Chapter 136 Chapter 136

"Boss, whether Bufan Technology's battery can keep up...!"

This mysterious question is not only considered by Jili Group, but also by many domestically-made cars.

Of course, this thing is not a problem for Qi Rui, Lima and other car companies that have already tasted the sweetness.

"Go, sign a contract of 5 million yuan! We just want to hold on to Bufan Auto's thighs. He eats meat and we drink soup!" Boss Qi Rui was delighted. The sales volume has rebounded significantly in recent months, all because of his decisiveness. decision.

They have purchased metals and gearboxes of extraordinary technology, and now solid-state batteries are about to come out. This should be an excellent opportunity for them to seize the market for new energy vehicles. The long battery life is enough to meet this demand.

"Hello, we are Lima Automobile Company, and we would like to pre-order 3 million solid-state batteries with your company."

……

Although the solid-state battery released by Bufan Technology has attracted widespread attention, but this time everyone has learned to be smart, and it is right to look at the results, and the flag is finally beaten in the face.

Many car companies independently research batteries, such as Tesla and BYD, which are all on the road of autonomy, so they don't quite believe the solid-state batteries claimed by Bufan Technology.

On the contrary, Qirui, Lima and other small car companies without independent research and development capabilities actually have an inexplicable trust in Bufan Technology.

Of course, big car companies such as Jili are always hesitant, after all, their own face is very important.

When it comes to power batteries for new energy vehicles, battery companies are naturally the most authoritative.

Famous suppliers in the world include LG, Panasonic, etc. Of course, the domestic Shunde era is also one of the best giant companies in the industry.

In their eyes, what Bufan Technology claims is extremely difficult, and commercial mass production is unrealistic, especially as LG is the leader, it is ironic that Bufan Technology is grandstanding.

However, it is true that it is difficult to mass-produce solid-state batteries based on current scientific research alone.

New energy vehicle batteries can be broadly divided into three categories: chemical batteries, physical batteries and biological batteries. Among them, chemical batteries and physical batteries have been used in mass-produced electric vehicles, while biological batteries are regarded as future electric vehicle batteries. One of the important directions of development.

Among the chemical batteries, lithium batteries are currently the most commonly used battery type. Although it has not been born for a long time, it has quickly occupied most of the electric vehicle battery market due to its high energy density and long cycle life.

Among them, the lithium batteries equipped with electric vehicles mainly include lithium iron phosphate batteries and ternary lithium batteries.

Compared with the early lithium manganese oxide batteries, lithium iron phosphate batteries do not have much difference in energy density, but their thermal stability is currently the best, and because of this, most car companies consider In order to meet the safety issues in actual vehicle operation, lithium iron phosphate batteries have become the main category of electric vehicle batteries.

Among them, the blade battery newly developed by BYD adopts a flat design to make the battery more suitable for vehicle research and development, elongating the battery into a blade structure, and changing the battery pack structure as before.

The blade battery realizes a completely non-modular internal structure, and the battery is elongated into a blade structure through an in-line arrangement structure, which greatly improves the volume utilization rate and improves the performance of the traditional battery pack by more than 50%.

This has greatly improved the endurance of lithium iron phosphate batteries to a certain extent, so that they can compete with Tesla's ternary lithium batteries.

Compared with lithium iron phosphate batteries, ternary lithium batteries used in Tesla Model S have much higher weight and energy density, which means that ternary lithium batteries of the same weight are more expensive than lithium iron phosphate batteries. The battery has a longer range.

However, its shortcomings are also obvious, and its security and stability are worse.Therefore, extremely high requirements are put forward for the battery management system, and a safety device needs to be installed separately for each battery.

In addition, due to the small size of the cells, the number of battery cells required for a bicycle is very large, which is why the Model S disassembled by Zhou Fan has so many AA batteries.

However, both batteries are essentially liquid batteries because they both use liquid electrolytes.

The solid-state battery released by Bufan Technology is the same in principle as these, but the electrolyte is replaced with a solid state, thereby improving the energy density, safety and cycle life of the battery.

Solid-state batteries have always been limited, and the unrealizable technical difficulty lies in how to replace the electrolyte without affecting the movement of electrons.It's like draining the water in the swimming pool and covering it with a thin film, so that although the weight of the entire swimming pool will drop, how can lithium ions move without water in the swimming pool?
There are currently three main research directions in solid electrolytes, namely polymers, inorganic oxides and sulfides.

However, Bufan Technology did not follow this route, but took a different approach and adopted the idea of ​​some superconductors to realize a brand new solid electrolyte.

Due to the idea of ​​some superconductors, electrons can be exchanged completely unimpeded, so that the process of charging and discharging can be carried out.

As for the foundation of this idea, Zhou Fan has already laid the groundwork. After all, Bufan Technology is a company that has published research on superconducting materials in Nature. It is not an exaggeration to apply some of the superconducting research ideas to batteries.

Of course, the ultimate goal must be superconducting batteries, and the battery capacity at that time may be even more impressive.

This is also a technological leap brought about by the system, otherwise the research on superconductors would not have made such progress.

Finally, the long-awaited solid-state batteries have been released, and several car companies that had already prepared them immediately divided up the first batch of production. Many car companies and research institutions have also purchased small quantities of solid-state batteries for research.

Zhou Fan is naturally not worried about other people's research, because he is the only one in the world in the research of superconductors, and he can upgrade his own solid-state batteries at any time.

On the contrary, the battery has been fixed, but Bufan Auto's own new energy vehicle has not been released, which can't help but make people imagine.

……

"This... This is really a solid-state battery!!! Smecta!" A research laboratory of LG Chem.

"What kind of material is this, Smecta?!"

"It feels a bit like a superconductor!!"

"How did he do that!!"

The solid-state battery released by Bufan Technology once again shocked the world's car companies!This time, it is not only the inner surprise of traditional auto companies, but even Tesla, which has always been the world's number one new energy vehicle, has to turn its attention to this magical and extraordinary technology.

"I'm afraid this has surpassed our design." Max frowned, feeling a sense of crisis for the first time.
