Hi all
I am a new comsol user.I am following the instructions of the Li-ion Battery model.Now in the input parameter they say that 17.5 A/m^2 corresponds to 1C charge/discharge rate.but they have never mentined the the capacity (AH/m^2) of the battery.How can they correspond 17.5A/m^2 to 1C without deciding or knowing the capacity of the battery
Similarly in the 2D_spiral tutorial model with the same inout parameters as 1D model they correspond 3.3e4 A/m^2 to 1C.
Just want to know how to decide 1C(C-rate) with the input parameters that they already have.I am sure there should be a formula to get the theorectical capacity(Ah/m^2) of the battery with the input parameters that they have.

Thanks

Jalaj
