reborn industrial empire

"Mr. Jin, you are here. Haha, you have been back for so many days and you haven't come to see me. If I didn't call you, wouldn't you even remember our laboratory?"

Seeing Jin Xiaoqiang walking into the laboratory building, Bin Xinwei, who had been looking forward to it for a long time, immediately came up to him and joked with Jin Xiaoqiang with a smile.

"I'm so busy during this period. I'm really sorry. In fact, I've wanted to come over and have a look."

Jin Xiaoqiang explained that in fact, since he went abroad, he has been paying attention to the progress of the battery research institute. On average, he has a video conference with Binxin WeChat every day to learn about their latest lithium battery research and development status.

He also gave them some suggestions and guidance based on his understanding of later generations of lithium batteries. After returning to China, he was really a little embarrassed that he had not been able to come to the laboratory to have a look because of many trivial matters.

"Haha, it's nothing, it's nothing. I know that you, Mr. Jin, are busy with things. I called you here this time because I want to give you a face-to-face introduction to our lithium battery research and development status."

Binxin smiled and said to Jin Xiaoqiang. It could be seen from his expression that he had been doing very well recently. He must have made a breakthrough in the lithium battery research project that he had been following up.

"What? Has our lithium battery research made any progress?"

Jin Xiaoqiang didn't play any tricks and asked straight to the point. This was actually the question he was most concerned about.

"Haha, yes, we have finally developed the lithium iron phosphate battery that Mr. Jin told you before. And by the way, we have also developed the management system for this lithium iron phosphate battery."

Bin Xinwei said to Jin Xiaoqiang with a proud face.

"Really? This is great. Engineer Bin, you have helped our company solve a big problem. Haha, don't worry, I will definitely celebrate your success at the celebration party at the end of this year. Then your battery research

Everyone gets a big red envelope."

When he heard the news, Jin Xiaoqiang almost jumped up for joy, but now he was actually dancing for joy.

"Haha, okay then, let's go, Mr. Jin, I'll take you to see our samples."

Binxinwei is a scientific researcher with a straightforward personality. As he said this, he took Jin Xiaoqiang to see samples of their lithium iron phosphate batteries.

Following Binxinwei, they walked through several corridors, went up to the second floor, and then put on some protective clothing before they entered a laboratory, which also carried out high-standard dust-free sterilization.

Processed. Through the glass of the laboratory, Jin Xiaoqiang saw the lithium iron phosphate battery being tested on the bench inside the laboratory.

In fact, when it comes to lithium batteries, the concept of this thing has been around for a long time, almost more than a hundred years ago. As early as the 19th century, many scientists discovered that lithium ions are actually very suitable for storage batteries.

material.

But unfortunately, lithium ions are too active. Let alone making batteries, they will burn and explode when exposed to air and combined with oxygen. This is due to the instability of lithium ions and the technology at that time.

Due to the restrictions of conditions, people's research on this element has slowed down.

Later, in the 1970s, due to the oil crisis, people came up with the theory of lithium batteries and conducted continuous research. By the 1990s, the Japanese had achieved certain results in the field of lithium batteries.

Achievements, small lithium batteries have been manufactured and are continuously used in digital cameras, laptops, and mobile phones. However, they have not been widely promoted. Firstly, the cost is too high, and secondly, because of their

for the sake of stability.

In recent years, major commercial companies around the world have increased their investment in the research and development of lithium batteries. Their main research direction is to find more suitable carriers for the positive and negative electrodes of lithium batteries.

During this period, many kinds of lithium batteries were born, such as lithium manganese oxide batteries, lithium cobalt oxide batteries, etc., but their performance was not satisfactory, and the negative electrode material manufacturers have not been able to make any breakthroughs, so lithium

The research and development of batteries has also been at a standstill. Until recently, black&decker launched the latest electrician's tool kit. Many workpieces in it use lithium batteries as power sources, and their new lithium iron phosphate batteries can also be regarded as lithium-ion.

Battery research points to new directions.

On the Huayang Power side, almost last year, Jin Xiaoqiang pointed out the research and development direction of lithium iron phosphate as the cathode of lithium batteries to Binxin WeChat. After more than a year of experiments, Binxin WeChat finally

We have come up with the latest model of lithium battery that is most suitable for hybrid vehicles.

"Mr. Jin, when you told me last year that lithium iron phosphate was used as the cathode material of the battery, I didn't quite believe it, because before that, our domestic research direction of lithium batteries was to follow the international trend, and generally we were researching and using it.

