Chapter 211: Follow the times and retreat bravely!
On the day Kang Chi visited CATL, CATL’s lithium battery research and development laboratory conducted professional testing and analysis on the sodium battery that Kang Chi brought, and submitted the specific analysis results to Zeng Yuqing on the third day.
Analysis data showed that this was indeed a sodium-ion battery.
And it was an all-solid-state sodium battery with an energy density of up to 300Wh/kg!
Its negative electrode material boldly uses metal sodium and some amorphous carbon, which is the key to the high energy density of solid-state batteries.
The positive electrode material uses some kind of metal oxide and polyanion compound, and the electrolyte is a solid high-valent sulfide and some oxide.
In other words, most of the positive and negative electrodes and electrolytes of this battery are new materials 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 liquid electrolytes during the back-and-forth movement of discharge and charge to generate something called lithium dendrites. Lithium dendrites are like hard tree branches that slowly expand during the use of the battery and eventually connect the positive and negative electrodes. The result is short circuit, fire, and explosion. The diaphragm is something that is sandwiched between the positive and negative electrodes to slow down the growth rate of lithium dendrites. However, no matter how good the diaphragm is, it can only play a delaying role and cannot really prevent the appearance of lithium dendrites. Therefore, if the lithium battery is used for a long time, improperly used, of poor quality, or extruded and deformed, lithium dendrites may pierce the diaphragm, eventually causing short circuit, fire, and explosion. Although solid-state batteries may also produce lithium dendrites, the electrolyte of solid-state batteries is all solid, so the electrolyte itself is the diaphragm. Such a thick “diaphragm” is difficult to be pierced by lithium dendrites or nanodendrites, resulting in short circuits, fires, explosions, etc. Even if it is pierced, the solid electrolyte is difficult to burn, and will not decompose oxygen, directly killing the hidden danger of combustion in the cradle.
This is why the safety of solid-state batteries is much higher than that of liquid batteries.
High energy density + safety, solid-state batteries are really good.
It’s a pity that CATL has been drawing this pie for so long, but it has not been brought out for everyone to eat.
On the contrary, Kangchi not only brought out the solid-state battery, but also the sodium ion solid-state battery.
This is simply a fragrance on top of fragrance, it can’t be more fragrant!
Zeng Yuqing, who got the analysis report, pondered for a long time, and then began to convene the company’s board of directors. For three consecutive days, he held many discussions, and went to Dongyang with the directors to witness the nano battery production line of Datang Heavy Industry with his own eyes. Finally, they unanimously decided: Follow the times and retreat bravely!
CATL agreed to sign a strategic cooperation agreement with Datang Heavy Industry and become a long-term OEM for sodium batteries of Datang Heavy Industry.
In order to further consolidate the strategic cooperation relationship between the two parties, ensure that Datang Heavy Industry has a certain influence on the major decisions of CATL, and supervise the technical confidentiality of sodium batteries, CATL will also accept a total of 73 billion yuan in financing from Datang Heavy Industry to ensure that Datang Heavy Industry holds at least 10% of CATL’s shares, and can send two additional board members.
Of these 10% of shares, 7% will be diluted in equal proportion by CATL’s original major shareholders, and the remaining 3% will be transferred by financial companies through the stock market.
Because a large part of the lithium battery orders signed by CATL before have not been delivered, it is impossible to say that the transformation will be fully transformed immediately.
In the early stage, it is mainly to improve and upgrade the 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 mid- and upstream lithium battery companies also need CATL to coordinate industrial transformation, and the entire project volume and task volume are quite large.
“… This is probably the situation.”
Zhang Qing, who had just returned from Ningde, immediately reported to Kang Chi. “They hope that we can send a technical team to guide their R&D technical team to complete the transformation and upgrade of the production line.”
Kang Chi also breathed a sigh of relief after hearing this and nodded: “Let Dr. Yan lead the team.”
“Okay, in addition, CATL also made a request. They hope that we can use the solid-state sodium batteryThe patents are licensed to them. They want to retain some lithium battery production lines and R&D departments, and then use the technology of solid-state sodium batteries to manufacture high-end lithium batteries. The main customer groups in the future will be high-tech fields such as aviation industry and military industry. ”
”Well, that’s no problem,” Kang Chi nodded directly, “In fact, even if they don’t mention it, I will suggest them to do so later.”
Zhang Qing couldn’t help but breathe a sigh of relief after hearing this.
In fact, when negotiating with Ningde, she guessed that Kang Chi should agree to this request, so she verbally agreed to Zeng Yuqing’s request, otherwise the negotiation would not be so smooth.
”If there is nothing else, I will leave first. I guess I will have to go to Ningde again in the afternoon.”
”Well, thank you for your hard work… Wait, I have something that only you can do…”
Zhang Qing couldn’t help but ask nervously when she heard that there was something else, “What’s the matter? Are you going to do another big project? ”
Kang Chi felt embarrassed when he saw Zhang Qing’s overwhelmed expression.
Since she came to Longteng Technology, she has been busy like a top all day, constantly moving around Dongyang, Gangcheng, Pingjiang, Shanghai, Yanjing and other places. Now she has added the Ningde era and the battery swap station project…
It is really very hard.
But Li Chen’s filming is her old profession, and she is the only one who can do it.
”That… Li Chen is going to use Daqin Optics’ Tongwu camera to shoot a theater movie about me and Wu An. What do you think?”
”You and Wu An’s movie?”
Zhang Qing’s eyes lit up after hearing this, and she immediately nodded and said, “I think this is possible!”
”From the perspective of film investment, everyone in China now knows your reputation as a doctor of Kangda, so this gimmick with you as the prototype of the story has a certain box office guarantee. ”
“From a commercial perspective, he used Tongwu cameras to shoot Wu’an, and it was a real cinema movie, which is the best way to promote Daqin Optics.”
“Especially since he is a college student, a new director who has never made a movie, and he uses our new camera…”
“Once the level of the movie shot by this group is online and can achieve good box office results, then for us, there will be more topics to hype in the future.”
“For example, ‘Using Tongwu, everyone can be a director’, ‘Tongwu camera, fulfill your movie dream’ and so on.”
“This is definitely more effective than spending tens of millions to invite celebrities to endorse or advertise everywhere!”
“Take a step back and say that even if the box office cannot recover the cost, it is just a publicity fee spent on advertising for Daqin Optics, and it will not lose too much anyway.”
“But all this has a premise, that is, even if the story is a little weak, it doesn’t matter, but the pictures must be beautiful and amazing! It would be best if it could win a film festival award such as Best Photography or Best Visuals. ”
Hearing Zhang Qing’s well-reasoned analysis, Kang Chi couldn’t help but call himself an expert!
Although he also felt that this matter was an advertisement for Daqin Optics, he didn’t think as thoroughly as Zhang Qing did.
Especially the sentence ‘With Tongwu, everyone can be a director’, even college students and new directors are no longer a deduction, but a plus point that can be hyped.
It simply brings the entertainment industry’s ability to hype topics to the extreme! (End of this chapter)
