For the gift, start research and development of graphene batteries

Chapter 43 Showdown, I am the developer of graphene batteries

Forget it, settle in as you come, no one said you can't wear casual clothes, no matter what they do.

Suddenly, Jiang Ming figured it out.The more you think, the more you are bound.

Wu Zonghong dressed so formally, and he didn't see how he was treated.

Besides, if you give them a report by yourself, it is equivalent to passing on karma and teaching the way. Why should you accept them?

Thinking of this, Jiang Ming felt that it didn't matter.

Unknowingly, Jiang Ming's mentality changed, becoming less serious.

"Cough cough."

Jiang Ming coughed twice, motioning for everyone to quiet down.

“What I’m going to tell you today is the future development direction of graphene batteries, which is also the direction of future improvements.”

Jiang Ming said so.

"Wait a minute, I want to ask, before I talk about the future development direction, can I explain the graphene battery itself."

It stands to reason that you shouldn't ask questions at this time, but who made Liu Changqing in the second row, a boss, have this right.

As for everyone, seeing Liu Changqing's exit, they felt a sense of relief.

At this time, Jiang Ming came up and talked about the future development direction, which was a bit high-end. What everyone actually wanted to know was the research process of graphene itself.

Therefore, everyone couldn't help but cast a supportive look at Liu Changqing, and then looked at Jiang Ming eagerly.

As for Liu Changqing, he wasn't thinking of everyone, he was trying to embarrass Jiang Ming.

You must know that Jiang Ming's topic on the future development direction of graphene batteries is really too big, and it can be entered or defended.

You can talk about specific details, or you can talk about theory.

Liu Changqing was afraid that Jiang Ming would take advantage of his loopholes, so he reversed the direction ahead of time.

"This is a basic issue. Everyone understands that there is no need to waste time here."

Jiang Ming responded without thinking about it.

After all, graphene batteries have been around for so long, and everyone has a certain understanding of them. It’s not interesting to use graphene batteries themselves. Jiang Ming is going to talk about high-end ones.

Hearing Jiang Ming's words, Liu Changqing was speechless.

What is a basic problem, what is a waste of time, these words seem to be insulting everyone's IQ.

Yes, Wang Mingyang, the guy you are looking for has his own tricks. He knows how to play this kind of trick.

Liu Changqing looked at Wang Mingyang and thought in his heart.

Looking at Liu Changqing's eyes, how could Wang Mingyang not know, but at this time, it's useless to say more, it still depends on Jiang Ming's performance.

Therefore, Wang Mingyang was too lazy to speak.

"It's a basic question, but there are many people from other industries on site. I think it's necessary to explain it clearly to everyone."

Liu Changming continued.

Pretend, pretend again, see if I don't expose you today, let you show your true colors.

"Okay then, let's review this basic question, I hope you don't feel like it's a waste of time."

Jiang Ming looked at the audience and thought so.

Why don’t we understand such basic issues?

Everyone thought of this in their hearts, but they still shook their heads, signaling not to waste time. Suddenly, everyone had such a tacit understanding, waiting for Jiang Ming to make a fool of himself.

"We all know that lithium-ion batteries, also known as rocking chair batteries, generate current as lithium ions shuttle back and forth between the positive and negative electrodes, which in turn leads to the concept of charging and discharging."

Jiang Ming said.

We understand this, let’s talk about the key points!
Everyone has a strong thirst for knowledge and is waiting for Jiang Ming to continue editing.

"Therefore, increasing the concentration of lithium ions and establishing corresponding channels are the focus of current research."

"The traditional theory believes that as long as the concentration of lithium ions is increased to a sufficient level, its corresponding energy density will increase accordingly. And then it is because the concentration of lithium ions is not enough that the energy density of the battery cannot be increased."

Isn't it, what's new?
"This view is wrong. Increasing the concentration of lithium ions will increase the upper limit of the energy density of the battery, but the essential problem is that the ability of the negative electrode material to absorb lithium ions has not improved."

Jiang Ming said slowly.

After hearing Jiang Ming's words, everyone couldn't help but think, is there any truth to this?
According to the current research, the ions that the negative electrode can absorb are actually very high. If it is higher, the battery will be properly overcharged.

"Therefore, based on this theory, improving the negative electrode material to allow it to receive more lithium ions can greatly increase the energy density of the battery."

