<h2>Abstract</h2>
The replacement of conventional lithium-ion batteries with solid-state batteries is currently under investigation by many players both from academia and industry. Sulfide-based electrolytes are among the materials that are regarded as most promising, especially for application in the transport sector. The performance of anode, cathode, and solid electrolyte materials of this type of solid electrolyte is typically evaluated using manually assembled cells such as Swagelok cells, EL-CELLs, and in-house built pressure devices. Coin cells, however, are often disregarded. Though coin cells cannot accurately predict how a material will perform in an end-use application battery cell format, they are easy to assemble and can provide reproducible data compared to the other cell types, which make them an interesting option for testing the materials under conditions more relevant for their envisioned application. The coin cell preparation method presented in this work has been evaluated interlaboratory for reproducibility and, in addition, can be modified depending on the optimization parameters of the solid electrolyte, cathode material, bilayer comprised on cathode and solid electrolyte, lithium metal anode, and cell in general. Besides, an interlab round-robin test (RRT) is carried out between four laboratories, measuring defined electrochemical tests of sulfide solid-state batteries in coin cell configuration. This RRT for the preparation of coin cell solid-state batteries with sulfide solid electrolyte, lithium nickel manganese cobalt oxides cathode, and lithium metal anode is intended for academic researchers and provides guidelines of research in this field.
