Abstract

An equivalent circuit for a porous polycrystalline insertion electrode is presented. This model is found to be inadequate to describe the ac response of the Li_(1-x)CoO₂/LiBF₄ in propylene carbonate interface because of the formation of a Li⁺-ion conducting layer on the surface of the electrode. Lithium diffusion in the electrode is determined by three methods which all indicate a value grater than that reported for TiS₂. © 1986.
