Recently publications have suggested best practices with regards to techniques and reporting for battery research. One area gaining attention is the need for battery cell replicates. In this perspective, the need for replicates is put into the context of the uncertainty in gravimetric capacity resulting from a component typically assumed as a constant—the current collector mass. The expected variation in reported gravimetric capacity just due to this factor for representative current collectors and battery materials will be discussed, and the additional importance of electrode loading to minimize the impact of this factor will be described.
