How the effective permittivity and the Relative permittivity of Materials are related to each other (Special case: for electrodes in Li-ion Battery)?

Actually, Is there any corresponding intrinsic characteristic of each grain/grain boundary (interface) in dielectrics with fixed value (e.g. εeff ~100 for CaCu3Ti4O12) or not ( εeff value is...
