Summary: | The present invention relates to an anode pre-lithiation method comprising the steps of: manufacturing an anode by forming, on an anode current collector, an anode active material layer comprising an anode active material; manufacturing a pre-lithiation cell, which comprises the anode and a lithium metal counter electrode, and impregnating the pre-lithiation cell with a pre-lithiation solution; and charging the pre-lithiation cell with a constant voltage to pre-lithiate the anode, wherein the pre-lithiation solution comprises 3-30 vol% of an organic carbonate compound substituted with a halogen atom.
La présente invention concerne un procédé de pré-lithiation d'anode comprenant les étapes consistant à : fabriquer une anode en formant, sur un collecteur de courant d'anode, une couche de matériau actif d'anode comprenant un matériau actif d'anode ; fabriquer une cellule de pré-lithiation, qui comprend l'anode et une contre-électrode de lithium métallique, et l'imprégner la cellule de pré-lithiation avec une solution pré-lithiation ; et charger la cellule de pré-lithiation avec une tension constante pour effectuer une pré-lithiation de l'anode, la solution de pré-lithiation comprenant 3 à 30 pour cent en volume d'un composé de carbonate organique substitué à un atome d'halogène.
