Data on the effect of particle size, porosity and discharging rate on the performance of lithium-ion battery with NMC 622 cathode through numerical analysis

Abstract

The data presented in this article are related to the computed results reported in the article entitled “A modeling approach to study the performance of Ni-rich layered oxide cathode for lithium-ion battery” [1]. The lithium-ion battery (LIB) employed in the simulation is made up of a LiNi0.6Mn0.2Co0.2O2 (NMC 622) cathode and lithium metal foil anode. The numerical simulations were carried out using COMSOL Multiphysics 5.4 software which is based on the finite element (FE) method. The data presented in this manuscript shows how varying particle size and porosity affect the performance of the battery as the discharging rate is varied. Four different particle sizes and six different porosities were varied for the purpose of understanding the above behavior. The data presented can be used to further the analysis reported in the accompanying manuscript and aid in design of other cathode materials for LIB and other battery systems. It can also be used to compare some measured results for validation purposes. A comprehensive analysis of the data is found in [1].
