Eli5 How can the new Xiaomi phone charge from 0 to 100% in 9 minutes ? What about the heat the battery must produce from charging this fast ?

Could be they have devised a battery with lower internal resistance(less heat generated), increased the surface area to allow for better cooling(sperating the battery for example) or that they care less about battery longevity and want to cook the think just to show off the best specs.
