Chapter 59 Lead-acid batteries
The next day, Jiang Fan had breakfast and came to Long Lao's laboratory.
After a while, Long Lao also came, and after a simple communication with a few people, he left in a hurry!
After Long Lao left, Xia Xiaoyu said to Jiang Fan!
"Jiang Fan, you give advice to Academician Long, let him rest more, don't be so tired, after all, they are all old people in their sixties, and their health is important."
"Okay, by the way, senior sister, why don't you tell the teacher directly!" Jiang Fan asked suspiciously!
"I don't dare, Old Long's temper is too hot!"
Before, Xia Xiaoyu said something to Long Lao that had nothing to do with the experiment, and was scolded by Long Lao for splitting his head and covering his face!
"Teacher, he looks very kind." Jiang Fan said!
"Hey, you are different from us, you are a student of Long Lao, your identity is different from us, as the saying goes, tiger poison does not eat children!"
"Okay!"
Jiang Fan responded, looking at Xia Xiaoyu's heart palpitations, and wondered in his heart, is Long Lao so scary?
"You must be careful about this matter, once when I saw Academician Long doing an experiment, he squatted on the ground with his abdomen covered and slowed down for more than ten minutes......
Xia Xiaoyu was actually most afraid of what would happen to Long Lao's body, if this was the case, it would probably be difficult for their research room to continue!
In her junior year, she worked as an assistant to an old professor at Long University of Science and Technology, but it was because of the professor's health that the research in the laboratory was finally stopped.
Fortunately, the old professor directly transferred her to Long Lao's side, but the other students were not so lucky.
As a student, it is not easy to find a research room to do research!
Although there are many teachers who do some scientific research projects and are willing to bring their own students, how can there be so many projects with more than 10,000 students in the whole school?
Xia Xiaoyu saw Jiang Fan agree, and after repeatedly explaining, he put his mind at ease!
Jiang Fan knows very well that as a scientific researcher, behind the great achievements are all earned by working day and night.
Almost all scientific researchers will have problems with their bodies to some extent!
Then several people entered the working state.
Their R&D tasks now 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 should also be developed with the data of the energy system, otherwise the mecha arm you designed can grab 1000 kg of heavy objects, but the power of the energy is not up to it!
When the morning was almost over, Jiang Fan called them over!
"Junior brother, is there something wrong?" Xu Guangyuan asked!
"Senior, I made a summary of battery energy yesterday," he said.
"Summary, I'll take a look at the summary made by the junior first, hehe......"
After Xia Xiaoyu finished speaking, he snatched the information in Jiang Fan's hand and looked at it.
Jiang Fan didn't pay attention to it so much, he found that the parallel world Earth was much higher than the technology on Blue Star through his understanding of Blue Star battery materials yesterday!
At present, Bluestar'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 Guangyuan saw how Jiang Fan was self-motivated, and decided to listen to Jiang Fan and give him some guidance by the way.
"Senior Brother Jiang Fan, can you tell me about what you have put together?"
Jiang Fan nodded and said to the three of them.
"Mecha energy generally has the following needs, one is battery life, the other is output power, three battery life ......"
"At present, the energy source of the mecha we are studying is mainly lead-acid batteries, which have 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 500 times, and the endurance is poor, the power is insufficient, and its weight is ......"
Xu Guangyuan nodded, agreeing with Jiang Fan's summary. The analysis was on point, and it pointed out the challenges they needed to overcome.
At present, their main research focus is how to improve the comprehensive performance of lead-acid batteries.
Jiang Fan continued!
"So, I feel like we need to change the direction of our research!"
"Change direction?"
Xia Xiaoyu put down Jiang Fan's paper version of the 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 battery with sulfuric acid solution......"
"His chemical reaction PbO2 + 2H2SO4 + Pb ---> PbSO4 + 2H2O + PbSO4 (Discharge Reaction) (Lead Dioxide) (Sulfuric Acid) (Spongy Lead) The valency of Pb in PbO2 decreases by ......"
"This kind of battery structure, the performance is destined to be very low, there is no need for a little in-depth exploration, it will only be a waste of time!"
After Jiang Fan finished speaking, the three of them looked at each other!
Xu Guangyuan's impression of Jiang Fan was much worse in an instant.
The content they are studying now is the general direction given by Elder Long.
Jiang Fan's direct denial of their research was a waste of time, which was tantamount to denying Long Lao.
If Elder Long knew, I really didn't know how he would feel about him as an apprentice!
"Jiang Fan, you must know that the lead-acid battery is the best battery in Bluestar, and the technology is very mature.
I believe that in a short time, there will be a breakthrough in the lead-acid battery in our laboratory! ”
Xia Xiaoyu was the first to stand up and say!
"Senior brother, you are diligent and studious, and we all support you. But research isn't what you think! ”
"Yes, fortunately, Elder Long is not here, if he wants the old man to hear it, even if you are his student, it will inevitably be a batch!"
The three of them were stunned at Jiang Fan.
They all have the same opinion about Jiang Fan now, 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, and a wrong direction is destined to fail to make a major breakthrough!"
Xu Guangyuan saw that Jiang Fan was obsessed, and his face was a little unhappy.
They are all juniors and seniors this year, and today they were actually lectured by a freshman. So he said in a somewhat mocking tone.
"Jiang Fan, you said that our research on lead-acid batteries is a waste of time, so you tell us a correct research direction!"
"Lithium iron phosphate power battery!"
"Lithium iron phosphate power battery?"
The three of them were surprised, it was the first time they had heard of batteries of this material!
"The performance of lithium iron phosphate power battery is more than 3 times that of lead-acid battery......
The cycle life reaches more than 2000 times, and the thermal peak can be 350°C-500°C. Wide operating temperature range (-20C--+75C)......"
Jiang Fan began to introduce to them the performance of lithium iron phosphate power batteries. They couldn't believe it!
You know, the lead-acid battery they studied can only increase the performance prediction by up to 30%!
