- Abstract
- Lithium-ion batteries (LIBs) have become integral to various aspects of the modern world and serve as the leading technology for the electrifi cation of mobile devices, transportation systems, and grid energy storage. This success can be attributed to ongoing improvements in LIB performance resulting from collaborative eff orts between academia and industry over the past several decades. However, existing methods for calculating the energy density at the electrode level remain ambiguous and complex, complicating the comparison of energy density metrics across scientifi c reports. From this perspective, we highlight several testing parameters that are frequently overlooked in the academic literature but are critical for the practical applicability of LIBs. We discuss the metrics that infl uence the energy density, including the (i) loading level, (ii) electrode density, and (iii) N/P ratio, as well as the relationship between each parameter. Additionally, we consider the eff ect of the gravimetric capacity increase on the energy density. We hope that this report will serve as a guide for key battery design parameters at the electrode level and for deriving optimal electrode conditions in future LIB research.
