where N is the total number of diffusing ions, d the dimensionality of diffusion, t the total simulation time, M the total number of jumps observed and aA->B the jump distance of a generalized jump-event. From DJ the conductivity can be estimated by inserting DJ into equation 3 instead of Dtr. Our jump-diffusivity analysis predicts an activation energy of 0.27±0.01 eV and a conductivity of 4.1 mS cm -1 at 300 K.
