| Summary: | This paper presents the lithium-ion concentration profile
simulation in the cathode for the half cell to predict the
performance of the lithium-ion cell. The mathematical
model is utilized in order to identify the lithium-ion cell
system in the solution phase. Then the model is used to
describe the discharge behavior of the rechargeable cell
based on the simulated concentration profile. For this
work, the cathode is the positive electrode employing
LiMn2O4 as the active material. In addition, the
numerical technique namely Finite Difference Method is
used to solve the material balance equation of lithiumion
cell. This method is compared to other methods to
identify the concentration profile. Nevertheless, the
solutions in this paper merely focus on the concentration
profile of lithium-ion in the cathode under galvanostatic
discharge in the half cell. |
