Rebirth 2002: Nano Life

The weapon that Chen Yizhe showed to Zeng Liuqing was actually the graphene lithium battery of Xia Meng Electronics.

In his personal laboratory, Chen Yizhe has actually produced two kinds of graphene batteries.

The first is to add graphene to traditional lithium batteries, just to improve and improve the performance of lithium batteries. This type of battery will not have any subversive effects. This graphene lithium battery is actually a lithium battery. Graphene is only used as a carbon-based negative electrode material, replacing the original graphite in the battery negative electrode. Although it can indeed improve the overall capacity and charging speed of the battery, the improvement effect is relatively It is still limited for another graphene battery. The overall capacity can be increased by 1.5 times, and the charging speed can be increased by more than 6 times. In a sense, compared with the current lithium battery, there has been a big breakthrough.

The second type is a battery of a new system made by Chen Yizhe based on graphene. It is a brand-new series and subversive in performance. Chen Yizhe calls it a "super battery". In fact, the name of the battery is still inaccurate, it should be called "supercapacitor" more precisely. Since it is called a "capacitor", it is simply a physical process to store electric charge, rather than relying on an electrochemical process to store electric charge like a battery.

Both batteries and capacitors are energy storage elements. The difference between the two is that the former stores a lot of electrical energy, the latter stores less, the latter charges faster than the former, and the former can be charged with a large current. Generally, the capacitor is used as an "instant power supply", so the energy provided is not very large, so the electric energy stored by the capacitor is not much.

However, with the development of electronic technology, the capacity of capacitors has become larger and larger, and with the characteristics of capacitors, capacitors will definitely replace batteries in the end. This is Chen Yizhe's personal view.

The current power supply system of Chen Yizhe's villa uses "super capacitors", which can store up to 1.9 million kilowatt-hours of electricity. What is this concept? Electricity consumption for a month in summer.

However, so far, the "super capacitor" in Chen Yizhe's house is still far from sufficient power. The biggest reason is that Chen Yizhe uses a solar energy reaction device. The sunlight absorbed by solar energy is actually very limited, that is, it can only be used for daily use and there is only a little surplus.

For the two kinds of graphene batteries, Chen Yizhe finally came up with the first graphene lithium battery. The main reason is that the first kind is easier to achieve mass production than the second kind.

For "supercapacitors" to be mass-produced, the method that Chen Yizhe can think of is 3D printing technology. If this method is not used, the physical structure inside the capacitor will require a lot of manpower and cost.

However, even if Chen Yizhe uses the first graphene lithium battery, it is several levels higher than the lithium battery on the market, but due to the addition of graphene, the price may be much more expensive than ordinary graphene.

Although it is expensive, Chen Yizhe thinks it is worth it from the point of view of user experience.

After Chen Yizhe left, Zeng Liuqing took the lithium battery that Chen Yizhe handed him, but he was thinking about the meaning of the last sentence the other party said before leaving.

"Mr. Zeng, this is a lithium battery independently developed by our company. It has not yet been launched on the market. I hope you can give some pertinent and valuable opinions after the test on your side." Chen Yizhe said so.

"Could it be that the other party can develop a lithium battery that is more powerful than Panasonic or LG?" Zeng Liuqing smiled and shook his head, feeling that he was thinking wildly again.

Although Xiameng Electronics has developed electronic paper technology, this technology is a different way, more like a technology that it came out of on a whim.

As for the lithium battery technology, there are not hundreds of thousands or tens of thousands of institutions and companies currently researching in the world. The direction of technological breakthroughs has actually been written by people, and many breakthrough products have also appeared in experiments. In fact, these products are not yet in mass production.

There is a saying in the industry, "Once there is a major performance change in battery technology, the new elephant can rise immediately, and the old elephant is likely to collapse."

In order not to let themselves down, many companies in the lithium battery industry are willing to invest money in research and development. The same is true for Zeng Liuqing's company. Although the scale is not really large, ATL's investment in technology is still more than average. of domestic enterprises are higher.

Zeng Liuqing took this lithium battery to the factory laboratory.

The laboratory in the Baima factory area is a laboratory established by ASL with tens of millions of RMB. The laboratory includes electrochemical comprehensive testers produced in Germany, electrochemical workstations, battery charge and discharge test systems and other characterization instruments, as well as Michelona Supper and other related instruments. equipment.

"Huang Yan, let me test this lithium battery!" Zeng Liuqing said to Huang Yan, the chief engineer of Guancheng New Energy Technology Electronics, who was working in the laboratory.

As the company's chief engineer, Huang Yan is the person in the company who is most familiar with the structure of lithium batteries. He also has a great function in solving the problem of lithium battery swelling.

"Okay!" Huang Yan nodded and took the lithium battery, but did not let others test it, but walked to the electrochemical comprehensive tester. Zeng Liuqing often brings lithium batteries produced by other companies to test to compare the quality and difference of the products. As a technical nerd, Huang Yan personally likes the products of other companies.

Lithium battery performance test mainly includes voltage, internal resistance, capacity, internal pressure, self-discharge rate, cycle life, sealing performance, safety performance, storage performance, appearance, etc. Others include overcharge, overdischarge, solderability, corrosion resistance sex, etc.

Some projects will take a long time to test, and it may take several days for comparison, such as self-discharge test, life cycle test, etc. However, some items such as capacity, overcharge and other performance can be known in a short time. After each round of testing, Huang Yan is surprised by the lithium battery in his hand. After all the programs that can be tested have been tested, UU Reading www. .uukanshu.com Huang Yan was stunned.

Huang Yan immediately took the performance test report and went straight to Zeng Liuqing's office, knocked on the door of the office, and pushed the door in without waiting for a response from the people inside.

"President Zeng!" Huang Yan breathed out.

"Huang Yan, what are you doing?" Zeng Liuqing asked in confusion.

"Mr. Zeng, look at the report." Huang Yan directly handed the report to Huang Yan. Under normal circumstances, he would simply state the results of the test, because under normal circumstances, one or two outstanding performances are already very good, but this time There are too many performance items to report that stand out.

"It's only a few hours, how come there is a result so quickly? Isn't it usually two or three days to wait?" Zeng Liuqing took the report, glanced at it, and then his eyes straightened.

Because the first thing he saw was the capacity and charging speed. When he got it in his hand, he could simply feel the approximate capacity of the lithium battery. However, the result showed that the capacity was higher than he thought. More than half. And the most terrifying thing is the charging speed. Although it was only measured once, the charging speed this time is more than five times faster than normal.

What is this concept? A lithium battery that originally needed to be charged for 3 hours took only 40 minutes, which was faster than Zeng Liuqing's imagination.

"Huang Yan, you made your subordinates work hard tonight. I need to see a more detailed and prepared report at this time tomorrow." Zeng Liuqing said solemnly.

He now suspects that Huang Yan's test may have gone wrong. If there is no error, then he knows why Chen Yizhe gave him this lithium battery.

This is not a lithium battery, this is a big stick, and acquisitions are carrots.

Chen Yizhe's purpose is obvious, between a candy and a slap in the face, which one does Zeng Liuqing choose?
