Toward standardizing the measurement of electrochemical properties of solid-state electrolytes in lithium batteries

A brief discussion on transport measurements for lithium ion conducting pol ymer electrolytes is given. An engineering approach to obtain a complete se t of transport and thermodynamic properties for a binary salt dissolved in a polymer electrolyte solvent is described. The technique is based on conce ntrated solution theory and requires a minimal amount of experimentation. R esults from measurements on a representative polymer electrolyte system are given. The measured transport and thermodynamic properties of the polymer electrolyte are used to simulate the performance of symmetric Li/polymer/Li cells and compare to experimental data.
