Query: Modeling of aging processes in the insertion compounds   The aging phenomena occurring in the course of cycling processes in the
insertion host-guest compounds are discussed in the framework of a simple
model. It takes into account two types of effects. One can be attributed to
modifications of the host/guest solution interface in a form of an effective
energetic barrier. The other is associated with the host matrix disordering
that is translated into a change in the distribution of the host site energies
as a function of the applied potential or the concentration of the guest
species. It is found that the aging properties depend on the preparation mode,
the cycling conditions and the insertion induced transformations. The impact of
these transformations on the aging is determined by the matrix sensibility.
