Technology overlord starts with new energy vehicles

Boom boom boom —————

There was a knock on the door of the office room.

Xu Yifan, who was sitting behind the desk, turned off the game on the computer screen, and said calmly, "Please come in."

The door was pushed open, and Lu Jingping walked in with a smile on his face.

"Boss, our battery laboratory finally lived up to expectations and completed the research and development of a new type of lithium iron phosphate battery!"

Even after learning the detailed information of this technology through the system, Xu Yifan still asked: "How is the performance of our battery?"

Lu Jingping briefly explained the information about the battery.

"The performance is very good, the energy density is 150Wh/kg.

It has good high and low temperature resistance and can reach 65% capacity at minus 20 degrees.

Although it is still not as good as the ternary lithium battery due to the inherent limitations of the material, it is not too far behind.

In terms of cycle life, there is still more than 80% of the capacity after 5000 cycles, which can be said to be the top lithium iron phosphate battery in China today!

However, this is produced under laboratory conditions. Considering the cost and manufacturing process, the performance of the final mass production may be slightly worse. "

After listening carefully, Xu Yifan murmured.

"Energy density, I remember that current lithium iron phosphate batteries are limited by materials, most of them hover at 80~100Wh/kg, and few can reach 110~130Wh/kg.

And if it is 150Wh/kg, our battery is already top-notch now! "

"The capacity in a low-temperature environment can actually reach 65%. I remember that BYD, which I have known before, seems to have only about 60% of its current battery technology."

"At the same time, in terms of high-temperature performance, lithium iron phosphate is also safer. Even if it is short-circuited, it must be burned to 700 degrees to deflagrate. It is difficult to cause an accident if it is short-circuited!"

"The preparation technology of iron phosphate is much lower than the manufacturing cost of ternary lithium batteries, which require the use of rare metal nickel and cobalt materials.

Lithium iron phosphate materials are relatively simple and cheap to obtain. In addition to lithium, only phosphate ore and iron ore can be synthesized. "

"Lithium iron phosphate battery and ternary lithium battery have their own advantages and disadvantages. The ternary battery has high energy density, is expensive, relatively unstable and more prone to spontaneous combustion, and has good low-temperature performance.

Phosphoric acid batteries are heavier and less expensive, but are not flammable, have more discounts in winter, and have more charge cycles.

For today's Kyushu Automobile Factory, lithium iron phosphate, which is more stable, has a lower manufacturing price, has a longer service life, and does not require too high a manufacturing technology, is more suitable. "

"The number of cycles of 5,000 times, even if it is charged once a day, can be used for 5,000 days, that is, more than 13 years, and after more than ten years, it still has 80% of the battery life of a new car.

And even with a battery life of 100 kilometers, ordinary people need several days to charge once, which means that there is basically no need to worry about the battery cycle life! "

"Instead of worrying about the battery, it's better to worry about problems with the rest of the vehicle's components after ten or twenty years. The probability is much greater than that of the battery!"

Seeing that the boss easily talked about the battery technology that most people have never paid attention to, Lu Jingping couldn't help but praise: "The boss is amazing!"

Xu Yifan was also very happy and couldn't hide the smile on his face. "With such an excellent battery, the next development plan of the factory will be carried out better."

In fact, compared with the battery technology more than ten years later, this battery can only be said to be average.

But who knows that it is only 2009, which is enough for Kyushu Automobile to be far ahead of its competitors!

Chatted with Lu Jingping about the performance of the new lithium iron phosphate battery.

Xu Yifan thought of those heroes who didn't go home during the Chinese New Year, and asked, "By the way, where are the brothers now?"

Lu Jingping replied: "I'm still dealing with some finishing work in the laboratory. I will notify you, the boss, as soon as the project is completed."

After finishing speaking, he sighed again: "To be honest, everyone can't believe it now. We actually developed a new type of lithium iron phosphate battery in such a short period of time."

Lu Jingping said with a smile: "Everyone says it's the boss's money offensive, which makes us tireless, like a god's help!"

Xu Yifan smiled and shook his head: "It's you who are amazing. Without you, no matter how much money you spend, it may be difficult to complete the research and development of this technology in a short period of time."

"Call everyone out at night, have a good meal together to celebrate, barbecue hot pot, wash your feet, massage and walk, I have to reward everyone!"

"You will make statistics later to see what everyone wants to eat."

Lu Jingping said with a smile: "There are quite a few people in the group, but they all look forward to the boss taking us to play together!"

With an understanding smile on his face, Xu Yifan went on to say:

"By the way, the next work arrangement, I promised everyone before that after the completion of the battery project research and development, I can give everyone a compensatory rest.

Everyone's work arrangement is completed, and then we can start.

However, according to the way we discussed before, some people will rest first, and some people will rest later.

We can't all go to rest. In that case, the construction of the factory can only come to a standstill.

Now is the time to scramble for time, and we can't let everyone have a good rest.

The factory has just started, and it is prone to problems if you don't pay attention. I also know that everyone has worked very hard and have not rested for a long time.

When the factory is on the right track in the future, everything that should be available will be available, such as annual leave, weekends, better accommodation and R\u0026D environment, etc. "

Lu Jingping nodded, expressing his understanding: "I have already told everyone about the rotation, and everyone understands very well.

In fact, everyone is very satisfied with the current working environment. Of course, if it can be better, I believe everyone will be very happy! "

Xu Yifan thought for a while: "There is also patent registration, which will be carried out next.

Well, I forgot to mention it during the meeting two days ago, the factory is big, and the legal staff must be fully equipped.

Later, I will let Lao Ma work overtime, and build a simple legal framework in the past two days.

Wait for two days, then I will take one of our brothers and work with our factory's legal counsel to complete the patent registration of the new lithium iron phosphate battery. "

"Okay, then let Qiu Haowei go with you, he is more familiar with patent registration.

And the intention of chatting before was not particularly anxious to go home and rest. On the contrary, it must be very happy to be able to drive a luxury car with the boss and go out on business! "

Xu Yifan nodded slightly, thought for a while, and there is nothing to arrange for the time being: "These should be almost done."

"Okay, let's go back and tell everyone about the next work schedule, clean up the laboratory, and let's not get drunk at night!"

After Lu Jingping nodded in agreement, he left quickly.

The office was quiet again, and Xu Yifan remained silent.

All the things that should be ordered have been ordered, and various departments are also fully expanding, moving forward according to the established goals.

Next, do the last thing well, and you can wait with peace of mind.

After two or three months, the Kyushu Automobile Factory has entered into a major development.

And this matter is the production capacity problem that has been restricting the development of Kyushu Automobile Factory for a long time.

It's time to visit those auto factories in the province and talk about OEM.

Ask for votes, ask for follow-up.

Hand it all over!
