Abstract

The interaction of lithium polysulfides and metals which have shown promise for use as current collector/cell casingmaterials for lithium/sulfur cells is explored using cyclic voltammetry. The metals used were chromium and molybdenum,and data for 10-500 mV/s potential sweeps at 400C in Li2S3.80 are reported. The data were collected using an electrochemicalcell designed specifically for this purpose. The results were analyzed using classical equations governing cyclicvoltammetry, and a model was developed to describe specific melt-metal interactions.
