According to He Tianqiang, copper is actually not a new material.

In general, if graphene powder is added to copper metal, the conductivity of copper wire will also be improved. Of course, this improvement is not huge.

However, if a single layer of graphene is spirally wound with a copper film to form a composite material, even if the ratio of graphene to copper is only 1:1000, the carrier velocity and concentration can be increased by hundreds of times compared with a single copper wire.

Theoretically, copper can achieve a current carrying limit of more than 10,000 times that of copper.

This means that the efficiency of electrical energy transmission will be greatly improved, and at this time, the resistance of copper ene is very small, and the loss of power transmission will be greatly reduced, although it cannot reach the lossless transmission of superconductors, but the current carrying capacity is far more than any superconductor on the earth today.

However, it is a pity that copper is not suitable for superconductors, because the temperature threshold for it to become a superconducting state is only a few tens of K, that is, minus 200 degrees Celsius.

But no matter what, judging from the experimental results and material properties, copper is definitely the best material choice for power cables in the future.

You must know that the power loss in Huaxia every year is very huge, and there is no specific statistics on how much, anyway, it must be no less than 100 billion kWh.

Of course, the current black bones do not use it as a transmission cable, but only as an electrical wire for the second charger.

According to He Tianqiang's test results, a 1 square specification of copper made of graphene with a ratio of 1:1000 to copper can carry a maximum current intensity of 1K ampere, and can load 220kw of power at household voltage.

It can already be used as a wire for a second charger, and it is far from finished.

The material is a good material, and it is not difficult to make it, but on the earth, I am afraid that other companies will not be able to make it except for the Black Bone Group.

After all, they don't have the technology to mass-produce graphene.

At present, the two graphene printing devices on the side of the carbon company, with an annual output of 73 tons, can be made into 50,000 tons of copper according to the ratio of 1:1000, and then considering the loss in the production process.

The wire used to make a second charger is more than enough.

Moreover, it is not difficult to make copperene, He Tianqiang is talking about spiral winding, which is actually copper metal and graphene are stacked layer by layer, so that graphene and graphene do not contact into double-layered and multi-layer graphene, and there is no gap in the middle.

After the technology of copper ene was overcome, hundreds of kilograms of copper were made in just three days through the smooth and precise operation of several AI robots in the temporary plant.

And He Tianqiang's side also successfully combined copper ene with second charging technology to create some ultra-high-power second chargers.

The charging time of a mobile phone battery with a capacity of 10,000 mAh has been successfully controlled to about 10 seconds, of course, it can be shorter, but it is not necessary, 10 seconds is short enough.

Even some researchers in the laboratory also suggested that because it is too shocking to fill a 10,000 mAh battery in 10 seconds, it is better to change it to 60 seconds, and everything within 60 seconds is regarded as a technical reserve, wouldn't it be better?

This kind of capitalist wool gathering practice is indeed good, but it is not necessary.

One square specification of one-thousandth of the proportion of copper ene material, can already reach 220kw load power, change 10 seconds to 60 seconds?

The problem of second charging technology was perfectly solved, and two days later, Jiang Bo flew directly to Yanjing.

Yanjing is about to hold a new energy industry conference, he has to go to see, listen to Peng Liguo said, this energy industry conference, not only to hold a conference, but also to exhibit products, tourists and media are very large, is an excellent exposure channel.

Jiang Bo really wanted to know what kind of expression people would look like when they found that 'lithium-air batteries and second charging technology' were combined?

Someone will be shocked, and someone will scoff.

In addition to the matter of the new energy conference, Jiang Bo received a call from Shen Ye yesterday evening, saying that he was about to celebrate his 30th birthday, and hoped that Jiang Bo could go to Yanjing to attend his birthday banquet.

……

In Yanjing in mid-to-late May 2022, the climate is not too hot, but very cool.

At half past three in the afternoon, there were lead-gray clouds overhead, and the sky was gloomy and not very pleasant, and it looked like there would probably be a rain.

Today is the day when Shen Ye held a birthday party, and the address was coincidentally set at the Grand Hyatt Hotel in Yanjing, and the Grand Hyatt Hotel happened to be Jiangbo's industry.

pondered whether Shen Ye should give him a free meal for his birthday today, but after thinking about it, he felt that his family was not short of money, so he stopped this thought.

At the entrance of the lobby downstairs of the Grand Hyatt Hotel, Shen Ye and his new girlfriend Xiaoting were standing there to greet guests.

Seeing Jiang Bo, Shen Ye's eyes lit up, and he hurriedly led his girlfriend forward, and said with a smile: "Lao Jiang, welcome, welcome, I thought you weren't coming." ”

"How come, since I promised you to come, I will definitely arrive, but I came empty-handed, and I didn't bring any gifts, don't you mind?" Jiang Bo said with a smile.

"What kind of gifts to bring, I don't like those here, as long as you can get there, it's enough to give me face!" Shen Ye said, introducing Jiang Bo: "By the way, this is my new girlfriend Xiaoting." Xiaoting, called Brother Jiang. ”

"Hello Brother Jiang. Shen Ye's girlfriend shouted crisply.

"Hello. Jiang Bo glanced at Xiao Ting and bowed slightly.

"You go and sit over there, and I'll talk to Lao Jiang. After Shen Ye broke Xiaoting away, he said to Jiang Bo: "Hey Lao Jiang, I have worked overtime to erect the shelf of the New Future Battery Company, and besides, the old man in the family also knows about my investment with you......"

"Oh, what is your old man's attitude?" Jiang Bo asked with an eyebrow.

"What other attitude can you have? Anyway, I didn't like it, and I was severely reprimanded, and he scolded me for being a waste, alas...... I'm under a lot of pressure to mess with you now, and if I fail this time, I'll be a waste, don't fool me. ”

Shen Ye stared at Jiang Bo and said. Although he shouldn't have said these words, he just couldn't help but want to say them.

Jiang Bo raised his hand and patted his arm, and said with a smile: "Put your heart back in your stomach, the 20 billion you invested this time will double in value in a short time, and after ten years, your Shen Ye's worth will definitely be in the top ten of the domestic rich list, believe me, and be confident." ”

Although Jiang Bo's words were very vain, after listening to them, Shen Ye found that his heart was indeed a lot more settled, and muttered: "Anyway, don't cheat me." ”

Jiang Bo smiled: "If you're really afraid, then let's do it, let's re-settle the contract now, I'll give you 20 billion, and you transfer the 20% of the shares to me, okay?"

"Really?"

"If you want, I can transfer the money to you first. Jiang Bo said as he reached out his phone.

"Oh, don't, don't, I agree. Shen Ye hurriedly reached out and pressed Jiang Bo's arm and said, "I'm just under a lot of pressure and I'm not sure, you understand." ”

Jiang Bo wanted to transfer money so simply, but Shen Ye wouldn't agree.
