For the gift, start research and development of graphene batteries

Chapter 70 High Density Carrier Design Scheme
"Here, this is the Pei Yuan Pill for you."

While talking, Jiang Ming handed the vial containing Peiyuan Pill to Qing Shuiyan.After Qingshuiyan opened it, he also smiled happily when he saw the round pills inside.

"These 5 are what I need now, and I may buy them later. If you have any extra, keep them for me."

Qing Shuiyan said so.

"no problem."

Jiang Ming said bluntly, even if I don't eat it myself, I must guarantee the supply for you.

"But let me tell you in advance that if there is a problem with eating, I don't care."

This point has to be said in advance, Peiyuan Dan Jiangming is fine after eating, but it does not mean that other people are fine.

"Uh, okay!"

Qing Shuiyan hesitated for a moment, then said.

Jiang Ming saw Qing Shuiyan's hesitation and wanted to say something more, but in the end he couldn't.

After getting what she wanted, Qing Shuiyan also calmed down a lot, and left after not staying in Jiang Lin for long.

But before leaving, Qing Shuiyan had to add Jiang Ming's information, saying that she would contact Jiang Ming more in the future.For such a big customer, Jiang Ming was naturally extremely happy.

The endorsement of Yufufan was settled, and Jiang Ming felt much smoother. Next, he still had to work on the carbon-based battery.

Recently, with the shortage of lithium carbonate materials, the entire lithium battery market is becoming more and more volatile.

Some relatively large companies can still buy high-priced lithium carbonate materials, and they can barely stabilize the market by raising the selling price of end products.

But for many small and medium-sized enterprises, it is more dangerous.

In themselves, these small and medium-sized enterprises make low-end products and are very sensitive to prices.A product itself may only cost tens of dollars, and the cost of the lithium battery used in it is now close to the price of the entire product. This kind of business is simply impossible.

Xia country's local products can no longer be produced, but the demand in the entire market has not decreased.In this case, merchants can only supplement by purchasing from abroad.

This method of relying on outsourcing may be okay in the short term, but over time, it will seriously dampen the enthusiasm of Xia Guo's enterprises.The ecological chain of related industries will suffer a devastating blow.

In the future, it is possible that this industry will be over.

Many people may say, it's over when it's over, I have money to buy it, and this little money is affordable.

But the reality is that in many cases, you can't buy it with money.

Under normal circumstances, there is no problem with the supply, but once there is a problem with the market supply, the bottleneck will appear.

It is extremely uncomfortable when this happens.It is ordinary consumers who are ultimately hurt.

This is the current situation in the lithium battery industry. The key materials are basically outsourced, and now they are restricted by others, which is very difficult.

Mr. Wang Mingyang, these days, has been on a business trip to find a way out for Xiaguo's small and medium-sized new energy companies and policies for the entire industry.

Of course, it is one aspect to transform many small and medium-sized enterprises, and more importantly, the research and development of carbon-based batteries.

The research and development of carbon-based batteries has reached the most critical moment, and most manufacturers have already produced samples.The next step of the plan is to transport these samples to the cell manufacturer, and then assemble them into samples.

Although according to Jiang Ming's idea, there is no problem with the idea of ​​carbon-based batteries, but such a large-scale production is the first one.

It is not known what the performance of the batteries produced is.

But no matter what, the use of lithium carbonate materials in new batteries has dropped to the lowest level.

While Xia Guo's engineers were intensively designing and developing carbon-based batteries, the Lithium Battery Summit was being held in full swing in Molun Pavilion.

In previous years, Xia Guo's companies would also arrange for people to participate, but for some reason, this year's Lithium Battery Summit did not include Xia Guo's companies.

Rumor has it that no lithium battery companies from Xia Guo were invited to this year’s Lithium Battery Summit.

When the news came out, Xia Guo's new energy industry was in an uproar.

Although Xiaguo's new energy industry has been severely damaged due to raw material problems, Xiaguo is the largest new energy vehicle market for Aquabluestar after all, and the Lithium Battery Summit is incomplete without the participation of Xiaguo enterprises.

Jiang Ming was very angry when he saw the message.

Now it seems that other companies are really bullying people too much. Not only are they restricting the purchase of lithium carbonate materials in Xiaguo, but now they are not even invited to participate in industry summits, which is simply too much.