Lithium manganate is used as lithium battery

Cathode material. Later, I used two materials as the cathode material of the battery. After doing a comparison, I found that you were right. Compared with lithium manganate, the energy capacity density of lithium manganate is 100-115mah/g.

Lithium iron phosphate is 130

-140mah/g. In terms of charging times, lithium manganate batteries can be charged more than 500 times, while lithium iron phosphate batteries can be charged more than 1500 times. The difference in operating temperature is even greater. The operating temperature of lithium manganate batteries is 0

to 50°, then

The other is -40 to 70°. Judging from these main indicators, this lithium iron phosphate battery can be said to be completely better than the lithium manganese oxide battery, and in the current world, it seems that this lithium iron phosphate is the most

It is suitable as a material for the cathode of lithium batteries."

Binxin looked at the lithium battery pack that was undergoing discharge tests on the bench in the laboratory, and then said to Jin Xiaoqiang. Jin Xiaoqiang nodded frequently after hearing this, nonsense, otherwise I would recommend lithium iron phosphate as the positive electrode of the battery.

?

These materials were all developed after repeated efforts by major companies in later generations.

"You told me a few days ago that you want to test the use of this lithium battery on large buses to see how heavy and efficient it is. Li Qiming and I also found a few buses and did a simple experiment. In these few days

We use this new type of lithium battery on the bus, and the Japanese are currently using it on the Prius

The above nickel-metal hydride battery is compared. If a nickel-metal hydride battery is installed on a bus to make a hybrid vehicle, the driving range of this type of vehicle is short, and because the nickel-metal hydride battery pack itself weighs more than 600 kilograms, it consumes

Quite a lot of fuel energy, calculated overall, if the entire vehicle is not re-engineered

In terms of layout design, a hybrid bus using nickel-metal hydride batteries is completely useless. When using our lithium batteries, the situation is completely different. The total weight of our lithium battery pack is less than 200 kilograms.

Even less than one-third of a nickel-metal hydride battery, and the battery is energy-dense

It has a high temperature and a long discharge time, so the bus has a long endurance even when it is fully loaded. In the speed range of 0-40 kilometers per hour, our lithium battery pack alone can travel up to 60 kilometers.

The longest distance, and then enter hybrid mode to charge the battery pack..."

As soon as Binxin WeChat started talking about the lithium iron phosphate battery he recently developed, he started talking non-stop. This lithium battery technology can be said to be his lifelong pride. Finally, our Chinese researchers have made great progress in certain technologies.

The field can reach the forefront of foreign scientists.

We must know that before this, we have been following the foreigners, and now it is finally their turn to follow ours.

Jin Xiaoqiang was very happy after hearing Binxin WeChat's introduction. When he had talks with the Du family and Liu Yonghao in the capital, both parties had hinted to him that they hoped he could travel on buses or large public transportation vehicles.

Go up, make a breakthrough as soon as possible, and then we can be proud of our Chinese people at the Beijing Olympics.

At that time, of course Jin Xiaoqiang promised that there would be no problem, but in fact, his heart was still hanging in the air because he had always asked Binxinwei to develop lithium batteries, but he asked Binxinwei to research lithium batteries.

Batteries are mostly used in small cars, and they are not suitable for use in large public transportation systems.

Unexpectedly, Binxin WeChat fulfilled its mission and produced this large lithium battery pack so quickly. Fortunately, fortunately, it finally helped the uncle of the Du family and Uncle Liu.

Accounted for.

If I remember correctly in my previous life, during the 2008 World Games in Beijing, the bus system in Beijing also purchased a batch of energy buses in large quantities, but those buses all used hybrid power systems provided by Foton, and

Their battery pack uses lithium manganate batteries.

This kind of battery has certain advantages compared with nickel-metal hydride batteries, but compared with lithium iron phosphate batteries, it can only be said to be scum, cannot work at low temperatures, has a short service life, etc. These are all problems.

The most critical thing is that this kind of battery is not suitable for strong hybrid systems and has considerable deficiencies in external plug-in charging, which directly condemns this kind of battery to death in the future of lithium batteries.

Now that I have a better substitute in my hands, I believe that in the near future, more large hybrid vehicles with the Huayang Power logo will appear on the Beijing bus system.

However, we cannot take it lightly. When making this kind of battery, the sealing must be perfect, otherwise the lithium battery will catch fire and explode. It is no joke...

Thinking about the BYD electric taxi that was hit and then exploded into flames in later generations, Jin Xiaoqiang suddenly felt shuddering. Such a thing is absolutely not allowed to happen to Huayang Dynamics... (To be continued. If you like this
