Abstract:
We investigate the storage behavior of composites of mixed conductors and insulating phases which are surface-active. Here, extra storage is achieved by specific adsorption. For a master example, we refer to experiments on dispersions of Al2O3 in Ag2Se. Quantitative modeling is applied, suggesting double-layer storage of the heterointerface with silver ions adsorbed on the Al2O3 side and electrons on the Ag2Se side, whereas underpotential deposition of Ag may occur at large coverage.
