A few days continue to erupt, begging for support, begging for a monthly pass!

Bin Xinwei saw that Jin Xiaoqiang's attitude was so calm, and his heart was relieved.

Then he took Jin Xiaoqiang to the inside of the experimental building, where they were just now was the hall on the first floor of the experimental building, which was the place where Binxinwei assigned tasks to the employees below every day, or made briefings, and held summary meetings.

Walk through the hall to a corridor, on the left hand side of the corridor is a large sun room, this room is about more than 150 square meters, through the large glass door at the door, you can see that there are more than a dozen experimenters dressed neatly and richly, where the experiment is being carried out, and a group of computers against the wall are constantly recording data.

And they are all gathered in front of several test benches, some are using droppers to drip liquid into the test tubes, and some are holding a few white objects, doing charging and discharging experiments......

"This is our battery cathode laboratory, and now the experimenters are testing suitable materials, Mr. Jin, you also know that since we have identified graphite as the negative electrode of the battery, we have been looking for a suitable material to make the positive electrode of the battery, but we have tested a variety of compounds, but have not found a suitable material."

Bin Xinwei took Jin Xiaoqiang to stand at the gate of the laboratory, watching the experimenters inside busy, and then introduced Jin Xiaoqiang.

"What materials did you use for your research?"

Jin Xiaoqiang asked.

"We used lithium manganese oxide and lithium cobalt oxide successively, but the results were not ideal. The working condition of lithium manganese oxide is very bad, if you use this material as the positive electrode of the battery, the first thing to face is the problem of high temperature overheating, this material is not suitable for working in the case of high temperature overheating, once the temperature exceeds a certain temperature, then he will produce problems such as high temperature structure decay, which will lead to the attenuation of the capacity of the battery, which will affect the life of the battery very much. The material of lithium cobalt oxide also has its own shortcomings, this material is used as the positive electrode of the battery, the year-on-year charging capacity will be much lower than that of lithium manganese oxide, and once it is a charging country, there will be a danger of explosion, and the most important thing is that cobalt is highly toxic This element is not suitable for the current environmental protection concept......

Binxinwei introduced their R&D progress to Jin Xiaoqiang, Jin Xiaoqiang also nodded when he heard this, lithium manganese oxide and lithium cobalt oxide, these two substances, are indeed the mainstream direction of research in the lithium battery industry in recent years, but it is indeed because of the problems they said, it has been difficult to make breakthroughs, so this has delayed the research and development of lithium batteries.

"By the way, haven't you tried any other materials?"

Jin Xiaoqiang asked Bin Xinwei again, but at this time, Bin Xinwei smiled very strangely at Jin Xiaoqiang, and then whispered to Jin Xiaoqiang.

"Mr. Jin, in fact, we have been trying a new material recently."

"Oh? Hear what it says. ”

"It's lithium iron phosphate."

As soon as Bin Xinwei said this material, Jin Xiaoqiang couldn't help but feel that he was going to be impressed by him, doesn't this guy have two brushes, this lithium iron phosphate is the mainstream material for the battery cathode used in lithium batteries in the future.

The cathode of the first lithium battery that will be launched next year is made of this material.

"Really? How did you discover this material? ”

Jin Xiaoqiang came and asked Bin Xinwei with interest, but he didn't expect Bin Xinwei to be slightly pale at this time, and hesitated for a while before saying to Jin Xiaoqiang.

"Mr. Jin, you have to keep this kind of material confidential for me, it turned out that a colleague of mine when I was working in the United States told me. We used to work in the same laboratory, and then I resigned and returned to China, and he went to Southwest Nano to continue to engage in lithium battery research. ”…,

Looking at Bin Xinwei's somewhat embarrassed expression, Jin Xiaoqiang couldn't help but smile in his heart, I'm afraid that this former colleague of Bin Xinwei is a woman, right? And maybe the relationship with him is quite unusual, otherwise who would be able to tell outsiders such a confidential thing?

Hehe, I don't see that this bin Xinwei will still make a beautiful man, ha?

But looking at his expression, he obviously didn't want people to know about it, so he simply didn't block him, and pretended not to know.

"Oh? That's great, haha, Engineer Bing, you have to maintain your relationship with him, try to get something out of his mouth, and if he wants to, or if he gets tired of doing something in Nano, let him come over and help, I'm here to give him better conditions at any time. ”

Jin Xiaoqiang said to Bin Xinwei with a smile.

"Yes, good......

The expression on Bin Xinwei's face was even more embarrassed.

"By the way, since you have used lithium iron phosphate as the main cathode research object, have you made any breakthroughs?" Jin Xiaoqiang was very concerned about the letter of the guest.

