Hi experts,

I am using 2RC Equivalent circuit battery model (time domain) to fit  26650 LiFeP cell data at 25,50,0 °C. When I compare between these 3 temperatures, 50 °C has highest capacitance value, then 25 °C and 0 °C has the lowest capacitance value ? What is the practical reason ? Please provide some ref or papers. One RC represents charge transfer and other RC means diffusion.

Thanks
