In this section we describe SIMUBAT 4.0, a serious game we have developed to interact with a LIB or sodium-ion battery manufacturing pilot line represented in a VR environment. Such representation is a digital twin of our in house battery manufacturing pilot line, located at the Laboratoire de Réactivité et Chimie des Solides (Université de Picardie Jules Verne and CNRS), in Amiens, France (Figure ). . All along the game, the player is guided with position markers indicating which manufacturing process step he/she has to undertake, similarly to a GPS-empowered system like Google Map. At the beginning of the game, the player has to go to a board that lists the envisioned LIB cell electrodes chemistries and formulations, electrodes properties (e.g. porosity) and cell energy (Figure ). The game contains a database of several of those targets which are proposed randomly at the beginning of each game. Such database is fully configurable and targets can be suppressed or added.
