Why does the ionic conductivity of grain boundary is normally larger than that of grain in solid state electrolyte?

when we use EIS to analyze the ionic conductivity of solid state electrolyte, we often find the calculated ionic conductivity of grain boundary is larger than that of grain, what's the reason?...

How can we identify the kind of transport ions (positive or negative ions) in a ionic conductor (for example solid state electrolyte)?

We fabricated a solid state electrolyte for Li ion battery, and some negative ions are weakly bonded with neighboring positive ions, we guess the negative ions also contribute to the total ion...