Jiang Ming explained.

"Next, let's talk about the future"

Having finished explaining, Jiang Ming continued the previous topic.

"Wait a minute, I have another question, how to improve the negative electrode material to achieve this effect?"

Hearing that Jiang Ming finished speaking quickly, and then crossed the question, Liu Changqing hurriedly stopped.

Seeing Liu Changqing speaking, everyone couldn't help but feel grateful. They just got to the point, how could they pass it by?

Compared with everyone's eagerly looking forward to it, Guo Zhen and Baineng's chairman in the last row were sweating profusely.

Good guy, what Jiang Ming is talking about is the unique technology of Baineng Company, so it will be prostituted by everyone for nothing. After everyone has mastered it, what else will they do with Baineng.

After all, prostitution for free is immoral, no matter what industry it is.

But at this time, the two of them couldn't get in the conversation, so they couldn't yell loudly and tell Jiang Ming not to talk.

"In terms of improving anode materials, it's pretty simple."

Speaking of this, Jiang Ming stopped and then waved to everyone.

Everyone realized something and immediately applauded enthusiastically.

Good guy, after listening for a long time, I finally got to the point.Although I don't know who this Jiang Ming is, but judging by his confident appearance, and in front of so many people, he must be right.

The applause that does not require money is soaring.

Seeing everyone applauding, Jiang Ming was dumbfounded, and thought that you have misunderstood it, do I want applause? I want to say that it is inconvenient to say about the improvement of the negative electrode material of Gu Anu.

These people are stupid!
"We don't need to talk about simple things, let's continue."

Jiang Ming prepared to paddle across.

"Wait a minute, Mr. Jiang, let's talk about it carefully."

Liu Changqing spoke again, and everyone was grateful for a while.

"It's like this. The improvement process of negative electrode materials is a chargeable item. If you need it, please contact Baineng Company."

Jiang Ming said.

amount.

When they heard about Jiang Ming's charging items, everyone was a little bit angry. Good guy, after chasing for a long time, they gave everyone such a result. It can't be justified.

President Guo and Chairman Baineng also breathed a sigh of relief when they heard Jiang Ming's words.

He said in his heart that this kid Jiang Ming still knows how to keep secrets, and he still needs to repair the relationship between the two in the future.

Others are not happy, there is a feeling of being played.At the same time, everyone had doubts in their hearts. This kid will not know anything, so let's talk nonsense here.

Mysterious, either guilty conscience or nonsense.

Moreover, no one knew where this kid came from, so how could they be sure that what he said was correct.

What the boy said earlier sounded reasonable at first, but after careful consideration, something was wrong.

After all, the theory mentioned by Jiang Ming has not been verified before.

Thinking of this, everyone couldn't sit still. Could it be that everyone had been teased by this kid?Where did the industry association find such a deceptive person?

"If you don't know, you don't know. How can there be so many reasons? How can anyone be a guest speaker on stage these days."

Someone spoke again, and it could be seen that he was very angry at Jiang Ming's secretiveness.

That's right, that's right, what are you pretending to be, if you don't know, you just don't know, pretending blindly here, what is this kid's identity.

The crowd was passionate and noisy, which made Jiang Ming unable to get off the stage and prepared to bombard Jiang Ming.

Hearing the words from the audience, Jiang Ming was also a little speechless.

It seems that I overestimated the abilities of these people, can't I see such obvious hints?

Graphene batteries technically belong to Baineng Company. Jiang Ming can talk about graphene to the outside world, but when it comes to the core, Jiang Ming has no right to talk about it.

I have to say, this is the core technology of Baineng, am I not entitled to say it?
I have pointed out the way for you, contact Baineng Company!
Of course, Jiang Ming suspected that someone was instigating this, and Jiang Ming couldn't bear it, so he took the initiative to speak out.

Regarding this, Jiang Ming could only hehe.

Since you doubt my skills and my identity, stop pretending and prepare for a showdown.

Jiang Ming has already made such preparations.

“He is the developer of graphene batteries.”

At this time, Bai Yunsheng, the chairman of Baineng, spoke.

what!
Hearing Bai Yunsheng's words, everyone was shocked. Jiang Ming turned out to be the developer of graphene batteries. What a shock.

Since Jiang Ming is the developer, what the hell is the former chief technical expert? How can a company have two groups of people, and explain graphene batteries at the same meeting.

