Solid-state ionics in energy converters

Solid-state ionics, based on fast ionic transport in solids and characterized by anomalously large diffusion coefficients of ions at room temperature and unipolar conductivity (0.05–0.1 S cm−1), assumed in the last few years great importance in the context of creation and subsequent explanation of mechanisms and kinetics of electrode processes during the work of chemical power sources (CPS). It is demonstrated that products of cathodic reactions possess ionic conduction in a solid phase.
