  • Polyacrylonitrile-sulphur composite material
    Patent number: 9252425
    Abstract: The invention relates to a method for preparing a polyacrylonitrile-sulfur composite material, in which, polyacrylonitrile is converted to cyclized polyacrylonitrile, and the cyclized polyacrylonitrile is reacted with sulfur to form a polyacrylonitrile-sulfur composite material. By a separation of the preparation method into two partial reactions, the reaction conditions are advantageously able to be optimized for the respective reactions and a cathode material is able to be provided for alkali-sulfur cells with improved electrochemical properties. In addition, the invention relates to a polyacrylonitrile-sulfur composite material, a cathode material, an alkali-sulfur cell or an alkali-sulfur battery as well as to an energy store.
