A new type of silicon-based battery product was launched. Officials say the battery can charge an electric car in about 10 minutes, which is faster than refueling?

According to reports, this new battery is designed with a 3D battery architecture, EV-grade cathode and anode made of silicon, which can further reduce the charging time of the battery. At the same time, the battery has also improved its energy density. After more than 1,000 cycles of charging, it still maintains about 93% of its capacity. According to the official announcement, it has been proved that the battery can be charged from 0 to 80% in 5.2 minutes and to more than 98% in 10 minutes.

Silicon-based materials have excellent energy storage potential and are considered to replace current graphite as a new anode material. Theoretically, the lithium storage capacity of the silicon anode battery can reach more than twice that of the current lithium battery using graphite anode, which is equivalent to nearly double the energy density of the battery. Once silicon-based materials can be formally used in lithium batteries, it will greatly help improve battery capacity and charging speed.

Enovix tested its fast-charging capability on a 0.27Ah lithium-silicon battery and claimed to have overcome four major technical challenges, including first-time charge battery swelling, first-time charge efficiency, and repeated charge swelling resulting in short service life. It is still unclear whether this battery is suitable for commercial and industrial mass production. Once it can be applied to automobiles on a large scale, electric vehicles will really have no anxiety about battery life, and the charging will be very fast for long battery life.

Nowadays, the short battery life and slow charging of electric vehicles have become one of the factors restricting the development. With the increasing number of electric vehicles on the market, the charging station seems to be even more insufficient. Especially during the peak holiday season, you may even have to queue for hours to recharge. The battery life of mainstream pure electric vehicles is within 500~600km, the actual mileage is even shorter, and the anxiety of battery life is also more serious.

The world's major car companies and battery manufacturers are actively developing new types of batteries to further improve the battery life of cars. The 4680 battery brought by Tesla helps to improve the car's battery life by more than 16%, while also reducing costs. Guoxuan Hi-Tech's new ternary semi-solid battery directly pushes the car's battery life to more than 1000km. The Ningde era will also bring Kirin batteries, and the performance is also noteworthy.

Next, more long-range models will be launched one after another, which will alleviate the anxiety of car battery life to a certain extent. However, if you want to improve the experience of electric vehicles, it is also particularly important to increase the charging speed. It is expected that domestic battery manufacturers will also bring more advanced fast charging technology.
