Title:
METHOD FOR MANUFACTURING A LITHIATED METAL/CARBON COMPOSITE ELECTRODE, LITHIATED METAL/CARBON COMPOSITE ELECTRODE MANUFACTURED BY THE METHOD, AND ELECTROCHEMICAL DEVICE COMPRISING THE ELECTRODE
Document Type and Number:
WIPO Patent Application WO/2012/108741
Kind Code:
A2
Abstract:
The present invention relates to a method for manufacturing a lithiated metal/carbon composite electrode, to a lithiated metal/carbon composite electrode manufactured by the method, and to an electrochemical device comprising the electrode. More particularly, the present invention relates to a method for manufacturing a lithiated metal/carbon composite electrode having a novel structure with superior charge/discharge characteristics and cyclability, to a lithiated metal/carbon composite electrode manufactured by the method, and to an electrochemical device comprising the electrode. The lithiated metal/carbon composite electrode according to the present invention is structured such that lithium and metal form an alloy which is simultaneously inserted into a carbon crystal structure so as to form a composite having a stable structure. Therefore, less variations in the volume of the metal occurs during charging/discharging processes, and thus a degradation in cyclability may be prevented, charging/discharging capacity may be improved, irreversible capacity may be controlled during initial charging/discharging, and a negative electrode using lithium metal, which may be unsafe, may be replaced with the electrode of the present invention.
