with it for a short time, and the animals here are all out of this place because they instinctively sense the danger here. ”

Li Haoyu breathed a sigh of relief, otherwise he was really afraid that he would die of a painful death after being irradiated with a strange disease, thinking of the wonderful prospect depicted by Xiaoyu, Li Haoyu's gaze when he looked at these colored stones now has changed, where is this a pile of stones, this is simply a golden mountain!

The development of mobile phone batteries has been moving towards a more environmentally friendly and endurance route from the previous nickel-cadmium battery to nickel-metal hydride battery to lithium-ion and today's polymer lithium-ion battery. In today's multiplicity of mobile phone applications, without better power support, it really can't bring users a better experience in the intelligent era.

Nowadays, smartphones are becoming more and more popular, and today's young people are embarrassed to go out if they don't have a smartphone, and the speed of hardware replacement of smartphones is staggering. In less than ten years, the performance of smartphones has improved both qualitatively and quantitatively, and "Moore's Law" is no longer enough to describe the speed at which the hardware parameters of smartphones have improved.

As a crucial part of smartphones, the battery life of mobile phones is not much worse than when smartphones were first launched ten years ago, and the battery capacity is the short foot of all mobile phone companies. Although the current polymer lithium battery can be regarded as the third generation of mobile phone batteries, the battery life has not been significantly improved.

Anyone who has played with a smartphone knows that the battery of a smartphone is too useless, especially those so-called ultra-thin mobile phones, and the power of the mobile phone will be used up after playing a game or watching a video for two or three hours, which makes ** annoyed.

In particular, the screen of the mobile phone is getting bigger and bigger, and there are more and more applications, and the battery is becoming less and less used.

This makes everyone who uses smartphones feel crazy and tangled!

Li Haoyu's eyes swept over the large pile of colored stones turned into astatine elements on the ground, and he roughly estimated in his heart that there were twenty or thirty thousand such stones here, and he suddenly felt a burst of deflated in his heart. There are so many batteries for mobile phones, notebooks and other electronic products in the world today, just such a little astatine element can't meet such a big gap, in case the astatine element is exhausted, and there is no replacement, he will offend the people of the whole world!

"My dear master, don't worry about this problem, although I don't know the specific information of this technique, but the astatine element contained in such a stone should be enough to make 100 million astatine batteries, and the stones here can make two or three trillion batteries. In addition, if there are any other places on the island, this stone full of astatine can guarantee the supply of astatine batteries for at least 20 years. Even if there are no other stones of this kind on the island, the batteries made of astatine can still be recycled, and the astatine in the batteries will wear out relatively little even if they are used for a few years. At that time, the privileges of the Super Game Editor should be very high, and it should be possible to unlock new battery skills. ”

Li Haoyu finally relaxed a lot when he heard this, and asked, "What is the authority of the astatine element battery production technique?" ”

Xiao Yu thought for a while and said, "In the fourth authority, at most the fifth authority, there is the technical information of the astatine elemental battery!" ”

Li Haoyu nodded, as long as he could go back alive, no matter what the price was, he must buy this island, at least he must scavenge the stone full of astatine elements on the island.

"Li, what are you doing in a daze, I told you not to answer for a long time?" Emily stretched out her hand and shook it in front of Li Haoyu's eyes, and seeing that Li Haoyu had been in a daze, she couldn't help but pat him angrily.

Li Haoyu woke up and said, "Emily, I suddenly remembered something just now, and I thought about it too much and didn't hear you, I'm sorry." ”
