Dec 10, 2014 The choosing of carbon nanotubes as the conductive additives is because that it can offer a three-dimensional conductive net work during ball-milling process to prevent the agglomeration of sulfur. Surprisingly, obvious improvement of electrochemical performance can be obtained just by simple wet ball-milling process. 2.
