CC, the fastest update material empire!

Qin Hai pays attention to Zhang Wei's expression, but he just smiled and did not explain anything.

This kind of thing is the favorite of Qin Hai, and he believes that after reading the entire experiment, Zhang Yizhen will know how unscrupulous.

In the blink of an eye, the experiment has been carried out for 5 minutes, and Zhang Wei believes that the battery power will be exhausted.

However, the speed of the electric fan is not slow, and she still whizes.

Zhang Wei nodded and can have such power output capabilities, plus the power of ordinary nickel-cadmium batteries, is suitable for the use of electric cars, no wonder Qin Hai specializes in calling him. Visit.

6 minutes, the fan is still rotating at high speed ... 7 minutes ... 8 minutes ... Zhang Wei's eyes are straight, no, this small box stored in this huge power.

According to this calculation, the battery box volume of the electric vehicle will be reduced by half, and the weight will also decrease in the same scale, which means that electric cars can have more space for ride, this is the key competitiveness of electric vehicles.

One of the shortcomings of electric vehicles is that the weight of the battery is too large.

If it reduces the number of batteries, it will make the electric vehicle's battery life.

Battery cars in the later generations generally reach more than 300 kilometers or more, for this purpose, there is a need for a battery with more than 500 kg.

Although the engine of electric cars, gearboxes, etc. are light than fuel vehicles, but it is completely unable to unable to offset the weight of the battery.

The engineers are educated, which is to increase the specific energy of the battery, which is the amount of power stored per kilogram, thereby reducing the total weight of the battery in the car.

From this experiment, this battery is also surprised.

10 minutes ... 11 minutes ... 12 minutes and 17 seconds!

The red indicator on the battery case suddenly extinguished, the inverter issued "click"

One, cut off the power supply.

The electric fan is broken, the seaflets continue to turn, gradually slow, and finally stopped.

Zhang Wei did not wait for the fan of the fan to stop, and he took the palm of his face, and his face was smiling.

I said to Kaan: "Mr. Caan, this battery is great, this is the best battery I have ever seen!

With such a battery, our new energy car has true practicality.

"Zhang is always anxious, the experiment has not ended yet.

Qin Hai smiled and interrupted Zhang Yanyu.

"Already not over?"

Zhang Wei is strange, is this not perfect enough? A assistant disconnects the battery box with the inverter, and then pulls a power cord, one is inserted on the battery case, and the other is inserted on the power outlet on the wall.

Zhang Wei was able to see.

The other party is charging the battery, and it is estimated that it is ready to be full of experiments.

"When charging, please tell me this new battery.

Zhang Wei looked at Kaan and said.

With his experience, the battery charging time is very long, even with so-called "fast charge"

At least half an hour or more, this is still for this small battery.

If it is the 500 kg battery used in the car.

It is a miracle with six or seven hours.

This round of the wheel shirk, he said: "Still reading the experiment.

I am worried that I can't make it clear within two minutes.

"What, two minutes?"

Zhang Weiyi.

Didn't wait for him to react, Kaan's assistant has pulled the battery's power cord, the total charging time, even less than a minute.

The two assistants reconnected back to the inverter as previously, one according to the switch.

I saw that the fan flew again.

"This this ..."

Zhang Wei, only felt that the blood of the whole body was in front of the head, and he felt dazzling.

He was very difficult to control his excitement, pointed to the battery box asked Qin Hai: "Is this the super capacitor!

"exactly.

Qin Hai has already expected Zhang Yizhen's performance, you can say this.

No one knows the value of the super capacitor than Zhang Wei, so no one will be more ecstatic than Zhang Wei.

One of the shortcomings of electric vehicles just said is that the battery weight is too large, and its biggest shortcomings are the so-called "no one"

The maximum, but the battery charging time of electric cars is too long, so that it cannot supplement energy as fuel cars.

The fuel car can be opened 500 to 700 kilometers at a time, and then you can find a gas station, and you can fill the fuel tank for a few minutes.

After the electric car is full of electricity, it can only be opened 300 kilometers, followed by spending five or six hours to fully charge.

In this way, electric cars can only be used for short run, 300 kilometers a day, then spend a night to charge.

This limitation is fatal for electric cars, which greatly limits the market of electric vehicles.

For ordinary families, who will buy a car that can't run long-distance? There are two kinds of electric vehicles, one is a rechargeable battery, and the other is a supercapacitor that is much longer than the ordinary capacitor.

