Abstract

A versatile, cost-effective electrochemical analysis strategy is described that determines the specific Sn2- adsorptivity of materials, and allows prediction of the long-term performance of sulphur composite electrodes in Li-S cells. Measurement of nine different materials with varying surface area, and hydrophobicity using this protocol determined optimum properties for capacity stabilization.
