In the huge vacuum laboratory, a lot of equipment is running. There are also several staff members there.
These workers wear specially made protective clothing, their whole bodies are tightly wrapped, and their helmets also have air tubes.
Super battery materials must be produced in a vacuum environment. Moreover, the process is extremely complex and the cost is very high.
"Boss, we have determined the production process of this material. The production cost has also been greatly reduced. We are currently working hard to find new production processes to further reduce costs. At the same time, our team is also developing the fast charging performance of this material.
…”
The person in charge of the research began to explain to Zhang Fan the progress during this period. The progress during this period was still very great.
After all, for many technologies, it is very difficult to start from scratch. But it is relatively easy to reduce costs and move to mass production.
During this incident, the laboratory produced many samples, and with enough samples, large-scale experiments can be carried out.
The production cost of the first one was hundreds of millions of yuan, but now the production cost of each one has been reduced to 30 million yuan.
But even so, the cost is still an unacceptable price. A coin-sized battery costs 30 million yuan, no matter how wealthy you are, you would not dare to do this.
Not to mention 30 million, even the cost price of 300,000 is not up to commercial standards. If it wants to be put into commercial use, it must be reduced to at least 30,000.
Therefore, the road is still very far and needs to be explored slowly. Moreover, this is a money-burning project. In such a short period of time, this project has burned more than 20 billion in funds.
There are still many things to study next. In addition to reducing costs, they also need to study how long the life of the super battery is, how safe it is, how to charge it at the fastest speed, etc.
"Continue to carry out research and development, money is not an issue now. I hope that our battery can be put into mass production as soon as possible. For people, this battery is a blessing for mankind."
Zhang Fan said seriously, and the person in charge nodded. This super battery has great uses. If it is put into use, the human energy system will undergo major changes.
Zhang Fan came directly to the Military Research Institute after leaving the Energy Research Institute. Super batteries are a big killer, especially for some specific equipment, they are more lethal.
Even if such a super battery can be mass-produced, Zhang Fan will not take it out easily. This thing can be kept secret for as long as it lasts. This is the weight in Zhang Fan's hand.
"Have the head of the submarine team come to my office."
Zhang Fan came to the Military Research Institute. The R&D center of Tieying Group is also located in the underground base of Lanhai City.
After these years of development, the underground base of Lanhai City Headquarters has continued to expand. It has not only expanded to the surrounding areas, but also expanded underground.
Some important research institutes are hundreds of meters deep underground. They are heavily guarded and require many security checks to enter and exit.
For the submarine project, after the establishment of Tieying Group, a special research and development team was established. Because there was no experience, the first project to start was the electric mini-submarine project.
For such a project, Longteng Group still has a little experience. After all, Longteng Group has experience in building sightseeing submarines.
But small tourist submarines and military submarines are completely different things. In front of military submarines, tourist submarines are just big toys.
Military submarines are the goal of this research group. Since the establishment of this group, they have been busy.
"Everyone, sit down, how is the current progress of the project?"
Zhang Fan asked with concern. Submarines are strategic-level weapons. Once they have such a thing, even the United States will have to put it on the line.
"Boss, the progress is relatively slow at the moment. We don't have any construction experience. Even conventional submarines are very difficult for us. Nowadays, advanced conventional submarines all have AIP systems, and we don't have any technical reserves in this regard."
The person in charge said seriously that submarines are not that easy to make. Especially in today's society, it does not mean that you make a ship that can run underwater and it is a submarine.
If you want to have combat capability or even deterrence capability, your submarine must have strong performance. What's the use of just making a thing that can only run underwater.
"Can we use pure electric power, just like a car, directly omitting the engine..."
Zhang Fan asked seriously.
"Chairman, this plan seems to be fine. But according to the current battery technology, the endurance of the pure electric submarine produced will be very weak."
The person in charge said seriously. If pure electric submarines were feasible, all countries would have developed them long ago.
The amount of electricity that batteries can store is limited. Even with all-solid-state batteries now available, pure electric submarines still have a very long cruising range.
The most critical supply is very difficult even if there are ocean-going supply ships. If it is fuel, it can be refilled quickly.
If it's charging, I don't know how long it will take to charge such a large submarine.
“What if we use graphene batteries?”
Zhang Fan's words stunned everyone.
"Currently, our company has made great breakthroughs in the research and development of graphene batteries. The new graphene battery is better than all-solid-state lithium batteries. The energy storage of a graphene battery of the same volume is three times that of all-solid-state batteries. Finally,
The important thing is that graphene batteries charge very quickly. The charging speed is hundreds of times faster than ordinary batteries..."
Zhang Fan threw a bomb. This bomb made everyone's eyes light up immediately.
If this is the case, pure electric submarines can be developed and tried. If graphene batteries are used, the performance of the submarine may be very good.
Especially on the supply issue, as long as the supply ship is used to recharge, even a large submarine will be recharged very quickly.
Looking at everyone's expressions, Zhang Fan laughed. This is just a graphene battery. If everyone knew about super batteries, they would probably be even more scared.
When it comes to energy storage, the energy storage of super batteries is hundreds of times that of graphene batteries. When the time comes to replace graphene batteries with super batteries, all the disadvantages of pure electric submarines will disappear.
The performance of conventionally powered submarines equipped with super batteries is comparable to that of nuclear powered submarines. As a pure electric submarine, it has great advantages.
At least it saves a lot of space. There is no need to install an engine, just an electric motor can directly drive the transmission shaft.
This advantage is even better than that of a nuclear submarine. A nuclear submarine must also have a reactor. The heat generated by the reactor drives the turbine and then drives the transmission shaft. This wastes a lot of space. For a submarine, every bit of space is very precious.
