Rebirth Technology Power

Chapter 15 The Birth of Li-air Battery
Bragging and farting for a while.

The two chatted for half an hour before ending the chat.

Cai Jin was deep in thought at this time.

There are only one class of their majors, a total of 30 people, from all over the world, and he is the only one in the entire Fujian Province!
Although the number of people is small, each one is quite good.

As a new major and a key major of Southeast University, the school has invested a lot of resources in this major, and the faculty is very strong.

Zhou Xinghuang, he has no way to recruit him.

But for others, it is not impossible.

He is short of talents now, if he can recruit one in the class, that is a profit.

If you can recruit two, you will make a lot of money!

Cai Jin compiled a recruitment notice and posted it in the group, asking interested students to contact him.

Let 'Benben' move in the sea, dug a hole on the beach, there is some water, 'Benben' catches seafood, he will come out and put the seafood in the hole.

During this period of time, Cai Jin has imported all the information that humans know about the creatures in the sea into the information database of 'Benben'. When 'Benben' is in the sea, it will be automatically identified and compared with the information database one by one.

Now it can't afford to provoke it, and 'Benben' won't provoke it either.

Otherwise, Cai Jin would not even have time to cry when 'Ben Ben' was buried in the sea.

Cai Jin looked at the phone happily while blowing the sea breeze.

He issued a recruitment notice, and some classmates really approached him.

He offered his classmates an annual salary of 15 for the first year, including food and housing!
This is already a high salary for a fresh graduate.

So some students were moved.

Cai Jin didn't fool them either, he was still able to afford this annual salary, and he even promised a year-end bonus.

Of course, Cai Jin also explained to them that the company is located in the countryside of his hometown, not in the city.

After an hour, three classmates promised to come to the company after May Day.

"By the way, since classmates can recruit, why can't fellow villagers!?" Cai Jin's thoughts suddenly opened.

Their school has a qq group and a wechat group for the hometown association. Although the group will be more active after the beginning of school, everyone will be diving later, or someone will post a bargain or post an advertisement .

Cai Jin posted the recruitment notice in the QQ group and WeChat group, and then each sent a pack of red envelopes.

Cai Jin knows that the best way to get people not to dive is to give red envelopes, and these divers are the most active in grabbing red envelopes.

Sure enough, the red envelopes had just been sent out, and group members grabbed the red envelopes one after another.

Cai Jin reissued the recruitment notice again.

"Drip drip~~"

Cai Jin's WeChat and QQ immediately had several applications to add friends, and Cai Jin passed them one by one.

Cai Jin was very happy, if he could successfully recruit one, he would earn one!
Among them, in addition to fresh graduates, there are also people with work experience.

There are communication and information systems, signal and information processing, circuits and systems, electromagnetic fields and microwave technology, which belong to information science and engineering.

There are also law majors!
Of course, there are automation majors, as well as computer majors, materials science and engineering majors.

All of a sudden, Cai Jin recruited 20 people, of which 8 were fresh graduates and 12 had work experience, all of whom were from various places in Fujian Province.

Cai Jin directly set up a WeChat group chat and pulled them all into it.

After chatting for more than an hour, Cai Jin took a look. Benben had gone ashore again, checked the battery, and found that there was still some battery.

Look at the puddle again, the puddle is already full of seafood.

Cat's-eye snails, conch, sea urchins, blue and white crabs, red sturgeon, sea bass. There is even a lobster about a catty!

Cai Jin took out the red wooden bucket from the car, and put the seafood in the puddle into the bucket one by one, feeling very happy.

Since 'Benben' evolved, he can enter the sea. He comes to the beach once a day, and there is no shortage of fresh seafood.

Seafood, as long as it is fresh and cooked simply, is delicious.

When Cai Jin returned home, he took down the barrel and gave it to his mother to handle.

He took Benben upstairs to charge Benben.

He is in the group, answering some questions.

Half an hour later, Cai Jin put his hand on 'Benben'.

[Item: Advanced C Intelligent Mechanical Dog]

[Experience value: 200000/1000000]

【Optimization point: 30.5】

Cai Jin glanced at the system panel.

Now 'Benben' is already a high-level C intelligent mechanical dog. At this point, if you want to upgrade, you need to reach 100 million experience points.

Therefore, Cai Jin chose to use optimization points to improve without hesitation.

He put all the optimization points on the battery. The current battery is an all-solid-state battery. Before the propeller is not used, the Benben's battery life is 24 hours.Using propellers in the sea, the endurance is only four hours.

So he put all 30 optimization points on the battery.

One after another shimmers flicker.

Cai Jin was shocked suddenly.

[Item: Advanced C Intelligent Mechanical Dog]

[Experience value: 200000/1000000]

[Battery: All-solid-state battery → lithium-sulfur battery → lithium-air battery]

【Optimization point: 0.5】

Cai Jin gasped.

Thirty optimizations have actually optimized the energy from all-solid-state batteries to lithium-air batteries.

The energy density of solid-state batteries can easily reach 300-400Wh/kg, the theoretical energy density can reach 700Wh/kg, and the lithium-sulfur battery can reach 2600Wh/kg.

And the lithium-air battery can reach 3500Wh/kg!

This means that the theoretical energy density of lithium-air batteries is five times that of solid-state batteries.

Before that, the 'stupid' solid-state batteries have not yet reached the theoretical energy density.

Now, it has reached the theoretical density of a lithium-air battery. With the same battery volume, the stupid 'endurance' is directly increased by ten times!
That is to say, with a full charge, without using propellers, the 'Benben' has an astonishing 240 hours of battery life, which means charging once every ten days.When in the water, it can last for 40 hours, which is close to 2 days!
This time, the short board of 'stupid' is directly solved, and the battery is no longer a short board of 'stupid'.

Cai Jin clicked his tongue.

He still remembers that when they were in class, their teacher talked about batteries, thinking that in the next 5 to 10 years, solid-state batteries and lithium-sulfur batteries will make breakthroughs and be used in commercial applications. In 10 to 20 years, lithium-air batteries are expected to succeed!

But now, this technology is in his hands.

Cai Jin couldn't resist kissing 'Benben', it was an inexhaustible treasure.

It's just that although the seawater on 'Benben' has dried up, the salt is still there.

Salty!
Cai Jin hugged 'Benben' and smiled foolishly.

The current 'stupid' is too perverted!

It can be said that if he has a thorough understanding of battery technology, such as all-solid-state batteries, lithium-sulfur batteries, and lithium-air batteries, he can easily become a new energy giant, and those overseas giants who invest heavily in new energy batteries will be in vain!
These three batteries, any kind of technology, the value will never be less than [-] billion!

And the market size of each of these batteries is trillions.

All-solid-state batteries can directly allow new energy vehicles to easily go from a hundred miles to a thousand miles.
