The bootstrapping procedure was employed to assess experimental variability and to estimate the whole population of values. The mean specific discharge capacity during the third cycle on the masked substrate, as determined from the bootstrapping, is 204.5 mAh/g with 95% percentiles of (201.6, 207.1) mAh/g, corresponding to a maximum 1.4% margin of error. The relative standard deviation from the bootstrapping analysis is 0.7%, which is significantly superior to the results previously obtained in our laboratory for the cycling of coin cells assembled using the robotic system 51 . However, the capacity values for the robot-assembled coin cells were not normalized by mass and had a bootstrapped bimodal distribution, while for our system a gaussian-shape distribution is observed (Figure ). To estimate the minimal number of required experiments to understand the interexperimental variability, the sampling procedure followed by bootstrapping could be applied, and the uncertainty threshold should be specified based on the goals and reproducibility criteria of the research. We suggest that 8 or 9 SDC experiments are an easily accessible lower threshold for the minimum number of repeats (Figures ), comparable to those reported by Dechent et al. .
