The sudden visit of Mr. Lin of the Mediterranean is of course not a coincidence, but something that Zhang Yimou told him before. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The LED display battery business in the previous Zhang Yimou has been with Chaowei company to negotiate cooperation, although has not signed a contract, but Chaowei company has long regarded this business as a bag.

Of course, without the intervention of Star Company, this business is indeed in their pocket.

That's why when Zhang Yimou told them that this business might be transferred to someone else, they were so excited.

Although the LED display is only used once at the opening ceremony, there will definitely be many tests before that, so the battery used must be a secondary battery.

Whether it is a battery or other secondary batteries, Chaowei Power Supply Co., Ltd. is a leader in the industry. If there is any company in China that can solve the problem of LED display function this time, it can only be Chaowei power supply, and there can be no other company.

"Impossible, a six-fold increase, it's a fool's dream!"

This is the first sentence after the boss of Chaowei Power got the news.

Yes, he just thinks it's impossible, with the current state of battery technology, it is impossible to improve the energy density of batteries, which is a world problem.

In this case, if you want to reduce the energy-to-weight ratio of the battery, you can only find two ways to increase the weight of the cathode active material and reduce the weight of the battery pack accessories.

And to start from these two aspects, so that the battery performance is six times higher, it is indeed a fool's dream, so from a professional's point of view, what the boss of Chaowei Power said is not unreasonable.

Zhang Yimou is a director, not engaged in scientific research, so how can Ren Chaowei explain it, he didn't understand the difficulty of it.

Chaowei's side didn't believe that Star Technology could have this kind of technology, and Zhang Yimou wasn't sure if Chaowei's statement was true or false, so there was today's meeting.

In Zhang Yimou's room, because of Le Yuan's words, the atmosphere was a little awkward for a while.

Mediterranean smiled and said, "Since this is the case, then I will say it directly, Mr. Le, your company said that it can provide a secondary battery with six times higher performance on the original basis, I don't know if Mr. Le, you are wrong?"

This is equivalent to pointing at Leyuan's nose and questioning the strength of the Star Company, but Leyuan didn't react at all, neither anger nor disdain, he shook his head lightly, "I didn't say it wrong, and you didn't hear it wrong." ”

Leyuan's attitude made Mediterranean very unhappy, although he knew that Leyuan was the general manager of the Star Company, but in the field of batteries, they Chaowei Power Company was the boss.

He stared at Le Yuan and said slowly, "Mr. Le, you may not know much about the technology of batteries, I don't mind popularizing it for you, a battery, the weight of the electrolyte alone will account for more than ten percent, plus the shell, external electrodes and other auxiliary materials, the total weight will be accounted for nearly half, and in this half......"

The Mediterranean talked eloquently, and from time to time he said a few chemical formulas, which made people feel unclear, as if this was not a business meeting, but a chemistry lecture on high school knowledge.

The more he talked, the more excited he became, and the other three could only look at him "dumbfounded", at least, it was his own feeling.

Scumbags, tremble, this is the power of science.

However, the fact is that Zhang Yimou and Yu Ping are not interested in technology, and they are both absent-mindedly thinking about their own affairs.

Leyuan, on the other hand, felt that the things he said were too simple and uninteresting. In Leyuan's eyes, Mediterranean is more like a schoolboy who came to show off to him.

The knowledge popularization of the battery lasted for ten minutes, and Zhang Yimou finally couldn't help but say, "Mr. Lin, these things you said are too profound, can you say it simply." ”

Mediterranean wanted to continue, but since Zhang Yimou had spoken, he could only conclude, "In other words, it is impossible to improve the performance by six times that Mr. Le just said, which is out of common sense." ”

After listening to Mediterranean's words, Zhang Yimou turned his gaze to Leyuan, "Mr. Le, what Mr. Lin said, what do you think?"

Leyuan put down the water cup and said slowly, "As far as I know, your company is preparing to use nickel-cadmium batteries this time." ”

Mediterranean was stunned for a moment, and then smiled, "Of course, this is not difficult to guess, considering a series of problems that may be encountered during the opening ceremony, such as stampede and weather, we choose to use nickel-cadmium batteries, because nickel-cadmium batteries not only have high stability, safety and consistency, but also have a relatively considerable weight specific capacity." ”

Leyuan nodded, "It is true that the stability of nickel-cadmium batteries is better than that of other batteries, and it is also considerable in terms of weight and capacity, but its safety is not the best, and the specific capacity is not the highest, and it has no characteristics." ”

Mediterranean laughed disdainfully, "So, this time the Star Company is going to choose other batteries, for example, lithium-ion batteries? ”

It is true that lithium-ion batteries, although they have an advantage in terms of weight ratio and capacity, cannot increase the performance by a factor of six in any case.

"Actually, yes. ”

Le Yuan said this sentence expressionlessly, but it felt fantastical to the ears of the Mediterranean.

He feels like someone is telling him that someone can run 100 kilometers in an hour on a bicycle, and everyone knows that it's impossible.

"Impossible!"

He thought so, and blurted out at the same time.

Leyuan looked at his excited appearance and said with a smile, "What's impossible, just take the 18650 model battery, the capacity was 1.3a.h in 95 years, and it reached 2.6 in 05 years, and last year, Panasonic also announced the development of 3.0 18650 model batteries." You should know all of this, so what's impossible about this. ”

Of course, Leyuan knew about this Mediterranean, but he still couldn't convince him, he argued, "But the 3.0 18650 can't reach six times that of nickel-cadmium batteries, this is the latest technology of Panasonic, and it is impossible for your Star Company to surpass theirs." ”

He swore by it, but Leyuan smiled and said, "Why not, why can't our Star Company surpass them? Our company has the world's smallest pitch LED display, and we also have the world's best smart phones, why can't we have a lithium-ion battery that is only a little better than Panasonic?"

Leyuan's words made the Mediterranean speechless, yes, why not, Star Company is a leader in other industries, why can't it continue the miracle in the battery industry?

But he still couldn't figure it out, he shouted: "No, no matter how high the capacity of your lithium-ion battery is, it can't be used, the safety performance is too low, if it rains in those days, as long as there is a drop of water seeping into it, there will be unimaginable consequences." Even if it doesn't rain, if you step on ......"

"This doesn't bother your company, our company naturally has our own methods. Speaking of this, Le Yuan stood up with a smile, "Director Zhang, I still have some things to go back to deal with first, so I won't bother here." ”
