After returning home, Kangchi turned over a piece of sodium ion electron that had been disassembled from the oil extractor.

This thing has been hidden by him for a while, one is that he didn't have time to engage in this thing at that time, and the other is afraid of collapsing the lithium battery industry, and he didn't think about what entry point to launch this technology for a while.

But as the pattern opened, he also figured it out.

In fact, he doesn't have to think about it so much, even if this thing collapses the lithium battery and revolutionizes the life of traditional fuel car companies, there will be a new sodium battery industry rise, and there will be new energy car companies.

Or it is up to them to complete the transformation of this industry.

What he really needs to consider is the development prospects of this technology and what the bottlenecks are.

When analyzing the oil production insects, Kangchi has actually obtained the technical information of this battery, knowing that it is actually a semi-solid sodium-ion battery, which is doped with an oxide in the original liquid electrolyte to achieve an energy density of 300Wh/kg.

At that time, this battery was only a part of the oil production worm, and the analysis only obtained technical data, but did not get specific processing technology.

However, what he needs to do now is not to rush to obtain processing technology, but to explore what the limit of sodium batteries is.

Kangchi has directly upgraded this battery.

General experience - 5000,

General experience - 15000,

[This item has reached its maximum level]

So fast?

After upgrading two levels in a row, Kangchi unexpectedly found that the system had never seen a pop-up prompt.

It turns out that there is really an upper limit to the level of the item.

However, this is also in line with Kangchi's previous speculation, after all, no matter what the technical route, there must be a limit, such as how to upgrade the silicon-based semiconductor chip, the physical limit of the 1.5-2nm process is there, although this system is awesome, but so far, it has never subverted the basic physical laws.

[Item: Sodium-ion battery]

【Manufacturer: Kangchi】

[Item Level: 6 (max level)]

[Energy density: 500Wh/kg]

[Item Condition: Intact]

[Parse item: Analyzable]

[General experience: 89894 (-20000)]

[Mastery Points: 56]

500Wh/kg！

After seeing this number, Kangchi couldn't help but gasp.

Although the upper limit of the grade has been stated, the energy density of 500Wh/kg may be the limit of the sodium-ion battery technology route.

But this energy density is fragrant enough!

Mastery points -10.

Kangchi immediately carried out a technical analysis of this battery.

With a large amount of information pouring into his mind, coupled with the knowledge reserve of level 4 sodium-ion batteries, Kangchi quickly digested and understood the technical points of level 6 sodium-ion batteries.

In this sodium-ion battery, the electrolyte has become a pure solid-state, so it belongs to the sodium-ion solid-state battery, and it is composed of a high-valent sulfide MoS3, as well as ......

Yttria!

That's a bit of a trick.

The price of yttrium oxide in China is much cheaper than that of lithium carbonate, only 5-60,000 yuan per ton.

But once demand comes up, prices are sure to surge.

The reason is simple,

It is a rare earth resource!

As the first rare earth element discovered by mankind, yttrium oxide has 220,000 tons of resource reserves in China, accounting for 43% of the world's total reserves, ranking first.

However, compared with the global resource of 349 million tons of lithium carbonate, the world's 510,000 tons of yttrium oxide is definitely a rare resource.

The reason why it is not expensive now is because it is not in high demand right now, and it is also export controlled.

ALTHOUGH A TON OF GRADE 6 SODIUM-ION BATTERIES IS MANUFACTURED, THE CONSUMPTION OF YTTRIUM OXIDE IS ACTUALLY VERY SMALL, ONLY 0.5KG.

According to the energy density of grade 6 sodium-ion batteries, one ton = 500Kwh = 0.5MWH = 0.0005GWh, taking CATL's annual production capacity of 390GWh as an example, if the production of grade 6 sodium-ion batteries requires the consumption of 390 tons of yttrium oxide, and the reserves of 220,000 tons seem to be able to be used for more than 500 years.

