Abstract

Described is a coated, (partly) lithiated graphite powder characterized in that it has been produced in a non-electrochemical process from metallic lithium and graphite in powder form and has been stabilized outside an electrochemical cell by application of a coating layer; and a galvanic cell comprising a cathode, a lithium-conductive electrolyte-separator system and an anode comprising a coated, (partly) lithiated graphite powder, where the (partial) lithiation and the coating of the graphite powder are performed non-electrochemically outside the galvanic cell (ex situ).
