Technological power starts with upgrading lenses

On the day Kangchi visited CATL, CATL's lithium battery R\u0026D laboratory conducted a professional test and analysis on the sodium battery brought by Kangchi, and submitted the specific analysis results to Zeng Yuqing on the third day .

Analysis of the data showed that this was indeed a sodium-ion battery.

And it’s an all-solid-state sodium battery with an energy density of up to 300Wh/kg!

Its anode material boldly uses metallic sodium and some kind of amorphous carbon, which is the key to achieving high energy density in solid-state batteries.

The cathode material uses some kind of metal-like oxide and polyanionic compound.

The electrolyte is a solid high-valent sulfide or some kind of oxide.

In other words, most of the positive and negative electrodes and electrolytes of this battery are new materials that they have never seen before!

As for the diaphragm?

All-solid-state batteries don't need this stuff at all.

In traditional lithium batteries, lithium ions react with the liquid electrolyte during the back and forth movement of discharge and charge, forming a lithium dendrite.

Lithium dendrites are like a hard branch that slowly expands during battery use, eventually connecting the positive and negative electrodes.

The result is short circuits, fires and explosions.

The separator is something sandwiched between the positive and negative electrodes that slows down the growth rate of lithium dendrites.

However, no matter how good the separator is, it can only delay the occurrence of lithium dendrites and cannot truly prevent the occurrence of lithium dendrites.

Therefore, if lithium batteries are used for a long time, are used improperly, are of poor quality, or are extruded and deformed, lithium dendrites may pierce the separator, eventually causing short circuits, fires, and explosions.

Although solid-state batteries may also produce lithium dendrites, the electrolyte of solid-state batteries is all solid, so the electrolyte itself is the separator.

Such a thick 'separator' is difficult to be pierced by lithium dendrites or nanodendrites, causing short circuit, fire and explosion.

Even if it does get punctured, the solid electrolyte is difficult to burn, let alone decompose oxygen, directly nipping the risk of combustion in the cradle.

This is why solid-state batteries are much safer than liquid batteries.

High energy density + safety,

Solid state batteries are really awesome.

It's a pity that this cake has been painted for so long in the Ningde era, but it has not been available for everyone to eat.

On the contrary, Kangchi not only brought out solid-state batteries, but also sodium-ion solid-state batteries.

This is simply more fragrant than fragrant!

After receiving the analysis report, Zeng Yuqing pondered for a long time, and then began to convene the company's board of directors. After several discussions for three consecutive days, he and the directors went to Dongyang to witness Datang Heavy Industries' nanobattery production line with his own eyes before finally making a unanimous decision. :

Adapt to the times and retreat bravely from the rapids!

CATL agreed to sign a strategic cooperation agreement with Datang Heavy Industry and became Datang Heavy Industry's long-term sodium battery OEM enterprise.

In order to further consolidate the strategic cooperative relationship between the two parties, ensure that Datang Heavy Industry has a certain influence on major decisions of CATL, and supervise the technical confidentiality of sodium batteries,

CATL will also receive a total of 73 billion in financing from Datang Heavy Industry to ensure that Datang Heavy Industry holds at least 10% of the shares in CATL and can appoint two additional board members.

Of these 10% shares, 7% will be diluted in equal proportions by CATL’s original major shareholders.

The remaining 3% will be transferred by financial companies through the stock market.

Because a large part of the lithium battery orders signed by Ningde Era have not yet been delivered, it is impossible to say transformation and complete transformation immediately.

In the early stage, the main focus was on improving and upgrading production lines with overcapacity.

At the same time, they will stop accepting orders for power and energy storage lithium batteries and gradually complete the conversion of lithium-sodium production lines.

In addition, all midstream and upstream lithium battery companies also need CATL to coordinate industrial transformation, and the entire project volume and task volume are quite large.

"...That's probably what happened."

Zhang Qing, who had just returned from Ningde, immediately gave a work report to Kang Chi.

"They hope that we can send a technical team to guide their R\u0026D technical team to complete the transformation and upgrade of the production line."

After hearing this, Kang Chi breathed a sigh of relief, nodded and said, "Let Dr. Yan lead the team."

"Okay, in addition, CATL also made a request. They hope that we can license the relevant patents for solid-state sodium batteries to them. They want to retain part of the lithium battery production line and R\u0026D department, and then use solid-state sodium battery technology to manufacture them. High-end lithium batteries will mainly target customer groups in the aviation industry, military industry and other high-end fields in the future."

"Well, that's no problem," Kang Chi nodded directly, "In fact, even if they don't mention it, I will suggest them to do it later."

Zhang Qing couldn't help but breathed a sigh of relief after hearing this.

In fact, during Ning De's negotiation, she guessed that Kang Chi would agree to this request, so she verbally agreed to Zeng Yuqing's request, otherwise the negotiation would not go so smoothly.

"Then if there's nothing else, I'll leave first. I'll probably have to run to Ningde again in the afternoon."

"Well, thank you for your hard work...wait a minute, I have something else that must be done by you..."

When Zhang Qing heard that something was going on again, she couldn't help but asked nervously: "What's going on? You're not going to start another big project, are you?"

Seeing Zhang Qing's overwhelmed expression, Kang Chi felt embarrassed.

Ever since she came to Longteng Technology, she has been as busy as a top all day long, constantly traveling around Dongyang, Gangcheng, Pingjiang, Magic City, Yanjing and other places.

Now we have added the CATL and battery swap station projects...

It's really hard work.

But Li Chen's filmmaking is her old profession, and she really has to do it.

"Um...Li Chen is going to use Daqin Optics' Tongwu camera to shoot a theatrical movie about Wu An and me. What do you think?"

"A movie about You and Wu An?"

Zhang Qing's eyes lit up after hearing this, and she immediately nodded and said, "I think this is possible!"

"From a film investment perspective, everyone in China now knows your reputation as Dr. Kang Da, so this gimmick with you as the prototype of the story has a certain box office guarantee."

"From a business perspective, he used Tongwu cameras to shoot Wu'an, and it was also a real theater movie. This is the best way to promote Daqin Optics."

"Especially since he is still a college student, a new director who has never made a movie, and uses the new camera we made..."

"Once the movies produced by this combination are of online quality and can achieve good box office results, then for us, there will be more topics that can be hyped in the future."

“For example, ‘With Tongwu, everyone can be a director’, ‘With Tongwu Camera, you can realize your movie dream’ and so on.”

"This is definitely more effective than spending tens of millions on celebrity endorsements or advertising everywhere!"

"To say the least, even if the box office fails to recoup the cost, just consider it as spending a lot of publicity expenses to advertise Daqin Optics. No matter what, you won't lose too much."

"But all this has a premise, that is, even if the story is weak, it is okay, but the pictures must be beautiful and stunning! It is best to win a film festival award such as Best Cinematography or Best Visual Effects. "

Hearing Zhang Qing's lucid analysis, Kang Chi couldn't help but call him an expert!

Although he also felt that this matter was an advertisement for Daqin Optics, he was not as thorough as Zhang Qing.

Especially the sentence ‘With martial arts, everyone can be a director’,

Even being a new college student director is no longer a negative point, but has become a plus point that can be hyped.

It simply takes the entertainment industry’s ability to hype up topics to its extreme!
