Summary: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). L'invention concerne une poudre de graphite (partiellement) lithiée enrobée, caractérisée en ce qu'elle est produite à partir de lithium métallique et de graphite pulvérulent selon un procédé non électrochimique et en ce qu'elle est stabilisée hors d'un élément électrochimique par application d'une couche d'enrobage ; un élément galvanique contenant une cathode, un système séparateur d'électrolyte conducteur de lithium et une anode contenant une poudre de graphite (partiellement) lithiée enrobée, la lithiation (partielle) et l'enrobage de la poudre de graphite étant effectués par voie non électrochimique hors (ex-situ) de l'élément galvanique.
