Spend money to play around the world

"Is that so?" Chen Fang nodded slightly.

Although he lacks an in-depth understanding of professional new energy knowledge, he does not understand everything. He can still understand the basic concepts mentioned by Lin Shuang.

Lin Shuang went on to talk: "At present, the battery pack with the largest capacity for new energy vehicles in the market should be the semi-solid battery of Weilai ET7, but many people in the industry are not optimistic about Weilai, thinking that it is mostly hyped. And the new car won't be delivered until next year.

Therefore, the currently recognized best battery is still Tesla's 4680 electrodeless battery.

But even so, limited by the size and weight, when the 4680 battery is assembled on the car, it can only achieve 100 kWh.

But our first-generation lithium-air battery, because of its high energy density, can use a lighter weight than the 4680 battery, allowing the battery pack to triple its power.

If you increase the weight and increase the volume, it is not a problem to reach 4 times or even 5 times of them.

But there is no need for that, 3 times the battery capacity can already subvert the entire battery industry. "

Because of the high energy density, lithium-air batteries can be so bold.

However, this is only the first-generation lithium-air battery developed by Yinhe Battery Company. When the second-generation and third-generation lithium-air batteries come out, the energy density will be even higher.

I heard Yang Xuedong mentioned before that if the technology of lithium-air batteries is improved, it will not be difficult to break through 2000wh/kg.

Of course, until no company can break the limit of 1200wh/kg, Yinhe Battery Company does not need to introduce higher energy density technology.

Mainly there is no need for that.

"What about the test in low temperature weather?" Chen Fang asked again.

Lin Shuang shook his head: "It's summer now, and it's still in May and June. The actual measurement in low temperature weather can't be done in the mainland.

However, we have reached a cooperation with the Changan Group, and we are arranging a team to go to the low-temperature areas in northern Russia to conduct actual measurements, and the results will be available soon.

In addition, according to the previous tests done by our company's laboratory personnel, low temperature weather does have some impact on the activity of lithium-air batteries, but the impact is not significant.

As long as the battery pack supplies energy to heat itself first, there will be no problem, and the time is not long, only about half a minute. "

Lin Shuang continued to say with a smile: "In low temperature weather, the electricity is estimated to be 300 kilowatt-hours, so even if you can't run 2000km, it shouldn't be difficult to run 1800km.

And not to mention the battery life of 1800km, even with a discount, the battery life is reduced by one-third, and the battery life is only 1200km. Our lithium-air battery is still a unique product in the market, and no battery company can do it.

Of course, even if there are companies that can increase the capacity of battery packs, we can fully rely on the ultra-high energy density of lithium-air batteries and continue to lead them by increasing the weight of battery packs. "

Chen Fang nodded in agreement. With technological hegemony in his hands, it is not difficult to achieve continuous leadership.

Lin Shuang stroked her hair, and then said: "So, after the results of the test comparison at the proving ground a few days ago, Changan Automobile Group also knew the terrible performance of lithium-air batteries.

In order to be the first car company to eat peaches, they quickly placed an order of 10 billion and ordered the first batch of lithium-air battery packs from us.

And in order to cater to the problem of oxygen enrichment in lithium-air batteries, they also intend to design and launch a new pure electric vehicle..."

Hearing this, Chen Fang understood why Chang'an Group placed an order in advance.

It is estimated that the people of Changan Automobile's eyes were red after seeing the test results, right?

Under normal weather, the battery life of the original car of about 400 kilometers has soared by more than 5 times, and no one can stand it.

However, in Chen Fang's opinion, Chang'an Automobile Group dared to place an order first-hand, but it was indeed quite discerning, and the road was widened.

After thinking about it, Chen Fang asked, "By the way, what is the cost of the lithium-air battery?"

Lin Shuang replied: "The specific cost is still unclear, the factory in the Mengshan area has not yet been built, and the results can only be calculated after mass production and sales.

However, according to professional estimates, thanks to the new technology of lithium-air batteries, the cost of making a lithium-air battery pack with a capacity of 300 kWh should not exceed 5 yuan, which is about 1-1 cents for 2wh of electricity.

At present, the cost of other batteries on the market, even Tesla's, is generally more than 1 yuan per 1wh. "

……

383 , Domineering Chen Fang

In fact, whether the battery, especially the power battery of new energy vehicles, can be widely accepted by the market, although the level of energy density is fundamental, in practical applications, the cost is also very important.

If the cost is too high, it costs 1 yuan to make a 1wh battery, and a 300-kwh battery pack costs a full 30 yuan.

At this time, considering that Yinhe Battery Company wants to make money and profit, the price of a set of 300 kWh battery packs is far more than the cost price of 30.

It will undoubtedly be higher than this.

Under such circumstances, the car companies that buy batteries cannot be low-end car companies, but must be high-end brands such as BBA, or even luxury brands such as Ferrari, Lamborghini, Porsche and Bentley.

In this way, it can be predicted that although the price is high, because the selling price base is relatively high, and the profit of a single product is quite considerable, it has lost a large number of low-end and middle-end markets.

After a year, it would be nice to make a profit of billions, but lose tens of billions, even hundreds of billions, or trillions of low-end mass market.

In this world, expensive things do make money, there is no doubt about it, but the ones that make the most money are often those low-end products, or even some simple daily necessities.

For example, Nongfu Spring, which costs two yuan a bottle, does not seem very eye-catching and is very cheap, but because it serves the public, everyone can afford it, and has a large consumer base, but it can directly create a large group with a market value of hundreds of billions.

Therefore, whether it is Chen Fang or Lin Shuang, the idea at the beginning is actually to hope that lithium-air batteries can be accepted by the low-end market.

And this premise is that the cost should not be too high.

At present, because lithium-air batteries are a new technology, the manufacturing process is different from traditional batteries. Although the energy density and battery capacity have been improved, the cost has been reduced.

This is the great advantage brought about by technological innovation.

But in any case, it is a mature technology decades later. If there is not even this small advantage, then the urine of the wealth system may not allow Chen Fang to trade the technical information of lithium-air batteries.

It's just that the production plant of lithium-air batteries is still under construction, and there is still some time before mass production, so don't be too happy now.

It will not be too late to be happy when the factory is completed and mass production and sales begin.

After chatting with Lin Shuang for a while, after understanding the company's various developments and future plans, Chen Fang did not stay here.

After flirting with her a few words, he got up and put his hands in his trouser pockets, and walked out of the office leisurely.

Lin Shuang was left alone and continued to work for him vigorously.

Walking all the way to the front desk, seeing Zhang Chuxue who was immersed in her work, she thought that her fish had been stocked for a long time, and it was time to catch it and put it in her own fish pond.

Why don't you just do it today.

With this in mind, Chen Fang reached out and knocked on the table, and shouted to Zhang Chuxue: "Go, come out with me."

Zhang Chuxue looked up at him, pursed her thin lips and said, "Mr. Chen, I'm still at work."
