Chapter 130 (2/2)

It can be said that under the same volume, the electric energy stored in the battery in his hand can definitely reach dozens of times that of the graphene battery still in the concept. However, considering the heavy weight of the superconducting battery made of copper-based superconducting material, Therefore, the actual energy density should only reach about 15 to 20 times that of the legendary graphene battery.

At the same time, in terms of cost, the price of this battery is also very high, not to mention the price of copper-based superconducting materials. After all, copper-based superconducting materials are only controlled by Wang Bin himself, and mass production has not yet started, so the price is not easy to calculate.

However, according to Wang Bin's preliminary prediction, the price of copper-based superconducting materials should be at least 10000 yuan per kilogram, and the weight of the battery in his hand is about one kilogram.

That is, the price of superconducting materials in this superconducting battery alone has reached the level of tens of thousands of yuan. If the cost of other aspects at home, the cost of such a one kilogram superconducting battery is more than 20000.

However, this is only the cost. If it is to be sold, Wang Bin will not only sell at the price of 20000, but will definitely sell at a higher price.

But anyway, this kind of battery is definitely a rare super battery.

In other words, if the superconducting battery in his hand is installed on an electric vehicle, the range of the electric vehicle can definitely be more than 50 times.

Thinking of this, Wang Bin found that in fact, electric vehicle batteries are also a very good project. After all, the number of electric vehicles in China has reached as many as 300 or 400 million, and the annual output has reached tens of millions.

But then Wang Bin rejected his idea. After all, if such a battery is really only used in electric vehicles, it is definitely a waste.

Even if it is to be used, it should also be used in electric vehicles or other large vehicles, such as aircraft, ships and aerospace equipment.

Of course, since the battery has been developed, Wang Bin will not give up in such a large market as the electric vehicle battery market, so if the current situation of this battery is put into the electric vehicle battery market.

Not to mention that the price is too high. Only the performance of this battery, once put into the electric vehicle battery market, can definitely have a fatal impact on those electric vehicle battery manufacturers. Then countless electric vehicle battery manufacturers will go bankrupt and many people will be unemployed. This is definitely not what Wang Bin wants to see, nor what the country wants.

Therefore, if this battery wants to be put into the electric vehicle battery market, it must be modified before it can be put into use.

For example, it is OK to reduce the performance to less than ten times the energy density of ordinary lithium batteries, and at least ten times higher than lithium batteries in terms of price. In this way, it is only possible to focus on the high-end electric vehicle market.

In addition, in the electric vehicle market, Wang Bin will not give up. Although with the situation of Wang Bin and Tiangong technology, there is no way to produce electric vehicles. Wang Bin does not have the equipment or qualification.

However, there are still many electric vehicle manufacturers that can't operate in the country. If necessary, Wang Bin can buy an enterprise and produce it himself.

Thinking of this, Wang Bin shook his head and decided not to think about these things first. He decided to continue the experiment of superconducting battery technology first. After all, the superconducting battery in his hand that he had just made is only the first generation of superconducting battery technology according to the knowledge of the system.

As the first generation technology, it naturally has some defects. For example, in terms of volume and energy density, the largest of the first generation superconducting battery technology can only be to this extent, which can no longer be increased.

At the same time, different from other battery technologies, this first generation copper based room temperature superconducting battery technology can only be used as a whole piece by piece. It can not be used in parallel or series like other batteries to improve the capacity and output voltage of the battery.

However, when it came to the second generation copper based superconducting battery technology in his mind, these problems were basically solved. The second generation copper based superconducting battery technology.

Not only in terms of single block volume, it can be larger, which can reach the size of 100 cubic millimeters, that is, the size of 0.1 cubic meters. At the same time, the power storage is more than ten times the original, that is, 500 kwh, that is, 20000 ampere hours, can be stored in a square superconducting battery of 10% 10 cm.

You know, this is 20000 ampere hours, far exceeding the capacity of lithium batteries in all household electric vehicles on the market! After all, the lithium battery capacity of ordinary household electric vehicles is less than 100 amps. Even if it is a super large capacity, it is only about 110 or 20 amps, about 25 degrees to 50 degrees.

It can be imagined that the electric energy stored in the second generation copper based superconducting battery is so huge.

At the same time, there has been a qualitative improvement in the discharge voltage. In the original first generation, the maximum discharge voltage was about 100 volts, but now the maximum discharge voltage has reached 500 volts, that is, the discharge voltage is five times higher than that of the first generation copper based superconducting battery.
