Is the release of Weilai solid-state battery really better than blade battery?

Perhaps many people don't know that Weilai Automobile ranks third in the market value ranking of global car companies, second only to Tesla and Toyota. The reason why Weilai Automobile has such a large market value is mainly because of its first car ET7, followed by core technologies such as "autonomous driving technology", "second generation power station" and "150kw solid-state battery pack", which makes the market generally optimistic about Weilai Automobile.

You should know the 150kwh solid-state battery scheme released by Weilai, which can make the new car have a maximum battery life of1000km. From the cruising range, we can see that the market is shocked by this car, so what is the solid-state battery? Let's take a look today.

At present, there are two kinds of batteries in the new energy market, one is lithium iron phosphate battery and the other is ternary lithium battery. In fact, these two kinds of batteries are similar in structure, mainly composed of positive electrode, negative electrode, diaphragm and electrolyte, so we call them liquid batteries.

Solid state batteries are just the opposite. There is no gas or liquid in its battery. All substances exist in solid form, which is different from electrolytes. This leads to great differences between solid-state batteries and liquid-state batteries in terms of safety, stability and easy energy storage.

What are the advantages of solid-state batteries? The biggest advantages of solid-state batteries are large mass, high energy density and high volume energy density. The cruising range of 1000 km is enough to stand out in the current battery market, which is related to the high energy density of solid-state batteries. Compared with the traditional liquid battery, it is also non-flammable, non-corrosive and non-volatile. And there is a great guarantee in terms of security. Like in the past, cars often spontaneously ignited and exploded, and solid-state batteries did not.

The development of solid-state batteries also has great disadvantages: 1 The disadvantage is the technical bottleneck, and the second disadvantage is the high cost. The manufacturing cost of solid-state batteries is very complicated, and a complete industrial chain has not yet been formed.

What is the development stage of solid-state batteries in China? At present, most battery suppliers in the market have R&D plans for solid-state batteries, such as Toyota, Volkswagen and Contemporary Ampere Technology Co., Ltd. However, solid-state batteries have not been mass-produced internationally, let alone put into new energy vehicles, and are still in the research and development stage.

In fact, compared with Tesla, Toyota and Volkswagen, Weilai, as a new force in building cars, is bound to rise strongly. He dares to declare that he can stick to 1000 km with great fanfare, which shows that he must have a certain foundation behind him. After this communication, I believe that domestic brands should continue to strive to develop battery technology.
