vivo will release the new S19 series on the 30th of this month, and the appearance and battery capacity of the machine have been officially revealed.

The S10 will be equipped with a large 6000mAh battery, and the thickness of the fuselage is only 7.19mm, which is a significant improvement for the current mobile phone market.

Why is it possible to cram a 6000mAh battery into a 7.19mm body? According to the information given by the supply chain, this is because the machine will use a new generation of silicon carbon anode battery, which has an energy density about 20% higher than the traditional graphite anode battery and about 16% higher than the extreme graphite anode battery, and this new technology will be supplied by CATL New Energy.

The energy density of traditional graphite anode batteries is about 372mAh/g, while the theoretical energy density of pure silicon anode materials can reach 4200mAh/g, which is 10 times that of graphite anode.

However, the silicon anode expands during charging and discharging, and the reaction volume expansion rate of silicon and lithium is as high as 300%. Carbon wrapping is one of the effective ways to solve the expansion of silicon anode, so there is the birth of silicon carbon anode battery.

It is worth noting that the version with a large 6000mAh battery is equipped with the S19 standard version, and the battery of the Pro version is reduced to 5500mAh, and the fast charging of both machines is 80W power.
