At 3:00 p.m. on October 24, Zhou Yu took a China Southern Airlines plane and came to Pengcheng to prepare to participate in the Intelligent Industry Exhibition.

The employees of Xinghuo Technology, led by Yuan Keqing and Lin Yun, transported the equipment of the exhibition by truck as early as two days ago and came to the venue of the Intelligent Industry Exhibition.

He waited in the waiting hall of the airport for a while, and Yuan Keqing drove to meet him.

They drove to the hotel provided by the organizer of the Smart Industry Exhibition.

Yuan Keqing reported on the road: "Mr. Zhou, our company's booths have been arranged, and our company has two booth locations, and graphene chips and graphene batteries are in different exhibition areas.

Lin Yun coordinated with the organizers of the Intelligent Industry Exhibition in advance, with graphene chips and graphene batteries in the new energy exhibition area, and industrial robots in the intelligent robot exhibition area.

The largest and most trafficked exhibition area of the Intelligent Industry Exhibition is the intelligent robot exhibition area. ”

"You guys are doing a really good job, industrial robots are the productivity of the future, we must seize this opportunity to make our company's reputation." Zhou Yu praised.

They checked into the hotel and waited for the opening of the Smart Industry Exhibition.

On October 25th, the 1st Intelligent Industry Exhibition was officially opened.

Zhou Yu came to the exhibition very early, and when the staff set up the booth, he went to other exhibition areas to observe the situation.

He has a clear impression of the intelligent industry exhibition, this is not an exhibition for ordinary people, the purpose of the organizer is to make a professional industrial exhibition.

There are many exhibitors, most of them are industry-related enterprises, and internationally renowned large companies are present, from CNC machine tools to screws.

Zhou Yu returned to the new energy exhibition area and walked to the booth of Xinghuo Technology's graphene chips and graphene batteries.

When Lin Yun negotiated with the exhibition organizer, this booth could be moved to the chip exhibition area or the new energy exhibition area.

Almost without a thought, she moved her booth to the new energy exhibition area.

Because the graphene chip ecosystem has not yet been built, most devices cannot use graphene chips, and graphene battery technology has made a breakthrough that can manufacture large-capacity graphene batteries.

Because of the successful research and development of industrial robots, Xinghuo Precision Manufacturing Company has also improved the production line of graphene batteries at the same time, and the production capacity of graphene batteries can be expanded to more than 1,000 times that of the past.

Choosing to display graphene batteries in the new energy zone is more hopeful of making a name for itself as a Spark Technology.

The Xinghuo Technology booth was directly covered with holographic images, showing the powerful performance of graphene batteries.

Zhou Yu stood at the back of the booth, watching the crowd coming and going, and Lin Yun was responsible for receiving people who came to the booth to inquire.

If someone asks about graphene battery technology, Lin Yun will bring people to Zhou Yu.

Next to the Xingyu Technology booth, Tianqi Lishen, BYD, AFC Energy and other battery companies, they are all staring at the Xinghuo Technology booth.

Graphene batteries were born, and lithium batteries, fuel cells, and photovoltaic cells could not compete with graphene batteries.

If it weren't for the lack of production of Xinghuo Technology and the supply of their own Star Spirit bracelets, they would have given up the high-end market long ago.

Now they are in a bad mood, and the graphene battery officially accepts orders from the outside world, which means that the graphene battery processing technology has made a breakthrough.

Zhou Yu looked at Xinghuo Technology as if he stood out from the crowd, and there was no one around him who could fight.

A man in a suit and leather shoes was brought to Zhou Yu by Lin Yun, and he asked: "I am the manager of the purchasing department of BYD Automobile, is the performance of your graphene battery the same as advertised?" How much is the production? How much does it cost? Sell battery products directly, or sell graphene battery semi-finished products. ”

His voice was not loud, but the exhibition site was quiet, and the booths were close to each other, and the people in the other booths could hear it.

