The present invention relates to a method for producing a cathode material for an alkali metal-sulphur cell, more particularly a lithium-sulphur cell, wherein at least one polyacrylonitrile-sulphur composite material and elemental sulphur are mixed, in order to increase the voltage, capacity, and energy density of the cell. Furthermore, the present invention relates to an alkali metal-sulphur cell or battery, and also to an energy storage device. |
