Hello Everyone,
I am obtaining the EIS from the DFN model and the EIS profile is shifting to the right side when we increase the charge C rate from 0.3 to 1C or 3C (refer to the figure below).
How can we explain this behavior in the DFN model? Please feel free to comment on it.
Thank you in advance.
Akila Eranda Jayasinghe, The DFN model's EIS behavior aligns with expectations for higher charge rates, indicating increased charge transfer resistance and reduced diffusion time constants. Factors like electrode microstructure, complex pore structures, and solid-electrolyte interphase (SEI) thickness can also contribute to this shift. Mitigation options include increased SEI stability, better electrode design, and new electrolytes with rapid ion transport capabilities.
Alvena Shahid Thank you for your comment. Would you be able to provide me some references for further reading about this.