Someone looked at the BYD battery booth and coaxed: "You belong to the same group, they all have to purchase batteries from other companies, tell me your feelings."

The person in charge of the BYD battery booth was so ashamed that his face was flushed, and he shouted: "We are all half a catty, we are all engaged in battery people, graphene battery performance is really excellent, and the strength is not as good as others."

Zhou Yu was not affected at all, and he immediately replied: "Our graphene battery has entered the mass production stage, and now it can be shipped in the next week."

Now the measurement standard of batteries has not been able to keep up with the development of our graphene batteries.

The performance of graphene batteries is indeed as stated in the promotional materials, the energy storage of graphene batteries per cubic decimeter is one kilowatt hour, and its energy loss is 15% in one cycle of charging and discharging.

Each cubic decimeter graphene battery cell is a unit, the price of each unit is 5,000 yuan, the graphene battery can be divided into any size, and our company comes with the technology of processing graphene batteries. ”

When the person in charge of the Tianqi Lishen booth heard this, his worried expression relaxed.

Graphene battery cells are 5,000 yuan per cubic decimeter, which is only a semi-finished product, and a certain process is required to process the finished graphene battery.

The minimum cost of finished graphene batteries per cubic decimeter is 8,000 yuan, which will inevitably be used in high-end equipment such as electric vehicles.

Only the high-end market is lost, which is not very big of an impact on their company.

"Can I bring back some graphene battery samples?" BYD Auto purchasing manager asked.

Zhou Yu picked up a sample of graphene batteries the size of a USB disk, which was packed in a carton, and the contact information of Xinghuo Technology was on the outer packaging of the carton.

"This is a graphene battery sample, if your company is satisfied with the performance of our graphene battery, you can contact us at any time." Zhou Yu handed him the graphene battery carton.

"Then I'll go, hoping that the graphene battery lives up to its name."

The conversation between Zhou Yu and this person soon spread throughout the exhibition, and people came to the graphene battery booth one after another to consult.

Blue Automobile, Tesla Motors, Geely Automobile, General Motors and other companies interested in the development of electric vehicles have come to inquire about the situation of graphene batteries.

Zhou Yu was constantly harassed by repeated questions, and he directly asked Lin Yun to be responsible for explaining.

"Mr. Zhou, there are special guests, and I don't understand the questions they ask." Lin Yun walked over and said.

Zhou Yu walked towards the special guests that Lin Yun said, there were a total of 5 of them, the leader was a middle-aged man around 40 years old with sharp eyes, and the others seemed to be his subordinates, and they were all respectful to him.

"Hello, I'm the person in charge here, do you have any questions to consult?" Zhou Yu asked politely.

The middle-aged man immediately asked: "I have tested your graphene battery, but I didn't expect your graphene battery energy storage to rise again, its performance is already better than diesel, and the charging speed is still very fast."

How safe is your graphene battery, and will it burn and explode when it is subjected to increased pressure. ”

Zhou Yu was a little surprised, he didn't expect this person to have some understanding of graphene batteries, seeing their gestures, Zhou Yu didn't guess wrong, these people belong to scientists from the military research institute.

"Graphene batteries are physical energy storage batteries, which do not undergo chemical reactions, are very safe and will never explode.

Its special carbon crystal structure rotates rapidly when charged, storing electricity through mechanical energy.

Our promotional materials have stated that after the graphene battery is fully charged, it can be left on full charge for a long time, but once it starts to discharge, the energy conversion rate is high within one month, and the energy loss is not high.

But after more than a month of discharge, the amount of electricity stored in the graphene battery will quickly decrease until it is completely empty. Zhou Yu introduced in detail.

"This small flaw is not serious, as long as the graphene battery is formed into an array, the distributed discharge can be solved, give me a graphene battery sample." The middle-aged man happily took the sample.

He secretly said in his heart: "There is a better alternative to Huaxia's new conventional submarine battery, and it may be possible to research excellent pure electric submarines."
