An electrode, in particular, a cathode, for an electrochemical energy store, in particular, for a lithium cell, including particles having one first lithiatable active material, which is based on a transition metal oxide, wherein the particles or a base body including the particles is/are provided with at least one functional layer, which is lithium ion-conductive and includes at least one redox-active element. An energy store including such an electrode, and a method for manufacturing such an electrode, are also described.

Electrode for a lithium cell

A method is provided for manufacturing a polyacrylonitrile-sulfur composite material, the polyacrylonitrile-sulfur composite material having an sphybrid proportion, with respect to the total carbon atoms included in the composite material, of greater than or equal to 85% including the method steps: a) reaction of polyacrylonitrile with sulfur at a temperature of greater than or equal to 450&#xb0; C., in particular greater than or equal to 550&#xb0; C.; b) immediate purification of the product obtained in method step a); and c) drying the purified product, if necessary. A composite material manufactured in this way may be used in particular in an active material of a cathode of a lithium-ion battery and offers a particularly high rate capacity. In addition, methods are provided for manufacturing an active material for an electrode, a polyacrylonitrile-sulfur composite material and an energy store.

Method for manufacturing a polyacrylonitrile-sulfur composite material

An active material for a cathode of a battery cell which includes a first component containing LiMnO. The first component has been doped with a dopant containing a fluoride of a transition metal. Moreover, a cathode of a battery cell which includes an active material, and a battery cell which includes at least one cathode, are provided.
