This is pretty smart thinking and could lead to some great developments. The problem with traditional superchargers is they reduce power before giving more power. Turbochargers use wasted power before giving power and thus can have greater peak power but don't have the low-end power that superchargers do because of the lag time between acceleration and exhaust gasses powering the turbo.
Subaru had a hybrid concept vehicle a few years ago where they put an electric motor on an engine to assist a turbocharger and give the engine a more consistent boost. It was a power hybrid concept not an efficiency powered concept (efficiencies were only relating to smaller engine size - not the battery assist). This electric-motor-on-the-charger idea makes more sense because you can just put a smaller motor on the turbo instead of on the engine, the motor could assist the turbo at low engine RPM and then at high engine RPM the exhaust gasses can take over and the electric motor could shut off.
Thus you have an electrically assisted turbo. This would be more efficient than a fully electric turbo because it would be powered by exhaust gasses much of the time. เอาไว้แค่ ออกตัวพอ