Regarding this, Jiang Ming asked Professor Wang Mingyang in private, but Professor Wang Mingyang gave different opinions.

"What, we voluntarily refused to participate?"

Jiang Ming was extremely surprised when he heard the news.

"Yes, it is the decision of our industry association."

"No, even though we are stuck, it's better to attend such a global meeting, right?"

Jiang Ming expressed his views.

"Participate, why do you want to participate? Is it to make our company look down upon in the past!"

Mr. Wang Mingyang was very excited.

"Hmph, do you think that the restrictions on Xiaguo's new energy materials are just a decision of a certain company? This is a joint effort by many multinational companies to fight against Xiaguo's new energy companies."

Wang Mingyang said.

"Among them, there are LJ Company and four-star company. Shout out, Buston, which one is not a well-known company. If they can't compete, they will take this kind of measures to force Xia Guo's company to release the patent of graphene battery. How can there be such a thing?" Good thing."

Hearing Wang Mingyang's words, Jiang Ming finally understood.

Other lithium battery giants want the patent of Xiaguo's new battery, and let Xiaguo enterprises license it for free or at a very small cost.Xia Guo's companies were naturally unwilling to give up food, and the conflict between the two naturally arose.

To unite to restrict raw materials is also to commit Xia Guo's enterprises.

After all, they have played this kind of thing a lot.

In many fields, relying on this method, they have successfully opened up the local market and destroyed the local production enterprises.

In the end, they became the exporting country of bulk commodities, while the buyer became the exporting country of raw materials instead.

All the profits in this process were earned by them.Raw material exporting countries can only export the lowest-end raw materials, and basically have no hope of making a comeback.

Just understand this point, this time, the New Energy Industry Association, seize this opportunity, and prepare to fight to the end with foreign lithium battery giants.

Either Xia Guo's lithium battery industry is finished, or the entire lithium battery industry will be completely reshuffled.

It was with this determination that the two sides kept fighting.

International lithium battery giants are also wary of Xia Guo New Energy Association's various actions.

According to Xia Guo's actions, Xia Guo's industry should be developing a brand new battery to counter the blockade of raw materials by lithium battery giants.

Just the new battery, is it so well developed?
No matter how powerful the performance is and how cheap the battery is, lithium batteries must always be made of lithium carbonate. Without raw materials, Xia Guo can't play any tricks.

This is the judgment of the lithium battery giants on the industry, and it is also their confidence.

It's just that they never imagined that the carbon-based batteries under development have basically got rid of the shackles of lithium carbonate materials, and their blockade is destined to be empty.

The purpose of holding the Lithium Battery Summit this time is also to eliminate Xia Guo's enterprises at the meeting.

It's just that Wang Mingyang and the others didn't arrange people to participate at all, which caused the companies that were supposed to show off to feel like gravity was hitting the cotton.

Because the project has reached the mid-to-late stage, there will be a lot of related meetings.

As the deputy chief engineer, he was responsible for the promotion of the entire project, and Jiang Ming had to attend most of the meetings.

"This is the 261 project meeting for carbon-based batteries. The review this time is about the design proposal of the high-density anode carrier fluid submitted by GN Group."

In the project meeting, the host announced the start of the project review meeting.

Afterwards, the technicians of GN Group began to talk about the design of the carrier fluid.

The carrier fluid, which Jiang Ming is very familiar with, is connected to the battery pole piece and used as a channel for the other party to charge and discharge.

In traditional lithium batteries, the carrier fluid of the positive electrode is generally aluminum, and the carrier fluid of the negative electrode is generally nickel sheet.

Generally speaking, if you are not making a high-rate battery, the requirements for the carrier fluid will not be very high. As long as there are no problems with the materials, generally speaking, there will be no problems.

But carbon-based batteries are different. Because the energy density of carbon-based batteries is too high, the discharge current is too large. If the design of the carrier fluid is not good, the internal charge and discharge of the battery will increase. The external performance is that the battery is used Sometimes, the fever is severe.

Therefore, Jiang Ming requested a redesign of the carrier fluid for carbon-based batteries.

The general requirements are: the price is as cheap as possible and the internal resistance is as small as possible.In addition, the welding performance is better.

