Dong Dong Dong——————
There was a knock on the office room door.
Xu Yifan, who was sitting behind his desk, closed 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 has finally lived up to expectations and completed the research and development of new lithium iron phosphate batteries!"
Even though he had learned the detailed information about this technology through the system, Xu Yifan still asked: "How is the performance of our battery?"
Lu Jingping briefly explained the battery information once.
“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 due to the inherent limitations of materials, it is still not as good as ternary lithium batteries, but it is not far behind.
In terms of cycle life, it still has more than 80% capacity after 5,000 cycles. It can be said to be the top lithium iron phosphate battery in China today!
However, this was made under laboratory conditions. Considering the cost and manufacturing process, the performance of the final mass production may be slightly worse. "
After listening carefully once, Xu Yifan murmured.
“Energy density, I remember that current lithium iron phosphate batteries are limited by materials. Most of them hover around 80~100Wh/kg, and few can reach 110~130Wh/kg.
And at 150Wh/kg, our battery is already top-notch today! "
"The capacity in low-temperature environments can actually reach 65%. I remember that I learned about BYD before, but the current battery technology seems to be only about 60%."
"At the same time, in terms of high-temperature performance, lithium iron phosphate is also safer. Even if there is a short circuit, it will have to burn to 700 degrees before deflagration. Even if there is a short circuit, it is very difficult to cause an accident!"
“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 elements, they can be synthesized from phosphate ore and iron ore. "
"Lithium iron phosphate batteries and ternary lithium batteries each have their own advantages and disadvantages. The ternary battery has high energy density, is expensive, is relatively unstable and prone to spontaneous combustion, and has good low-temperature performance.
Phosphate batteries are heavier and cheaper, but are less flammable, have more discounts in the winter, and have more charge cycles.
For today's Jiuzhou Automobile Factory, lithium iron phosphate is more suitable, which is more stable, has lower manufacturing price, has a longer service life, and does not require high manufacturing technology. "
"With five thousand cycles, even if you charge it once a day, it can be used for five thousand days, which is more than thirteen years, and more than ten years later, it will still have 80% of the battery life of a new car.
Even if it has a battery life of 100 kilometers, ordinary people will need several days to charge it once, which means that there is basically no need to worry about battery cycle life! "
"Instead of worrying about the battery, it is better to worry about the other parts of the vehicle having problems in ten or twenty years. The probability is much higher than the battery!"
Seeing his boss easily talking about battery technology that most people have not paid attention to nowadays, Lu Jingping couldn't help but praise: "The boss is awesome!"
Xu Yifan was also very happy and couldn't hide the smile on his face. "With such excellent batteries, the next development plan of the factory will be easier to carry out."
In fact, compared with battery technology more than ten years later, this battery can only be said to be average.
But who says it’s only 2009? It’s already enough for Kyushu Motors to be far ahead of its friends!
I talked with Lu Jingping about the various performances of the new lithium iron phosphate battery.
Xu Yifan thought of these heroes who had not returned home during the New Year and asked: "By the way, where are the brothers now?"
Lu Jingping replied: "I'm still doing some finishing work in the laboratory. When the project is completed, I'll come over and notify you as soon as possible."
After finishing speaking, he sighed again and said: "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 said it was the boss's money offensive that made us tireless, like God's help!"
Xu Yifan smiled and shook his head: "It's you who are great. Without you, it might be difficult to complete the research and development of this technology in a short time no matter how much money is spent."
"Call everyone out tonight, have a good meal together to celebrate, barbecue hot pot, wash your feet and get a massage, I have to treat everyone well!"
"You can count them later and see what everyone wants to eat."
Lu Jingping smiled and said: "There are several people in the group who are really looking forward to the boss taking us to play together!"
With a knowing smile on his face, Xu Yifan continued:
"By the way, as for the next work arrangements, as I promised you before, after the battery project research and development is completed, we can give you compensatory time off.
After everyone’s work arrangements are completed, we can start.
However, according to the method we discussed before, some people will rest first, and some people will rest later.
We cannot all go to rest, otherwise the construction of the factory will have to come to a standstill.
Now is the time to grab time, and we can’t let everyone have a good rest yet.
The factory has just started, and problems can easily occur if you are not careful. I also know that everyone is working very hard and has not had a break for a long time.
When the factory gets back on track in the future, everything it should have will be available, including annual leave, weekend breaks, better accommodation and R&D environment, etc. "
Lu Jingping nodded and expressed his understanding: "I have told everyone about the rotation of rest before, and everyone understands it 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 also be carried out next.
Well, I forgot to mention it in the meeting two days ago. The factory is big and the legal personnel must be fully equipped.
I will ask Lao Ma to work overtime later and build a simple legal framework in the past two days.
Wait for two days, and then I will bring one of our brothers and work with our factory's legal affairs officer to complete the patent registration for the new lithium iron phosphate battery. "
"Okay, let Qiu Haowei go with you then, he is more familiar with patent registration.
Moreover, the intention of chatting before was not that I was particularly anxious to go home and rest. On the contrary, I would be very happy to be able to drive a luxury car on business with my boss! "
Xu Yifan nodded slightly and thought for a while, there was nothing to arrange for the time being: "These should be enough."
"Okay, you go back and tell everyone about the upcoming work arrangements and tidy up the laboratory. We won't go home until we get drunk tonight!"
After Lu Jingping nodded in agreement, he quickly left.
The office became quiet again, and Xu Yifan was silent.
All the things that need to be ordered have been given, and various departments are working hard to expand and move forward according to the set goals.
Next, just do the last thing, and you can wait with peace of mind.
After two or three months, Jiuzhou Automobile Factory entered into a period of great development.
And this matter is the production capacity issue that has always restricted the development of Jiuzhou Automobile Factory.
It's time to visit those automobile factories in the province and talk about OEM matters.