But the problem is that with the promotion of new energy and energy storage, the production capacity of batteries will definitely rise, which is enough for more than 500 years now, and maybe it will be gone in 100 years in the future.

Moreover, yttrium oxide is a rare earth after all, and it is impossible to use it to make batteries, which is too wasteful of resources, and it will definitely make sodium-ion batteries lose their biggest cost-effective advantage.

So on the whole, it's okay to build a little bit on a small scale in the early stage, but it definitely can't be built on a large scale.

The most cost-effective sodium-ion battery should be level 5 with an energy density of 400Wh/kg.

Kangchi took another level 4 sodium-ion battery, upgraded it to level 5, and spent 5 mastery points to analyze, and sure enough, it verified his conjecture.

Class 5 solid-state sodium-ion batteries do not use yttrium oxide.

It is the optimal solution for sodium-ion batteries!

Although it wasted 10 proficient points in analyzing the 6-level sodium-ion battery, Kangchi obtained the optimal solution and limit of the sodium-ion battery technology route, which can be regarded as a good gain.

Kangchi spent another 5 points of proficiency to analyze the manufacturing process of the 5-level sodium-ion battery, and then @ Yan Hui, Zhang Qing, Wang Haowen, Fang Qiming, He Yongbin, Ming Yuhan and other major company leaders of the group in the group senior management group, let them bring the main backbone of the company, and hold a high-level meeting of the group in Datang Heavy Industry the morning after tomorrow.

After receiving the notice, everyone was a little surprised.

This kind of meeting of the company's senior management has never been held before, so I am very curious about the purpose of this meeting.

Just as everyone continued to speculate in their hearts, two days passed quickly, and on June 1, the first high-level meeting of Longteng Technology Group was finally held in Dongyang.

After everyone met, they naturally greeted each other first, and then they all focused their eyes on Zhang Qing.

As the general manager of the group, who is responsible for helping Kangchi coordinate the group's subsidiaries, everyone thinks that she has any inside information, but Zhang Qing only shook her head slightly, saying that she also didn't know what the purpose of Kangchi's meeting was.

"Is everyone here?"

Just when everyone was still discussing, Kang Chi's voice suddenly came from the door, so everyone hurriedly got up to say hello.

"Mr. Kang."

"It's all here, and we're all waiting for you."

“……”

Kang Chi smiled at them, and then waved his hand to signal everyone to sit down: "It's hard for everyone to make a special trip, since we have all arrived, let's start directly." ”

"The purpose of letting everyone come here this time is mainly to understand the business situation of each company, arrange the next tasks by the way, and finally the establishment of new projects."

The crowd nodded, which was similar to what they had guessed.

Kangchi first looked at Fang Qiming and He Yongbin, and asked, "How is the delivery of the camera business and mobile phone cameras, is there a lot of pressure?" ”

Fang Qiming hurriedly reported: "Although there is a certain pressure, but the problem is not big, we have placed orders for three more production lines with Datang Heavy Industries, one of which is used for the next low-end mobile phone lens manufacturing, two for the military to manufacture scopes, and also outsourced some orders for camera lenses." ”

Kangchi nodded: "Then you will add another lens and camera production line by the way." ”

"After Director He completed the research and development of low-end mobile phone cameras, he immediately began to develop medium-format video cameras and lenses, and I will send you the specific bayonet parameters and other hard requirements tomorrow, and it is the same as the last time I developed Wu'an, and I will show me the prototype after it is built."

Medium Format Video Cameras and Lenses!

In fact, they have long heard that Kangchi some time ago, when he accompanied Wang Haowen to Dahan Core Industry to take office, he arranged a research and development task of high-end medium-format film and television-level sensors.

Now that the project is finally about to be officially launched, Fang Qiming and He Yongbin couldn't help but be a little excited after hearing it.

If this project is successful, it means that Daqin Optics has completed the encirclement of the digital camera giants in the island country, and then as long as the two products are laid out in the middle, they will basically be able to annihilate them!
