As Tony took the glass and left, Wang Bin did not continue to stay in his shop, but directly returned to the real world.


    Back in the real world, Wang Bin did not go to the laboratory immediately, but first called Jia Jie and entrusted them with the task of designing and manufacturing the normal temperature copper based superconducting material production line. Of course, Wang Bin did not tell them the specific data of normal temperature Tongji superconducting material, but just told them some general data.


    For example, the production capacity of the production line, the products produced by the production line, and so on.


    Then he turned and left his office and walked towards his own laboratory.


    After all, since he has purchased the technology from the system, he must find a way to realize the technology. Of course, if he wants to realize the electromagnetic railgun technology, Wang Bin must first solve the problem of high-capacity superconducting capacitor technology.


    However, Wang Bin found that in fact, for basic materials, technologies like this are easier to implement, take superconducting batteries for example.


    Because now he has a copper based room temperature superconducting material, it is not difficult to realize a relatively simple superconducting battery.


    So it only took Wang Bin less than a week to get a copper based superconducting battery, or superconducting capacitor. Of course, the copper based superconducting battery is actually the simplest superconducting battery that Wang Bin obtained from the system.


    Wang Bin looked at the superconducting battery with a height of less than 10 cm, a thickness of only 2 cm and a width of only 5 cm.


    Although this battery is only the simplest of many superconducting batteries given by the system.


    However, in such a small battery, it stores 1000 ampere hours, that is, about 50 degrees.


    According to the data of the system, the electric energy stored by such a small superconducting battery can provide more than 50 consecutive maximum energy launches for electromagnetic rail guns below 5mm.


    What if you put this battery on other modern electric equipment! Not to mention anything else, take the electric car that everyone is using on the road.


    Generally speaking, the vast majority of electric vehicles on the market use 48v20a lead-acid batteries, and the storage capacity of a group of 48v20a lead-acid batteries is about once.


    In terms of output voltage, generally speaking, the maximum output of each lead-acid battery is only 12 pairs. If you want to achieve a higher voltage, the lead-acid battery must be connected in series.


    The voltage of a single lithium battery is smaller, often only a few volts. The lithium battery on the lithium battery electric vehicle is connected in series by a very large number of lithium batteries to meet the voltage requirements of the electric vehicle.


    The superconducting battery in Wang Bin''s hand is different. According to the data, the maximum output voltage of this battery is very large compared with lead-acid battery and lithium battery. It can reach the level of 100 volts at most. At the same time, in terms of instantaneous release of current, it is not comparable to lead-acid battery or lithium battery.


    After all, this copper based superconducting battery is essentially a super large capacity capacitor, so if necessary, this battery can release all the electric energy in the battery in one second.


    In fact, this is also the reason why this battery can be used as energy on the rail gun, because the current released by the rail gun is very large at the moment when it launches a projectile.


    Ordinary batteries and lithium batteries can''t reach it at all. If you use lithium batteries, you don''t have to wait for the rail gun to launch, and the batteries have burned themselves. After all, the nature of lithium batteries is no different from gunpowder.


    In addition, in terms of safety, since the main raw material of copper-based superconducting battery is copper-based room temperature superconducting material, and the main raw material of copper-based room temperature superconducting material is metallic copper, there are not too many chemical materials in it, so there is no fire or explosion in this superconducting battery.


    Of course, if there is a short circuit in the process of use, it is still possible to burn the superconducting coil in the superconducting battery, but the probability is not large. It is more likely to burn the short circuit place and even the wires.


    Therefore, that is to say, the storage capacity of such a small superconducting battery is 50 times that of the ordinary 48v20a lead-acid battery. The most important thing is the gap in volume. This battery is less than 1% of that of the ordinary 48v20a battery.


    You know, even if graphene batteries are favored by major companies and countries around the world, their energy density is about ten times that of lithium batteries.


    In general, the energy density of lithium battery is only three to four times that of lead-acid battery. In other words, the ideal storage capacity of graphene battery is about thirty or forty times that of lead-acid battery.


    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.
