When a person and a cat were still stunned, there was a situation on the top of their heads.

"Bang"

"Bang"

With two sounds, two large pieces of iron fell from the sky, one smashed one meter on the left hand side of Gao, and the other smashed half a meter in front of the little flower cat's head.

"Meow!"

Xiaohua fried her hair directly: Hold the grass, it wasn't enough to up last time, and you have to smash me this time?

A flutter, jumping to the top and a cat's paw massage.

The corners of Gao Gao's mouth twitched, and he looked at the two piles of broken copper and iron speechlessly, and scolded Chitose in his heart:

"Did you know they were going to have a problem? Why didn't you tell me earlier? Don't you know that Xiaohua and I were almost smashed by these two idiots?"

"Sir, I alerted you when they had problems. ”

Chitose slowly slipped out of the back room, the ambient lights had gone out, and the alarm had shut up.

Fortunately, there was not much movement just now, and the sea breeze was also whirring, and Gao breathed a sigh of relief, facing Chitose is a brain meltdown.

Xiaohua was ravaged high, and she was still angry, and it was also a ravage to jump on Chitose's head.

"Squeak", he couldn't get his hand this time, and after a while, the drone above Chitose's head was scratched by him with a big hole.

"Mr. Hua, Mr. Hua, stop...... Stop ......"

Suddenly, Chitose was silent.

"Meow. "Bastard, let you scare me.

After Xiaohua let out a sigh, she jumped to the courtyard wall with the steps that her six relatives did not recognize, and began to watch the sky at night.

"Sir, Mr. Hana scratched my circuit......" Chitose wanted to cry without tears.

Feeling Chitose's information, Gao Gao was also big for a while, "Let's not talk about this first, what's going on with the two of them?"

Pointing to the two piles of broken copper and iron on the ground, Gao Gao directly told the two guys to shut up.

It's noisy, it's not annoying.

"As with the explosion in the last experiment, the lithium ions were too active and the temperature was too high, and the explosion occurred. ”

"Overactive?"

Gao frowned, "Something is wrong, we have diluted the proportion of SAR, and it is already extremely small." ”

"Send me a copy of the data log. ”

After receiving Chitose's observation logs, he compared them one by one.

From yesterday until the eve of the explosion, he read all the logs.

The problem has been found.

Everything is normal during the charging of the lithium battery, and the activity of the lithium ions is within a controllable range.

At the time of discharge, the activity of lithium ions is also in the acceptable range.

As of noon today, the activity of lithium ions can be said to be on the verge of anomalies, but it is also below the upper limit of their data model, which is acceptable.

Just now, the activity of lithium ions suddenly increased geometrically, completely breaking through the upper limit of the data model.

"The problem should be with the anode material, which is a graphite material mixed with SAR. ”

After digging through the two piles of broken copper and iron for a while, Gao Gao finally found the two batteries.

The bones have long been blown up, but the negative electrode material can still be found.

"Let's go and test this material and see what the hell is going on. ”

......

Looking at the test report issued by Chitose, Gao Gao was overjoyed.

"Does it mean that SAR will have an assimilating effect on graphite?"

"That's right, theoretically it can only be explained that there is no change in the SAR itself, but the molecular structure of the graphite molecule that is close to it seems to have been recast, and some graphite molecules are no longer graphite molecules at all, and the molecular structure is gradually moving closer to the SAR structure. ”

While speaking, Chitose also synchronized the images sorted out in the instrument to Gao Gao.

Indeed, the molecular structure of those graphites close to the SAR has been recast from hexagonal crystals to near-decagonal crystals, and the closest to the SAR has been assimilated to dodecagonal crystals.

Gao Gao does not think that this is a fluke.

First of all, the second and third children crashed at the same time;

He had already modified three SAR lithium batteries, but the eldest Chitose did not fly up because he was steady.

The second and third children flew for two days, and all of them had such a thing, and the accident rate exceeded 60...... , by no means a coincidence.

Secondly, the battery variable in the UAV is only a new added ingredient, SAR;

Whether it is the reactant or the encapsulation process, it is the internal operation process of DJI, and there will be no deviation in theory.

If it's because of the battery itself, won't there be more drone accidents?

Again, the data log of this accident can be said to be exactly the same as yesterday's explosion log;

All of this is caused by the overactivity of lithium ions.

The fundamental factor causing the overactivity of lithium ions is SAR.

To sum up, Gao Gao has a new inference:

SAR changes the molecular makeup of surrounding elements!

