The dynamic response of polymer electrolytes

A method of characterising transport mechanisms in solid ionic conductors has been proposed which involves a comparison of a structural relaxation time, t, and a conductivity relaxation time, t . This differentiates between the amorphous glass electrolyte and the amorphous polymer electrolyte, the latter being a very poor conductor below the 7. A decoupling index has been defined where 

The simplest model involves ion hopping between sites on a lattice (not fixed as in a solid electrolyte such as Agl) with the ions obeying a hopping type equation 

Pj is the probability of finding a mobile ion at site i, Wij is the probability per unit time that an ion will hop from site j to site i and is equal to zero 

In addition to specific applications, the dynamic bond percolation model has been extended to focus on the importance of lattice considerations. The role of correlations among different renewal processes and the
