is connected via a cable to a computer simulating the virtual environment, while the actionable 3D printed objects are connected to the computer via Bluetooth. Overall, this serious game allows involving four simultaneous players: the EV driver evolving in the VR environment and the three persons acting on the 3D-printed power generators. We have shown that these VR/MR serious games ease the understanding of the complex concepts behind the microstructure of the materials and their operation principles in rechargeable batteries. They also significantly raise the engagement and motivation of the students. [ Because of this, we have used them in numerous science festivals as they constitute very efficient tools to popularize complex battery science.
