The next day, after Jiang Fan had breakfast, he came to Mr. Long's laboratory.

After a while, Mr. Long also came. After a brief communication with a few people, he left in a hurry!

After Mr. Long left, Xia Xiaoyu said to Jiang Fan!

"Jiang Fan, please advise Academician Long and ask him to rest more and not be so tired. After all, he is an old man in his sixties and his health is important."

"Okay, by the way, senior sister, why don't you tell the teacher directly!" Jiang Fan asked in confusion!

"I don't dare, Mr. Long's temper is too hot!"

Before, Xia Xiaoyu said something to Elder Long that had nothing to do with the experiment, and was scolded by Elder Long!

"Teacher, he looks very kind," Jiang Fan said!

"Hey, you are different from us. You are Mr. Long's student, and your status is different from ours. As the saying goes, a tiger's poison cannot eat its seeds!"

"All right!"

Jiang Fan responded, looking at Xia Xiaoyu with lingering fear, and wondered in his heart, is Mr. Long that scary?

"You must pay attention to this matter. Once when I saw Academician Long doing an experiment, he squatted on the ground with his belly covered and waited for more than ten minutes..."

Xia Xiaoyu is actually most afraid of something happening to Mr. Long's body. If this happens, it may be difficult for their research laboratory to continue!

In her junior year, she worked as an assistant with an old professor at Longke University. Because of the professor's health, the research in the laboratory was forced to stop.

Fortunately, the old professor directly transferred her to Mr. Long, but other students were not so lucky.

As a student, it is not easy to find a research laboratory to do research!

Although there are many teachers who are doing some scientific research projects and are willing to take their students with them, how can there be so many projects in the school with more than 10,000 students?

Xia Xiaoyu felt relieved after seeing Jiang Fan agree and explain again and again!

Jiang Fan knew very well that as a scientific researcher, behind his great achievements was the result of hard work day and night.

Almost all scientific researchers have physical problems to some extent!

Then several people got into work mode.

Their current research and development tasks are very heavy. The energy system of the mecha is the core system of the entire mecha.

All functions are driven by the energy system.

The design of other systems of the mecha must also be developed in conjunction with the data of the energy system. Otherwise, if the mecha arm you design can pick up 1,000 kilograms of weight, the power of the source may not reach that level and it will still be versatile!

When the morning was about to end, Jiang Fan called them over!

"Junior, what's the matter?" Xu Guangyuan asked!

"Senior, I made a summary of battery energy yesterday,".

"Summary, let me take a look at the summary made by my junior first, hehe..."

After Xia Xiaoyu finished speaking, she snatched the information from Jiang Fan's hand and started reading it.

Jiang Fan didn't pay much attention to it. Through yesterday's understanding of Blue Star's battery materials, he discovered that the technology of the parallel world Earth is much higher than that of Blue Star!

At present, Blue Star’s mainstream batteries are still lead-acid batteries.

Lithium cobalt oxide 18650 batteries, nickel metal hydride batteries, lithium iron phosphate batteries, ternary lithium batteries, etc. have been developed on the earth, and their performance is more than 3 times higher than that of lead-acid batteries!

Xu Guang had a vision of why Jiang Fan was so ambitious, so he decided to listen to what Jiang Fan had to say and give him some guidance.

"Jiang Fan, can you tell me what you have compiled?"

Jiang Fan nodded and said to the three of them.

"Mecha energy generally has the following needs, one is endurance, the other is output power, and the third is battery life..."

"The mecha energy we are currently researching is mainly lead-acid batteries. This kind of battery has stable performance and mature technology..."

"But as a mecha energy source, I feel that it is far from enough. The cycle life of the lead-acid battery is about 300 times, and the maximum is only 500 times. It also has poor endurance, insufficient power, and its weight..."

Xu Guangyuan nodded and agreed very much with Jiang Fan's summary. The analysis was very accurate and pointed out the problems they needed to overcome.

At present, their main research focus is how to improve the overall performance of lead-acid batteries.

Jiang Fan continued!

"So, I feel that the direction of our research needs to change!"

"Change direction?"

Xia Xiaoyu put down Jiang Fan's paper summary and said in surprise!

"Yes!" Jiang Fan glanced at her and said firmly!

"Lead-acid batteries are mainly made of lead and its oxides, and the electrolyte is a sulfuric acid solution..."

"His chemical reaction PbO2 + 2H2SO4 + Pb ---> PbSO4 + 2H2O + PbSO4 (discharge reaction) (lead dioxide) (sulfuric acid) (spongy lead) The valence of Pb in PbO2 decreases..."

"The performance of this kind of battery structure is destined to be very low. There is no need to delve into it in depth. It will only be a waste of time!"

When Jiang Fan finished speaking, the three of them looked at each other in shock!

Xu Guangyuan's impression of Jiang Fan suddenly changed a lot.

What they are currently researching is the general direction given by Mr. Long.

Jiang Fan directly denied that their research was a waste of time, which was equivalent to denying Mr. Long.

If Mr. Long knew about it, I really don’t know what he would think of his apprentice!

"Jiang Fan, you have to know that lead-acid batteries are Blue Star's best-performing batteries, and the technology is very mature.

I believe that it will not take long before our research laboratory will have a breakthrough in lead-acid batteries!"

Xia Xiaoyu was the first to stand up and say!

"Junior, you are diligent and studious, and we all support you. But scientific research is not what you think!"

"Yes, fortunately Mr. Long is not here. If he were to hear it, even you and his students would be punished!"

The three of them scolded Jiang Fan.

They all have the same opinion about Jiang Fan now, that he is young and frivolous!

Jiang Fan waited for them to finish speaking and then continued to speak slowly!

"For scientific researchers, the research direction is very important. A wrong direction is destined to prevent major breakthroughs!"

Xu Guangyuan saw that Jiang Fan was stubborn and had some displeasure on his face.

They are all juniors and seniors this year, and today they were lectured by a freshman. So he said with a somewhat mocking tone.

"Jiang Fan, you said that our research on lead-acid batteries is a waste of time, then tell us a correct research direction!"

"Lithium iron phosphate power battery!"

"Lithium iron phosphate power battery?"

The three of them were surprised that this was the first time they had heard of a battery made of this material!

"The performance of lithium iron phosphate power batteries is more than three times that of lead-acid batteries...

The cycle life reaches more than 2,000 times, and the thermal peak can be 350℃-500℃. The operating temperature range is wide (-20C--+75C)..."

Jiang Fan began to introduce to them the performance of lithium iron phosphate power batteries. They were in disbelief!
Chapter completed!
