The main theoretical concepts on ionic conduction at interfaces, especially the space charge layer model, are summarized in the first part of this review: ion trapping or redistribution leads to charge carrier accumulation, depletion or inversion and, consequently, to conductivity changes in composite materials. Experimental confirmations of the space charge layer model and the complementary percolation model are discussed. Major developments of ionic conductor composite materials over the last 25 years are presented in the second part, including lithium and other alkaline ion conductors, copper and silver ion conductors, di- and trivalent cation and anion conductors, glass and polymer composites. Some future trends and research needs are indicated in conclusion.
