Computational analysis of capacity fade in spinel-based cathode and artificial graphite anode |
| 초록 |
A comprehensive mathematical model is developed to study the cycling performance of LiMn2O4/graphite lithium ion cells. The proposed model takes into consideration the formation and dissolution of the solid electrolyte interphase (SEI) at the anode, Mn(II) dissolution of LiMn2O4 cathode active material due to Mn(III) disproportionation reaction and its effects on the SEI at the anode as well as the formation of cathode electrolyte interphase (CEI) on the cathode. The developed model is incorporated into the Newman’s Porous Composite Electrode framework (PCE) and implemented in the battery module of COMSOL Multiphysics. The proposed model is used to study the effects of variations in temperature and voltage range of cycling on the capacity fade and changes in volume fraction of cathode active material, resistance in the cell and SEI thickness. |