In the following time, Gao Gao had an in-depth discussion and experiment with Chitose on the above questions.

In three days, they basically solved all the above problems, and also successfully mass-produced 1000g of new graphite: NSG.

The production process is very simple, put the SAR essence and graphite into the arc box, and turn on the daily voltage of 220V.

Keeping the voltage constant and the current stable, after 10 hours, the graphite becomes NSG.

Since it is made at 220V, NSG will remain stable inside the drone battery and will not assimilate other graphites.

It cannot be said that it cannot cause assimilation, it should be said that the assimilation effect will not be so obvious.

For example, metal A is at a temperature of 100°C, and heat transfer to metal B with poor thermal conductivity at 50°C.

The temperature of metal B is definitely between 50 and 100°.

In addition, metal B is used to transfer heat to metal C, which has lower thermal conductivity than metal B, at a temperature of 20°C.

The temperature of metal C should be between 20-50°.

In the same way, under the upper voltage limit of the drone battery, even if there is some graphite, it will still be assimilated, and basically it will not damage the stability of the lithium battery, which will also solve the hidden danger of explosion again.

Similarly, because the performance of NSG is much higher than that of graphite, and at the same time much lower than that of SAR, the performance of their newly made lithium batteries has also deteriorated:

Endurance can only be increased by between 102% and 123%, explosive power can only be increased by 113% and 131%, and performance is reduced by more than two-thirds......

"That's the difference between genuine and pirated. ”

For such a result, they can only accept it.

In fact, it's already very good to think about it, just changing the anode material can double the performance of the battery.

If the cathode material is also replaced, the reactants are replaced again?

Wouldn't the performance of the battery increase geometrically, and the performance could be improved by about ten times?

......

While they were urgently promoting NSG assimilation, a discussion meeting was also going on in a laboratory at Kyokwa University in Kyoto.

"Xiao Xu, the tissues you brought back, we have analyzed them, and they are too different from the hair you brought last time. ”

Lin Lao was still holding the big water cup, and his disappointed tone was overflowing.

It's too much of a difference, and it's already as euphemistic as he can say.

The truth is, worlds of difference.

If that hair was a tightrope, then the tissue that I brought back this time was a piece of paper.

"Lin Lao, isn't there a little discovery? Someone has extracted or developed ROG from these tissues. ”

Xu Qing still didn't give up, she didn't completely trust what Gao Gao said, but tried to comfort herself: He can develop it, why can't we?

After spending so much effort and failing to achieve anything in the end, the blow to morale is very serious.

"ROG is the new drug from the Health Bureau?"

"Yes, I met the man, and although he didn't say it directly, it probably meant something like this. ”

Lin Lao nodded and took a sip of tea, "It's not that I haven't found it, it's true that some new molecular compositions have been discovered, but the effect of ROG should be inconsistent." ”

"You mean, he lied to us?"

Xu Qing's eyebrows were upside down, if that was the case, she would definitely not let go of that kid.

"Not necessarily, it stands to reason that the strength and recovery ability of the body cells of such a giant creature must be much stronger than other creatures, otherwise, it is simply not enough to support them to survive for so long, it may be that our hardware is insufficient, or there is a problem with the research direction. ”

At this time, Lin Lao also fell into self-doubt.

He didn't think there was any other place with more complete and advanced instruments than he had here.

So the problem is the direction, but where is the direction?

"Xiao Xu, you can help me get a batch of ROG original medicine, I can use it. ”

"Don't worry, Lin Lao, I promise to complete the task. ”

......

"Ding Dong" WeChat message, Lao Wan's.

Lao Wan, this female tyrant hasn't been in touch for a long time.

"What have you been doing lately, you've been grounded at home again?"

"No, I'm doing research. ”

In front of Lao Wan, Gao Gao is very relaxed, maybe it is separated by an Internet world?

"Scientific research, a chess anchor engaged in scientific research, don't tease me, play two games of chess with me. ”

Scratching his head, Gao Gao didn't know whether to refuse, continue his scientific research, or put down the work at hand and play a few games with her.

After looking at the three brothers who continued to fly overhead, he decided to give himself a vacation.

"Okay, wait for me a moment. ”

He had to move the computer out of the back room and surf the Internet in the sun, which would be more comfortable, while still being able to keep an eye on the three little ones.

When he was about to turn off the screen of his phone, a flash of inspiration flashed in his mind:

"I'm such a little genius, why didn't I think of it?"
