제목 Computational Analysis of the Effect of Different Electrode Design Parameters on the Electrochemical Performance of Lithium Ion Cells
초록 To meet the various application requirements of LIBs, the energy and power density of LIBs needs to be optimized for a given electrode material by controlling its porosity and thickness. Changes in electrode thickness and porosity affect the electrochemical performance of LIBs. Hence we employ a mathematical model to study and optimize the electrochemical performance of graphite/LiNi0.6Co0.2Mn0.2O2 cells with different cathode thicknesses and porosities. A non-linear least square method is used to provide a better understanding of the different porosities and thicknesses on Li-ion transport in both liquid and solid phases. Ragone plots are generated for the various cell designs where the specific energy and average specific power are evaluated. The cells are optimized  for discharge times ranging from 10 h to 2 min in order to map the maximum performance of this chemistry under wide operating range.
