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

After a while, Old 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 give me advice to Academician Long, so that he can rest more and don't 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, Old Long has a hot temper!"

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

"Teacher looks very kind," Jiang Fan said!

"Hey, you are different from us. You are a student of Mr. Long, and your identity is different from us. As the saying goes, "A tiger is poisonous and doesn't eat any more people!"

"All right!"

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

"You must be concerned about this matter. Once, when I saw Academician Long doing an experiment, he squatted on the ground with his abdomen and slugged on the ground for more than ten minutes..."

Xia Xiaoyu is actually most afraid of what kind of situation does Old Long’s body appear. If this is the case, it will probably be difficult for their laboratory to continue!

When she was in her junior year, she followed an old professor at Longhai University as an assistant. It was because of the professor's physical reasons that the laboratory research was forced to stop.

Fortunately, the old professor directly transferred her to Old Long's side, but the other students were not so lucky.

As a student, it is very difficult to find a laboratory for research!

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

Seeing Jiang Fan agreeing and repeated explanations, Xia Xiaoyu felt relieved!

Jiang Fan knew very well that as a scientific researcher, the great achievements behind the great achievements were obtained by life-long research.

Almost all scientific researchers will have more or less problems in their bodies!

Then a few people entered the working state.

Their current R&D tasks are very heavy. The mecha's energy system is the core system of the entire mecha.

All functions are driven by the energy system.

The design of other mecha systems must also be developed in conjunction with the energy system data, otherwise the mecha arm you designed can grab 1,000 kilograms of heavy objects, and the power of the source may not reach versatility!

When the morning was almost over, Jiang Fan called them over!

"Senior brother, is there anything wrong?" Xu Guangyuan asked!

"Senior, I made a summary of battery energy yesterday," said the

"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 and started reading it.

Jiang Fan ignored so much. Through his understanding of Blue Star battery materials yesterday, he found that the parallel world Earth is much higher than the technology on Blue Star!

Currently, Blue Star’s mainstream batteries are also lead-acid batteries.

On the earth, lithium cobalt oxide 18650 batteries, nickel-hydrogen batteries, lithium iron phosphate batteries, ternary lithium batteries, etc. have been studied, and their performance is more than 3 times higher than lead-acid batteries!

Seeing how Jiang Fan was motivated, Xu Guangyuan decided to listen to Jiang Fan and give him some guidance.

"Senior Brother Jiang Fan, can you tell me what you have summarized?"

Jiang Fan nodded and said to the three of them.

"Mecha energy generally has the following requirements: one is battery life, the other is output power, and three battery life..."

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

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

Xu Guangyuan nodded, agreeing with Jiang Fan's summary. The analysis was very well done and pointed out the difficulties they needed to overcome.

Their main research focus is how to improve the comprehensive performance of lead-acid batteries.

Jiang Fan continued!

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

“Change direction?”

Xia Xiaoyu put down Jiang Fan’s paper version to summarize and said in surprise!

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

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

"His chemical reaction pbo22h2so4pb----pbso42h2opbso4 (discharge reaction) (lead dioxide) (sulfuric acid) (sponge-like lead) The compound valence of pb in pbo2 is reduced..."

"The performance of this battery structure is destined to be very low. Without any need for in-depth exploration, it will only waste time!"

After Jiang Fan finished speaking, the three of them looked at each other!

Xu Guangyuan instantly had a much worse impression of Jiang Fan.

The content they are now researching is the general direction given by Mr. Long.

Jiang Fan directly denies their research a waste of time, which is equivalent to denying Mr. Long.

If Old Long knew, 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-performance batteries, and their technology is very mature.

I believe that it will be possible to make a breakthrough in the lead-acid battery in our laboratory in no time to use it!”

Xia Xiaoyu was the first to stand out and said!

"Senior brother, you are diligent and studious, and we are all supportive. But scientific research is not what you think of!"

"Yes, fortunately, Old Long is not here. If he wants to hear it, even if you and his students are not allowed to criticize him!"

The three of them scolded Jiang Fan.

They now have the same view on Jiang Fan, that is, they are young and frivolous!

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

"For scientific researchers, the research direction is very important. A wrong direction is destined to be unable to make a major breakthrough!"

Xu Guangyuan saw Jiang Fan stubbornly and had a little displeasure on his face.

They are both junior and seniors this year, but today they were preached by a freshman. So they said in a sarcastic tone.

"Jiang Fan, you said that it is a waste of time to study lead-acid batteries, so tell us the correct research direction!"

"Lithium iron phosphate power battery!"

"Lithium iron phosphate power battery?"

The three of them said in surprise that this was the first time they heard about batteries with 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 2000 times, and the thermal peak can be 350c-500c. 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 so disbelief!
Chapter completed!
