On March 26, it was announced by the Xiaomi official today that the flagship Xiaomi 11 Ultra, released on March 29, will launch the super fast charging silicon oxygen negative battery technology, which can achieve greater energy density, higher capacity and faster charging.

Xiaomi officials said that they had tried the silicon carbon negative electrode battery technology on the concept machine MIX Alpha in 2019. This time, the silicon oxide negative electrode battery added silicon oxide compounds on the negative electrode of the battery, making silicon particles not easy to break and powdery. In theory, it has 10 times the lithium ion storage capacity of traditional graphite materials; The problem of low first charge efficiency and short battery cycle life of the previous generation of silicon carbon negative electrode batteries was also solved by adding lithium to nano silicon.

The use of silicon oxide negative battery on the Xiaomi 11 Ultra instead of the MIX model also shows that this technology has a mature mass production capacity. According to previous information, Xiaomi 11 Ultra is equipped with a 5000mAh battery, which supports 67W wired and 67W wireless fast charging.

In addition to preheating the new battery technology, Xiaomi today announced the new self-developed chip at the press conference on the 29th with the Slogan preview of "My heart is surging". However, from the words of the official poster "microchip" and the previous rumors, it is possible that Xiaomi's self-developed ISP chip used for mobile phone images may not be SoC.