Even though it is only a small amount of fluid-carrying fluid, the requirements for materials are particularly stringent.

Ordinary companies really don't have the strength to successfully research it.After all, it is difficult to succeed in the research of basic materials without a long-term foundation.

Even, in order to fear that this research would slow down and slow down the progress of the entire project team, Jiang Ming deliberately separated the positive and negative materials and handed them over to two companies for development.

The GN Group is in charge of the research on the negative electrode carrier fluid.

"In order to meet the ultimate requirement of less than 0.01Ω, we added a variety of materials based on vanadium compounds to the traditional nickel material, and finally met the requirements of the project team."

"After our testing, this alloy has excellent performance and stable quality."

Guan Neng's technicians were talking endlessly, but they didn't see Jiang Ming on the other side at all, and their brows were already frowning.

The performance of the newly developed negative electrode carrier fluid is incredible, but its raw materials are a bit difficult to work with, which does not meet the cheap characteristics that Jiang Ming wants.

"Colleague, please interrupt me. I wonder if you know the price per ton of alumite?"

"Forehead"

Hearing Jiang Ming's words, the technician from Guanneng was stunned for a moment and said that the issue of material performance was related to the issue of price.

"It's about 600 yuan/ton."

The technician from Guan Neng was stunned and did not answer, but other colleagues responded.

"The cost of nickel ore is 600 yuan, which is about 100 yuan. The price difference is 5 times, which will inevitably increase the cost of the battery."

Jiang Ming said so.

After hearing Jiang Ming's words, Guan Neng's technical staff's expressions changed and they realized this problem.

"If the high price will only increase the cost of the battery, then whether the materials can be bought is another question."

What, everyone was dumbfounded when they heard Jiang Ming's words.

"As far as I know, the reserves of alum ore in Xia Kingdom are very low, and they basically rely on imports. Once someone gets stuck, it will be another kind of 'lithium carbonate'."

Jiang Ming said slowly.

Geek!

Hearing Jiang Ming's words, the others did not respond, but Wang Mingyang was aware of the problem.

Other technicians only know that they need to develop a high-performance battery and a brand-new system, but they don't understand the significance of doing so.

But Wang Mingyang knows that this is to circumvent the limitation of lithium carbonate material, and it is essentially to solve the stuck neck situation. It cannot solve the old stuck neck situation, and other materials are stuck again, which is more troublesome.

Aware of this problem, Wang Mingyang couldn't sit still. This is a big problem. He didn't notice this problem during the previous review.

It seems that all plans need to be re-examined, and the issue of localization of materials should be given top priority.Even if the performance is slightly worse, it doesn't matter, it's better than not having the material.

With the arrangement of Wang Mingyang, the research on the localization of materials for carbon-based batteries has been vigorously launched.

Seeing this, Jiang Ming felt emotional for a while. With such a thing, it seems that it will take some time for the carbon-based battery to go offline.

After all, the carbon-based battery was designed by Jiang Ming, and Jiang Ming is quite familiar with the progress of the entire project.

According to the current materials collected by various project teams, there will not be many major problems, and there are still some minor problems, but they will not affect the advancement of the entire project.

Jiang Ming's only concern now is the safety of the battery.This is also the pain point of new energy batteries.

In fact, with the promotion of Xiaguo's new energy vehicles, battery fire is an unavoidable topic.

Frequent fire accidents are harmful to the entire industry, and they are also a problem that lithium battery technicians have been seeking to solve.

General lithium batteries will have this fire problem, especially for carbon-based batteries.

And because the energy density of carbon-based batteries is too high, once they catch fire, it is very likely to cause great losses, which may exceed the value of the batteries themselves.

Therefore, for high-density chemical batteries, Jiang Ming feels that he should remain in awe.

Although carbon-based batteries have made many improvements in battery thermal runaway.Regardless of the overall structure of the battery core, the composition of the electrolyte, or the selection of the separator, a set of combinations can minimize the risk of fire.

But for a new battery, acupuncture experiments are still needed to verify the safety of the battery.

Although Jiang Ming believed that there would be no problem with the design idea, Jiang Ming didn't have a clue about the finished product made by the cooperation of so many units before it really took shape.

Jiang Ming is waiting, waiting for the battery to be formed.
