POLYACRYLONITRILE-SULFUR COMPOSITE MATERIAL

摘要

The invention relates to a method for producing a polyacrylonitrile-sulfur composite material. In order to provide a polyacrylonitrile-sulfur composite material having a high content of covalently bonded sulfur and thus to increase the capacity or energy density of an alkaline sulfur cell, in particular a lithium sulfur cell, having the polyacrylonitrile-sulfur composite material as a cathode material, according to the method polyacrylonitrile is reacted with sulfur at least for a time in the presence of a catalyst to form a polyacrylonitrile-sulfur composite material. The invention further relates to a polyacrylonitrile-sulfur composite material, to a cathode material, to an alkaline sulfur cell or battery, and to an energy store.
