In Simubat 4.0, the user has to follow a pre-defined and fixed manufacturing recipe to achieve a target energy for the cell being prepared. Simubat 4.0 guides the user by specifying parameter values to choose for each process step. At each step, users had to select correct parameter values among three options (e.g. among three pre-defined slurry drying temperatures) to be allowed to proceed further in the manufacturing, ensuring accuracy as the values were derived from real-world experimental data. Furthermore, Simubat 4.0 supports only one single user, and it allows the production of only one cell (NMC vs. graphite) every time it is used. Additionally, this tool is coupled with an MR post-processing tool, which combines real-world and digital content to provide another user wearing a HoloLens headset with an interactive visualisation of the electrode microstructure produced by the first user in the VR environment. This triggers collaboration between the user evolving in the VR environment and the one wearing the MR headset, the latter providing oral feedback to the first one about the properties of the electrodes in order to allow further optimisation of the process .
