| Summary: | The demand for lithium ion batteries has increased due to the increasing need by consumers for
rechargeable batteries. In the effort to produce high performance batteries, mathematical model
becomes a vital instrument in helping batteries developers to understand the behaviour of the battery
systems during charge and discharge process. This understanding is useful in the optimization of the
battery design and parameters. This paper presents a mathematical model used to simulate the
intercalation process of lithium ions in the electrode of a lithium-ion battery. This model is used to
study the intercalation process through the lithium-ion concentration profiles during charge/discharge
of a rechargeable lithium-ion battery. This approach resulted in solving the diffusion equation in the
solution phase and the solid phase of the battery. Results from both phases are plotted and
compared. (Abstract by authors) |