"Well, not yet, at present, I have arranged a large number of manpower to conduct experiments in this direction, and strive to overcome this problem as soon as possible. I heard that Nano has made a certain breakthrough, which means that this direction is correct, and we must firmly follow this path. And compared with lithium manganese oxide and lithium cobalt oxide, this lithium iron phosphate as the cathode material of the battery, the advantages are too many, and its cost is much lower than that of lithium manganese oxide and lithium cobalt oxide, because there is no need to use a large amount of manganese and cobalt

Such a precious metal element is non-toxic, the safety is better than which two materials, and the life is higher than which two materials, so this material is definitely very suitable as a material for the cathode of lithium batteries. ”

Bin Xinwei introduced Jin Xiaoqiang again.

"So what's your problem?"

Jin Xiaoqiang asked Bin Xin Wei again.

"In terms of stability and electronic transmission, there is still a lot of difference in low-temperature performance."

Bin Xinwei said to Jin Xiaoqiang.

"Then have you taken into account the addition of lithium iron hydrochloride, manganese and cobalt?"

Jin Xiaoqiang seemed to mention it very casually, but after Bin Xinwei heard such a sentence, he immediately fell into a sluggish state.

Looking at the stupid appearance of the person in front of him, Jin Xiaoqiang felt a little uncertain, so he quietly pushed Bin Xinwei.

"Engineer Bing? Engineer Bing? ”

"Huh? Yes? Oh, Mr. Jin, you are really a genius, such a simple idea, why didn't we think of it? We have done so many experiments before, all in the state of lithium iron phosphate, and working conditions, we didn't expect to add manganese and cobalt to it, but these two elements are to ensure that the lithium battery works well at low temperatures, and strengthen the passability and electronic vitality of the important elements! Mr. Jin, no wonder others say that you are a genius, I am really convinced......

Bin Xinwei felt a little crazy at this time, it was indeed a problem that had been bothering him for several months, and at this time, Jin Xiaoqiang unintentionally solved it with a sentence, how could he not be excited?

If you change to someone who doesn't know how to do it, you will definitely think that Jin Xiaoqiang's words are very amateurish, but it is this amateurish attitude, this very amateurish idea, but it is the key to solving the battery cathode problem that plagues Binxin Micro.

The reason why people chose lithium manganese oxide and lithium cobalt oxide as the research object of lithium battery cathode is precisely because they can increase the ability of electrons to pass through, as well as ensure the characteristics of low temperature operation of the battery, although they have many shortcomings, but for so many years people have used them as the best material for lithium battery cathode research, it is precisely because of their previous advantages. …,

Later, lithium iron phosphate was chosen because people were unable to overcome their shortcomings, so they retreated to other materials.

However, this new material lithium iron phosphate is not omnipotent, compared with lithium manganese oxide and lithium cobalt oxide, it has obvious advantages and disadvantages.

In the lithium batteries of later generations, it was the addition of manganese and cobalt elements to lithium iron phosphate that overcame the shortcomings of only lithium iron phosphate.

And Jin Xiaoqiang, as a person who has crossed through rebirth, of course, understands this very clearly, of course, he only knows how people do it, as for how much manganese and cobalt are configured in lithium iron phosphate, he is definitely not clear.

As for what the next counterweight ratio is, it can only be studied by Bin Xinwei and them, and he Jin Xiaoqiang is only responsible for technical guidance this time.

"This idea is great, Mr. Jin, now the cathode material of our lithium battery is finally down, the material of the negative electrode and the positive electrode have been found, and our battery may soon be formed."

At this time, Bin Xinwei has long been able to continue to maintain a calm attitude, and it is not too much to say that he is ecstatic, as a scientist who has been engaged in lithium battery technology research for many years, he is well aware of the importance of Jin Xiaoqiang's proposal.

This proposal will definitely be a big breakthrough in the research of lithium batteries.

"Well, hehe, don't worry, first add the formula ratio of manganese and cobalt to this lithium iron phosphate, study it, and then make the first generation of batteries, let's use it first, and then continue the next step of research."

Jin Xiaoqiang smiled and said to Bin Xinwei that with such a first-generation lithium battery, then his first-generation hybrid will not be far from being born.

"Yes, yes, I'm going to arrange for manpower and start the experiment right away......"

Bin Xinwei couldn't take care of Jin Xiaoqiang at this time, and he was about to go to the laboratory to do experiments, but how could Jin Xiaoqiang agree, he still had some ideas for battery anodes to provide to Bin Xinwei...... ）
