[Item status: intact]

[Analysis item: parsable]

[General experience: 109894]

[Mastery Points: 56]

After returning home, Kang Chi dug out a piece of sodium ion electron disassembled from an oil-producing insect.

He had been hiding this thing for a while. One reason was that he didn't have time to work on it at the time, and the other was because he was afraid of the collapse of the lithium battery industry, so he couldn't think of an entry point to launch this technology.

But as the situation opened up, he also figured it out.

In fact, he doesn't need to think so much at all. Even if this thing destroys the lithium battery and revolutionizes the lives of traditional fuel car companies, a new sodium battery industry will rise and new new energy car companies will emerge.

Or it may be them who will complete this industrial transformation.

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

When analyzing the oil bug, Kangchi had actually obtained the technical information of this battery and knew that it was actually a semi-solid sodium-ion battery that achieved 300Wh by doping the original liquid electrolyte with an oxide. /kg energy density.

At that time, the battery was just a component of the oil-mining insect, and the analysis only yielded technical information and no specific processing technology.

But what he wants to do now is not to rush to obtain the processing technology, but to explore the limits of sodium batteries.

Kangchi directly upgraded this battery.

General experience-5000,

General experience-15000,

[The level of this item has reached the upper limit]

So fast?

After upgrading two levels in a row, Kang Chi unexpectedly discovered that an unprecedented pop-up window appeared in the system.

It turns out that there really is an upper limit to item levels.

However, this is also in line with Kang Chi’s previous speculation. After all, no matter what technical route it is, there will definitely be a limit. For example, no matter how you upgrade silicon-based semiconductor chips, the physical limit of the 1.5-2 nanometer process is there. Although this system Awesome, but so far, it has never subverted the basic laws of physics.

[Item: Sodium-ion battery]

[Manufacturer: Kangchi]

[Item level: 6 (full level)]

[Energy Density: 500Wh/kg]

[Item status: intact]

[Analysis item: parsable]

[General experience: 89894 (-20000)]

[Mastery Points: 56]

500Wh/kg!

After seeing this number, Kang Chi couldn't help but take a breath.

Although the upper limit of the level 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 already delicious enough!

Mastery points -10.

Kangchi immediately conducted a technical analysis of this battery.

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

This sodium-ion battery has a pure solid electrolyte, so it is a sodium-ion solid-state battery. Its composition includes the high-priced sulfide MoS3, and... yttrium oxide!

This is a bit cheating.

The price of yttrium oxide in China is much cheaper than that of lithium carbonate, only 5-6 yuan per ton.

But once demand rises, prices will definitely surge.

the reason is simple,

It is a rare earth resource!

As the first rare earth element discovered by humans, yttrium oxide has 22 tons of resource reserves in my country, accounting for 43% of the world's total reserves, ranking first.

But compared with the global resource of 3.49 million tons of lithium carbonate, the global 51 tons of yttrium oxide is definitely a rare resource.

The reason why it is not expensive now is because its current demand is not high and there are export controls.

Although manufacturing one ton of level 6 sodium-ion batteries, the consumption of yttrium oxide is actually very small, only 0.5KG.

Calculated according to the energy density of level 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 level 6 sodium-ion batteries requires the consumption of 390 tons of yttrium oxide, 22 Tons of reserves appear to last for more than five hundred years.

But the problem is that with the promotion of new energy and energy storage, battery production capacity will definitely increase. Now it is enough to last for more than 500 years, but in the future it may be gone in a hundred years.

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

So overall, small-scale construction in the early stage is okay, but large-scale construction is definitely not possible.

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

Kang Chi took another level 4 sodium-ion battery, upgraded it to level 5, and spent 5 proficiency points to analyze it, which verified his conjecture.

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

It is the optimal solution for sodium-ion batteries!

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

Kangchi spent another 5 proficiency points to analyze the manufacturing process of level 5 sodium-ion batteries, and then @@yanhui, Zhang Qing, Wang Haowen, Fang Qiming, He Yongbin, and Ming Yuhan in the group executive group Wait for the heads of the main companies in the group and ask them to bring the main backbone of the company, and hold a high-level meeting of the group at Datang Heavy Industry the day after tomorrow.

After receiving the notice, everyone was a little surprised.

This kind of meeting where the company's top executives gathered together has never been held by Kangchi before, so I am very curious about Kangchi's purpose of holding this meeting.

While everyone was constantly speculating in their minds, two days passed quickly. On June 6st, the first high-level meeting of Longteng Technology Group was finally held in Dongyang.

After everyone met, they naturally exchanged greetings first, and then all focused their attention on Zhang Qing.

As the group general manager responsible for helping Kangchi coordinate the group's subsidiaries, everyone wondered if she had any inside information. In the end, Zhang Qing just shook her head gently, saying that she did not know the purpose of Kangchi's meeting. What.

"Is everyone here?"

While everyone was still discussing, Kang Chi's voice suddenly came from the door, so everyone quickly stood up to say hello.

"Mr. Kang."

"Everyone is here and waiting eagerly for you."

"..."

Kang Chi smiled at them, then waved his hand for everyone to sit down: "Thank you for your special trip. Now that we are all here, let's get started."

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

Everyone nodded, this was similar to what they had guessed before.

Kang Chi first looked at Fang Qiming and He Yongbin and asked: "How is the camera business and the delivery of mobile phone cameras? Is there a lot of pressure?"

Fang Qiming quickly reported: "Although there is a certain pressure, it is not a big problem. We have placed an order for three more production lines with Datang Heavy Industries, one of which will be used for the subsequent manufacturing of mid-to-low-end mobile phone lenses, and two for the military." We manufacture sights and also outsource some orders for camera lenses.”

Kang Chi nodded: "Then you can add another lens and camera production line."

"After Director He completed the research and development of mid-to-low-end mobile phone cameras, he immediately started to develop medium-format video cameras and lenses. I will send you the specific mount parameters and other hard requirements tomorrow. It will be the same as the last time we developed Wuan. Show me the prototype first when you come out."

Medium format video cameras and lenses!

In fact, they had long heard that Kangchi had assigned the research and development task of a high-end medium format film and television grade sensor when he accompanied Wang Haowen to Dahan Core Industry some time ago.

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

If this project succeeds, it means that Daqin Optics has completed the upper and lower attack on the digital camera giants of the island nation. Then, as long as it deploys two products in the middle, it will basically be able to annihilate them all!
