"You guys are really fateful, see if you dare to do anything in the wilderness next time. Ying Hai looked at the four people who were hanging up from the cliff, although his expression was not very good, but from his judgment, he was not injured.

Ying Hai looked at the four people for some reason, and suddenly remembered the sudden phone call, which was very professional and accurately reported the latitude and longitude of the four missing people, which made him, a rescuer, a little curious.

"By the way, there was a person who called me and told me that you are here, are you your friends?" Ying Hai looked at the four of them and asked with some curiosity, the previous phone call knew too much about the situation of the four people.

When the other three heard this, they all looked at Fang Bing, and the three of them looked ashamed, grateful, and admired, and before they came out, they swore that they were security experts and that the rescue plan was very good.

But the truth is cruel, they have no role outside, and they have become a drag oil bottle, if it weren't for Fang Bing, it would be a question of whether they could come out.

"It's my friend. Fang Bing replied with a deep groan.

"How did he know you were here?" asked Ying Hai with some curiosity, this was what he wanted to ask the most.

"It was through drones that we were found. Fang Bing pointed to the flying drone.

"Remote control, where are the others?" Ying Hai suddenly thought in his heart, he watched these two drones take off, but he didn't expect that these two drones still have such a function.

.......

After Wang Hao finished making the call, he turned on Fang Bing's live broadcast, and after seeing that Fang Bing was rescued, he didn't care anymore, anyway, Fang Bing was fine.

And the research on the portable air purifier, borneol for the time being, unless it is to add more servers, otherwise the improvement of optimization has reached the limit, which can be regarded as a temporary end, and the direction he wanted to study before can finally be studied.

The air purifier that he carries with him, there is still a certain degree of difficulty, the difficulty is how to purify the air around his body, if it is by pure adsorption, this is unrealistic.

Because people are moving, if you go to a place, you can absorb the air and have a purifying effect, so it is better to take an air purifier and bring it directly to your body.

"Get a spraying device on the top of your head?" Wang Hao pondered for a moment, and thought of a feasible plan, but shook his head for a moment, if he really got a spraying device on his head, it could only be made into a hat, although it did not affect the actual use, but the fine water mist sprayed at all times, the impact on the action, let him immediately veto it.

Wang Hao thought for a long time, and finally shook his head, and had no other clue.

"Xiaolong, bring up the previous research plan for nano-ion batteries and show me. Without thinking, Wang Hao did not hang himself on a tree, but asked Xiaolong to sort out a report on the battery and his own ideas.

Wang Hao looked at this research plan, pondered, and considered the feasibility of it, nanoion was something that he suddenly thought, which was a material that could be made into batteries.

At present, most of the mainstream batteries are supercapacitors, nickel batteries, fuel cells, and the most common lithium batteries.

These four different battery technologies have pros and cons, and the focus is not the same, such as supercapacitors, which have low power storage and cannot be installed on some new energy vehicles, because they cannot be used for a long time.

For example, nickel batteries, the full name of metal hydride nickel batteries, have high current electrical capacity and high safety, but the capacity is low and the volume is huge, which limits the application direction of nickel batteries.

The most common is the lithium battery, the voltage is the highest among the four types of batteries, the specific capacity is high, but the safety and low temperature performance is poor.

The sodium ions discovered by Wang Hao are different, the earth is rich in sodium resources, as early as the last century, it was developed, but it was replaced by lithium batteries.

The most important thing is that Wang Hao discovered the mutated sodium ions during his research, which has a capacity of about five to ten times that of the sodium ions before the mutation.

If all the mutated sodium ions are used as the material, the batteries made of sodium ions will also reach five to ten times the capacity of ordinary batteries.

The most important thing is that this mutated sodium ion is very suitable for graphite materials, which will cause structural collapse after multiple de-intercalation with graphite materials, but after the mutation, Wang Hao experienced a test and found that there was no such phenomenon.

And in other properties, it is also completely explosive lithium ions, the only thing that makes him regrettable is that the mutated sodium ions were made by him unintentionally, and it is not considered a controllable mutation for the time being.

He needs to go through many experiments, record analysis and comparison, and after turning this mutation into a controllable mutation, then this sodium ion, combined with graphite materials, to form a new battery, can be launched.

"The test equipment parts have not yet arrived, and after they arrive, we can carry out sodium ion research. Wang Hao's eyes flashed with a hint of desire, if this battery research is out, in terms of his predicted performance, it will surpass the current battery performance by more than ten times, but the volume will not be much larger.

And in terms of charging performance, the performance effect is definitely better than that of lithium batteries, but in order to achieve these, only after mastering the No. 1 sodium ion mutation method named by Wang Hao.

Originally, Wang Hao wanted to study graphite dilute batteries, but after making a discovery on sodium ions, he shifted his attention and prepared to study the batteries of sodium ions combined with graphite materials first.

If the performance is not to his liking, he will study the graphite thin battery, this is his idea.

Wang Hao was deliberating about the direction of the test after that, when suddenly the phone rang.

"Hey, Zhang Xin!!" Wang Hao glanced at it and picked it up.

"Brother, it's the National Day soon, and we're ready to come over to you. ”

Wang Hao listened to the excitement in Zhang Xin's words, and then he reacted, this is about October.

"Yes, come here. Wang Hao paused, and said again, "By the way, will my parents come over?" "No, but the four of us, and my two classmates." ”

"Okay, I'll pick you up then. ”

"Good. ”

Wang Hao hung up the phone, with a smile on his face, only if he has lost, he will cherish it more, what he said is not wrong at all.

He now values the people around him the most, and after he learned that Fang Bing was missing, he immediately used his own means to find the reason.

"Xiaolong, fundamentally mutating the characteristics of sodium ions, and conducting a tentative reverse test. After Wang Hao hung up the phone, he plunged into the research and said to the dragon brain.

There are only a few mutated sodium ions left, except for some mutated sodium ions that destroyed the tissue structure during his research, the others have been preserved, although they have destroyed a lot, but they have allowed him to study the characteristics of mutant sodium ions, and let the research characteristic data be entered into the borneol.

Combined with the sodium ions before the mutation, try to see if the mutation process can be reversed.
