Method for manufacturing a lithiated metal-carbon composite electrode, lithiated metal-carbon composite electrode manufactured thereby, and electrochemical device including the electrode

摘要

The present invention relates to a method for manufacturing a lithiated metal-carbon composite electrode, a lithiated metal-carbon composite electrode manufactured thereby, and an electrochemical device including the electrode. More particularly, the present invention relates to a method for manufacturing a lithiated metal-carbon composite electrode with a new structure having excellent charge/discharge and cycle characteristics, a lithiated metal-carbon composite electrode manufactured thereby, and an electrochemical device including the electrode. In the lithiated metal-carbon composite electrode, lithium is alloyed with a metal and is inserted into a crystal structure of carbon to form the composite having a stable structure. Thus, a volume of the metal is slightly varied, so a cycle characteristic may not be deteriorated and charge/discharge capacities may be improved. The lithiated metal-carbon composite electrode may control an irreversible capacity during initial charging/discharging and may be substituted for an unsafe lithium metal anode.
