Abstract
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+; at least one second additional oxide selected from the group consisting of Li, Al, Cu, Fe, Cr, Mn, Sn, Mo, Ni, Sn, Ag, Ru or Ti 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 obtained by the method, a composite cathode comprising the particulate material and a battery cell comprising the composite cathode.
