Abstract

A mathematical model has been developed that describes multicomponent transport in solid electrolytes that contain either three or four independent species. The treatment includes homogeneous reactions, short-time transients, and the effects of a co-continuous inert phase. Application of the model to low-frequency AC impedance experiments shows that accurate information on reaction stoichiometries and the nature of the mobile species is needed for proper interpretation of transference numbers and diffusion coefficients. A set of consistency checks for the impedance data is identified that helps distinguish between dilute and concentrated solid ionic conductors and between systems that should be regarded as four-species electrolytes rather than binary electrolytes.
