COMPOSITE MATERIALS FOR LITHIUM-SULFUR BATTERIES

摘要

A sulfur-carbon composite materials comprising (A) at least one carbon composite material comprising (a) a carbonization product of at least one carbonaceous starting material, incorporating (aa) particles of at least one electrically conductive additive, the particles having an aspect ratio of at least 10, and (B) elemental sulfur. In addition, a process for producing the sulfur-carbon composite materials, a cathode materials for electrochemical cells comprising the sulfur-carbon composite materials, the corresponding electrochemical cells and the use of carbon composite materials for production of electrochemical cells.
