Lei Jun: Xiaomi battery packs have undergone over a thousand tests, many of which exceed the requirements of national standards testing.

Today, Xiaomi Group founder, chairman and CEO Lei Jun started a live broadcast on Little New Year's Eve. Lei Jun said during the live broadcast that our battery pack is made up of rows of battery cells. We have added a layer of double-sided water cooling behind every row of battery cells. In this way, when a certain battery cell fails, it can quickly dissipate the heat. This makes it safer. In addition to the double-sided cooling, the battery pack also has a water cooling plate to help the battery dissipate heat quickly. Furthermore, there is aerogel between the battery cells.
