The coin cells are assembled into a CR2032 form factor using the coin-cell assembly robot, co-developed with Chemspeed Technologies, which is part of the Aurora platform. Batches of 32 cells can be routinely assembled. We use a 15 mm diameter graphite electrode as anode (1.2 mAh/cm 2 , Customcells), and a 14 mm diameter nickel-rich lithium nickel manganese cobalt oxide (NMC622) electrode as cathode (1.0 mAh/cm 2 , Customcells). As electrolyte, we use 100 µl of a 1 M solution of lithium hexafluorophosphate (LiPF 6 ) in a mixture of ethylene carbonate (EC) and ethyl methyl carbonate (EMC) in a 3:7 ratio (Solvionic), respectively. The electrolyte is dispensed using a gravimetric dispensing unit (Chemspeed Technologies GDU-V) and also contains 2 wt% of vinyledene carbide (VC) to aid formation of a passivating solid-electrolyte interphase on the graphite electrode. Glass fiber separators (Whatman) are used to separate the electrodes; compatibility of the assembly robot with polyolefin separators (e.g. Cellgard) is being improved. Based on the cathode areal capacity and its electrode area, the corresponding target "recipe" capacity of each cell is 1.54 mAh.
