Since the application is highly customisable, it is necessary to prepare a well-structured educational or training program to maximise knowledge transfer and retention. It should be prepared, considering the user's prior experience (students/trainees) in battery manufacturing as well as with VR. The lectures with VR sessions are usually where students learn with fun and still be at the centre of knowledge . One advantage of this application is that it allows the students to try and test things based on their knowledge and lets them be more autonomous, then reflect and understand the outcomes of their choices based on the results. Then, they can ask questions if they do not know or understand. A preliminary session was organised with the students of the MESC+ program, the previous version of the i-MESC Erasmus Mundus Master's Program . To avoid confusion between MESC+ and i-MESC, the latter name will be used to refer to both program versions hereafter. In this session, a total of 19 students from three different universities joined the BMM, from their respective universities located in Amiens in France (University of Picardie Jules Verne, 6 students); in Bilbao in Spain (University of the Basque Country, 6 students) and in Ljubljana in Slovenia (University of Ljubljana, 6 students) (Figure ).
