The users can freely choose the control parameter values for machines. For example, the speed (in Rotations Per Minute -RPM-), the time (in minutes -min-), the temperature (°C) or the line speed (in meters/min), etc. To assemble the prepared electrodes, there is an electrode slitting machine, a winding machine, a welding machine, and a machine to finally degas, fill the cell with the liquid electrolyte and seal the cell (Figure -Figure ). The latter machines (Figure -Figure ) do not have any manufacturing parameters associated with them in the current version of the BMM application. If the user wishes to fabricate a half cell (with Lithium metal), they can pick the prefabricated Lithium metal electrodes available on the shelves, which they can directly use in the winding machine along with the working electrode. To perform the formation step and evaluate the performance of the manufactured cells, an electrochemical testing machine (potentiostat) for 18650 format cells is also present in the virtual environment (Figure ). The potentiostat can simultaneously accommodate up to nine cells (both half or full). This helps to compare the cells manufactured using different manufacturing parameters. Upon testing, the gravimetric energy density, a GCPL curve corresponding to the chemistry used, and feedback are displayed for each cell in the potentiostat (Figure ). The feedback shows other key properties of the cell, such as the mass loading of each of the electrodes, and also comments regarding all the mistakes made by the users during the fabrication procedure, if any. The feedback is provided at the end since it is helpful to perform evaluations of the user's performance if required.
