The relatively small variations in QCAM by 15% between all ΦCAM of comparable thickness, and by 7% when doubling the cathode thickness at constant composition, rationalized by the δ-parameter analysis, are promising outlooks for the Li2FeS2 battery chemistry. While these are significant changes to the cathode utilization, the loss in utilization is marginal compared to the areal loading increase 1.8 mAh•cm -2 to 3.7 mAh•cm -2 with increasing ΦCAM, and to 7.3 mAh•cm -2 upon increasing the cathode thickness. This increase of the areal loading by a factor of approximately five compensates the at maximum 22% loss in cathode utilization, so that the achieved areal capacities increase from 1.2 mAh•cm -2 to 4.4 mAh•cm -2 going from the lowest to the highest areal loadings (Figure ). Clearly, the higher δ -for instance in thicker electrodes -the more deviations of the attained capacity to the theoretical capacity can be expected.
