    摘要： The present invention discloses a method for producing a particulate material for a composite electrode comprising ball milling of an electrode active component comprising a transition metal M having a pristine oxidation state of 5+ and optionally 4+ and/or 3+, and a first lithium-comprising sulphide compound comprising an element X, X being P, Ge, Si or Sn, wherein an electronically conductive component is added to the electrode active component and the first lithium-comprising sulphide compound, thereby obtaining the particulate material. The present invention further discloses a particulate material for a composite electrode comprising an electrode active component comprising at least one transition metal M having an oxidation state in the composite of 3+, 4+, 5+, or a mixture of two or more thereof, a lithium-comprising sulphide compound comprising an element X, X being P, Ge, Si or Sn, and an electronically conductive component, wherein the particulate material comprises one or more of the following bonds: X-S x -X, M y S z , M u X v , wherein x is between 0 and 2, y is between 0 and 2, z is between 0 and 4 and u is between 0 and 2. The present invention further discloses a composite cathode comprising the particulate material and a battery cell comprising the composite cathode.
