Our BMM, described in this Concept, offers an innovative immersive environment in which users from the same or different geographical locations can get training in battery cell manufacturing. The current version is a significant leap forward with its features. It is now possible for multiple users from around the world to join the application simultaneously and interact with each other through avatars and voice. It also allows the instructor of the classes to guide users directly by being present in the application. The application consists of several independent rooms, which can be accessed by the users where a virtual battery pilot line is present. The pilot line includes all the equipment required to fabricate a complete 18650-format cell using the chemistry selected by the user(s). The application provides the users with the freedom to choose any value for manufacturing parameters and observe its effects on final electrode/cell properties such as mass loading or gravimetric cell energy density. Students can track the process and sequence they have chosen by using the virtual labels embedded in the virtual products of the process. The application also includes functions that speed up time, like a kind of "time machine". This makes it possible to fast-forward through time-consuming steps in the process.
