Insight into the failure mechanism of large-scale cylindrical lithium–sulphur cells

Abstract

Li–S batteries with a sulphur loading content of 5 mg cm−2 were produced as large-scale 18 650 cylindrical cells. We have found that a key failure mode of cylindrical Li–S battery cells is the severe capacity fading during the galvanostatic charge–discharge process due to the corrosion of the electrodes, the electrolyte decomposition, and the severe polysulphide shuttling effect.