I'm afraid there is some inside story in it!

Seeing Bai Yunsheng standing up, Jiang Ming was a little confused, thinking who is this guy, and how did he know that he is the developer of graphene batteries.

You know, few people know about Jiang Ming's research and development of graphene batteries.

But when he saw the person next to Bai Yunsheng, Jiang Ming understood that next to him was Guo Zhen, Mr. Guo.

The one who can accompany Mr. Guo must be the top management of Baineng.If you think about it this way, it's not surprising.

Those who didn't know wanted to question Bai Yunsheng's words, but the people around him who knew about it hurriedly told him that this person was the chairman of Baineng, and what he said about graphene batteries must have weight.

All of a sudden, the way everyone looked at Jiang Ming changed.

Good guy, the developer of graphene batteries, this name is loud enough.The batteries are all researched by him, and the process principle is very clear.

Everyone can even understand what Jiang Ming said just now that this is the basic content.

After all, graphene batteries have been developed and mass-produced, so there is really no need to do anything else.The focus of the follow-up will definitely be application improvement.

High, this is a master, compared with others, it is simply not up to the grade.

Seeing the sudden reversal of everyone's attitude towards Jiang Ming, Wang Mingyang's hanging heart instantly fell to the ground.

Afterwards, Wang Mingyang looked at the waiters with a grin.

All of a sudden, everyone was angry and hated.

But everyone had to admire Wang Mingyang's method, and even got to know the developer of the graphene battery. No wonder such an unknown person as Jiang Ming was invited to speak on stage.

Fortunately, Mr. Wang Mingyang still acted worried, and everyone couldn't help laughing.

God has a lesson, Mr. Wang Mingyang is really worried about Jiang Minglu's timidity.

Seeing everyone staring at him eagerly, Jiang Ming felt relieved for a while. This is like talking about cross talk, and the effect of speaking by himself is not good, the key is to be praised by others.

"We continue to talk about the future development of graphene batteries."

Jiang Ming continued.

"Although the performance of existing graphene batteries is much better than that of ordinary lithium batteries, they still cannot exert all the performance of graphene batteries. How to put it, they only exert one-fifth of the performance at most."

Jiang Ming concluded.

Hearing Jiang Ming's words, the scene exploded.

We must know that the current graphene battery has an energy density of 600Wh/kg, but the result is less than one-fifth of the performance of the graphene battery.

If they didn't know that Jiang Ming was the developer of graphene batteries before, everyone would not have sprayed Jiang Ming to death, but now, with the title of developer, everyone still maintained a certain degree of restraint.

But from the bottom of their hearts, everyone still didn't believe it.

Even Mr. Wang Mingyang's face was full of disbelief.

"Why, don't believe it?"

Jiang Ming asked.

Well, it’s not that I don’t believe it, it’s that I really don’t believe it!
"The existing graphene battery can only be regarded as an upgraded product of the traditional lithium-ion battery. The improvement of its performance depends on the improvement of the negative electrode material. You are all leaders in the industry, and you should know the role of the negative electrode material in the battery."

Indeed, the role of negative electrode materials in lithium-ion batteries is not as great as imagined.

The most critical thing is the positive electrode material and electrolyte, which are the key research points of major manufacturers.

Most of the existing improvements are based on cathode materials.For Baineng's graphene batteries, this kind of improvement centered on negative electrode materials is indeed rare.

"The positive electrode material is the key point, and the electrolyte is also indispensable. Even the tabs and shells need to be changed."

"After calculation, the energy density of the complete version of the graphene battery is expected to reach 2500Wh/kg. According to the existing battery pack volume, the cruising range on a single charge is expected to reach 5000km."

"At that time, charging for 5 minutes and lasting for a month will not be a dream!"

Speaking of this, Jiang Ming became excited.

This is a power battery, not a digital battery. It is of great significance to be able to achieve this level.

These figures make me feel excited when I think about them. If they can be realized, then there will really be no fuel vehicles in the future.

And not only the new energy industry, but also the traditional engine-using industries will also face great challenges.

Who doesn't love a device that can go months without a charge.

Moreover, the energy consumption ratio of general electricity consumption is relatively low. If electricity is used, it is equivalent to saving costs.

It won't be obvious for a day or two, but over the years, the cost is very considerable.