The advantage of the capacitance is that the speed of charging and discharging is very fast, theoretically even reaches the extent of instantaneous and instantaneous release. Currently, the premise is that the external circuit will not be burnt.

Fast charging features can solve the problem of charging speed, and the rapid discharge characteristics satisfy the power output requirements.

When Zhang Wei, Zhang Wei, she only understood why Kanan dared to believe in confidence to expand the power output by 10 times. If the load capacity of the inverter and the wire fever, the supercapacitor output power is increased by 100 times is also easy. Best.

A few years ago, Qin Hai once said to Zhang Wei's thinking of the supercapacitor, Zhang Weijian only holding a semi-confidential attitude, and quickly placed the brain.

The reason is nothing, that is, the rechargeable battery has sufficient technical reserves, but the super capacitor is still in the stage of laboratory verification.

Vendors engage in new energy vehicles are committed to improving existing charging batteries, even if some manufacturers have proposed the concept of supercapacitor vehicles, it is only limited to a vision expectation.

Who can think that Qin Hai actually solves the problem of supercapacitance, and the capacitance is more energy, power output capability, and charging speed have reached approximately perfect level. How can I not let Zhang Daoli crazy.

"Mr. Kan is an expert in the Brazilian Aviation Technology, has an outstanding tree in supercodent and supercapacitors.

This time, our Materials College specially hired Mr. Ka'an as a chief expert in Super Capacitor Lab, in front of this battery box, is the latest graphene supercapacitor for Mr. Kan.

Qin Hai to Zhang Wei.

The concept of supercapacitor has been previously designed, but research progress is very slow, one of the key factors is the constraints of electrode materials.

The principle of capacitance, simply, is separated by a different medium, and a positive charge and negative charge are stored on both electrodes, which reaches the effect of the electric storage.

To expand the capacity of the capacitor, one is to increase the unit area storage capacity of the electrode, and the other is to deposit a larger electrode in a limited space. To this end, it is necessary to find a better electrode material.

The discovery of graphene has opened a door to the supercapacitor research.

Grainne is a single layer of atomic structure, which is the world's thinnest material, so in the determining volume of capacitors, the maximum area of ​​graphene electrodes can be accommodated.

At the same time, the planar layer of graphene is facilitating the infiltration and ion adsorption and desorption of the electrolyte, thereby improving the energy storage density of the capacitor.

In the case of Sao Paulo, Kaan listened to Qin Hai, I knew that this is the most ideal capacitor electrode material, so it will not hesitate to go to the Qinhai.

In these cases, Qinhai does not have to explain to Zhang Wei, and the operation is specialized, and Zhang Yizhen does not necessarily understand.

However, the supercapacitor is in front of Zhang Wei, this technology has a significant impact on the development of new energy vehicles, and Zhang Yizhen is a clear.

"This capacitor can now achieve mass production?"

Zhang Wei took the battery box with super capacitance, and went to look at it, and asked Qin Hai and Kaan.

Cartoon said some regrettime: "I think this capacitor has not reached the ideal level I hope, so I don't agree with the investment.

However, Qin always believes that it has now been mass production.

Qin Hai smiled: "Mr. Kan, I did not stop you from optimizing the super capacitance, we all expected you to take better super capacitance.

However, Zhang is always waiting, if we don't carry out the mass production of supercaps now, we can't see the sample cars of new energy vehicles next July.

"Two things do not conflict.

Zhang Wei said, "We can first launch a supercapacitor generation, after the Mr. Kaan took out better technology, we will then launch the second generation and three generations.

If the car has never been in place, foreign experience is to launch a new improvement model every three months, and the capacitor can be used as a major replacement. It is not too much in one year.

"We are conducting a comprehensive test of super capacitors, and Zhang always has to cooperate with us to conduct some tests.

Our Super Capacitor Production Line of our Daqin Group has been implemented in two months, and it can achieve mass production later in two months.

The first batch of production capacity is 4 million months.

Qin Hai to Zhang Wei.

"A car should use 4000 capacitors, 4 million can meet the needs of 1,000 cars, so our annual production is 12,000 units ... Currently, it is enough.

Zhang Wei said.

"Annual production of 12,000? Too few.

Qin Hai did not satisfy, "You can rest assured, I will start the construction of the second production line immediately, and the capacity can be extended more than 10 times in half a year.
