"Want to get away with it?" This is Zhang Wenkai's thoughts, since the American empire has been eager to get this technology, what kind of play is this, even if you are not satisfied, you can lower the price! Why suddenly put on the appearance of rejecting people thousands of miles away. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

In fact, Zhang Wenkai doesn't know much about the economy of the American Empire, but Duwei knows everything.

If there is no economic crisis, the policy of 'hiding wealth from the people' is definitely the object of envy, but once an economic crisis occurs, then it will immediately develop in the opposite direction, and it is extremely miserable.

And 'hiding wealth in the country' means that the state can regulate and control at all times, so that the economy can tend to stabilize.

Many people may say that economic crises cannot always occur, and in summary, most of the time there is no economic crisis!

This is true, but everyone knows the nature of capitalism, and it is prone to economic crises.

The current debt of the US empire is out of control, before Obama took office, the US empire had a debt of ten trillion dollars, and now a few years later, the total debt has reached 19 trillion, which means that the debt will increase by 100 million every hour.

Coupled with the transnational business of various companies in China, the business of the US empire has been reduced.

Today, 51 oil and gas companies have collapsed, and there has been a "wave of closures" in the retail industry, so it can be said that the US empire will face another economic crisis.

So, now the US empire simply simply does not have the power to buy inconsequential things.

Even graphene battery technology is not good, and it will not be effective in the short term in terms of revenue.

The guard sat quietly like this, his eyelids drooping, and he seemed to be sure that Zhang Wenkai would lower the price.

"And what price can you give?" Zhang Wenkai frowned, if the US empire sincerely lowered the price, it would be very embarrassing.

If it's too low, there is no room for maneuver, and if it is not good, it will enhance the popularity of the American empire.

"A trillion dollars!" The dumbguard held out a finger.

This price, hearing Zhang Wenkai shake his head, is only equivalent to the price of nearly 6 trillion yuan, due to the influence of Huaxia Xinke, the exchange rate of the US dollar has fallen below the mark of six yuan.

The gap is too big to accept.

You know, contemporary scientists are already predicting that graphene batteries are the key to unlocking the beginning of the energy field, how can this technology that spans the nature of the era be so cheap.

"Mr. Duwei, I advise you to think carefully, if your country really doesn't want to buy it, I plan to ask Soviet Russia and some countries in Europe." Zhang Wenkai has become disillusioned with the American empire, and the former country with deep pockets no longer exists.

"Mr. Zhang, please allow me to think about it."

The guard took out his phone and entered the small room again.

......

An hour later, Zhang Wenkai and the guards clasped their hands, not because they had special habits, but because the business was negotiated.

In the end, the deal was negotiated for $1.9 trillion.

The two parties smiled, and in this smile, Zhang Wenkai hid a trace of coldness.

He is a very kind person, and he never takes the initiative to find trouble with others, even if Yu Jisheng kidnapped Zhou Yuya at the beginning, he has plans to let Ji Sheng go.

However, this does not mean that he has no fire, and now with the growth of strength, the fire is even better than before.

The enmity of the American empire cannot be reconciled, so the only way to fight is to fight.

However, he knew that he could not fight against a country on his own, but he could use other means, as long as the American empire was not without desire, he had a chance.

Graphene battery technology is a great way to do this.

As long as the US empire buys this patent, it has already entered the pit he dug.

Bidding farewell to the guard, Zhang Wenkai returned to the private laboratory, intending to see how the new battery technology is being developed, since the graphene battery has been sold to the American empire, then this new technology will be intensified.

"Sir, this is the latest battery." Xiao Na saw Zhang Wenkai coming, and directly took out a battery and handed it to Zhang Wenkai.

It is slightly cool, and the shape of ordinary lithium batteries is somewhat similar, the only difference is that the surface of the battery is covered with fine holes, which are larger than the eye of the needle.

"Sir, you can call it an air battery."

"It has a better energy density."

Cortana called up the detailed parameters of the air battery.

Zhang Wenkai carefully looked at the projected data and learned that this kind of battery is a battery that uses lithium as the anode and oxygen in the air as the cathode reactant, and its capacity depends on the lithium electrode.

Energy density means it can be used on larger devices.

However, the more Zhang Wenkai looks at it, the more incredible it feels, it seems that the theoretical framework of this battery is completely different from ordinary lithium batteries, and it is even more different from graphene batteries.

Don't look at it as just a small battery, it not only inherits the characteristics of graphene batteries, that is, fast charging, the most important thing is that it does not need to be plugged in to charge.

How do you charge without plugging in? The principle is very simple, lithium releases electrons to become lithium cations, which pass through the electrolyte, react with oxygen in the air, and then go through a series of complex catalytic oxidation methods to achieve the discharge process.

It's not science fiction at all, this concept has been mentioned in many countries, but it is simply not able to develop it because of some fatal flaws.

Now that it has been developed by Xiao Na, it can only be said that Zhang Wenkai should make this money.

Cortana took the battery and put it into a mobile phone, but the phone did not turn on, only to see Cortana, facing the hole on the battery, back and forth, fanning for about ten seconds, Cortana pressed the power button, and the mobile phone screen lit up.

"Why fanning back and forth?" Zhang Wenkai was puzzled.

Xiao Na said with a look of 'you don't understand this': "The battery does not need to be plugged in, it only needs to be in contact with the air to generate current, I fan back and forth, just to accelerate the generation of current..."

"Ten seconds at a time is about three hours of use."

"And this battery can last for two years!"

This result surprised Zhang Wenkai, no need to plug in the back and forth fan, you can have electricity, which is too in line with the characteristics of how fast and good Huaxia is.

Zhang Wenkai took the phone, put his nose on the hole in the battery, and sniffed it gently, without any smell, and touched it with his hand, and there was no excessive temperature.

"Cow!" Zhang Wenkai gave a thumbs up.

"Did he do anyone any harm?"

"There are many harms, but there is no harm to people who have been injected with vaccines against electromagnetic radiation." Cortana called up the dangers of the battery, mainly some electromagnetic radiation.

Zhang Wenkai looked down at this battery, and planned to hold a press conference, believing that after the launch of this battery, it will definitely be able to open an era again. (To be continued.) )
